ball mill

Overview

Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or large-scale ore beneficiation plant.

  • Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble. Due to the lack of water resources in some arid areas, dry grinding can also be used in order to save water.
  • Wet grinding: suitable for most materials, various metal ores and non-metal ores. Common ones include gold ore, copper ore, iron ore, molybdenum ore, phosphorus ore, feldspar ore, fluorite ore, etc.

Types: Mining ball mills are divided into two categories, Overflow ball mills: center discharge ball mills; Lattice type ball mills: Peripheral row ore type ball mills.
Batch small ball mill: control the particle size of the material by adjusting the grinding time.

Advantages

  • The ball mill can efficiently and finely grind various materials with different hardness and abrasion properties, including metallic ores, non-metallic ores, cement clinker, etc.
  • It has a highly automated control system, including automatic start and stop, adjustment of grinding speed and addition of grinding media to improve the convenience of operation;
  • Our grinding equipment has large processing capacity and can meet the high output needs of mining and metallurgical enterprises.
  • JXSC ball mill is designed to be energy-saving and environmentally friendly. It often forms a closed-circuit ring grinding device with a spiral classifier to produce powder with a relatively uniform particle size.

working principle of ball mill

The material is fed into the barrel of the ball mill through the hollow shaft. The cylinder of the ball mill is driven by the motor to rotate, and the materials and media in the cylinder rotate at a certain speed to move, and the forces included include gravity, centrifugal force and friction. When the grinding medium reaches a certain height with the cylinder, when the self-weight is greater than the centrifugal force, it will break away from the inner wall of the cylinder and fall or roll down. As the gravitational potential energy is converted into kinetic energy when falling, the steel ball will eventually collide with the ore at a certain final speed, and the ore will be crushed by the impact force. The crushed and qualified materials are discharged through the ore discharge port.
