HPC-10 Photos
HPC-10_010
The HPC-10 is a complete and fully mobile recovery system offering unbeatable capability for recovery of gold, gemstones and other minerals.
HPC-10_020
The mobility and capacity of the HPC-10 make the machine ideal for exploration, bulk sampling, startup and artisanal mining operations.
HPC-10_030
The HPC-10 is fitted with a Manual Feed Chute, for feeding of dry, moist or wet material as well as slurry, mud and clay-containing materials. Material is loaded onto the Chute and manually pushed into the Scrubbing Trommel.
HPC-10_040
Robust construction, simple operation and compact design make the HPC-10 an ideal machine for remote, hard-to-reach locations.
HPC-10_050
The HPC-10 is extremely versatile and ideally suited to exploration projects tasked with establishing the viability of a wide range of mineral recovery projects.
HPC-10_060
The Scrubbing & Screening Trommel installed in the HPC-10 facilitates simple and effective washing and classifying of a broad range of materials.
HPC-10_070
The trailer-mounted HPC-10 is completely mobile. The machine can easily be towed by a small pickup truck (total weight is approximately 1.8 tons).
HPC-10_080
Water supply to the HPC-15 is fed into the Water Manifold. The Water Manifold allows independent control of water flow throughout the HPC-15. Extra outlet valves are included for a general purpose hose and for any auxiliary equipment that requires water.
HPC-10_090
Material from the Feeder is washed into the high-rpm Trommel where it is thoroughly scrubbed and screened.
HPC-10_100
The Trommel is supported on two sets of heavy-duty casters. Caster brackets are designed to allow for easy maintenance.
HPC-10_110
The Trommel Scrubber is divided into 2 sections, each with 3 lifting paddles. Material washed into the Trommel is retained in each section to allow thorough tumbling and washing of rocks, gravel, sand and clay before screening.
HPC-10_120
Scrubbed material passes from the Trommel Scrubber section to the Trommel Screen. Fine / undersize material falls through the screen whilst large / oversize gravel and rocks are retained and fed to the Discharge Section of the Trommel. Lifters inside the Trommel Screen and additional water sprayed into the screen ensure that all fine particles are discharged through the screen.
HPC-10_130
The Trommel Screen is bolted into the Trommel and can be removed and replaced if required. This allows for easy installation of different screen sizes if needed.
HPC-10_140
Oversize material is fed from the Trommel Screen to the Discharge Section where it is discharged from the machine. The water nozzle at the rear of the Trommel sprays water into the Screening Section of the Trommel to assist with the washing process. The Discharge Section is also fitted with a Nugget Trap to retain nuggets which have not passed through the Trommel Screen.
HPC-10_150
Oversize material discharged from the Trommel falls onto the Oversize Chute. These rocks and gravel form a pile at the back of the machine which must be cleaned up as required.
HPC-10_160
Fine / undersize material washes through the Trommel Screen, falls into the Material Distribution Chute and is then washed onto the Concentrator Belt. The Chute can be adjusted to precisely control where material is discharged onto the Concentrator Belt. This allows for additional control of mineral recovery and yield in certain applications.
HPC-10_170
The reverse spiral Concentrator Belt is a unique feature of the EXTRAC-TEC HPC Technology. The Concentrator Belt enables complete control of the fluidization of material with long retention time for unbeatable recovery of heavy particles by gravity separation (see videos for a detailed presentation ).
HPC-10_180
Additional control of material fluidization on the Concentrator Belt is achieved through the Vibration Roller and Belt Washbar. Vibration of the Concentrator Belt assists with settling of heavy particles whilst independent control of water flow onto the Concentrator Belt ensures correct control of material fluidization (slurry / pulp density).
HPC-10_190
The Concentrator Belt separates heavy and light particles. Heavy particles are then washed onto the Concentrate Sluice. Rotation and Inclination of the Concentrate Sluice can be adjusted for optimum recovery of heavy particles.
HPC-10_200
The Concentrate Sluice has 4 recovery sections, each containing a Concentrate Mat, Riffles and a Riffle Lock. During periodic cleanups, Concentrate Mats are taken out of the sluice to remove heavy concentrate.
HPC-10_210
Light particles are washed off the Concentrator Belt onto the Tail Sluice. Analysis of heavy particle recovery in the Tail Sluice is used to provide feedback on whether the machine setup is correct / optimal or not.
HPC-10_220
Brackets are provided on top of the HPC-10 to attach the Concentrate Sluice when towing the machine.
HPC-10_230
A heavy-duty electric motor and gearbox drive the Concentrator Belt and Trommel.
HPC-10_240
The drive motor and gearbox are mounted on an adjustable bracket and located behind safety a safety cage.
HPC-10_250
Tensioning bolts on the Drive System mounting bracket allow for easy tension adjustment of the drive chains.
HPC-10_260
An electrical controller – housed inside a water and dust-proof control box – enables precise speed control of the Trommel and Concentrator Belt. After initial setup, the Control Box can be locked – only the On/Off switches are required for day-to-day operation.
HPC-10_270
Heavy-duty bearings are used throughout the HPC-15. Maintenance involves regular lubrication only.
HPC-10_280
The Belt Washbar is fitted with a purge valve to allow for easy flushing of dirt from the water circuit.
HPC-10_290
Tensioning bolts for adjustment of roller positioning and Concentrator Belt profile.
HPC-10_300
Tensioning bolts for adjustment of roller positioning and Concentrator Belt profile.
HPC-10_310
The 2 storage areas at the front of the HPC-15 Trailer offer room for storage and transportation of your extra equipment and supplies.
HPC-10_320
A water pump, generator, tools, fuel and other auxiliary equipment can easily be secured and transported on the Trailer.
HPC-10_330
The Jockey Wheel at the front of the Trailer is not only useful for hitching the HPC-15 to a vehicle – it is also used to easily adjust the inclination of the entire machine during set-up.
HPC-10_340
The machine is fitted with 4 Landing Legs. These are locked in place once the HPC-15 is set-up so that the entire machine is stable and secure.
HPC-10_350
The HPC-15 Trailer is fitted with an adjustable Tow Hitch bracket which allows different hitches to be used – Pintle Hitch fitting installed in this image.
HPC-10_360
The HPC-15 Trailer is fitted with an adjustable Tow Hitch bracket which allows different hitches to be used – Ball Hitch fitting installed in this image.
HPC-10_370
International shipping of HPC-10 machines is easy – the machine is transported in a 20′ container with plenty of room for additional equipment such as a water pump and electrical generator.
