Laboratory dry type gold processing ball mill machine for both wet and dry fine grinding

Product Description

Ball Mill Introduction

There are three main stages to mineral processing in the mining industry. These are:

* Comminution (crushing and grinding).
* Beneficiation (separation and concentration).
* Smelting and refining.

Ball mills are employed in the comminution stage as grinding machines (size reduction). The purpose of grinders in the mining industry is to reduce the feed material size in order to liberate the minerals from the barren rock. Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage, or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semi-autogenous grinding (SAG) mill followed by a ball mill (two stage circuit). Smaller plants tend to add extra crushing stages in order to operate a single grinding stage only. If a ball mill uses little or no water during grinding, it is a ‘dry’ mill. If a ball mill uses water during grinding, it is a ‘wet’ mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher. Secondary grinders are fed from other grinders e.g. a rod mill. Ball mills are usually either of the grate (diaphragm) or overflow type.

Ball Mill Components

Ball mills consist of the following components:
* Inlet – crushed ore is fed to the ball mill through the inlet. A scoop ensures the feed to the mill is constant.
* Discharge – reduced feed exits the mill through the discharge.

Ball Mill Components

* Drum – the drum is the cylindrical casing of the ball mill. The inside of the drum is fitted with manganese steel alloy plates (‘armour’) that protect the steel shell from abrasion; it is also possible to use rubber as armour rather than manganese steel.

* Ring Gear – a gear ring installed on the outer periphery of the drum.
* Electric Motor – a motor used to rotate the drum. The motor drive train leads to a gearbox than a ring gear. The motor is
usually fitted with a variable speed drive (VSD) to control the rpm of the ball mill.
* Gearbox – used for speed reduction from the motor to the ball mill.
* Balls – usually manufactured from manganese alloy steel, but the material depends upon for what material the mill will grind (chrome steel alloy and rubber also available). The size of the balls depends upon the size of the drum, typical ball sizes are two to three inches in diameter (four-inch balls are also possible).
* Bearings - smaller ball mills use anti-friction cylindrical roller bearings. Larger ball mills use trunnion bearings.
