The motor and grinding rotor are connected by elastic pin coupling, so motor start-up power and energy consumption are reduced. The machine has the advantages of compact structure, good appearance, easy assembly and adjustment.

With rotor ealibrated by dynamic balance and the main shaft fitted with high quality bearing and heavy-duty bearing seat, the bearing has low temperature-increase, and the machine has low vibration and long working life.

The machine adopts a round grinding chamber. Materials are charged from the top and discharged from the bottom. Secondary striking plates are installed on the bottom. The machine adopts radial air-intake method and material turbulent structure to effectively destroy circulation alyer of materials and improve production efficiency.

Wear-resisting hammers are installed on the rotor alternatingly and symmetrically. The rotor rotates in positive and negative directions, which reduces hammer replacement frequency and extend hammer working life.

The machine adopts flexible screen pressing mechanism for fast and convenient screen replacement, scrren pressing is reliable.

Operation door is equipped with a safety interlock device to ensure that the motor can not start when the operation door is open.

Gap between and hammers can be adjusted for coarse grinding and fine grinding, which is suitable to process both poultry/livestock feed and aquatic feed.
