Ball Mill

What is the ball mill

We know ball mill is a piece of equipment for grinding mills materials, and it's widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. There are many types of grinding media suitable for use in a ball mill, each material having its own specific properties and advantages. Key properties of grinding media are size, density, hardness, and composition.

A ball mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.and works on the principle of impact: size reduction is done by impact as the balls drop from near the top of the shell.

MQ Series Ball Mill

Ball mill is one of grinding equipment. In the mineral processing production In only a minority of rich ore, after crushing, sieving after Can be directly sent to the smelting, and most of the ore must be Ground to 0.1-0.074 mm even more fine, make useful mineral As monomer dissociation, and after sorting to send Go smelting, visible grinding is one of the mineral processing production An important process. For fine grinding effect is better than the coarse grinding, fine grinding, When the feed size, generally not more than 65 mm, the most Optimal feed size is below 6 mm. The ball mill wide The pan is used for metal and nonmetal mines, building materials industry Sector operations to smash all kinds of ores and rocks in the.

Working Principle of MQ Series Ball Mill

This machine is of edge transmission, the central discharge, the machine has a material inlet and outlet device, an end cover, a hollow shaft, a cylinder body, a gear reducer, size, motor and other components. The working process of ball mill is the material in the feeding end cover hollow shaft gradually enters the cylinder body, the cylinder body is rotated, produce centrifugal force and the friction force, make the medium (the ball) and ore with the cylinder wall rose to a certain height, by its own weight parabola fall or fall down, ore grinding is mainly depend on the role of grinding medium under the falling impact and during exercise to achieve, the mobile cylinder ore is on time feeding ore pressure to achieve. The hollow shaft is finally from the discharge end cover discharge. Wet grinding, ore water away, dry grinding, air cylinder outer extracted ore is to bring out the. Ball mill is the rotation of the motor through the speed reducer gear drives the small gear running, large gear rotation installation small gear on the cylinder and deceleration, a big gear are rotational speed, is a tube running start work.

The new structure of the ball mill

New type ball mill adopts steel casting cylinder, inlaid with a high wear resistant lining board, the machine is designed by adopting new technology, abandon the old production of ball milling process, using edge gear transmission, effectively improve the production efficiency of the mill and mill service life of the machine, the cylinder body is provided with a high manganese steel ball, greatly improving the cylinder body wear life, the machine can make the production efficiency is improved by more than thirty percent, in addition, our company also produces dry, wet ball mill, cone, cylinder, high efficiency and energy saving ball mill, also I can according to user requirements in the production of non-standard custom-made mill, mill.

Milling Time of ball mill

The longer a ball mill operates, the smaller the particles will become. They will even reach the sub-micron level if the mill is allowed to run long enough. Always use as little material in the barrel as possible for maximum grinding efficiency. The more of your material you place in the barrel, the more it will cushion the impact of the media, reducing the grinding action. Several small capacity runs are much better than one long run with your barrel packed to capacity with the material you want to powder.

Advantages of the ball mill

Ball milling boasts several advantages over other systems: the cost of installation, power and grinding medium is low; it is suitable for both batch and continuous operation, similarly it is suitable for open as well as closed circuit grinding and is applicable for materials of all degrees of hardness.
