PSK series crushers, which are jaw-adjusted impact crushers, are crushers that break medium and high hardness materials (such as limestone, dolomite, granite and basalt) in the size of asphalt and concrete aggregate. Coarse material feeding, cubic product, high reduction ratio, high capacity, low investment and operating cost have made this type of crusher the ideal secondary crusher in crushing and screening plants. The stone entering the crusher hits the crushing elements in the first region with the swing of the rotor hammers and the first crushing stage takes place. In this region, high pressure and breaking power are created to break even very hard materials. If the crushed material is in the desired dimensions, it passes to the second zone. The material passing to the second zone passes through another crushing stage and is reduced to smaller sizes. Then the material passes to the third and last zone and the final crushing process takes place. Now the material is reduced to the smallest dimensions. ADVANTAGES Wear-resistant crushing elements High crushing capacity High reduction rate Hydraulic body opening Possibility to use both sides of the pallets
