Cone ball mill is a common type of ball mill in ore dressing production. This machine changes the original structure of the mill and integrates the machine body and the chassis, which can reduce energy consumption by 30%, increase fine particle size, and increase processing energy by 15-20%
The ceramic ball mill is a ball mill made of ceramic. Small capacity is generally suitable for intermittent small batch production of product trial production. It is another new type of energy-saving ball mill equipment for mineral processing machinery.
The rod mill is a mill in which the grinding body loaded in the cylinder is a steel rod. Rod mills are generally of wet overflow type, which can be used as first-level open-circuit grinding and are widely used in the first-level grinding of artificial stone sand, mineral processing plants, and electric power departments of chemical plants.
The classifier is widely used in the beneficiation plant and the ball mill to form a closed loop process to split the ore
Flotation machine is the abbreviation of flotation concentrator, which refers to the mechanical equipment that completes the flotation process.

Feb 01, 1993 1. Introduction Ball mills play an important role in the mineral processing industry of today. Yet as such, they are difficult to study given the closed nature of the operation. Once operating, the ball mill becomes a black box where only input and output materials can be observed, as well as the power draw of the grinding system.
Jul 01, 2016 In this case, the energy split factor of component in the mixture grinding of a ball-and-race mill can be calculated by the following equation (7) S 1 = E sm 1 E sa 1 where S 1 is the energy split factor of component 1, E sa 1 is the specific energy of component 1 to yield the same product t.
