Conveying Systems
Conveyor Systems
The Spiral Conveyors are designed for the transportation of difficult to handle materials, either shafted or shaftless. It can be used for conveying of wet or dry products such as coal, municipal sludge, screenings, grit, industrial sludges as well as wood chips, steel shavings and other mining and general products. The Spiral Conveyors uses low RPM which results in virtually a maintenance free unit with a long-life expectancy. The enclosed conveyor designs will ensure that the environment is safe from spillage, hazardous materials and odours are contained.
The Spiral Conveyors are tailored to the customer’s need and only constructed with the best quality materials. The spirals are designed in carbon steel/304SS/316SS up to a thickness of 35mm.
Two types of troughs are designed to fulfil the customers unique requirements. The U-Trough are suitable for horizontal conveying and at an incline up to 45º and has a high capacity up to 90m³/hr. The O-Trough are suitable for vertical conveying most materials at an incline up to 70º and up to 90º when force fed with a high capacity of 50m³/hr.

Screw Pumps
The invention of the screw pump comes from ancient periods when the technology was used for overcoming water transport elevation in the form of the Archimedes screw.
The screw transports the waste water from the bottom of the screw pump inlet to the exit of the pump. The screw is effective in pumping water filled with waste and debris with the least maintenance and highest effectiveness.
When an impeller pump is used to raise the water, it is necessary to install a screen ahead of the pump for the purpose of removing particles that can damage, block or cause excessive wear to the pump.
The installation of an upstream fine screen creates high civil construction costs difficulties transporting the screenings up to ground level and a hazardous confined space area. The Screw Pumps are capable of transporting sizable items within the water and lengths of light timber are broken up by the reinforced leading edge of the screw flights. Installing a screw pump in this application, relocates the screen above ground level and saves significant civil construction costs.
In a low lift, high-capacity waste water application, an efficiency of 80% can be realized using a screw pump. During a 24hr flow pattern of influent, the amount of waste water can range between 30% – 100% of the design capacity. Coincidentally, one characteristic of a screw pump is the ability to maintain a high efficiency rating over the same range of flow capacities.
The Screw Pump is designed with diameters up to 3000mm and lengths up to 20 000mm for various areas of applications:
- Inlet and final effluent pumping of waste water treatment plants (WWTP),
- Inter-stage pumping of WWTP,
- And the return and surplus sludge pumping in WWTP.
When retrofitted with a generator unit and installed in a river or low-level dam, these pumps can function as hydro-electric power generation units. They can handle debris and sludge to quite a large extent.
