Ecochicks 4 in 1 animal feed machine is an ideal farm machine for farmers having few livestock. It is durable, long lasting and low maintenance machine. It cuts the fodder uniformly, which is ideal for the livestock and It reduces wastage of fodder. It comes in varying types i.e.: Electric – running on a 3HP electric Single-phase or 3-phase motor

Grinding Parameters and their Effects on the Quality of ...

Other grinding types such as creep feed grinding are also performed. This type has the same kinematics of surface grinding, but also has a unique distinction as it removes a high amount of material from the workpiece. To help achieve the high removal rate, the workpiece speed should be low with a high-power grinding machine [3]. Usually the ...
