1. Repair and replacement of screen mesh
Standard wood flour machine screen is made of thin steel plate or iron piercing. When the screen is worn or broken down by foreign bodies, if the damage area is not large, it can be repaired by riveting or soldering; if the large area of damage, new screens should be replaced. When installing the screen, the burred side of the screen hole should be facing in, and the smooth side should be facing out. The screen sheet and the screen frame should be tightly bonded. When the ring sieve is installed, the stubble of the inner layer of the overlap should rotate in the direction of rotation to prevent the material from getting stuck at the overlap.
Two. Lubrication and replacement of bearings
The standard wood flour machine should be cleaned after 300 hours of work. If the bearing is lubricated by oil, when adding new oil, it is advisable to fill up the bearing seat gap of 1/3, not more than 1/2, before operation, just screw a little of the cover of the oil cup. When the wood flour machine bearings seriously worn or damaged, should be replaced in time, and pay attention to strengthening lubrication; use tapered roller bearings, should pay attention to check the axial bearing spacing, so that it maintains 0.2-0.4 mm, such as wood flour machine is not suitable, can be adjusted by increasing or decreasing the bearing cover paper pad.
