■ GRINDING
Autogenous Mill
Principle
The main component is a cylinder with a larger diameter and
shorter length. Driven by the transmission device, the cylinder
rotates slowly with the materials fed from the center sleeve at
one end of the cylinder and crushed by the falling impacts and
autogenous grinding of the ores in the cylinder. Qualified materials
flow from center sleeve at the other end of the cylinder through
the grid plate by the overflow water.
Features
Low power consumption, no dust pollution, less auxiliary
equipment, easy production automation, and stable particle size;
Autogenous mill can realize the second and third stage crushing
and screening, and part or all crushing and grinding of rod mill or
ball mill;

Autogenous mill can process coarse ores with intermediate
crushing and fine crushing saved, high crushing ratio, which can
reach 3000-4000.
Application
Generally used in the coarse grinding after coarse crushing.

Cylindrical Energy-Saving Grid Ball Mill with Rolling Bearing
Principle
The main component is a cylinder with smaller diameter and larger
length. Driven by the transmission device, the cylinder rotates slowly
with the materials fed from the cylinder inlet and crushed by the
falling impacts and autogenous grinding of the steel balls and ores in
the cylinder. Due to the continuously feeding materials, Materials are
pushed to the outlet by the pressure, and the grinded materials are
discharged from the cylinder outlet. Qualified materials flow from the
cylinder outlet. In wet grinding, the materials are taken out by the
water flow; in dry grinding, the materials are taken out by air. There
is a grid installed in the outlet of the mill with low pulp surface, which
can reduce the ore over-grinding, and prevent the steel ball out.
Under the same production conditions, production capacity of grid
mill is larger with rolling bearing and significant energy conservation.
