Introduction of Spiral Chute

The Yufeng spiral chute, spiral concentrator, spiral separator is a mining and beneficiation equipment of collecting the advantage of the all kinds of mining Machinery.It has been used in to classify the granularity 0.3-0.02 millimeters fine grain like iron, tin, tungsten, tantalum-niobium, gold ore, coal mine, monazite, rutile, zircon and other metals. The non-metallic minerals which have a big enough specific gravity difference.

Application of Spiral Chute

1. It is the best separating equipment, especially for separating sand ore in beach, riverside, seashore and stream.
2. metal mines such as iron, tin, tungsten, tantalum-niobium, gold ore, monazite, rutile, zircon and other metals.
3. non-metallic minerals coal mine, coal of coal chemical industry, the sulfur-selection factory
4. scientific research, the design department, the colleges and universities lab.

Working Principle of Spiral Chute

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.
 

Features and Benefits of Spiral Classifier

1. Reasonable structure and small occupation area
2.High recovery, high efficiency, and precise separation,
3.Light in weight, rust and corrosion resistant;
4.Simple installation and Minimal maintenance requirements
5.Low operating cost and long operating life
6.Reliable running with minimal operator attention
7.Strong adaptability to fluctuation of feeding amount, density, size and grade;  

Basic Process of Yufeng ore beneficiation and upgrading plant

1. Crushing and Grinding stage

The extracted ore should be crushed by jaw crusher initially and then by fine crusher. When it gets the reasonable fineness, it is transported into ball mill by elevating conveyer and feeder, and is milled by ball mill.

 2. Classifying stage

The subtle milled ore gets the next procedure: classification. There is a theory that if the weights of solid particles are different, the sedimentations will be different, and the mixed ore can be classified by screw classifier.

3. Mixing and Flotation stage

The classified ore gets into mixing tank for fully mixing. At this stage, chemical agent for foam can be added. After fully mixing, the slurry will enter into flotation machine.

When the flotation machine works, the motor drives the impeller to revolve, so the centrifugal effect and negative pressure are produced. On one hand, ample air is absorbed and mixed with mineral slurry, on the other hand, the mixed mineral slurry is mingled with additive, meanwhile, the foams are thinning, the mineral is bounded with foams, and floats up to the surface of mineral slurry and the mineralized foam is formed. The liquid surface can be adjusted with the height of adjustment flashboard, so that the useful foams are scraped with squeegee.

 4. Concentrator thickening and drying

Then copper concentrate is separated from others. Since the separated ore are wet, they should be dewatered by thicker initially, and dried by dryer.

5. The service before and after the selling:

1).       Ore laboratory test

2).       Ore beneficiation test

3).       Flowchart designing and layout designing.

4).       Full set of machines

5).       Erecting and commissioning

6).       Training

7).       Technical consolation

8).       End products selling
