Impact crusher three advantages produce high-quality stone

The outer surface of the stone is angular, with a rough surface texture, a large specific surface area, and a firmer bond with the asphalt. The strength and durability of the road surface will be better. For the whole production process of the Kaishan ore, it mainly controls the flatness of the finished product. The content of prolate granules can guarantee the overall quality of products. According to the production experiments and practices of stone crusher experts, Red Star Machines believes that the entire production process can be controlled in the following ways in order to produce high-quality stone materials:

Advantages 1. Cycling load

In a closed-circuit cycle production process, the impact crusher adjusts the discharge opening and increases the load in the circulation. The shape of the stone will become better. During the entire process, the wear of the equipment in the system increases due to the increased cyclic load. However, when the discharge outlet is adjusted large, the load of the main crushing motor can be reduced and the finished product can be deformed.

Advantage two: Broken ratio

The crushing ratio of the impact crusher is the ratio of the particle size of the imported material and the finished product after crushing. The larger the ratio, the greater the crushing ratio, and vice versa. The crushing ratio is greater than that of large needles. Moreover, this rule is applicable not only to impact crushers and jaw crushers, but also to cone crushers and European crushers. It has nothing to do with crusher models. If the crushing ratio is too small, the output of the entire system will decrease, the internal circulation will increase, the crusher wear will increase, the economy will be poor, and the production benefit will be low. Therefore, in the entire production process, it is very important to choose the proper crushing ratio.

Advantages Three, open and closed loop

In the secondary crushing process, the circulation is separated from the road circulation and the closed circuit circulation. The former is called the first screening and the latter is called the first grinding after the screening. The first screening after the grinding means that the material after the first crushing is passed through the finished product. After the screening, it enters the secondary crushing feed inlet for crushing, so that the output of the finished product is increased, and the content of the pin sheet is also increased. The first smashing and sifting means that the first-level crushing materials all enter the feeding port of the second-stage crusher, and then it is broken and then enters the finished product to be screened. The entire system is a closed system, no broken material is lost, and the circulation load is large. , but the product shape is good.

The choice of stone for road construction is very important. The quality of the project is related to people's life safety. At present, the stones used in the construction of roads in China are mainly produced by crushing with impact crushers. In addition to the excellent mechanical properties of natural sand, the stones are mainly cuboidal and multi-angular. The characteristics can ensure the tight integration between the stones and improve the overall strength of the road surface. Our constant supply of Red Star is also the key to improve the quality of the finished product. The impact crusher makes the stone in the crushing chamber affected by the two sides of the inner liner and the outer liner, and it is easy to form needles and sheets. If the supply is sufficient, The material entering the crushing chamber will achieve lamination and crushing, forming the crushing and grinding between the material and the material, and the shape of the finished product will become better.
