The returning phenomenon occurs during the working process of the jaw crusher, which not only reduces the crushing capacity of the jaw crusher, but also affects its production capacity and must be eliminated. When the angle of the slab is enlarged, the smashing machine has a returning phenomenon. On the contrary, if the slab angle is made, the returning phenomenon will not occur.
 

Quartz sand is made of natural quartz stone. Quartz stone is also called silica. It is hard, wear-resistant and chemically stable. The processed quartz sand is an important industrial mineral raw material used in glass casting, ceramics, etc. In many fields, the market is very broad. Due to its high hardness, the user usually chooses more cone crushers. The cone crusher is specially developed for materials with higher hardness.

Jaw crusher is an indispensable equipment for many ore production lines. Its efficiency and advantages are obvious after many years of practice. However, most of the crushers crushed are high hardness ore. If it is not properly maintained, it will be seriously shortened. The life of the crusher will also increase the cost of the entire production line. The engineers of Zhongxin Heavy Industry will introduce the maintenance tips of the jaw crusher.

As the most commonly used crushing equipment for hard rock, cone crusher has high crushing ratio, low production efficiency, low energy consumption and good finished product effect, which brings high profits to the crushing work of sand and gravel industry. Now, with the development of society, the cone crusher has been developed into several types of crushing equipment. The choice of cone crusher is targeted, so how to choose the right cone crusher?
 

The price of the cone crusher is relatively high, and it is the wish of each customer to increase its output. Therefore, we need to pay more attention to the daily use of the cone crusher. The following points are the improvement of equipment output by Jiaozuo Zhongxin technical engineers based on years of experience. Operational precautions.
