Description:
Spiral chute is a high efficiency gravity concentrator of the international advanced standard. It is the newly re-selecting equipment. It is the best equipment for a mining and beneficiation, especially the placer mining of waterfront, river, sand beach, creek road is more ideal.
Structure:
Spiral chute is made up of feeder, feed chute, spiral flute, bracket, intercepting slot, and supporting frame, etc.
Application:
This device is suitable for sorting size 0.3 - 0.02 mm thin material of iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, phosphorus B ore, tungsten ore, tin, tantalum ore, niobium ore as well as the proportion of differences and other nonferrous metals, rare metals and non-metallic mineral body.
Features:
1. Sorting process is stable, easy to control.
2. Big ore concentration allowable variation range.
3. Enrichment ratio, high recovery rate.
4. Small area, less water consumption.
5. Simple structure, without power, large capacity.
6. Easy to install, easy to operate, small investment.
Working principle:
Make the screw chute stand, adjust the vertical line, fixed the proper place with the iron structure or wood, make the ore sand deliver to two feed openings of the screw chute top, enter enough water, adjust the mash chrome, the mash flows freely from the high, produce the intertial force at the speed of the rotary, divided the sand and ore, the concentrate comes into bucket with the tract, gangue comes into the bucket with the tract to the sand pool, and pump off, complete the whole process.
