The thickness of magnetic liner is very thin. It is about 4050% of high manganese steel liner. It can effectively reduce the load of ball mill, reduce the consumption of ball mill and increase the volume of ball mill. （3）Noise is low, drop ball consumption. A large number of crushed balls are adsorbed on the surface of magnetic liner.
PEPL PEPL INTRODUCTION The Electronic Ear type PI 213 is a magnetic Sensor also know as Sound Transmitter, which is using the mill shell as Membrane. This means the Sensor is only detecting the mill shell vibrations, caused by the Grinding balls hitting the mill lining and material in the mill, and so the Pyrotech Noise Level Sound Transmitter system is insensitive to foreign acoustic noise ...
Magnetic liners can improve the performance of ball mills by increasing grinding efficiency, extending service life, and reducing maintenance costs. Despite their importance, the fundamental understanding and the quantitative investigation on the effects of the magnetic liners has not been addressed in the literature.
The term ball mill is restricted to those having a length to diameter ratio of to 1 and less. Ball mills in which the length to diameter ratio is between 3 and 5 are designated tube mills. These are sometimes divided into several longitudinal compartments, each having a different charge composition; the charges can be steel balls or rods ...
of ball mill liner. According to the material, commonly used liners include low alloy liners, high manganese steel liners, rubber liners and magnetic liners. Lowalloy liner and high ...
The magnetic lining plate of the ball mill, disclosed by the invention, has the advantage of higher ore milling efficiency and is especially suitable for autogenous mills, semiautogenous...
The installation method and sequence for all types of ball mills are roughly the same. To ensure smooth operation of the ball mill and to reduce the risk to the building, the ball mill must be installed on a reinforced concrete foundation of to 3 times of its weight. The foundation should be laid on solid soil and should be at least 4050 ...
The life of the magnetic mill liner depends on the discharge type, mill diameter, ball size, magnetic permeability of ball and magnetic mineral content in feed. It has been observed that the MML lasts two to three times longer than rubber or metallic liners. ... Mill lining costs account for up to 5 % of the overall cost of mineral processing ...
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc., as well as for ore dressing of ferrous and nonferrous metals. The ball mill can grind ores and other materials, wet or dry.
Pulp level from the mill center line, y 1, is approximately ... In a horizontal ball mill, magnetic liners are subject to ball falling impact and ball attrition. The ball falling impacts have been studied by simulating ball motions in the mill pulp. Different mill sizes and different ball sizes have been included in this study.
