Analysis of the common 5 points of stone removal machine

There are 5 common problems with stone machine. Next, Yongming editor and everyone will analyze it.

1) Raw materials: moisture, particle size, uniformity, the type and quantity of impurities in the raw materials are the main factors that affect the process effect of the gravity separation equipment; if the content of impurities in the feed is large, it will affect the normal feed of the lower hopper of the stone removal machine . If the material contains a small amount of impurities, it is easy to block the sieve holes, which will destroy the automatic classification of the material and reduce the separation efficiency.

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

3) Amplitude and vibration frequency: Amplitude and vibration frequency are the main factors that affect the moving speed of the material on the working surface. Large amplitude, high frequency, fast material movement, and strong automatic sorting function are conducive to improving the separation efficiency and output of the sorter; but the amplitude is too large, the frequency is too high, the working surface is violently vibrated, the material is easy to jump, and the automatic material classification is damaged. Reduce separation efficiency. On the contrary, the slow movement of the material on the screen surface and the thickening of the material layer are not conducive to the automatic classification of the material, which not only affects the separation efficiency, but also affects the output of the equipment. (Vibration frequency can be adjusted by replacing the belt wheel of the stone cleaner, which is not easy to adjust)

4) Flow rate: The material on the surface of the screen of the stone remover should have a material layer with a certain thickness. The material layer is too thin, it is not easy to produce good automatic sorting, and it is easily 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 chance of contact reduces the distance between the material and the surface of the sieve and reduces the separation efficiency.

5) Air speed: Generally, 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 easy to form a suspended or semi-suspended state 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 stone removal surface is easily blown through, and the air flow is unevenly distributed. The automatic classification of bad broken materials will also reduce the separation efficiency. (Small wind wheels can be replaced with larger wind wheels, and the wind will fall; smaller wind wheels can also be replaced according to their own circumstances, and the wind will increase).

The above are the 5 common problems of stone machine, I hope to help everyone, thank you for your attention and support.
