Slot-shaped ore washing machine is mainly used for washing ore. Its working principle is by agitation action, and with the different relative position of the tooth groove, the ore particles of different sizes and densities displace each other, and the colloid substances and other substances floating on the water are allocated to the orifice of the ore washing machine by the action of the water flow, and the particles are screened, so as to achieve the purpose of washing and grading ore.
The slot-shaped ore washing machine is composed of mainframe, motor, reducer system, mine hopper, water supply, water spray pipe and material separation device. The motor drives the main shaft of the ore washing machine through the elastic coupling and reducer. The main shaft drives the helictite of the ore washing machine. Large-scale ore is taken out of the hopper and enters the first slot. Rotation of the two helicoid tapered spiral tube for different speeds, with the help of the ore particles flow, the ore particles along the feed port and the gap between the two spin rotation of the spiral, are constantly moving towards the other end of the slot, hit, friction and separation between the ore particles is the ore separation process, the effect of the gravel separation from heavier high density, smaller and lower concentration of impurity content of concentrates.
The ore and water sprayed on the ore washing machine were powered by the water pump and then ejected from the nozzle. The shear force that the water jet exerts on the ore particles causes the ore particles to roll and rub against each other, and the gangue particles come out of the gap between the ore particles and the ore particles. The surface of the ore particles is cleaned and the mud layer is peeled off. The heavier particles are discharged from the lower part of the ore washing machine trough and the concentrates with lower content of impurity and higher grade are discharged from the higher side.
Finally, the sediment is discharged from the bottom of the ore washing machine. The adjusted and screened material is discharged from the bottom of the ore washing machine to achieve the purpose of grading and washing, and then the concentrate is recovered.
The slot-shaped ore washing machine has the advantages of low noise, convenient installation and maintenance, no excessive pollution of the surrounding environment, and less wear and tear, making it a more suitable choice for the dressing plant to treat ore. It is mainly used for sorting and classifying of medium and fine particle size minerals, and for cleaning and removing impurities from raw ore.
