The VSI sand making machine manufacturer tells you that the planned maintenance of the sand making machine can be divided into three types: minor repair, medium repair and overhaul.

VSI sand making machine manufacturers tell you that minor repairs and intermediate repairs are the main repair methods. Through minor repairs and intermediate repairs, the equipment is maintained during the two major repairs to make it work normally, and the content of the major repairs is determined. The VSI sand making machine manufacturer tells you that the interval between two repairs mentioned below is calculated on the basis of three shifts a day.
Sand making machine minor repair work: VSI sand making machine manufacturer tells you to check and repair the adjustment device, adjust the clearance of the unloading port, replace the worn liner and reasoning board, repair and replace the rotating parts, clean the individual parts of the crusher, replace the lubricating oil, repair and adjust Lubrication system, etc.
The VSI sand making machine manufacturer tells you that the interval between minor repairs of the sand making machine depends on the operation of the equipment, usually every half a month to once a month.
