1. China YUHONG Gold Mining Equipment/Machine Jigger,Shaking table, Screw Chute Gravity Separation Production Line Introduction

Gravity Separation Process is mainly used for processing sand gold mine, copper slag and chromium ore. Manganese ore, tin ore,Hematite,limonite,fluorite ore, titanium ore, barite, etc.Gravity separation equipment includingconcentrating table ,Spiral chute,jigging machine.

2. China YUHONG Gold Mining Equipment/Machine Jigger,Shaking table, Screw Chute Gravity Separation Production Line Processing Working Principle

Gravity separation process offered by Gude mainly include: crusher machine, vibrating feeder, vibrating screen, gravity separation equipment, conveyor belt, etc. In gravity separation process, has the following working process:

1. When gravity separation process works, it uses the action of the water to disperse the mud agglomeration or fine mud bonded to quartz particles, and then removes it.This process is used in glass, foundry and other industries.

2. According to the different size, mineral has different dropping velocity in water flow. In general, the mineral size is divided into several levels. The gravity separation process distinguishes different grain size to meet user requirements, it is suitable for processing foundry sand, glass sand, cement and standard sand.

3. The iron ore particles with high density will drop rapidly in the water and quartz particles which are influenced by horizontal and vertical flow are separated from heavy minerals. The gravity separation process is applied to glass sand to remove iron and other heavy minerals.

Gravity separation usually jig beneficiation, beneficiation chute, shaking beneficiation (out tray) and heavy media beneficiation; according to the media used, and the re-election of wet and wind re-election (dry).

Treatment with the re-election of mineral raw materials, generally the first material with a screening or hydraulic classification method is divided into several levels according to size, and then treated with a suitable level of granularity of the material re-election equipment selection, composition grading process selected processes. Coal is often not graded but will coal directly selected.

Jigger Jigging

Using vertical alternating currents so that the material loose, to another according to the proportion stratification and selection process. Jig is a fundamental part of jigging chamber, chamber built sieve. A mixture of water and mineral particles from one end to the entry of the sieve jigging chamber, mineral particles in alternating vertical movement under the action of water, alternating loose and tight, and finally stratified according to their difference in specific gravity. A small proportion of products with the pulp in the upper stream from the upper discharge; than the major products in the lower by the lower discharge. Jig wide range of mineral jigging machine with reciprocating motion of the diaphragm caused by the flow of alternating movement, and create favorable layered zigzag motion curve.

Jigger's main operating parameters of the water flow flushes, stroke, undersize water recharge, feeding capacity and feed concentration and the proportion of bed rock, particle size and thickness. Jigger processing capacity per unit area, the device structure is simple, easy operation and maintenance. With the expansion of the scale beneficiation, jigger into large scale.

Shaking Table Tabling

Shaker with a bed or the groove by the transverse tilt bed surface and transfer mechanism . Transmission mechanism for the bed surface longitudinally asymmetric reciprocating motion. The mineral particles in the bed surface mechanical vibration , lateral flow and bed of slurry between the combined effects of vortex loose segregations , layered , sub- band . A small proportion of the upper mineral particles , large size , lower than the major mineral particles , particle size is small , the upper slurry flow speed , lateral movement of mineral particles and therefore also faster ; lower slurry flow rate is small, due to which mineral particles and the bed friction force by mechanical handling large , large vertical moving speed ; different size and specific gravity of the mineral particles in the bed surface so as the separation of different trajectories .

Shaker main structural parameters of the motion characteristics of the transmission mechanism , the bed and the bed of the shape, size and arrangement . Main operating parameters of the bed surface is red times , stroke , horizontal angle, rinse water , to the ore and the ore concentration. Typically, the ore with a small fine stroke, high pumping speed and low bed strip ; otherwise using a large stroke and low times and high beds amended. Shaker sorting efficiency, especially enrichment ratio , we have a variety of products ; processing unit area , but a small amount of equipment .

Screw chute launder
With water flowing in an inclined slot for material selection process else. Mineral particles in gravity, friction, water flow pressure, shear force and retaining strip resistance (groove surface of a block of time) and other joint action, loose, layered, reached by gravity separation. According to the granularity of materials handling divided into: 1. coarse chute (feed size is usually 2 ~ 3mm, up to 100mm or more) with fixed and belt for sorting gold, tin and tungsten ore sand, etc.; 2. ore chute (feed size 2 ~ 0.074mm)

Pulp from the top to the entry . Rotational flow around the central axis from top to bottom . Mineral particles in gravity flow momentum , centrifugal force , friction, and along the inner ring into the rinse water to the combined effects of their movement along different trajectories , heavy mineral particles turning around in circles ; proportion of small mineral particles then enter the outer ring . Pick out separately in different locations , you can get different products . Spiral concentrator more transverse cross-sectional form of the ellipse 1/4 , 2 ~ 0.07mm for sorting ore particles ; spiral chute cubic parabola -shaped cross-section , suitable for sorting ore particles of 0.3 ~ 0.02mm . Spiral chute spiral concentrator and infrastructure investment , low energy consumption , the device is simple and reliable , easy operation, enrichment is high, you can get a variety of products . But it must be uniform to the mine.

Centrifugal election

Strengthen the use of centrifugal force, according to the proportion of other election process, in 1964 China Yunnan Tin Company created a centrifugal concentrator, do 74 ~ 10μm optional mineral particles per unit area processing capacity of 0.8t / (m² · h), has been widely used in Chinese tin, tungsten and hematite ore sorting. More for roughing.

For a more efficient recovery of gold ore crude grains of gold, were re-elected Nelson concentrator test. Test samples were taken from the chute and the re-election of tailings cyclone grit. According to Nielsen concentrator selected size requirements, chute tailings re-election to +4 mm sieve size portion,-4mm grain to Runiersen machine re-election; cyclone grit directly selected. Nelson concentrator only for coarse grain and the recovery of gold has a good capacity, but of fine gold (0.01 ~ 0.04mm) can be effectively recovered, and subsequent cyanidation can be considerably shortened.
