Ball mill is the key equipment for crushing materials after crushing. It is widely used in the production of cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, and glass ceramics.
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 classifier is widely used in the beneficiation plant and the ball mill to form a closed loop process to split the ore
Magnetic separator is used to re-use powdered granules to remove iron powder and other screening equipment.
Flotation machine is the abbreviation of flotation concentrator, which refers to the mechanical equipment that completes the flotation process.
Shaking table is also known as gravity shaking table or concentrator table.
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%
