Rockster’s duplex system proves to be the ideal solution for processing lead ore

The P.B. Mining Company has invested in the “2-in-1” Rockster solution for crushing highly abrasive rock in the Mbeya Region in the United Republic of Tanzania.

The company’s many sites cover an area of approximately 80km2, with exploration works and excavation being undertaken by vertical and inclined prospecting drilling, driving of trenches, vertical and inclined holes. 

One of the sites is located near Chunya and here a Rockster R800 jaw crusher is used to crush the Galena excavated rock to 0-40mm.  In order to accurately produce a final grain size, a RS83 screenbox and RB75 return belt are used with the crushing plant. Following this the crusher ‘switches over’ to use the R900 impact crusher to produce a product size of 0-5mm. This material is then sent to a leaching company to separate the pure lead ore which is then used for the production of concentrates based on polymetallic ores.

Maksim Perminov, who commissioned the machine, and trained the operators, commented: “After finding out the requirements of the P.B. Mining Company I was sure that the Rockster Duplex-System would be the best solution to produce the final grain quality they need with the lowest costs possible. The uniformity of the ore mass is very important for them. As the Galena rock has a very high abrasiveness, it requires primary crushing by a jaw crusher to reduce the wear of blow bars when working on a rotary crusher.”
