Raymond Mill Using And Maintenance:

1. Besides raymond mill upper of main shaft using sliding bearings, all of other transportation parts using sliding bearings. So, the machine working at good lubrication condition, otherwise it will damage the bearings & reduce using life. The following are raymond mill maintenance methods: spindle refuel once per shift, but you must pay attention to that if inner the oil cup there is no oil loss or consumption to slow, you should first clean the oil pipe, then add 50# mechanical oil. Oil cup located in the upper of spindle, main shaft bottom seat bearings, roller bearings should add 3# lithium grease per shaft, analyzer bearings should open and clean per six months, then add enough 3# lithium grease, fan bearing chamber plus lithium grease.
2. Prohibited metal blocks enter into raymond mill, otherwise, the gringding roller and the gringding ring even the center hanger will be damaged.
3. Feeding should be uniform, can not be erratic. Feeding too much will block air passage, decrease the production capacity and damage the motor. But feeding too little will also decrease the capacity. Feeding size: hardness material diameter size should less than 15mm, soft material diameter size should less than 20mm, add big block materials to the raymond mill are forbidden.
4. Air flow capacity adjustment: the air flow capacity control valve located upper the fan intake duct, generally open to the maximum position, according to material fineness, production capacity requirements to adjust. Adjustment valve located upper waste outlet exhaust duct, open to the feeding port without powder outlet. Small air flow capacity, high fineness degree. Notice: air flow capacity too small, inner the raymond mill bottom air passage will precipitate material easily, please make appropriate adjustments.
5. Material fineness adjustment, according to different material size, hardness, moisture, proportion, the processing coarseness will also be different, you can adjust the analyzer, high speed, high fineness degree, low speed, low fineness. Improve the fineness, the production capacity will be reduced accordingly, if it still can't meet your requirements, you should adjust fan speed, user can flexible grasp.
6. Grinding roller and grinding ring scrapped limit is that it's smallest wall thickness should more than 100mm.
7. When stop working, stop feeding first, raymond mill continue working, grinding the residue material, one minute later, you should stop the machine, motor, analyzer motor working, then stop fan motor, to blow residual powder.
