The raw material from the mines consists of stones of various sizes from fines to large boulders. It is unloaded into the primary crusher hopper. The material is fed to the primary crusher via feeder. After primary crushing the material is conveyed to the hopper of the secondary crusher by belt conveyor. The material is further crushed and transferred to the screen for first screening. The 'oversize' from this screen goes to the tertiary crusher for crushing. The crushed material goes to the primary screen via the same belt conveyor (conveyor used to transfer the secondary crusher material). The 'through' from the first screen goes to the secondary screen for further screening and separation of different products and Dust. The dust is stored in hopper and directly unloaded into the truck. The products are discharged from the screen via conveyor belts to various stockpiles. From stockpiles the product is loaded into the trucks with the help of loaders and delivered at the point of use.

black stone jaw crusher operation

The main structure of jaw stone crusher are including frame,eccentric shaft,large pulley,fly wheel, movable jawstock,side guard, toggle plate,backseat of the toggle plate, fixed or movable jaw plate and so on.And the toggle plate have taken the secure effects.This working manner of jaw crusher is hyperbolic extrusion. And its working principle is as follows.Through the motor's wheels, the eccentric shaft is driven by the belt and the belt wheel to make the jawstock move by a regulated track. The angle between the toggle plate and jawstock will become large as the up of the jawstock. This will push the movable jaw plate towards the fixed jaw plate, which can realize the multi-crushing of the materials.The angle between the toggle plate and jaw stock will become small as the down of the jawstock. The movable jaw plate will leave the jaw plate at the pressure of the tension rod and spring, meanwhile, the final products will be discharged from the discharging opening. Along with the continuous rotating, the crusher will complete the periodic crushing and discharging movement, which can realize the batch process.

The distinctive feature of this class of crusher is the two plates which open and shut like animal jaws. This machine is powered by the motor connected to belts. The two jaws are set at an acute angle to each other. When one jaw is pivoted periodically, it swings relatively to the other fixed jaw. Materials fed into the jaws are alternately nipped when the swing jaw moves close to the fixed one. When the swing jaw moves away from the fixed one, the crushed materials will be released to fall further into the crushing chamber. Eventually, the crushed materials fall from the discharge aperture.
