The performance of a hammer mill is affected by the formation of a circulation layer. In this paper, an airfoil-triangle sieve was designed to destroy the circulation layer and improve the performance of the hammer mill. To determine the optimal design parameters of the airfoil-triangle sieve, three-factor and three-
The original hammer mill dimensions were not suitable to forming by using the casting methods. To product such a hammer suitable to form from Austempered Ductile Iron (ADI) a new design should be carried out taken into account the 1 2 ELE. PLAN

The hammer mill's functioning principle is straightforward. Fig. 2.2 illustrates the principle (a). All that is required is the selection of a suitable engine, crushing hammers/knives, and the material to be crushed. It works on the basis of impact between the rotor's fast-moving hammers and the stationary powder bed.
The First Law of Thermodynamics for a steady-state flow process can be expressed by the following equation [3]: (1) Δ H + Δ u 2 2 + g Δ z = Q - W s In this expression Δ H is the change in enthalpy of the process, Δ u2 /2 is the change in kinetic energy, and g Δ z is the change in potential energy.
