The production line for laterite chromite red clay chrome ore mainly uses vibrating screens and spiral chutes. The vibrating screen is used to remove coarse particles that are not suitable for entering the spiral chute, while the spiral chute is the best separation equipment for chromite. After two to three rounds of beneficiation through the spiral chute, chrome concentrate with a grade of over 48% can be obtained. However, if the raw ore contains a large amount of block shaped ore, it is necessary to add crushers and ball mills for crushing and grinding, and then enter the spiral chute for beneficiation after grinding the raw ore to the appropriate particle size.
