pellets exhibit many side bending and crack

This is generally in a particulate material produced when leaving the ring mold. In production, when the cutter position adjustment is too far away from the surface of the ring mold and blunt edge, oil expeller from the The extrusion die orifice is touched off cutter instead of being cut or torn, this time some particulate material and the other side bent to one side exhibit many cracks. The pellet Entering the cooler or during transport, often from these cracks at fracture, causing the production of excessive particulate material powder.
Ways to improve it:
 a) increasing the compression ring die for feed force, which increases the compression ratio of the ring mold, Food dehydrator increasing the density of the granules and hardness values;
 b) some of the raw material more finely pulverized, if you add the molasses or fat, molasses or fats should improve the distribution uniformity and control of the amount added in order to improve Pieces The density of pellets to prevent feed soft;
c) adjusting the knife away from the surface of the ring mold, usually the outer edge surface of the ring mold from a distance not greater than the diameter of the particles produced, or replace the use of more front Lee cutting blades, for particles of small diameter thin blade material can also be used, and to a thin surface of the blade close to the ring mold production;
d) Use of adhesive class granulation aids, help to improve the binding force within the particles.
