Description

The Quarry Crusher is widely used for secondary and fine crushing in the fields of mining, building materials, metallurgies and so on. The Quarry Crusher can crush materials with middle and high hardness such as, ironstone, copper ore, granite, basalt, cobblestone, marble, limestone and so on. The Quarry Crusher is popular to be used in high automatic crushing line which has strict requirement for finished products’ shape and ratio. Features Of JOYAL Quarry Crusher: 1. Three kinds of hydraulic protecting parts (protecting oilcan, locking oilcan and hydraulic driving oilcan) not only protect the machinery, but also can deal with troubles without disassembly the parts. 2. Easy operation, reliable performance and can adjust the finished products sizes automatically; 3. The crushing chamber is specially designed according to particles-layer- pressure principle. The special chamber and the suitable rotary speed improve crushing ratio and capacity, so does the cubic product percentage. 4. If something abnormal happens, such as iron is feed into the crushing chamber or there is a jam in the chamber, the machine will lift up the cover and discharging the materials automatically. This eliminates the trouble of stopping the machine to discharge the material by workers, so the maintenance is easier, the cost is lower than spring cone crusher. 5. The Hydraulic Cone Crusher is adjusted by hydraulic device and lubricated by diluted oil. The labyrinth seal eliminates the defect of mixture between water and oil in the traditional spring cone crusher.
