Ronghe Mining & Construction Machinery Co.,Ltd

We sell cone crusher, rock crusher, stone crusher. Our Product has been developed to crusher high or medium hardness material, such as iron ore ,copper ore, limestone, quartz, granite, and sand stones, ect, in metallurgical, construction, road building,chemical, silicate Industries. This crusher has the advantage of reliable construction, high prod activity, easy adjustment and less cost in operation. The spring release system of crusher acts an overload protection system that allows tramp to pass through the crushing chamber without damage to the crusher, use dry oil, water, two kinds of sealed formation. It made plaster stone and engine oil separated, assured reliable performance. The type of crushing chamber depends upon the size of feed and fineness of the crushed product. The standard type is applied to medium crushing, the medium type is applied to medium or fine crushing, and the short head is applied to fine crushing. The PY series crushers crushes by the change of the gap in the crushing cavity .The gap is opened and closed by the gyration of main shaft, which is derived by motor through cone gears. The PY series cone crusher is of high reduction ratio, high performance, low power consumption, and uniform size products. It has been used in the secondary and tertiary crushing. The crushing action is caused by the closing of the gap between the mantle line (movable) mounted on the central vertical spindle and the concave liners (fixed) mounted on the main frame of the crusher. The gap is opened and closed by the gyration of main shaft, which is driven by the eccentric sleeve. The eccentric sleeve is driven by the motor through elastic coupling, transmission shaft and cone gears. The cone crusher consists of body frame, transmission shaft, eccentric sleeve, bearing, breaking cone, supporting sleeve, adjusting sleeve, feeding part, spring, elastic coupling, lubrication part, electric part.

Vertical conbination crusher integrated the technology both home and abroad, optimized the main technology data, to make all kinds of best production to break concrete materials. It is the ideal new quality equipment for old and new concrete factories, and can break iron ore, sandstone, blast furnace slag, coal gangue, lump coal and so on.

VSI Sand Making Machine is a newly researched equipment, with international advanced level. Technology and modern processing equipment make it a leading role in this industry.Usage:VSI Sand Making Machine is widely used for artificial sand, in metal and non-metal ores, cement, refractory material, bauxite, silicon carbide, glass material, building material.Working Principle:(1) Center Feeding:Raw material falls down into feed hopper, then enter into impeller through central entrance hole. It is accelerated in high-speed impeller, then is thrown out at speed of 60-75m/s. When it hits impact plate, it is crushed. Final products come downwards though outlet. (2) Ring Feeding: Raw material falls down into feed hopper, then through ring, it is divided into two divisions by material-deviding plate. One enters into impellor through the center of material-deviding plate. The other falls down from outside of material-deviding plate. Material, which is thrown out by impellor at speed of 60-75m/s, hits material coming down from outside of material-deviding plate. In this way, material is crushed.
