Chrome washing plant refers to the facility that processes chrome ore through washing, screening, separation, and other processes to obtain chrome concentrate. Chrome ore mining equipment is the machinery used in this process. The following is an introduction to the main equipment:
Feeding Equipment: Commonly used feeding equipment includes vibrating feeders, feed hoppers, belt feeders, etc. These devices can evenly feed the chrome ore into the subsequent processing equipment. A grizzly bar is usually installed on the vibrating feeder or hopper to remove large waste rocks.
Washing Equipment
Rotary Screen: Also known as a trommel screen, it is suitable for chrome ore with a small amount of sticky mud. It can screen and clean materials according to particle size, and the non - blocking screen can effectively remove mud and impurities.
Rotary Washing Machine: For chrome ore with a large amount of mud, the washing drum of this equipment is long, and the material stays in the drum for a long time. With the assistance of high - pressure flushing water, it can strongly disperse the material and thoroughly remove the mud.
Rotary Scrubber
Crushing Equipment: For rock - type chrome ore, jaw crushers are commonly used for primary crushing to break large - sized chrome ore into smaller pieces. Cone crushers or hammer crushers can be selected for secondary crushing to further reduce the particle size of the ore for subsequent grinding.
Jaw Crusher
Grinding Equipment: Ball mills are the main grinding equipment for chrome ore. They can grind the crushed ore into a suitable particle size to liberate the chrome - containing minerals, facilitating subsequent separation operations.
Separation Equipment
Jig machine: It is a gravity separation equipment suitable for the primary separation of chrome ore. It uses the difference in the settlement speed of minerals with different densities in water to separate chrome ore from gangue.
Spiral Chute: This is an efficient gravity separation equipment. Utilizing the inertial centrifugal force generated by the spiral rotation of the slurry, light and heavy minerals are separated, and this method is widely used in chromium ore beneficiation plants.
Spiral Chute/Spiral Separator
Shaking Table: It is used for the fine - selection of chrome ore, especially for fine - grained chrome ore. Under the action of gravity and horizontal water flow, the material is separated according to density and particle size on the table surface to obtain high - grade chrome concentrate.

Magnetic Separator: Due to the weak magnetism of chromite, magnetic separators, especially high - intensity magnetic separators, are often used to further remove iron - containing impurities in chrome ore, improving the grade of chrome concentrate and the chrome - iron ratio.
Magnetic Separator
Dehydration Equipment: After separation, the chrome concentrate needs to be dehydrated. Commonly used equipment includes spiral dewatering machines and dewatering screens, which can remove most of the moisture in the chrome concentrate to meet the requirements for storage and transportation.
