8 factors affect the sand production capacity of sand making machine

Recently, some customers said that the output of their sand making machine was not up to standard, and the sand output was low, and they wanted to know the reason. In actual production, the output of the sand making machine is related to many factors, such as: material hardness, humidity, finished sand fineness, equipment maintenance and equipment quality, etc.

1. Different raw materials

The hardness, viscosity, humidity, etc. of different materials will be different to a certain extent, and the amount of sand produced by sand making machine will also be different according to the different raw materials. Details are as follows:

1) Viscosity of raw material

The higher the viscosity of the material, the easier it is to adhere. The material with high viscosity will adhere to the inner wall of the crushing cavity of the sand making machine. If it cannot be cleaned in time, it will seriously affect the working efficiency of the sand making machine, and even affect the normal operation of the sand making machine. Therefore, when selecting materials, we must pay attention that the viscosity of the materials should not be too large.

2) Material composition

The more fine powder contained in the material, the more it will affect the sand making, because these fine powders are easy to adhere and affect the conveying. Therefore, materials with a high content of fine powder should be screened in advance to screen out the fine powder from the materials as much as possible, so as not to affect the work of the sand making machine.

3) Moisture content of material

When the material is crushed in the sand making machine, if the water content of the material is high, it is easy to adhere, and it is easy to block during the feeding and conveying process, resulting in a decrease in the output capacity of the sand making machine. First of all, when selecting materials, the humidity of the materials should be strictly controlled. If the humidity of the materials is too high, sunlight or air drying can be used to reduce the moisture content.

4) Hardness of material

The harder the material, the more difficult it is to make sand and the more serious the wear of the equipment. So, we should choose material with moderate hardness.

2. Different fineness of finished sand

The higher the fineness requirement, that is, the finer the finished sand is required, the smaller the sand making capacity is. This is related to the needs of sand making customers. Generally, the fineness of finished sand is medium fine.

3. Differences in sand making machine models

The models of sand making machines produced by each manufacturer have certain differences, and the sand production capacity and energy consumption of different models of equipment during operation are different. When purchasing equipment, users should have a certain understanding of their own production, and purchase a suitable sand making machine; otherwise it will not only affect the output capacity, but may also cost the user more investment money.

4. Standard operation and regular maintenance

Standard operation and regular maintenance of sand making machine are very important, which will also affect the sand output capacity of equipment. The continuity and uniformity of feeding have a great influence on the crushing of sand making machine. Continuous and uniform feeding can not only make production normal, but also improve productivity. If the sand making machine is not operated properly and does not do regular maintenance, it will cause quick wear of wearing parts, greatly reduce the service life of the equipment, and reduce the output capacity.

5. Quality of sand making machine

The high-quality sand making machine is not only energy-saving and environmentally friendly, but also can easily complete the expected output. And high-quality manufacturers will choose new wear-resistant materials, adopt more advanced production technology, and produce equipment that can meet the production needs of customers.

6. Configuration of sand production line

The final output of sand making machine depends on the equipment of the whole production line. For example, if the output is required to be 500t/h, it is not only required that the hourly output of the sand making machine reach 500t, and the processing capacity of the previous jaw crusher, cone crusher, belt conveyor, etc. should also match it, otherwise the final output will definitely not meet the requirements. The configuration of a production line should comprehensively consider various factors in order to meet the production needs.

7. Influence of impeller rotation speed

The continuous material enters the high-speed rotating impeller, and after acceleration, a continuous power flow of material is formed, which produces high-speed extrusion, grinding and crushing in the vortex cavity, resulting in continuous crushing production. From the working principle of the vertical shaft impact crusher (sand making machine), when the particle size of the material is determined, the kinetic energy increases greatly with the increase of the rotor linear speed of the crusher; when the linear speed of the crusher rotor is balanced, if the material mass increases, the kinetic energy also increases, and vice versa.

There is a certain relationship between the particle size of crushed stone and the linear speed of the rotor of vertical shaft impact crusher. Under the premise of the same working state, if the particle size of the broken material is large, the linear speed of the crusher rotor will be low. It can be seen that when the crushing strength of the material is large or the crushing particle size is small, the required crushing speed will increase. In the case of the same particle size, moisture content and feeding amount of the incoming materials, the rotor speed (linear speed) of the crusher can be appropriately increased to increase the output of fine powder.

8. Influence of working parameters and operating factors

The performance and structural factors of the sand making machine have a great influence on the crushing. The type and specification of the sand making machine, the economical and reasonable installed power, the adjustment range of the rotating speed, the size of the discharge opening and the structure of the crushing cavity all have a great influence on the crushing efficiency.

The failure of the sand making machine to reach the original output capacity has a lot to do with the above 8 factors. Users should comprehensively consider their own production conditions when purchasing sand making machine, so as to find the equipment suitable for their own material crushing.
