Batch mixing or continuous mixing? This short article will cover whether or not a continuous mixer is most appropriate for your production line. Batch mixing Mixing can be done in two ways: through batch mixing or continuous mixing. Batch mixing involves measuring a set quantity of ingredients and then processing it through the mixer. This is repeated for each batch, with the mixer being filled and emptied each time. Continuous mixing Continuous mixing involves processing the ingredients in a continuous stream without any starting and stopping. The mixer operates continuously, with the ingredients being fed into the mixing chamber and then being continuously discharged. The continuous mixing process eliminates the need for separate steps such as filling, mixing, and emptying, streamlining the production process and increasing efficiency. Batch vs continuous mixing in practice By far, most powder mixing processes are executed with a batch mixer. However, continuous mixing offers advantages in certain circumstances. To understand these circumstances, consider your needs regarding production capacity,

A series of innovations in the powder blending machine design has led to the successful execution of the newest Lindor mixer, specially designed and optimized for battery powder processing. DORDRECHT, The Netherlands, 15 December 2022 — Lindor, manufacturer of specialized gentle touch mixers, sends out a new, state-of-the-art battery powder mixer for delivery to a client in Japan. The demand for battery powder is soaring. According to Statista, the size of the global lithium-ion battery market is projected to grow by over 72% by 2026, which puts pressure on battery manufacturers to scale production quickly. However, battery powder comes with a unique set of challenges for manufacturers- namely regarding the risk of metal ingress. Lindor has been engaged in battery powder mixing projects for well over 20 years. The unique gentle touch technology with which Lindor mixers operate is particularly well-suited for powders that are especially sensitive to metal contamination, as there are no moving parts within the mixing drum. To answer the demand from battery manufacturers to develop brand-new production plants or install additional processing

Does a mixer immediately come to mind when you think about polymer processing equipment? If not, it certainly should. Mixing as the next step after the polymer extrusion process A post-extrusion polymer mixer achieves an even distribution of cross-linking agent across your polymer pellets in a temperature-controlled and hyper-clean environment. With a Lindor post-extrusion mixer, you achieve these results all while protecting the integrity of the particles as well. This special mixer has been designed to fit into your production line directly after your plastic extruder machine. Freshly extruded material enters the inlet of the mixer and then undergoes a treatment while being blended. The final product is a perfect polymer blend of pellets ready to be cross-linked in the next extrusion process with a level of quality appropriate for the manufacturing of products like heavy-duty wire insulation. Polymer blend compounding and processing features explained By enhancing our gentle touch rotary drum mixer with three important features, Lindor has developed a highly specialized and

Due to the extremely cohesive properties of very specific types of powders, a challenge can arise in getting these powders to flow. For over three decades, Lindor has been manufacturing industrial mixers and processing machines for powders, granulates and bulk solids. Among the large variety of applications our powder blenders have been built for, there are a few exceptional powders that tend to cause a fuss. Due to the extremely cohesive properties of very specific types of powders, a challenge can arise in getting these powders to flow from one section of a machine into the next. We like to refer to them as ’sticky powders’, and these exceptional powders include: # Battery powder # Fine minerals # Fine ceramics # Pigments After having experienced a challenge in the powder flow from the inlet to the drum of our mixer machine, we decided to come up with an innovative improvement for these very special powders. Tackling flowability challenge For almost all powders, a special coating like Teflon within Lindor powder mixers, along with the water blasting and mirror polishing, is

At the upcoming POWTECH fair, Lindor will be showcasing 3 special machines: a small laboratory mixer, the Gull Wing mixer and the Lindor Capsule© vacuum drying and coating machine Lindor at POWTECH in Hall 3 at Stand 3-163. Three Special Mixers on Display Each of the 3 mixers we will have on display at POWTECH 2022 have been designed with the gentle touch technology which Lindor has developed for mixing and processing fine powders, granulates and natural products. 1. L10 Lab Mixer The smallest mixer in our product range, the L10 laboratory mixer, can hold up to 10 liters of product and is equipped with a transparent drum so you can see exactly how particles flow while they are being mixed. This mixer is especially useful for small batch testing and R&D activities. 2. Gull Wing Mixer The Gull Wing mixer is a 1000-liter batch capacity mixer with hatches resembling luxury car doors or sea ”gull” wings. The double hatch feature was initially created for a client who sought an easier method for cleaning and has now become a standard option available for all the mixers on our product line. 3. Lindor Capsule© The Lindor Capsule©

To date, Weishardt runs 3 Lindor L25000 mixers in 3 factory locations, with their latest order just installed in their newly opened production site. The first company to super-size their mixer and, in effect, extended the Lindor product range to the XXL L25000 in the 2004, was French gelatin pioneer: Weishardt. The concept was simple enough; they required a large capacity industrial blender the size of a tanker truck tank for the homogenous mixing of gelatin powder and granulate. The realization of the concept was, however, far from simple. Flash forward to today, their 3rd XXL Lindor mixer has just been installed in their newly opened plant in Graulhet, France where collagen is being blended. A bespoke solution in mixing technology Weishardt’s need for a 25,000-liter mixer drove the innovation which resulted in the Lindor L25000, the world’s largest powder mixer of its kind. At the time of the inquiry 18 years ago, the Lindor factory was not structurally capable of hoisting such a giant. A solid 20 tons of metal with a 12,5-ton rotating mass; it was even too heavy for the factory floors to bear.

