How Spiral Chute Separator Works

How Spiral Chute Separator Works

Zhengzhou, China (prHWY.com) June 7, 2012 - Mobile crushing and screening plant is the popular stone crushing and recycling equipment in modern world. Mobile crushing plant, so-called portable crusher, mobile crushing and screening plant, usually contains track mounted mobile crushing plant (crawler type mobile crusher), semi-mobile crushing plant (trailer mobile crusher), and spiral chute separator.

General Idea of Spiral Chute

Spiral Chute manufactured by our company is suitable for sorting for gold mine, silver mine, alluvial gold mine, lead-zinc mine, copper mine, tin mine, titanium iron mine, pyrite mine, hematite, etc. It is high efficient equipment for sorting ferrous, nonferrous, nonmetallic mine and minor metal mine. The product is composed of the chlorine plastic with the advantage of simple structure, light weight, lower power consumption, easy operation, reliable operation, easy maintenance, smaller area, high capacity, and high separating efficiency.

Gravity Spiral Chute Usages

The Spiral Chute is used to process iron, sternum, tungsten, tantalum, niobium, gold ore, colliery, monazite, rutile and zircon of sizes between 0.3 and 0.02 mm. The Spiral Chute is comprised of a feeder, feed chute, spiral flute, bracket, intercepting slot and supporting frame. It is compact, light weight, reliable easy to operate and maintain, efficient, and has a high capacity. We also provide spiral classifier.

To research the coal wash-ability, operators need to expand test for fine granularity. The aim of test is to make an exact prediction on the separation efficiency of coal, which is just like the evaluation on the floatability. The granularity size for the test should be divided into five grades, which are 3-1.68mm, 1.68-1.00mm, 1.00-0.59mm, 0.59-0.15mm, and 0.15-0.074mm respectively. The ratio of these float-and-sink tests is 1.3~ 2.2, and the disparity ratio is o.10. mobile crushers:http://www.hxjqchina.com/product-list_21.html

Working Principles of Spiral Chute

It mainly uses water as the conveying medium. Water in the spiral chute runs downward spiral movement and also flows in circulation transversely. Water in the upper layer run fast, generating centrifugal force with large inertia to toss toward the outer edge of the chute. Back-flow of water in the lower layer adjacent to the chute bottom runs slowly with small centrifugal force and flows from the outer edge to the inner edge with the action of gravity, generating secondary back-flow. Particles of heavy minerals in slurry settle rapidly and gradually move toward the inner edge along the converged helix prior to finally being produced as concentrate. Light minerals settle slowly and flow fast in the surface layer of ore flow with large centrifugal force and gradually move toward the outer edge along the expanding helix before finally being produced as tailings.

Features and Advantages of Construction Chute

Steady separating process; Easy to control; Large allowable change range of feed ore concentration; High enrichment ratio; High recovery ratio; Small ground occupation; Small water consumption; Simple structure; Without motor; Large capacity; Simple installationï¼›Easy for operation; Low investment

As the professional manufacturer of complete sets of mining machinery, such as vibrating grizzly feeder, Henan Hongxing is always doing the best in products and service.
