Several Factors Determining the Sand Output of the Crawler Mobile Sand Making Machine

Serveral factors determining the sand output of the crawler mobile sand making machine

Crawler mobile sand making machine has many outstanding features such as fluidity operation, modular process formation, high output and high efficiency. Due to the limited natural sand mining volume and the soaring sand price, it is currently sought after by industry users. Domestic crawler mobile crusher manufacturers vary, and the design of crawler mobile sand making machines varies widely. Tire-type mobile stations and crawler-type mobile stations are very different in overall structure, stability, durability, and output are also very different, so these two types of mobile stations will encounter selection phobia. So here the engineers of Luoyang Dahua explain the characteristics of crushed materials of the crawler mobile sand making machine in terms of structure, materials and application.

1. The water content and viscosity of the material

The moisture content of the material is humidity. The higher the humidity, the higher the viscosity and the smaller the particle size, the raw materials will agglomerate and stick to the inner wall and flow channel of the vertical impact crusher, and it is also easy to cause blockage near the discharge port, thereby reducing the crawler-type mobile sand making The efficiency and quantity of sand produced by the machine. Due to the actual situation of the project, under unavoidable circumstances, it is generally possible to increase the sunshine and air-drying time to reduce the humidity and viscosity of the materials and avoid affecting the production efficiency of the sand making machine.

2. Physical properties, such as compressive strength of raw materials

The first thing to consider is the compressive strength of the crushed raw materials of the tracked mobile sand making machine, that is, the hardness of the raw materials and the mechanical properties of the raw materials. For materials with high hardness and few internal texture gaps, the crushability is low. When processing such materials, the efficiency of the same equipment is relatively low, and the consumption of wearing parts is also relatively high. 

3. Feeding speed

Compared with the full-cavity feed of the crawler cone moving crusher, the crawler mobile sand making machine usually reaches its peak output when the input reaches 70% -90% of the impeller capacity. Too high will increase the abnormal wear of the lining, while too low will not reduce the sand production of the equipment.

4. Feeding granularity

At the beginning of the design, different types of crawler-type mobile sand making machines were set up, which exceeded the reasonable feeding range, which easily caused blockage and reduced the crushing efficiency. This is called "under speed"; too much fines will also affect the amount of sand produced by the sand making machine. In order to avoid these two deviations, it is usually necessary to configure a screening device at the front of the tracked mobile sand making machine to separate materials that are too large and too fine to improve the system.
