Aluminum ore belongs to metal ore, it has high hardness. Its processing is different with other non-metallic minerals.

 

Kefid is Asia's high-end production and export base of crushing and grinding equipment, we produce jaw crusher, cone crusher (hydraulic and spring), impact crusher, sand making machine, ball mill, vertical mill, raymond mill,etc. According to aluminum ore characteristics and application requirements,we designed full set of aluminum ore solutions for global customers.

                                                                                 

 

Aluminum ore processing technology include three stages: crushing, grinding, beneficiation.

 

The first stage: crushing and screening

 

Chunks of aluminum ore are sent by vibrating feeder to jaw crusher or mobile jaw crusher for coarse crushing; then after sieving by vibrating screen,the crushed stone are transffered by belt conveyor to single-cylinder hydraulic cone crusher for secondary crushing; finally into multi-cylinder hydraulic cone crusher for fine crushing.We can adjust the fineness to reach 13mm or less.

 

The second stage: milling

 

The crushed aluminum ore are sent into ball mill for grinding and screening by spiral classifier. The products which does not meet the requirements will be fed into the ball mill for re-grinding.

 

The third stage: beneficiation

 

The aluminum powder which meet the requirements are send into flotation machines for flotation and then fed into the dryer to obtain final powder.
