Graded Crusher Improvement Program
As we all know, the crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machine arewinnowing mill, roll crusher, compound crusher. with a crushing ratio, uniform particle size, which having simple structure, reliable operation, easy maintenance, operating costs and economic these characteristics. PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact crusher machine, which is suitable for crushing hard materials, such as cement limestone crusher, it have the discharging size is small this advantage.
It is understood that the grading crusher during the improvement program , through the structure analysis of the tooth roller bearing parts . The parts have been improved, and the improved content of the improved structure forms are as follows:
(1) tubing connector is mounted on the bearing cap Bu,
instead of bearing housing, so that the Division to effectively solve the
problems of poor bearing lubrication grease can not fully enter the bearing
cavity.
(2) the original bearing sleeve are designed into two parts (bearing
housing and labyrinth ring) with bolt fastening. The bearings mounted to the
tooth roll shaft; simply labyrinth ring and seal ring installed in place, and
then the bearing sleeve and bearing simultaneously heated and mounted to the
tooth roller shaft and to avoid aging of the seals during heating problem,
extended seal ring life.
(3) reduce the maximum outside diameter of the
seal, leave sufficient space for maintenance. Easy installation and removal
tool, when the bearing is damaged, we can demode the bearing housing. And then
dismantle the bolt bearing sleeve bearing cover , demolition works its
demolition bearing replacement can unload damage. Increased bearing
maintainability.
(4)the ring of the puzzle palace processing an oil outlet
can solve the problem of bearings after a long run cause the bearing cavity
pressure within, and filled with grease so that at the labyrinth seal. The
labyrinth seal more reliably, can effectively increase the life of the seals and
bearings, PLC controlled automatic timing lubrication system. Do not worry about
the maze 2 holes on the oil port of excessive fuel.
After the improvement to the tooth roller shaft member, during actual use, the bearing and seal damage accidents are significantly reduced, while reducing the daily amount of maintenance to the grading crusher (one kind of mining equipment ).
