Scrap crusher is an indispensable equipment in the steel industry, for the recycling of scrap steel has made outstanding contributions, but scrap crusher in the process of 24 hours non-stop operation, there are a lot of wearing parts will appear wear problems, resulting in equipment output can not reach, however, in the replacement of these wearing parts, there are the following things need to pay attention to:

First, bearing lubrication and replacement: scrap crusher every 300 hours after work, should clean the bearing, if the bearing is lubricating oil, add new oil to fill the bearing seat gap 1/3 is appropriate, can not exceed 1/2, before the operation only need to tighten the oil cup cover a little, when the scrap crusher bearing is seriously worn or damaged, should be replaced in time, and pay attention to strengthen lubrication; The use of tapered roller bearings, should pay attention to check the bearing axial spacing, so that it is maintained at 0.2-0.4 mm, if there is discomfort, can be adjusted by increasing or decreasing the bearing cover stainless steel conveyor ZSL series large cold ore vibrating screen paper pad.

Second, screen repair and replacement: some screen manufacturers are made of thin steel plate or iron sheet punching, when the screen is worn or broken down by foreign matter, if the damage area is not large, it can be repaired by riveting or tin welding; If the large area of damage, should be replaced with a new screen, the screen should be installed, the screen with burr side in, the light side out, the screen and the screen frame should be tightly fitted, the ring screen screen in the installation, the overlapping layer of the stubble should follow the direction of rotation, to prevent the material in the overlap of the feeder stuck scrap crusher.

3. Replacement of claw and hammer: Scrap crushing parts, crushing claw and hammer are vulnerable parts in scrap crusher, but also affect the crushing quality and productivity of the main components, crushing claw and hammer wear should be replaced in time, scrap crusher screw feeder tooth claw, should first pull out the disc, pull out before first to open the disc on the back of the round nut lock, screw off the round nut with a hook wrench, Then use the special puller to pull out the disc, in order to ensure the balance of the rotor operation, the teeth should be replaced in a complete set, the static balance test should be done after the replacement, in order to make the crusher work stable, the nut should be tightened when the jaw assembly, and be careful not to miss the spring washer.
