MechChem Africa’s Peter Middleton visits Sasol’s wax packaging plant to find out about its use of SEW-Eurodrive’s MOVITRANS® contactless energy transfer solution to manage the transfer of loaded pallets from its robot packing cell.

SEW Sasol Wax Plant MOVITRANSSasol Wax and Solvents is a leading global producer of a comprehensive range of mineral oil-based and synthetic paraffin waxes, petroleum jellies and liquid paraffins, the company’s GTL process making Sasol’s waxes unique to the market.

Sasol’s waxes are derived from sustainable feedstock, ie, natural gas, and offer superior performance in a variety of applications thanks to a combination of high melting points, low viscosity and excellent hardness, even at elevated temperatures.

Sasol exports to more than 200 countries for a wide variety of applications: adhesives; bitumen modification; construction board; cosmetics and pharmaceuticals; industrial applications; packaging; and polymer processing, rubber and tyres. Candles are also a major market for its waxes, while some co-products are used in products as diverse as bore hole- drilling fluids/muds.

In the cosmetic and pharmaceutical industry waxes are used as softeners in lotions and creams such as cleansing milk, lipid-replenishing cosmetics and sun protection agents. They are also used as the base for creams, lipsticks, rouge and eye cosmetics such as eyeshadow, eyebrow pencils and mascara.
Other applications range from shaving foam, hot and cold depilatory waxes to thermal therapy, which exploits the outstanding heat storing properties of synthetic paraffin waxes.

Wax packaging

“Sasol offers a massive range of hard and medium waxes, all with different product codes, colours, hardness and other special properties. As soon as a pallet is fully loaded with the correct wax, it is rolled down its conveyor towards the aligned transfer trolley. Once on the transfer trolley, the pallet is moved across to align with the exit conveyor, which then takes the pallet out of the cell to the pallet-wrapping machine.

MOVITRANS replaces the chain

The two transverse trolleys, each servicing conveyor lines from one of the packing robots, used to be powered via drag chains in the centre of the rails. The transverse pallet trolleys each have two motors, one to drive the conveyor rollers and another to move the trolley along the rails. These were powered via a drag chain that carried the power and communication cables.

According to Sasol, this was problematic. Wax would clog the chain links, impeding its free movement; operators would have to step into the cell to align the trolleys properly, often standing on the chain; and the chain would break causing production stoppages for repair or replacements. In addition, this ...
