The sand making machine has poor output and low sand production. I want to know why. In actual production, the output of sand making machines is related to many factors such as material hardness, humidity, finished sand fineness, equipment maintenance, and equipment quality. The hardness, viscosity, and humidity of different crushing materials may vary, and the sand output of the sand making machine during crushing will vary according to the different crushing materials.
The specific situation is as follows:
1. The higher the viscosity of the material, the greater the possibility of adhesion. Materials with high viscosity will adhere to the inner wall of the sand making chamber. If not cleaned in a timely manner, it will seriously affect the efficiency of the sand making machine and even affect its normal operation. Therefore, when selecting materials, we must pay attention to the viscosity of the materials not being too high.
2. The more fine powder is contained in the material, the greater the impact on sand making, as these fine powders are prone to adhesion and affect transportation. Therefore, for materials with high content of fine powder, it is necessary to screen in advance and try to select fine powder from the materials as much as possible to avoid affecting the operation of the sand making machine.
3. When materials are crushed in the sand making machine due to high moisture content, they are prone to adhesion and blockage during the feeding and conveying process, resulting in a decrease in the sand making machine's output. Firstly, when selecting materials, the humidity of the materials should be strictly controlled. If the humidity of the material is too high, it can be reduced by sunlight or air drying.
4. The harder the material hardness, the more difficult it is to make sand, and the more severe the equipment wear. This indicates that materials with moderate hardness should be selected when selecting materials.
The higher the requirements for finished sand with different fineness, that is, the finer the finished material, the smaller the sand making ability. This is related to the needs of sand making users, and the material fineness is generally medium fine. The differences in sand making machine models vary from manufacturer to manufacturer, and the sand production and energy consumption of different equipment models during operation also vary. 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, but also cause users to spend higher costs. Standardized operation, regular maintenance, and regular maintenance of the sand making machine are very important and can also affect the sand production volume of the equipment. The continuity and uniformity of feeding have a significant impact on crushing. Continuous and uniform feeding not only ensures normal production, but also improves productivity. If the operation of the sand making machine is not standardized and not regularly maintained, it will accelerate the wear of vulnerable parts, greatly reduce the service life of the equipment, and reduce production. High quality sand making machines not only save energy and environmental protection, but also can easily achieve the expected output. High quality manufacturers will choose new wear-resistant materials and adopt leading production technologies, and the equipment produced can meet the production needs of users.
Design of Sand Production Line Scheme
The final output is related to the equipment of the entire production line. For example, if the output requirement is 500t/h, not only is the hourly output of the sand making machine required to reach 500t, but also the processing capacity of the front jaw crusher, cone crusher, and belt conveyor must be matched, otherwise the final output will definitely not meet the requirements. The configuration of the production line should comprehensively consider various factors to meet production needs.
The influence of impeller speed
Continuous materials enter the high-speed rotating impeller and accelerate to form a stable dynamic material flow, which generates high-speed compression, grinding, and crushing in the vortex chamber, resulting in continuous crushing production. From the working principle of the vertical axis impact crusher, it can be seen that when the particle size of the material is determined, the kinetic energy greatly increases with the increase of the linear speed of the crusher rotor; When the linear speed of the crusher rotor is determined, if the material quality increases, the kinetic energy will also increase, and vice versa.
The particle size of crushed stones broken by a vertical impact crusher is related to the linear speed of the crusher's rotor. Under the same working conditions, if the particle size of the crushed material is large, the linear speed of the crusher rotor is lower. Therefore, when the material crushing strength is high or the crushing particle size is small, the required crushing speed should increase. When the feed particle size, moisture content, and feed amount are the same, increase the crusher rotor speed (linear speed) appropriately to increase the fine powder production.
The impact of work parameters and operational factors
The performance and structural factors of sand making machines have a significant impact on crushing. The type and specifications of the sand making machine, the economical and reasonable installation power, the range of speed adjustment, the size of the outlet, and the structural form of the crushing chamber all have a significant impact on the crushing efficiency.
The inability of the sand making machine to achieve the original production capacity is closely related to the above 8 factors. Users should consider their production situation comprehensively when purchasing, in order to find equipment suitable for their material crushing.
