Autogenous ，Semi-autogenous mill

Introduction
This equipment is modified by our experts and with the features of greatly energy saving, no powder pollution, less floor area and large average daily capacity.
Features
Avoid overgrinding and increase output. Materials and water are fed continuously through the central sleeve of one side of barrel; and the qualified final products are discharged into hopper through end face discharging device.
The production expense and installed power are separately reduced by 70% and 60% compared to that of the traditional equipment.
Dust removal unit, screening factory and screening equipments are leaved out, which reduce civil engineering investment, the floor area and the cost of labor power and management.
The max feeding size is 160mm.
Application
It is used for coarse grinding after coarse crushing.
Working principle
The essential component is a cylinder with bigger diameter and smaller length which is slowly revolved via transmission machinery. Materials are fed into central sleeve where ores are fully grinded due to the falling impact and autogenous grinding. Ore materials, which are eligible for the particle size standard and pass through grid plate, are discharged from another side of central sleeve, with the aid of overflow water.
