The particle size could be controlled to be as large as grits or as fine as 100 micron. This range typically covers the different flour types used in bakery, confectionary, extrusion and pasta. Source: Inc. Process Features. The rotor speed, feed rate, screen size, screen type, and moisture content of peas all affect pea milling quality.
Ultra-fine Particle Grinding. OGL's cryo grinding process produces much more finely ground particles than conventional milling methods. OGL cryo mills are able to grind many materials to 10µm average particle size or smaller. This improves the particle flow of polymers and dispersion potential for processed polymers and foodstuffs in liquid.
3.2 Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.
