How to deal with unqualified discharge of mobile crushing plant

For the production process of mobile crushing plant, whether it is the occurrence of faults, the analysis of the reasons for the decline of output, or the solution to the problem of substandard discharge, are all important links in the production. These operations are designed to ensure production efficiency. The analysis of non-compliance causes shows that different phenomena are caused by different reasons. This is to introduce the problem caused by unqualified discharge.

Case one: crushing ratio

Comminution ratio refers to the ratio of imported material to the particle size of the comminuted finished product. The larger the ratio, the larger the comminution ratio, and vice versa. For the processing process of the mobile crushing plant, the larger the comminution ratio, the higher the water content of needle block. Therefore, in the production and manufacturing, the adjustment of comminution ratio is the key countermeasure to ensure the feeding. Maybe the comminution ratio is too small, which will lead to the whole system With the decrease of software production and the increase of internal circulation, the damage of the pulverizer is promoted, so the selection of pulverizing ratio must be appropriate;

Cause two:feed particle size

For m,obile crushing plant, different types or models can process different sizes of feeds. If the feed size is not appropriate, the output quality will not reach the standard. For example, when the feed size is reduced from 100 mm to 50 mm, the needle and flake content in the finished product will be reduced by 38%, so the feed size must meet the requirements of the production equipment.

Reason three: circulating load of mobile crushing plant

The working process of mobile crushing plant is in a closed cycle. When the discharge port is adjusted large, the load in the cycle will increase,and the shape of stone particles will be better. In the whole process, due to the increase of cyclic load, the wear of all equipment in the system will increase. However, when the discharge port is adjusted larger, the load of the main crushing plant motor will be reduced, and the finished particles will be well deformed. Therefore, it is very important to adjust the cyclic load in production.

Cause four:open circuit and closed circuit

In the production of mobile crushing plant, circulation is divided into loop circulation and closed-circuit circulation. The former is called the sieve before crushing, and the latter is called the sieve after crushing. Screening after comminution refers to that the material after primary comminution enters the secondary comminution feed port for comminution after screening the finished product. Therefore, the output of the finished material increases, and the content of needles and tablets also increases. Screening after crushing refers to that all materials after primary crushing enter the feed port of secondary crusher for secondary crushing, and then enter the finished product screen for screening. The whole system is a closed system, without the loss of broken materials, but the product has a good particle shape. In the actual production of mobile crushing plant, the discharge of mobile crushing plant can choose open circuit or closed circuit circulation according to the production requirements.

The above mainly introduces the cause analysis of the mobile crushing plant not meeting the discharge standard. The analysis of this problem is mainly from four aspects. The distribution is crushing rate, feed particle size, cycle load, open circuit and closed-circuit cycle. The above detailed analysis of the impact of these aspects on emissions requires that each factor be appropriately selected according to the production requirements in actual production.
