Analysis of 5 common problems with stone removal machines

5 common problems with stone removal machines, now Yongming editor will analyze them with everyone.

1) Raw materials: moisture, particle size, uniformity, and the types and quantities of impurities in the raw materials are the main factors affecting the process efficiency of gravity separation equipment; If the impurity content in the feed is high, it will affect the normal feeding of the stone removal machine hopper. If the material contains a small amount of impurities, it is easy to block the sieve holes, which will disrupt the automatic classification of the material and reduce the separation efficiency.

2) Screen inclination angle: The screen inclination angle is related to the material flow rate. When other motion parameters are fixed, a small portion of the material will decrease with increasing tilt angle, while a large proportion of the material will increase resistance with decreasing tilt angle. In addition, the downward movement speed of the material on the screen surface will also increase, which affects the output of the equipment and is not conducive to the purity of heavy materials. (Add a cushion under the stone cleaning machine to change the inclination angle)

3) Amplitude and vibration frequency: Amplitude and vibration frequency are the main factors affecting the speed of material movement on a working surface. Large amplitude, high frequency, fast material movement, strong automatic classification function, which is conducive to improving the separation efficiency and output of the stone selection machine; But the amplitude is too large, the frequency is too high, the working surface vibrates violently, the material is prone to jumping, the automatic material classification is damaged, and the separation efficiency is reduced. On the contrary, the slow movement of materials on the screen surface and the thickening of the material layer are not conducive to the automatic classification of materials, which not only affects the separation efficiency but also affects the output of the equipment. The vibration frequency can be adjusted by replacing the belt pulley of the stone purifier, which is not easy to adjust

4) Flow rate: The material on the surface of the stone removal machine screen should have a certain thickness of material layer. The material layer is too thin to produce good automatic sorting, and it is easy to be blown away by the airflow. The airflow is unevenly distributed on the screen surface, which reduces the separation efficiency; The material layer is too thick, the air flow resistance increases, and the material is not completely filled. The contact opportunity reduces the distance between the material and the sieve surface and lowers the separation efficiency.

5) Air velocity: Typically, the average wind speed passing through the screen surface is 1.2-1.3m/s. If the wind speed is too low, it will reduce the air pressure on the material. The material is not easily suspended or semi suspended on the screen surface, and the automatic classification ability of the material is poor, which reduces the separation efficiency. If the wind speed is too high, the material layer on the removed surface of the stone is easily blown through, and the airflow distribution is uneven. The automatic classification of defective crushed materials can also reduce separation efficiency. (Small wind turbines can be replaced with larger ones, as the wind will drop; smaller wind turbines can also be replaced according to their own situation, as the wind will increase).

The above are the 5 common problems with stone removal machines. I hope it can be helpful to everyone. Thank you for your attention and support.
