The rotary scrubber is an autogenous rotating drum scrubber, utilizing pebbles and rocks within the feed source to fracture and disintegrate clays, agglomerates and soft oxides. The scrubber spins slowly, similar to a giant washing machine. It churns the fines and oversize and water together, vigorously breaking up the soil matrix as well as liberating the target mineral from tough clay, schistand rock. Disintegrated material is homogeneously slurried within the drum, whilst the autogenously load is retained within the drum by reverse flights located at the drum discharge end. Slurry and washed oversize overflows the drum discharge throat to the concentric exit trommels. This material is then passed on to the downstream process equipment in pioneers machinery which can be in various forms such as centrifugal concentrator, spiral chute, rougher jig etc.

Tray Type Centrifugal Gold Separation Machine LP600 also called gold panning machine in pioneers machinery factory as heavy medium separation appliance, is supported with hollow shaft and driven by power, with its major part being of cauldron disk. Slurry is transferred via slurry pump to the separation disk center where ore grains are acted by both gravity and inertial centrifuging force. During the course of movement by the ore grains upwards along the center of disk surface, when angle is greater than 45 degrees, the centrifugal component force in the direction of slope will gradually decrease while gravity component force will gradually increase. When it is up to a certain level, the two forces will reach balance, and near the point of balance easily develops a heavy mineral sediment layer. Tailings are discharged from edge at the upper disk, and concentrates after stop of feeding ( shut-down), are washed with water before being drained by hollow shaft. The major structure of the machine follows the technical data about gold washing from KNUDSEN, Australian mining company. The machine is primarily applied for washing and separating placer gold at a size of minus 4mm and is capable of recovering natural gold grains at sizes of over 15 um. In operation, inner hole of the center is blocked using plug with its drainage and collection at a regular basis. It can be operated intermittently or continuously, with the ore feeding and water adding simultaneously. The rotation direction is anti-clock( as indicated by arrow) at a speed of 70-110 r/pm. Ratio between solid and liquid for slurry is 1/4-2/3. The machine can be operated by power individually and multi-machines also can be operational in a combined or pedal manner ( without power supply ).
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.

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.
