Maybe you will think that you do not know the pin mill as soon as you see it, As a matter of fact, the pin mill is also known as rod mill or grinding rod mill. That is to say, they are the same product. And today we will talk about the function of slow device in rod grinding mill.The main structure of rod grinding mill can be divided into 15 parts: 1. Tube feeding;2. Main bearing department;3. The hydraulic jacking device;4. High and low pressure pump station;5. Rotary department;6. Slow device;7. Drive department;8. Spray lubrication device;9. The intermediate shaft department;10. The screen;11. The coupling;Pneumatic clutch; 12.13. Synchronous motor;14. The electronic control system;15. The pneumatic system.Among them, the main bearing of rod grinder uses a totally enclosed type "joystick" since a self-aligning bearing, in the 120 oCentral bearing shell runs round, high pressure oil chamber in the bearing bush of babbitt alloy layer embedded within the "snake" cooling water pipe, bearing with ZDG - 63 - a type of high and low pressure combined pump station, oil bearing at the top of the lubricating oil pipe has connected to the low pressure oil pump, is at the bottom of the return pipe and high pressure oil pump connected to high pressure tubing, bearing with static pressure jack-up, characteristics of the dynamic pressure operation.The function of slow device in rod mill is mainly in debugging, maintenance and overhaul, with slow device to drive the mill when driving slow rotation and turning, convenient operation, to the practice of interlocking pneumatic clutch. At ordinary times complement steel bar with good machine add rods.Add bar for the first time in order to prevent the broken rubber lining board, must be manually add rods, until the bottom of the barrel of the reoccupy after covered with a layer of steel bar and rod machine add rods.And we also have other mining machines, such as China mobile crushers, ball mill manufacturer, screw washing machine and so on.
