After a long time operation, roll surface wear of Roller crusher would affect the crushing size and capacity, then we need to repair or replace the two rollers’ surfaces, methods are as follows:
Methods for overlaying welding roll surface
Repair is on the main body of the machine. Open endoscopic repair welding window, clean up the debris on the roll, observe the damage situation of roller surface, let skilled welders do the repair welding work by using ordinary DC welding machine and high-alloy hard facing electrode (or wear - resistant wire) same as original machine. Before the repair welding, first full fill the deep concave on roller surface by general welding rod and small steel blocks, then use hard facing electrode to make it same as out of factory. After welding, polish high parts on surface to be smooth by polishing machine, then it is all completed.
Methods for flat roller surface
Open the machine cover, remove the two roller assembly (including roller, fan-shaped plate, shaft, bearing seat and bearing) from the main body of the machine, then clean it up. Remove the bearing seat (including bearings)of the roller where contains the nuts. Loosen the nut on fan-shaped plate, remove the fan-shaped plate, pull out the fan disk and shaft on the other side, then remove the roller tube, finally make the roller surface flat on the lathe, it can be used again.
Methods for Toothed Roller surface
If the toothed roller surface cannot reach user’s requirement for crushing particle size, it need to change the tooth plate ( recommend, do not replace it until broken teeth are all abraded). Open the top cover, remove the two roller assembly (including multi-block tooth plate, circular plate, shaft, bearing seat and bearing) from the main body of the machine, and clean it up. Open all the bolts in inner roller which fix gear plate, unload the old tooth plate, clean up the inner roller and put the new tooth plate, tighten the mounting bolts of the tooth plate, job is done.
