AI Technical Summary
In traditional hammer mills, the material movement is chaotic during the rice crushing process, resulting in some particles not being fully crushed and requiring secondary screening, which reduces production efficiency and increases energy consumption.
The design incorporates a differential rotation between the throwing component and the rotor. The throwing component throws insufficiently crushed material up to the hammer impact area for further crushing. Combined with a planetary gear reduction mechanism, differential rotation is achieved to ensure uniform crushing of the material.
It improves the efficiency and thoroughness of single-pass crushing, avoids material accumulation, ensures uniform output, reduces secondary screening steps, and improves product quality.
