Processing raw materials: Why cracking is better than grinding
Whilst at VIV Europe 2018, in Utrecht, the Netherlands, Milling and Grain spoke to Ben Janssen Bouwmeester a supplier of new technology including the "MULTICRACKER", originally designed by Makoba and produced in Germany.
Makoba offer resource-saving solutions for the comminution of bulk materials in animal feed, food and chemical industries and for comparable applications.
They reference the following product and research by saying, "At the heart of our offering are the patented MULTICRACKER mills, which are used in a variety of different applications."
Energy saving is becoming more important and we are determined to ensure our contributions continue to deliver. During this development we focus on efficiency and cost reduction – we have the proof that this has succeeded!
We can say with certainty, that the MULTICRACKER, thanks to the patented crack writing, the most efficient crusher is there, it exists.
The MULTICRACKER reduces your size products with a minimum energy consumption.
Grinding raw materials has long been a traditional way of processing grains, oilseeds and legumes, but now a Dutch company is introducing an innovative new machine that "cracks" these and other raw materials. There are many advantages to the new technology, beginning with a large reduction in energy costs.
Milling raw materials
The MULTICRACKER is a compact machine with which products can be reduced. In this process, the initial product is cracked (broken) instead of ground. The machine"s housing contains an intersecting series of patented crack discs that crack the product under high speed to the desired size.
The rows of intersecting disks within the MULTICRACKER perform a shearing action that is similar to the effect of a pair of scissors. Thanks to this innovative cutting process and the optimum cutting geometry, the product can process material quickly and precisely reduce them to a pre-set size.
One major characteristic is the unit"s energy efficiency. It achieves an extraordinarily high throughput while offering low power consumption so that operating costs remain low.
Why crack (break) instead of grinding?
By cracking the product, a uniform size is achieved. In the case of animal feed, this has a positive effect on the digestion of the animal.
Another advantage: due to the rapid transit of raw materials through the machine, no heating of the product occurs. This results in minimal moisture loss and the end product retains its nutritional value.
• Multifunctional use;
• Efficient processing of valuable raw materials;
• Homogeneous structure of finished product;
• Processes both dry, oily and moist products;
• No heating of product;
• Simple and accurate operation;
• Compact and lightweight construction;
• Long lifespan.
