Lubrication for 16X40 Three Roll Mill

Posted in Lubricating at 6:18 am by Administrator

Last week a US 16×40 three roll mill customer asked for detailed instruction for lubrication.

In our Owners’ manual, we wrote:

 machine lubrication and maintenance

       The machine has sealing lubrication structure for the gears. It is required to add industry gear oil; the oil lever should reach half of the oil gauge. It can not add more than that to prevent the oil from spraying out. The bearing base has been added oil before shipping, it is unnecessary to put more oil in for the new machine first time operation. After running 120 hours, the oil can be injected by oil injection tool.

1. The lubrication oil must be added into transmission axle through lubricating nipple.
2. Lubrication oil should be added very often at those places, such as: every adjusting screw, high/low speed roller bearing base and base orbit, to prevent the gear teeth from choking.
3. One major maintenance shall be carried out after six month continuous operation. Dismantle all those moving part and clean it. Apply new oil and inspect the oil cycling situation. Correct the problem if it is found.
4. If the concave area in the middle part of roller is found, surface material exfoliating or distortion is found, please stop operation and repair it immediately.
5. If the roller is repaired too many times and the roller diameter is more than 1.5mm smaller than nominal diameter, the gear transmission will conflict so that it will make the gap between rollers too big to grind the material well. The gear must be repaired under this condition to reduce its diameter, or the roller must be replaced.
6. The collecting blade edge must be very sharp and smooth. Burr and split are seriously prohibited. When the blade is short, just loose the screw to move the blade out. If the blade is finished and you change a new blade, please choose the right hardness usually between 30HRC and 40 HRC.
7. If the mill has not been operated for a long time, please apply anti corrosion grease on roller surface and other related place to avoid stain and pinhole. Thorough inspection shall be carried out before next operation.
8. If the cooling water flows into the machine, it means that the cooling water flow is too strong. So the incoming water controlling valve should be closed a little bit, and meanwhile loose the water drainage screw, let the water inside gear box flow out and increase the size of water drainage hose.