The machine supplied by Lindor mixes, coats, dries and roasts, and all on a surface of only 4 by 4 metres. The final process is simple and efficient. When Lindor contacted a German trader and processor of exotic fruit, no one could have imagined that this would result in a unique mixer that combines all four processes in one mixer. The machine supplied by Lindor mixes, coats, dries and roasts, and all on a surface of only 4 by 4 metres. The customer is a progressive company, with a varied range of organic Fair Trade exotic fruit. “The company needed a more efficient way to produce the sweetened fruit flakes,” explains Michael Kaiser, Lindor’s Sales Manager Germany. “The caramelised flakes proved to be a popular product, but the caramelisation process was very labour-intensive and time-consuming. From mixer to versatile processing machine ”During the decades that we have been producing mixers, we have noticed that our mixers are a great platform for doing more than simply mixing. Before long, a customer asked us whether it would be possible to spray liquid onto the product during the mixing process.

Lindor rotary drum blenders are increasingly finding their way into the plastics industry. Also in special cases: the mixing drum used as ‘cyclone’ in a pneumatic conveyor system. The ‘gentle touch’ mixing principle is suitable for a wide range of applications such as ‘dusting’ sticky granulates. The gentle touch mixing principle of Lindor rotary drum blenders ensures that the quality of the components remains intact. There is little or no product break-up, dust formation and heating up. Thanks to the usually good running properties of plastics the mixing times can be short. This means that high capacities can be achieved, certainly in the case of a continuous mixing process. For example capacities of 5 to 15 (and even 20) tonnes/hour. An innovative option to simplify the production process for a batch mixer is the use of the mixing drum as a ‘cyclone’ in a pneumatic conveyor system. By creating a vacuum the granules can be aspirated directly from the silo into the mixer. Rotary drum blenders are therefore particularly suitable for many applications in the plastics industry. Homogenisation An important application of Lindor

Machine homogenisation of sensitive, high-quality vegetable seeds on a large scale, without damaging the seeds. It seemed an ambitious project: homogenising large quantities of fragile, high-quality vegetable seeds by machine without causing any damage to the seeds. Nevertheless, in collaboration with Rijk Zwaan, a global player in vegetable breeding, Lindor successfully developed a mixer which homogenises and blends seeds and fruit crops while maintaining a consistent quality. “Cucumber seed is very fragile which, once damaged, you can’t sell. Lindor’s gentle touch technology is a perfect match for our products”, says René Hendriks, team leader of Operations Support at Rijk Zwaan. Homogenise shape and size Continuous innovation is essential if, as an international player, you want to deliver top quality and participate in the development of new varieties, a company philosophy that Rijk Zwaan embraces. However, it becomes a lot more challenging when you’re dealing with a delicate product that also has to be packed precisely to the gram. “We pack spinach seeds

Michael Kaiser, salesmanager Lindor Germany: Lindor will benefit from corona from 2021 onwards. Lindor is known for its innovative spirit, high-end technology, and responsiveness to new opportunities in a changing market. As a global supplier of powder and granular mixers, coolers and impregnation, coating and drying systems, Lindor is one of the main players in niche markets, which, despite the corona crisis, are facing a bright future. These are the words of Michael Kaiser, sales manager of Lindor Germany: ‘Lindor will benefit from corona from 2021 onwards. Innovative, high-quality companies will emerge from the crisis undiminished.’ The demand for food and drink will always be there. Even during the disruptive market crisis we are currently experiencing, the demand for food processing machinery will be unaffected. However, according to Kaiser, Lindor is being forced to innovate more than ever as the corona crisis means that the world will need to digitize at a rapid pace. But it is still mainly trends that, according to the sales manager, guide the company`s

Because of coronavirus, many trade fairs and events did not take place last year. A missed opportunity to meet and show you our latest developments. We have not been idle over the past year, and have been working on some special and challenging projects that we would like to share with you. Mixer-Cooler for battery powder Lindor has developed two large Mixer-Coolers for the production of battery powders for a large international project. Despite the corona pandemic, the project provided a rewarding international cooperation between the European customer, a Chinese engineering team and a Scandinavian installation team. The Mixer-Coolers feature a new technical innovation, in which a very thin, heat-conducting ceramic coating is applied to all contact parts. This ensures that no contact occurs between the battery powder and the metal of the drum wall. The drum itself has a double wall and double vanes through which cooling water flows as the drum rotates. Due to the

