Factors Of Low Sand Production Of Sand Making Machine

Recently, some users said that the output of their sand making machine is not good and the sand production is low. They want to know why. In actual production, the output of sand machine is related to many factors, such as material hardness, humidity, finished sand fineness, equipment maintenance and equipment quality, etc.

1. different crushing materials

The hardness, viscosity and humidity of different materials will be different to some extent. The amount of sand produced by the sand making machine during crushing will also be different according to the different materials. The details are as follows:

(1) viscosity of materials

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 sand making chamber in the sand making machine. If it can not 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 to the viscosity of materials.

(2) material composition

The more fine powder contained in the material, the more influence the sand making, because these fine powder are easy to adhere and affect the conveying. Therefore, the material with more fine powder content should be screened once in advance, and the fine powder should be screened out from the material as far as possible, so as not to affect the work of the sand making machine.

(3) material humidity

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

(4) material hardness

The harder the material is, the more difficult it is to make sand, and the more serious the wear of the equipment is. This shows that the hardness of the material should be moderate.

2. Different fineness of finished sand

The higher the fineness requirement is, that is, the finer the finished material is, the smaller the sand making capacity is. This is related to the requirements of sand making users. Generally, the material fineness is medium fine.

3. differences of sand machine models

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

4.whether the operation is standardized and the maintenance is regular

It is very important to operate and maintain the sand making machine regularly, which will also affect the sand production of the equipment. The continuity and uniformity of feed have great influence on crushing. Continuous and uniform feed can not only make production normal, but also improve productivity. If the operation of sand making machine is not standardized and regular maintenance is not carried out, the wearing of vulnerable parts will be accelerated, the service life of equipment will be greatly reduced, and the output will be smaller.

5.quality of sand making machine

High quality sand making machine can not only save energy and environmental protection, but also easily achieve the expected output. And high-quality manufacturers will choose new wear-resistant materials and adopt more advanced production technology to produce equipment that can meet the production needs of users.

6. Scheme design of sand production line

The final output is related to the equipment of the whole production line. For example, if the output is required to be 500t / h, the output of sand making machine can not only reach 500t per hour, and the processing capacity of jawbone breaking machine, cone breaking machine and belt conveyor in front of it must match with it, otherwise the final output will certainly not meet the requirements. The configuration of a production line should consider all factors comprehensively to meet the production demand.

7. The influence of impeller speed

Continuous materials enter the impeller with high-speed rotation, and after acceleration, a continuous power material flow is formed. High speed extrusion, grinding and crushing are generated in the whirlpool chamber, resulting in continuous crushing production. From the working principle of vertical shaft impact crusher, it can be seen that when the particle size of the material has been determined, the kinetic energy increases greatly with the increase of the linear speed of the crusher rotor; when the linear speed of the crusher rotor is constant, if the mass of the material increases, the kinetic energy also increases, and vice versa.

There is a certain relationship between the particle size of stone crushed by vertical shaft impact crusher and the linear speed of the crusher rotor. Under the same working condition, if the particle size of the crushed material is large, the linear speed of the crusher rotor will be low. Therefore, when the crushing strength of the material is large or the crushing particle size is small, the required crushing speed will increase. Under the condition of the same particle size, moisture content and feeding quantity of the materials, the rotor speed (linear speed) of the crusher shall be increased properly, and the output of fine powder shall be increased.

8. Influence of working parameters and operation factors

The performance and structure of sand machine have a great influence on crushing. The type and specification of the sand making machine, the economic and reasonable power of the machine, the range of the speed adjustment, the size of the ore discharge opening and the structure of the crushing chamber all have a great influence on the crushing efficiency.

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