Limestone is a common non-metallic mineral and a valuable resource with a wide applications. In modern industry, limestone is the main raw material for the manufacture of cement, lime, and calcium carbide. It is an indispensable flux limestone in the metallurgical industry. After superfine grinding, high-quality limestone is widely used in papermaking, rubber, paint, coatings. And other products are being manufactured. With the continuous progress and development of science and technology, the application field of limestone is further expanding. Limestone can be used in many fields after being pulverized and processed by a mill, and considerable economic benefits have been achieved. In recent years, the limestone powder processing industry has gradually become hot, especially in the field of serialized, refined and functionalized limestone deep processing and power plant flue gas desulfurization. And other environmental protection fields have huge market prospects.

Dawn grinding mill helps users become bigger and stronger, and always uses strength and attitude to bring better benefits to customers. Recently, the installation and commissioning of another MTW European mill in Northwest China has been completed, and it has been successfully put into production. The main equipment of the production line adopts the MTW European mill from Dawn machine group.

Do u know the jaw crusher  how to working ?

China jaw crusher is widely used to crush medium sized granularity of different ores and bully materials with compressive strength less than 250Mpa in mining, metallurgy, building materials, highway, railway, water conservancy and chemical industries. Therefore, jaw crusher is also called as limestone crusher, granite crusher and cobblestone crusher.There are two types of Jaw crusher: coarse jaw crusher and fine jaw crusher.

The jaw crusher adopts crank link mechanism. Additionally, every moving track of the dynamic jaw is an arc with the mandrel as its center. The circular arc radius equals the distance from the point to the axis with the upper arc being smaller and the lower arc bigger.

Mobile crushing stations are widely used in mining, metallurgy, building materials and other industries due to their walk-and-stop nature. They are especially popular in companies that need to process raw materials that are not fixed. The configuration of mobile crushing can be adjusted according to production needs. In the crushing and processing of stone materials, in addition to mobile jaw crushers, there are mobile impact crushers and mobile cone crushers that meet the requirements. This article introduces relevant information about mobile jaw crushers.

1. Introduction
The mobile jaw crusher is a mobile crushing station equipped with a jaw crusher. By carrying the jaw crusher for initial crushing, various massive and granular large stones such as bluestone, pebbles, granite, etc. can be turned into uniformly grained sand. Meet the requirements of the feed inlet of the sand making machine, with large output, large crushing ratio and uniform product size.

In actual production, both of them have many differences, as follows:

1. Different hardness of the crushed materials

Cone crusher mainly crushes some big hardness materials, such as granite, basalt, tuff, river pebbles and so on; while impact crusher is used to crush the materials with small hardness, such as limestone, limerock, etc.

2. Different discharge sizes and applied materials

Generally, the discharge granularity of cone crusher is finer than that of impact crusher. In the actual production, cone crusher is used more in ore processing, and impact crusher is used more in building materials and construction industries.

3. Different grain shapes of finished products

The grain size of impact crusher is better, and the finished products has less edges and corners, more powder. There are many needle-like pieces in the finished products of cone crusher, and granule shape is not good.

4. Different investment cost

The price of cone crusher is higher than that of impact crusher, but the wearing parts has long lifespan, which avoids the trouble of constantly replacing components. In the long run, the cost performance of cone crusher is higher than the impact crusher. It can be understood that the pre-purchase cost of the impact crusher is low, and the post-maintenance cost is high; the pre-cost of the cone crusher is high, and the later input cost is low.

5.Different pollution degree

The noise dust pollution of impact crusher is big, while, cone crusher is relatively small.
