Jaw crusher is used in the first crushing stage and it belongs to the primary crusher. Sometimes, the barite and benotnite in Nigeria needs to have the further crushing stage to get the desired materials size with impact crusher. The impact crusher has been designed to minimise maintenance and improve adjustment operations. It delivers unbeatable performances in primary, secondary, tertiary and recycling applications.
Jaw crusher is made of the frame, the eccentric shaft, a big belt pulley, the flywheel, a side guard plate, toggle plate, toggle plate backseat, clearance adjusting screw, a reset spring, a fixed jaw plate and a movable jaw plate, in which the toggle plate also plays the role of insurance.
Also, the HP900 cone crusher comes with a 360 feeding area. This combined with the higher stroke reduces bridging and allows for better top size acceptance. All resulting in maximizing performance.
It will be seen that the pitman (226) is suspended from an eccentric on the flywheel shaft and consequently moves up and down as the latter revolves, forcing the toggle plates outwards at each revolution. The seating (234) of the rear toggle plate (239) is fixed to the crusher frame ; the bottom of the swing jaw (214) is therefore pushed forward each time the pitman rises, a tension rod (245) fitted with a spring (247) being used to bring it back as the pitman falls. Thus at each revolution of the flywheel the movable jaw crushes any lump of ore once against the stationary jaw (212) allowing it to fall as it swings back on the return half-stroke, until eventually the pieces have been broken small enough to drop out. It follows that the size to which the ore is crushed.
Profast series is a new breed of mobile crushing machines engineered to handle even the hardest of rocks. It is ideal for producing high-quality aggregates and sand with multistage crushing and screening units and ensures trouble-free operation.
Function: for first primary crushing, and reduce stone size to smaller (like 30-50mm).
Knowing about Emipesa’s adjustment problem and the short lifetime of the liners, Metso started laboratory rock tests at the Metso factory in Mâcon, France; the liners of the HP200 should have a wear life of 180 hours. As a result of the tests, Metso recommended Emipesa to reduce the speed of the crusher from 850rpm to 700rpm.

The process of rock tumbling begins with rough edged rocks and ends with smooth rocks that have a polished surface. It may take a month or more for the stones to become smooth. A rock tumbler mimics the natural process of stone smoothing, where the stones in rivers and streams tumble due to the action of flowing water. The rocks inside the container are forced to topple on each other and simultaneously mix with the grit. As discussed earlier, use coarse sand in the initial stages of tumbling. As the stones get smoother, replace it with fine sand. The grit used in commercial rock tumblers is usually made from silicon carbide. You can use silicon carbide as grit for better results.
Vertical shaft impact crushers are generally utilized at the last stage of the crushing circuit, mostly in aggregates production and construction industry, but also preparing material feed for grinding mills in mining operations.
