③开启比重分级去石机，正常运转后进料并调节喂料门，料流均匀并使料面高度

③Turn on the specific gravity grading stone remover. After normal operation, feed the material and adjust the feeding door. The material flow is uniform and the height of the material surface is about half the height of the transparent glass. After a few minutes, the stones will appear behind the reverse blowing plate, which improves the reaction. Blow the board to the position where the stones start to be discharged normally. If the blowback board is opened, no stones are discharged. The front inclination adjustment device can be adjusted appropriately to make the inclination of the screen surface smaller. If the discharged material contains stones, the suction volume can be increased appropriately; <br>④The proportion of light flow and heavy flow is realized by changing the suction volume. The air volume is large and the light flow is large. Otherwise, the second screen in the upper screen should be replaced. , The third stage of the screen surface to achieve.

(3) open the gravity grading stone machine, normal operation of the feed and adjust the feeding door, the material flow is uniform and make the material surface height to half the height of the transparent glass, after a few minutes, the stone will appear after the anti-blowing plate, improve the anti-blowing plate to the stone began to discharge normal position, if the anti-blower plate open large, no stone discharge, can be appropriately adjusted the front inclination adjustment device, so that the sieve angle is small. If the discharged material contains stones, the amount of suction can be appropriately increased;<br>(4) The proportion of light flow and heavy flow is achieved by changing the amount of air absorption, the air volume is large and the light flow is more, otherwise the second and third sieve surfaces in the upper sieve should be replaced to achieve.

③ Open the specific gravity grading stone remover. After normal operation, feed and adjust the feeding door. The material flow is uniform and the material surface height is about half of the height of transparent glass. After a few minutes, stones will appear behind the reverse blower. Raise the reverse blower until the stones start to discharge normally. If no stones are discharged when the reverse blowing plate is opened, the front angle adjusting device can be properly adjusted to make the screen surface tilt The angle becomes smaller. If the discharged material contains stones, the air suction can be increased appropriately;<br>④ The proportion of light flow and heavy mass flow is realized by changing the suction air volume. The air volume is larger and the light flow is more. Otherwise, the second and third screen surfaces in the upper screen frame should be replaced.<br>
