Determination of the average size of preliminary grinded wet feed particles in hammer grinders

In the conditions of farms, it becomes necessary to grind feed that has a different degree moisture. Therefore, choice universal working bodies is object research, and theoretical determination average size pre-crushed particles great scientific practical importance problem needs be solved. Proceeding from this, constructive-technological scheme grinder with grinding body proposed. The apparatus equipped hammer which cutting edges. this case, hammers edges crush wet mass, also create an air flow work as accelerators at high speed. As result studies, steps for arranging these were determined. Analytical expressions are obtained determining length depending on distance between faces replaceable knife bodies, i.e. step them in rows. At same time, calculation results showed 20 mm, value grinded was 38.38 mm. raw materials intended farm animals 37.64 i. e. difference actual only 2.0 %. This proves reliability analytical expression, provides main parameter body, spacing radial knives proposed method crushed allows theoretically finding planning required particle
