New “drop test” benefits rotary breaker customers

A new service offering called a “Drop Test” has recently been launched by Osborn to ensure that rotary breaker customers get the ideal machine for their requirements. Product specialist Etienne Swanepoel explains that this test is used to accurately size the rotary breaker needed for customers’ specific applications, based on coal hardness.

He outlines what the test entails.

“Sample lumps of coal and stone approximately 300mm in size are elevated and dropped from a predetermined height onto a rotary breaker screen plate. Broken material is then screened and each fraction is weighed.  Material bigger than the product size is dropped again, and the screened undersize is discarded.

Namibian aggregate producer opts for Osborn modular plant

Namibian aggregate producer Henning Crushers has opted for a 300 tph Osborn modular crushing and screening plant to boost the capacity of its Tsumeb operation.

This R40-million export order reflects Osborn’s expanding footprint in the Namibian market, and the Osborn modular plant’s growing reputation as an unrivalled solution for plant expansion, comments export sales manager Douglas Mouton.

Shining performance leads to Tanzania export order

An R8-million export order for two Osborn Telsmith 36 x 48 Single Toggle Jaw Crushers and an apron feeder - to be employed at Petra Diamonds’ Williamson mine in Tanzania - has been awarded to Osborn.

This is the latest in a series of orders that the Johannesburg-based manufacturer has received from Petra Diamonds. Osborn’s Chris Slade elaborates: “Osborn already has jaw crushers and apron feeders in this application at Petra operations in South Africa, and these have proved themselves over the years. Osborn has also previously supplied an apron feeder to Williamson mine in Tanzania’s Shinyanga Province. This latest order reflects our client’s confidence in our products’ quality and performance.”
