The HPC-30 Heavy Particle Concentrator is one of the most advanced gravity recovery systems available and is the ideal solution for small-scale and start-up mining operations.
HPC-30_020
The HPC-30 is suitable for a broad range of heavy particle concentration applications and is capable of processing up to 30 tons per hour, depending on the gravel composition. Refer to specifications sheet for more information.

The HPC-30 recovery unit is offered with a choice of feed systems to accommodate a broad range of applications, sites and operating conditions. The AF-30 (artisanal feeder) shown here, is a simplified Feed Conveyor without a Hopper/Grizzly, designed for manual feeding of the HPC-30 in Artisanal and Small-Scale Mining Operations.
HPC-30_080
The HPC-30 recovery unit is offered with a choice of feed systems to accommodate a broad range of applications, sites and operating conditions. The FC-30 (mobile feed conveyor) shown here, is a Feed Conveyor with Hopper and Grizzly, designed for use with the HPC-30 with material that is not sticky and has low clay content. It can be fed with an excavator, backhoe or small loader.
HPC-30_090
The HPC-30 Feed Chute is designed to receive -150mm material from a conveyor and feed it into the scrubbing section of the Trommel.
HPC-30_100
The angled design of the Feed Chute accommodates a variety of feed rates and material types.
HPC-30_110
The Feed Chute’s independently controlled water inlet washes material into the Trommel and provides water for scrubbing.
HPC-30_120
The high-rpm Scrubbing / Screening Trommel thoroughly washes and screens material so that undersize/valuable fraction is processed whilst oversize waste is rejected as tailings.
HPC-30_130
Trommel speed and inclination are adjustable to ensure maximum effectiveness and efficiency.
HPC-30_140_
The Trommel can be lifted and lowered for optimal position and access during operation, maintenance and transportation.
HPC-30_150
The Trommel scrubber has 3 chambers to maximise scrubbing retention time and material lifters for aggressive material washing action.
HPC-30_160
The Trommel screen classifies material so that smaller, mineral-rich particles are processed whilst oversize waste is rejected.
HPC-30_170
The screening section comes standard with a 6mm (1/4″) screen and can be customized for specific applications as needed. The modular design allows for easy screen replacement should the screen get worn or if a specific screen size is required.
HPC-30_180
The screen lifters agitate the material for thorough rinsing and classification.
HPC-30_190
Two spray nozzles are independently directed to maximize rinsing of material in the screening section.
HPC-30_200
Four sets of heavy duty casters ensure adequate support plus smooth rotation and tracking of the Trommel at low and high rotational speeds.
HPC-30_220
The Trommel Drive System components comprise of robust internationally recognized brands. The Gearbox position is easily adjustable to maintain proper chain tension at all times. Trommel speed is independently controlled by a dedicated Variable Speed Drive.
HPC-30_240
The Trommel inclination can be adjusted for process optimization – typically flatter for materials requiring longer retention time in scrubbing/screening sections.
HPC-30_250
The Trommel is easily lifted with a 4-ton hydraulic jack which is included in the machine’s spares kit. This easy, low-tech solution requires minimal equipment.
HPC-30_260_
Once the correct Trommel position and inclination are found, the Trommel can be pinned in place.
HPC-30_280
The Oversize Chute directs oversize tailings discharged from the Trommel away from the back of the machine so that these can easily be removed for disposal.
HPC-30_290
Our internationally patented reverse-helix Concentrator Belt ensures unbeatable recovery of liberated gold and heavy particles, eliminating the need for any chemicals or mercury.
HPC-30_300
We offer a variety of Concentrator Belt designs for different applications.
HPC-30_310
The Concentrate Sluice features 4 recovery sections optimized to provide ultra-high concentration ratios with an unbeatable recovery rate.
HPC-30_320
Each recovery section consists of riffles, riffle locks and concentrate retention mats.
HPC-30_330_
The first part of the Concentrate Sluice is a stilling section which smooths material flow into the recovery sections. Water flow to the sluice is independently controlled.
HPC-30_340_
Sluice inclination and angle of rotation are easily adjusted to suit processing conditions.
HPC-30_350
The Tail Sluice serves as a very useful process calibration tool, especially during initial setup. Regular checks quickly indicate incorrect feed rate, machine inclination, water flow rate and other settings.
HPC-30_360
The Tail Sluice consists of riffles, riffle locks and retention mats and is removable for easy storage during transportation.
HPC-30_370
The Independent Belt Drive System components comprise of robust internationally recognized brands. The Gearbox position is easily adjustable to maintain proper chain tension at all times. Speed is controlled by a dedicated Variable Speed Drive.
HPC-30_380
The vibration roller agitates material on the Concentrator Belt which further aids the settling and recovery of heavy particles.
HPC-30_400
The main Washbar helps fluidize material and keeps the belt clean. The nozzles are independently controlled and can easily be adjusted to customize flow rate depending on desired material pulp density.
HPC-30_410
Tensioning bracket for adjustment and locking of rollers.
HPC-30_420
High quality flange bearings are used to secure the rollers to the HPC-30 frame. The bearings are easy to maintain and are readily available should they require replacement.
HPC-30_430
Easily removable Safety Cages at the front of the HPC-30 offer protection from moving parts during operation.
HPC-30_450
The removable Pintle Hitch and safety chain allows the HPC-30 to be connected to almost any type of towing vehicle.
HPC-30_460
Two sets of heavy-duty axles and wheels are installed for transportation and mobility on site. These can easily be removed and stored, once the landing legs are in place.
HPC-30_470
Four adjustable, heavy-duty landing legs stabalize the unit once on site.
HPC-30_480
A storage area is provided for cables and hoses as well as accessories.
HPC-30_490
All electrical controls are housed inside a dust and waterproof control box.
HPC-30_500
Once the electrical controls have been set, the box can be locked as the operator only needs to access the externally mounted on/off switches for the Feeder, Trommel and Concentrator Belt.
HPC-30_510
An auxiliary control box for the AF-30 or FC-30 Feeder can also be mounted on the HPC-30.
HPC-30_520
Water Control Manifold with valves for independent control of water flow to each section of the machine.
HPC-30_530
Mobility means easy placement on site which allows for quick setup and commissioning. It is extremely easy to move these units around on-site and closer to stockpiles to minimize material handling costs.
HPC-30_540
The HPC-30 is an extremely versatile concentrator which can be used in a broad range of mineral exploration activities, configurations and production applications.
HPC-30_550
Our equipment is made from high quality components which will withstand the most extreme conditions. Equally our robust design has made it possible for units to run non-stop 24/7 to optimize production
HPC-30_560
HPC machines can be fed with re-circulated water provided the water is free of larger suspended particles which block smaller water nozzles. A series of settling ponds is a simple way of implementing a water recirculation circuit.
HPC-30_570
Customized HPC-30 machines are available for pre-concentration applications where material is pre-classified and the scrubbing/screening trommel and sluices are not required.
HPC-30_580
Transportation of the equipment is effortless due to mobility of machines which can be loaded and offloaded with a normal loading ramp.
HPC-30_590
The HPC-30 fits into a 20′ Container for shipping. It can be shipped with the AF-30 feeder in a 20′ container or in a 40′ container with a FC-30 feeder. Equipment can be loaded and offloaded from the container with a normal pick-up truck. Containers can be purchased for use as a storage facility on-site.
