Pretoria Portland Cement (PPC) said yesterday it would invest R40m to increase capacity at its Laezonia quarry by 340,000tpa the installation of a new jaw crusher.
The Siyaya Egoli project would replace the existing jaw crusher, which had reached the end of its life span. The new crusher would provide greater flexibility in crushing the various rock types mined at Laezonia.
"This will not only increase efficiency and improve the output of our plant, but also help meet the demand in the Gauteng market," said chief operations officer Orrie Fenn.
Laezonia produces about 900,000 tons of amphibolite and granite products a year, which will increase to about 1.24Mt with the new crusher.
"In addition, ambient noise will be reduced with the complete enclosure of the screening buildings, whilst improved dust suppression systems will reduce the generation of material left over after the washing and screening process," Fenn said.
Construction began in June, with civil work, structural design and manufacture as well as the electrical design for the project all on schedule. Commissioning is planned for July.
