JKTech Laboratory Services Bond Ball Mill Index Test (BRMWI) A Bond Ball Mill Index Test (BBMWI) is a standard test for determining the Ball Mill Work Index of a sample of ore The BBMWI is a measure of the resistance of the material to crushing and grinding It can be used to determine the grinding power required for a given throughput of material under ball mill grinding consitions JKTech

Grinding Mills

Semi-Autogenous (SAG) Mills:-SAG mill is similar to AG mills but utilizes grinding balls to aid grinding just like ball mills It uses a ball charge of approx 6 - 15% SAG mills are characterized by their large diameter and short length as compared to ball mills SAG mills are primarily used in the gold copper and platinum industries with applications also in the lead zinc silver alumina

Mining Industry: What is the difference of ball mill

Most mills used in mining rely on impact to breakdown rock to a suitable size for downstream processing The impact can be rock on rock such as in an Autogenous Grinding (AG) mill rock and a small ball charge (~10%) used in Semi Autogenous Grind

Ball Mill: Operating principles components Uses

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size The large balls tend to break down the coarse feed

What Leads to the Abrasion of the Cement Ball Mill

The main reasons that lead to the abrasion of the ball mill are: First the big impact force causes microscopic wear which mainly appears somewhere inside the machine people cannot see Second the big impact force leads to the deformation of the cement ball mill At last the abrasion is brought by the corrosion The wear of the cement ball mill lining plate mainly accounts for the type and
