The main part of cylindrical energy saving grid ball mill is
cylinder with small diameter and large length 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 mill’s.
Both ends of the cylinder body adopt rolling bearing instead of the
sliding bearing, which is more energy-saving.
