In the sluice box we input water, sands, silts, and gravels, now the water is what is used to transport the materials from one end of the sluice to the other and in the process gravity and specific gravity allow for the heavier minerals to settle towards the bottom of the sluice and the lighter materials are catch up in the water as a suspended load. Now this works to a degree and it doesn¡¡¥t, as the bed load materials can and will be caught up by the water flow and moved along and right off the end of the sluice. To trap and hold the heavy minerals in the sluice we need some obstructions in place, this is where the riffles and matting come into play, and the matting while having importance in gold recovery, is not as relevant in the recovery of gold as the riffles. The riffles now these are important and having the right design of riffles will make an enormous difference in the amount of gold that you are able to recover from a cubic metre, therefore the amount of material that one will have to excavate and wash through you sluicing system when working. So having the right type of riffle system for the type of sluice box operation you want to use is going to make your gold recovery more efficient and cost effective, therefore more gold in your pocket at the end of the day.
Featuring low cost, high efficiency, small space occupation, energy conservation, sturdy and durable structure, maintenance easiness and high return on investment, this NJ wet pan mill of pioneers is mainly used for concentration of gold, silver, lead, zinc, molybdenum, ferrum, copper, antimony, tungsten and tin etc. This pioneers pan mill is the first choice of substitute for ball grinding machine and is the ideal choice for medium and small-sized mineral separation enterprises. Wet pan mill of pioneers is modified based on traditional machine. Due to the large size of work piece, short operation period, high-power motor and long installation period, it is impossible for users to put traditional machines into operation immediately, and the maintenance and replacement of material requires large hoisting equipment.
Rock Hammer crusher also called Hitting Granulated Substance Machine, which can crush ore which is below 50mm or the tailings, middlings which in the uncompleted ore.

Beneficiation spiral chute integrates features of spiral concentrator, shaking table, and centrifugal separator. It the best equipment for mineral processing, especially used for mining sands in coastal, river, sand beach, river road, etc. Beneficiation spiral chute is adapted to process alluvial deposit, especially flat materials with high monomer dissociation degree of useful minerals. Besides, since minerals containing high mud have low concentrate quality, so they must be de-slimed and graded before entering into the beneficiation spiral chute. The working features of beneficiation spiral chute is that the concentrate, middling and tailings are gotten at the end of the equipment, and the sorting process does not need washing water. Spiral chute is the main component of the device, which is made of polyurethane wear-resistant plastic or mixed artificial corundum resin. Its liner is made of FRP a wear-resistant material. On the top end of beneficiation spiral chute, there is a mineral separation device and a feed tray; at the lower part of beneficiation spiral chute, there is a products interceptor and a trough for receiving ores. The whole equipment by pioneers manufacturer stands vertically though still frame.
JT series Saw-tooth Wave Jig is a new type of energy saving and high efficient gravity separation equipment and developed based on the traditional Sine Wave Jig. The difference between Saw-tooth Wave Jig and Sine Wave Jig is that the pulsation curve for jigging is saw-tooth wave shape, with speedy upward flow and slow downward flow. Bed layer is elevated integrally and slowly dropped with a long effective loose time, allowing significant increase of handling capacity for unit screen surface, decrease of lower limit of grain size recovery and large save of make-up water for under size fraction. In practice, contrast of Saw-tooth Wave Jig and Sine Wave Jig shows up raises of recovery of Saw-tooth Wave Jig: Sn:3.01%, W:5.5%, Pb:1.63%, Zn:2.04%.Shicheng Pioneers Mining Machinery Manufacturer Factory has strong technical advantage and production power on rougher jig machines production, and wins customers¡¡¥ support and trust deeply.
Centrifugal gold concentrator is a relatively new type of gravity concentration apparatus. The machines of pioneer s stlb series concentrator utilise the principles of a centrifuge to enhance the gravitational force experienced by feed particles to effect separation based on particle density. The key components of the unit are a cone shaped "concentrate" bowl, rotated at high speed by an electric motor and a pressurized water jacket encompassing the bowl. Feed material,typically from a ball mill discharge or cyclone underflow bleed, is fed as a slurry toward the centre of the bowl from above.The feed slurry contacts the base plate of the vessel and due to its rotation, is thrust outward.The outer extremities of the concentrate bowl house a series of ribs and between each pair of ribs is a groove. During operation the lighter material flows upward over the grooves and heavy mineral particles (usually of economic value) become trapped within them. Pressurized water is injected through a series of tangential water inlets along the perimeter of each groove to maintain a fluidized bed of particles in which heavy mineral particles can be efficiently concentrated. Centrifugal gold concentrator is an efficient equipment for recovering free gold in all particle size ranges,specially for recovery of fine gold which is lost during the operation of the gravitational concentrators(sluice boxes and jigs). It can be used not only for placer gold mining, but also for recover the natural gold from hard rocks, to replace amalgamation, and recover gold from the tailings.
