Limestone is the main raw material for the manufacture of cement, lime, and calcium carbide. It is also an indispensable flux limestone in the metallurgical industry. After crushing and grinding, it is widely used in various fields of society. It is an indispensable and important raw material for the development of modern industry. , is also a non-renewable resource, so whether it can be used reasonably and efficiently is the basis for promoting industrial progress and sustainable development. The physical characteristics of limestone are low hardness and high brittleness. Combined with the principle of "more crushing and less grinding" in the limestone production line, we should try our best to produce the best particle size in the stage of crushing limestone, so the impact crusher equipment is most suitable for use. Crushing equipment used in limestone production line.

In actual production, the impact crusher is also the main crusher in the limestone crushing production line. The crushing characteristics of this machine are remarkable: the crushing chamber can receive and crush large pieces of material without compacting the material and overloading the crusher; the material can pass through freely during the extrusion interval, and the processing capacity is large; at a certain output Under the premise of particle size and processing capacity, the minimum power and liner consumption are guaranteed; the material particle size is uniform and the processing capacity is large. The crushing effect of the impact crusher on the material mainly includes the following several processes: firstly, the free crushing stage, the material enters the crushing cavity, and is immediately impacted by the high-speed blow bar, and the materials collide with each other, and the blow bar and the material and the material The friction between the crushing chamber makes the material in the crushing chamber broken, and at the same time obtains kinetic energy, and rushes to the impact plate at a high speed. After the material collides with the impact plate and is broken again, it is bounced back to the action area of the blow bar and is impacted by the blow bar again. . This is repeated until it is broken into the required particle size and discharged out of the machine.

According to market research, most of the limestone production lines of most enterprises will choose hammer crushers. As we all know, compared with the impact crusher, the hammer crusher has the advantages of small size, large processing capacity and good economy. So, what are the advantages of using impact crushers for limestone crushing compared with hammer crushers? Compared with hammer crushers, impact crushers have a larger crushing ratio and can more fully utilize the high-speed impact energy of the entire rotor .

At the same time, it is worth noting that: due to the relatively large loss of the blow bar, materials with relatively high hardness should not be crushed by the impact crusher. The impact crusher is very suitable for coarse crushing, medium crushing or fine crushing of brittle materials below medium hardness, such as limestone, coal, calcium carbide, quartz, dolomite, iron sulfide ore, gypsum, etc.
