Limestone is commonly known as lime stone, and its calcium carbonate (CaCO3) content is usually about 92-93%, with a lumpy appearance and Mohs hardness of 3. After limestone is mined from limestone, it is crushed to form limestone particles, which is usually called sand and stone material, or further crushed to form limestone powder, which is widely used in building materials, highway, metallurgy, chemical industry and so on. Limestone grinding first process is crushing, so limestone crushing with which kind of crusher is better?
What are the commonly used limestone crushing machines?
Limestone is a soft stone, there are many kinds of limestone crusher on the market, such as: jaw crusher, impact crusher, cone crusher, etc., the performance of different crushers are different, the applicable materials are different, the effect of material crushing is also different, so which of these crushers is more suitable for crushing limestone?
PE Jaw Crusher
PE jaw crusher is a necessary equipment for crushing large limestone
Mainly used as coarse crushing equipment, the jaw crusher is responsible for high quality crushing in the sand and gravel production line.
Resistant to strong impact: split welded cast steel frame with simple structure and strong impact resistance; heavy-duty eccentric shaft and bearings ensure the impact resistance of the movable jaw assembly; heavy-duty guard plate is installed above the movable jaw to withstand the strong impact of materials.
Overload protection mechanism: When the equipment is working, materials that exceed its crushing capacity may enter, which will adversely affect the operation of the equipment and even damage the equipment, at this time the elbow plate will break by itself to protect the equipment from damage.
High quality material finishing: The jaw plate and side guard plate are made of high manganese steel, the elbow plate is made of gray cast iron, and the eccentric shaft is made of high strength forged steel, which is made after many times of mechanical processing, heat treatment and flaw inspection, with sufficient rigidity and strength.
Easy to operate and maintain: gasket type discharge adjustment device, centralized lubrication system, easy to operate and maintain; symmetrical structure of the jaw plate, which can be adjusted up and down after wear, increasing the use cycle and saving the replacement cost.
These are the reasons why the jaw crusher is more suitable for crushing basalt, not only that, its production capacity is also larger, with a production range of 1-1100t/h.
