Small Scale Gold Mining Equipment

Four kinds of gold processing equipment performance analysis

1.About spiral classifier

Spiral classifier by means of solid particles of different sizes, different specific gravity, thus settling velocity different principles in liquids, fine mineral particles floating in the water to overflow the coarse mineral particles sink to the bottom. Discharged by the screw into the upper part, to a hierarchical classification of mechanical equipment, the mill can grind material powder level in the filter, and then use the coarse material piece rotary vane screwed spiral mill feed inlet, the filter out the fine material discharged from the overflow tube. The machine uses the base channel, the body uses welded steel. Into the head of the screw shaft, the shaft head, using cast iron sleeve, wear-resistant and durable, lifting devices of electric and manual.

2.Ball Mill Introduction

The ball mill is a horizontal cylinder rotating device, outer gear, the two positions, lattice-type ball mill. Material from the feed device evenly into the mill first position into the compound empty-axis spiral, the warehouse has ladder liner or corrugated liner, built with different specifications steel ball, rotating cylinder produces centrifugal force to the ball a certain height after the fall, have severe impact on the material and abrasive. Material in the first position kibble, after single-compartment plate into the second warehouse, the warehouse lined with flat lining, the steel ball, the material to further grinding. Powder through the discharge grate plate to complete the grinding operation. Small Scale Gold Mining Equipment.

The machine consists of feeding part, discharging part, turning part and driving part (reducer, small transmission gear, motors, electrical control) and other major components. Hollow shaft with steel, lined with removable, rotary gear hobbing by casting, the body inlaid cylinder liner wear, has good abrasion resistance. The machine running smoothly, reliable work.

3.Wet magnetic separator Profile

Wet Permanent Magnetic Drum Separator is a magnetic separator iron ore dressing plant common use , it is suitable for sorting ferromagnetic minerals . According to different structural types of tank , separator into downstream , counter , semi- countercurrent three. Three different body style slot selected particle separator as follows : downstream tank ≤ 6mm, countercurrent tank ≤ 1.5mm, half countercurrent tank ≤ 0.5mm.


Magnetic separator downstream processing capacity, suitable for processing coarse grained ferromagnetic materials roughing and also more than one series of work . When downstream magnetic separator to mine large , the magnetic mineral particles easily lost in the tailings , so to enhance the operational management and control of the lower pulp levels.Small Scale Gold Mining Equipment.


Countercurrent separator suitable for fine-grained ferromagnetic minerals rougher and scavenger operations, higher recovery rates , but lower concentrate grade . Because the deposition of coarse material is easy to plug sorting space, so counterflow magnetic separator suitable for handling coarse materials.


Semi- countercurrent separator can obtain high-quality iron ore, but also can get a better recovery rate, so half countercurrent separator is widely used in the production practice . It is suitable for processing 0.5mm below roughing and selected mineral particles , but also can be more than one series and parallel to achieve multiple sweep selection and selection .

4.Jaw crusher Introduction

Working part of jaw crusher jaw is two , one is fixed jaw plate ( fixed jaw ) , vertical ( or slightly upper camber ) fixed in the front wall of the body , and the other is movable jaw plate ( moving jaw ) , location inclined to form the next big small crushing chamber ( working chamber ) and the fixed jaw . Movable jaw against the fixed jaw do periodic reciprocating motion , sometimes separately , sometimes close . When separated material into the crushing chamber from the lower finished unloading ; close, so mounted between two materials being squeezed jaw , bending and splitting the role of fragmentation . Which has the following characteristics : a simple structure, easy maintenance ; stable performance, low operating costs ; crushing ratio, uniform particle size of the product ; 2 crushing chamber depth and no dead zone , improving the feeding capacity and output ; discharge port . adjustment range, can meet different user requirements ; 3 gasketed discharge opening adjustment device , reliable and convenient , adjustment range, increase the flexibility of the device ; 4 lubrication system is safe and reliable , easy parts replacement , small maintenance workload ; ; 5 energy-saving equipment : stand-alone energy-saving 15% to 30% , saving more than double ; through continuous efforts of many mineral processing workers , domestic mineral beneficiation process equipment and technology content have been greatly improved, as industrial production provide a good starting material .