Did you know that our mixers can very gently mix brittle dried insects and even live matter, such as insect eggs? Our drum mixer with ‘gentle touch’ technology is located in the breeding grounds of a renowned insect breeder in Asia, and provides insect eggs with a nourishing shell. Once hatched, the little ones imagine themselves to be in the land of plenty, which stimulates them to transform faster. Billions of eggs When processing insect eggs, it’s more about volume and less about weight. Just one gram contains 40 - 50 thousand eggs. It’s a huge challenge to mix millions of eggs homogeneously with another solid, and to still keep them alive in the process. By applying our ‘gentle touch technology’, more than 97 percent of the eggs emerge from the mixing process undamaged. This is because our mixer works in batches for optimal mixing. Successful trials Extensive trials at the Lindor test centre show that the Gentle Touch drum mixer perfectly mixes a batch

For our recent client, manufacturer of special cosmetics, Lindor`s unique gentle-touch technology proves to be a perfect solution for mixing sensitive substances. “Gentle-touch technology is a huge improvement for a safer production process,” says the operations manager, talking about the purchase of the Lindor L1500 mixer. The mixing machine is at the heart of production. It ensures that different ingredients, such as fine powders, granulates and natural products, are well mixed and processed into the required end product. Very sensitive, fragile products require a different way of processing. To meet this demand, Lindor developed gentle-touch technology, an efficient way of mixing. This uses natural gravity without the risk of breakage, heat or smearing by friction. Explosive substances Thorough and quick mixing can be dangerous when working with sensitive or even explosive substances, as in this case. As there were doubts about the quality and safety of the

It is becoming increasingly important to mix cocoa very meticulously For consumers, price is not the most important aspect, it’s the quality of the chocolate. Our gentle touch mixing technology fully complies with this trend. Without any concessions to the quality, texture and flavour, Lindor mixers mix the cocoa powders and, where required, the beans, with batches of other products. Gravity does most of the work Fixed vanes in a rotating drum carry the beans around, while gravity does the work of mixing the product. Apart from gravity, no other force is exerted on the product in a Lindor mixer, as is usually the case with other mixers. There is no (frictional) heat, the powder particles and the beans remain intact, are not deformed and oils and fats are not forced out. This unique method also has animportant advantage: very low power consumption of less than 1kW for a batch of 500kg. The design also has its advantages. Because of the shape of the vanes, the mixing time is very short, it empties quickly and completely, and is

Even after 26 years of loyal service, Lindor mixers are not ready for retirement Lindor welcomes companies interested in a pre-owned gentle touch mixer. These mixers are available quickly and, after reconditioning, are supplied under guarantee. An ideal solution for companies with a limited budget or an urgent need for a mixer. An increasing occurrence is that a company’s old Lindor mixer is still operating satisfactorily, but needs to be replaced due to increasingly stringent food safety requirements. In these cases, the customer has the option of exchanging the old mixer for a new one. Lindor then reconditions the old mixer, making it suitable for many years of service in other applications. Superfast delivery When a plant needs a mixer at very short notice, a reconditioned mixer may provide the perfect solution. Depending on circumstances and requirements, a pre-owned mixer can be delivered within two to four weeks. The delivery time for a new mixer is usually 16 to 20 weeks or longer. From instant products to detergents The very

Lindor who are based in the Netherlands have designed and built a special heated mixer for Switzerland based BUSS AG. The mixing drum has been designed using state of the art technologies. The heated mixer is being used for enhancing product characteristics of special compounds which are produced by BUSS compounding lines in several countries. BUSS AG is a global market leader in building special process equipment such as kneaders for producing (plastic) compounds. In the process of producing special HDPE and LDPE compounds, the Lindor mixer with heated mixing drum, is used for soaking the granulate with a special liquid. Also while mixing, the heated liquid is being sprayed onto the granulate, which enables the materials to gain the required characteristics within a defined conversion time. Mr. Hans Hügel, Sales Manager Overseas Business at BUSS AG, comments: “We have been working together with Lindor for about five years and we have integrated the heated

The Dutch Agro-Industrial Group "Royal Cosun" is currently building a pilot plant for developing processes for getting the most out of their raw materials and by-products. Cosun Food Technology Centre (CFTC), has approached Lindor specifically for mixing and drying of their products after the processing of their by-products. For these products the mixing and even more importantly the drying, should be conducted in a controlled manner without any side effects. The bio refining process Cosun wants to extract as much as possible from the crops they use. In the pilot plant the crop will be completely taken apart in several stages for conversion into valuable and useful new products. All kinds of materials originating from the cells will be converted to products used in the food, animal feed and chemical industries. The remaining bio mass will be used to generate "green energy". Cosun"s objective is to make the most of their crops in an economical
