Grid ball mill is a grinding mill with discharging grid and will grind the big size ore into small or fine. It is usually used in the first stage grinding to produce coarse particle product and  can work at wet or dry way. Grid ball mill is widely used for electric power, ferrous metal and nonferrous metal, chemical industry and building materials etc.

Features of grid ball mill

1.Advanced sealing technology, to ensure good working environment.
2.The use of advanced design means, to ensure safe and reliable mill.
3.Mature and strict processing and detection means, to ensure the quality and accuracy.
4.With a strong brand manufacturers at home and abroad, to ensure the quality of the machine running.
5.The machine is equipped with a complete turning, jacking device and tool installation and maintenance.

Working principle of grid ball mill

The main part of grid ball mill is a rotation cylinder rotating slowly by the transmission device. The material is fed from the cylinder inlet and grinded by the impact of steel ball and ore and self-grinding. Due to the continuously feeding material, the pressure pushes material to the outlet and the grinded material is discharged from the cylinder outlet. In wet grinding, material is taken out; in dry grinding, the material is taken out by air. The grid installed in the outlet of mill is relied for forced discharge. Low pulp surface in cylinder reduces the ore over-grinding, and prevent the steel ball out. Under the same production conditions, production capacity of grid mill is larger than overflow ball mill's.
