Electrically operated stone crushing plant is very common in quarry site. Recent years, SBM stone crushing equipment has been popular in the world. In Zambia, SBM electrically operated stone crushing plant can be seen in many mining processing sites.Stone crushing plant produced by shanghai SBM has its unique characteristics as well as guaranteed quality. For all mining machine producers are many in the world, shanghai SBM has expanded its business to more than 170 countries.
Here Is A Brief Introduction Of One Of SBM Crushers
SBM HPC series multi cylinder hydraulic cone crusher is a new generation of cone crusher on the basis of more than 20 years' experience in R & D of the crusher and the combination with foreign advanced technology.
HPC series multi cylinder hydraulic cone crusher breaks through the design concept of traditional cone crusher and adopts advanced fixed spindle and the eccentric sleeve structure rotating around the spindle. And the laminating crushing principle significantly improves the crushing capacity and the quality of products. The design of Hydraulic and lubrication systems not only can ensure the reliable operation of equipment, but also greatly reduces the time and manpower.
When HPC hydraulic cone crusher machine is at work, the motor through the belt, transmission shaft, bevel gear pair drives the eccentric sleeve to rotate and the moving cone does the rotating swing motion under the action of the eccentric sleeve to make moving cone and fixed cone sometimes be closer or deviation. The materials are being squeezed, impact, crushing in the crushing cavity and finally are discharged from the lower.
The Zambian economy has historically been based on the copper mining industry. Output of copper had fallen, however, to a low of 228,000 metric tons in 1998, after a 30-year decline in output due to lack of investment, low copper prices, and uncertainty over privatisation. In 2002, following privatisation of the industry, copper production rebounded to 337,000 metric tons. Improvements in the world copper market have magnified the effect of this volume increase on revenues and foreign exchange earnings.
