Our construction and mining equipments have been warmly popular all over the world.

Introduction

Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. These mills are sized from 2 t/h to 30 TPH for wet grinding and from 0.5 t/h to 30 TPH for dry grinding. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter. So, ball mills are suitable for both general mining applications such as cement, concrete making and quarry applications.

Structure Features

1.It can be used to the grinder with or without moisture

2.Better operation condition, and the crushing will proceed in the closed machine body with no dust.

3.Reliable function and cheap grinder are convenient for the change.

4.Both the interval operation and the continous operation are avalible.

5.The inert gases can be charged into the machine to replace the air when it crush the explosive materials.

Main Structure

Ball mill’s main structures are including the cylinder, feeder, discharge opening, hollow central axis, bear, transmitting equipment and the lubrication system.
