Semiautogenous (SAG) mills are widely used grinding equipment, but some ore with critical particle sizes cannot be effectively processed by SAG mills and turned into pebbles. This research aims to analyze and compare the properties of raw ore and pebbles from a zinc and tinbearing ore. The results show that the contents of sphalerite, cassiterite, biotite, antigorite, pyroxferroite ...

Smaller tabletop Ball Mills such as ours are useful for grinding granular materials with a particle size up to about 1/4" into a fine dust. There are some materials that our Ball Mills can grind into a powder even if the particle size is very large, like charcoal and similar products that will crush easily.

The beneficiation process flow sheet varies from location to location according to the ore characteristics. For example, the Kemi concentrator in Finland comprises three stages: crushing (jaw and cone crushers) followed by twostage grinding (rod mill and ball mill), followed by a combination of drum, cone, and highgradient magnetic separation.

The important beneficiation process in the chrome processing plant mainly include comminution and concentration. 1. Comminution. Chrome lump ore, or chrome stone, must be crushed and ground into powder due to medium and fine dissemination grain sizes to liberate more chrome mineral. While chromite sand ore does not need the two steps.

Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
