Crack-U-Lators produce narrow particle distributions with a controlled cracking process between longitudinal and/or circumferential cuts on mating rolls. Reduce size to anywhere between 4 to 325 mesh or 4,760 to 50 microns. Less fines produced, meaning better yields and more profit. Complete CIP designs available.
Efficient size reduction is an important factor in the production process in many industries. In the feed industry, individual size reduction is the basis for animal welfare, animal health and fattening success. The benefits of an adapted size reduction for the biomass industry are, for example, higher energy efficiency, more eco-

The percent mass retained in each of the sieve including the bottom pan were found to be 14.04%, 9.99%, 10.50%, 2.52%, 1.86% and 0.76%, respectively. Through sieve analysis, particle size distribution of a specific sample can be obtained. It provides the information on which particles are either too large or too small.
Cutting and chopping are size reduction operations based on shearing through the use of sharp-edged moving elements (knives, blades). The term 'cutting' is usually reserved for operations resulting in particles with fairly regular geometric forms (cubes, juliennes, slices), while the term 'chopping' is applied mainly to random cutting. The variety of cutting …
Size reduction is a mechanical process of breakdown of solids into smaller size particles without altering the state of aggregation of solids. Many solid materials exists/present in sizes that are too large to be used directly. Thus such material must be reduced in size before use. 13.1 Necessity of size reduction.

The Alpine AFG Fluidized Bed Jet Mill is a fluidized jet mill that makes use of an air classifier to accomplish fine grinding and classification in one easy system, similar to the Mikro ACM. However, this mill uses particle-on-particle impact to accomplish this size reduction. It is also pressure shock proof to 10 bar overpressure.
to ensure high efficiency of the process, adeq uate reduction of shape and size of the input material must be used in the design stage. According to H. Rumpf [40] and M.H. Pahl [34], there are four types of the grinding process used to produce elementary particles of the expected size and shape. They were briefly described and explai ned in fig. 2.
Size reduction is an essential and often first operation in preparing biomass for subsequent operations. Size reduction is energy intensive especially for cases where the target particle is small and precise in dimension. Mineral and food industries have developed empirical and semi-empirical equations to calculate energy input for grinding.
Impact size reduction is the act of dealing a forceful blow to the particle so that it breaks apart into smaller pieces, thus reducing its size. The machines that are most commonly used for impact size reduction are hammer mills and pin mills.
