This article is talking about other structure details.
6. Protection spring and hydraulic system
Protection spring is divided into two groups of four, respectively connected with the active roller bearing, bearing huge thrust when active roller works. Working pressure of the spring is designed according to the compressive strength of the material. This spring slightly slides during working time, when a piece of metal enters machine, this protection spring can quickly gives way and resets after the metal falls.
7. Bolts to fix spring
8. Top cover dismantling bolt
Taking down the pressure plate when opening dismantling bolt, open the entire cavity of the crusher can easily process failure or replace the two rollers.
9. Roller observation window
This window can be used as repair welding window. When the roller surfacing is damaged to a certain extent, repair welding can be done from this location.
10. Grease nipple
In order to ensure the machine to work properly, increasing the service life of bearings, used to refuel the machine by grease nipple timely.
11. Machine lifting hole
There are four lifting holes on both sides of the machine, for lifting the crusher.
12. Feeding inlet
Materials are fed into the crusher from this feeding inlet, feeder and distributor should be equipped on top of it so you can make the materials evenly fed into the crusher to ensure the broken particle size and protect the reasonable wear of rollers. When connecting with the feeder directly, the discharge hole and the feed inlet should be fixed by bolt according to the flange size.
13. Host pulley
Materials of host pulley adopt 45 steel casting, processed in machine tool, all the mechanical properties comply with GB/T11352-1989.
14. Adjusting bolt of fixed roller
There are four adjusting bolts on each side of the machine, they are used to fix roller bearing seat to the body, and use the four bolts to adjust the gap between the two rollers to control the particle size.
15. Foundation bolt hole
Foundation bolt holes are used to fix this equipment. When the machine works, it is bound to vibrate, so the host and motor (including reducer) must be firmly fixed on the foundation. The fix should in accordance with design size on drawings. When adopting concrete structure foundation, there should be secondary pouring hole or embedded bolts reserved; steel structure foundation, the high strength bolts should be adopted to fix
16. Bearing temperature sensor (users select the device)
Bearing temperature sensor is used to change the bearing temperature into an electrical signal and send it to the digital display instrument of the control cabinet) then accurate temperature values displayed. 8 sets in four -roller crusher, while 4 sets in double rollers crusher), staff on duty can observe the corresponding temperature of each bearing intuitively), if a bearing temperature exceeds the set temperature 80 degrees, the digital instrument would first make sound and light alarm, the maintenance personnel should immediately stop the machine and fill lubricate oil, when alarm lasts more than 30 minutes, roll crusher and belt machine will automatically shut down.
More information, even about failure, troubleshooting and maintenance, CONTRACT US, it is a pleasure to help you.
