Raymond Mill operational procedures and maintenance

A) Raymond Mill Preparations before installation

1 Raymond Millhas not yet run on-site installation. Exposed surface to be coated with anti-rust oil, and avoid the sun and rain to prevent rusting water body, to establish a maintenance system.

2, plant and equipment should be based on the basis of size of the chart according to Raymond Millshould have enough height and the installation location, high standard Raymond Millbase should be buried in cement and reinforced before being placed foundation, and to the buried pipe or cable channel threading. After pouring the cement foundation, must be home for a period of 15 days.

3 2 3 tons should be equipped with lifting tools for installation and maintenance with Raymond.

4 Raymond Millfrom the factory to the use of time beyond 6 months, the central axis of the host system, transmission device, roller device should be cleaned of oil pool inspection, cleaning After checking the various components should add enough oil.

B) Raymond Milldevices (according to different models of machines with different specifications detailed installation instructions and user manual, a technical engineer on-site guidance to the appropriate training)

A first gear hanging into the pit filled base, attention to good control of a certain height, then the top level of instrument calibration plane "A transmission device installed in the same time, the surface of degree A bolt.

2 Raymond Millhost installation. Device before the bottom of the base plane and the cement foundation and anchor bolts at the connection between exposure to mat rubber shock pad (see photo) and then use the box-shaped instrument calibration base level "B plane, calibration point for the cross-line four-point cross, while alignment of two half-coupling "CD to their different degrees should be less than 0.20 mm shaft, E1 E2 is not greater than 0.1 mm shall not be parallel, E1 E2 of the gap should be kept within 5-8 mm.

3, the location and height of the plumbing fixtures shall be installed total figure may not be any changes and heightening, the pipe connections should be sealed, after fastening may not have leakage phenomenon. Electrical equipment should be accurate and reliable, the components to be installed should be carried out after the test machine.

C) Raymond Mill debug:

An empty load running test machine, no load test machine before the grinding roller device should hold rolled firmly with a net ropes to prevent the grinding roller and grinding ring contact with the impact, then the host air test machine running at least 1 hour; host in should be smooth, cabinets oil temperature should not exceed 80 ℃, the temperature rise does not exceed 40 ℃. Analysis of the host machine and the direction of rotation shown in Figure 4

2 blowers should be no-load power, to be operating normally after the load, and then observe its smooth operation, no abnormal noise and vibration, bearing not exceed the maximum temperature of 70 ℃, the temperature rise should not exceed 35 ℃.

3 load test machine running time of less than 8 hours after the machine working properly Raymond Millno abnormal noise, the wind of the phenomenon of seamless pipe connection, the test machine again after the tightening of the tight solid, can be put into regular use. Raymond Milloperation process:
Pulverizer before starting, check all the access door is closed tight, jaw crusher plate check whether the feed size gap size, adjust the machine speed should be of similar analysis of product size requirements. Finally, the order of the boot 1 to start by bucket elevator; 2 starting jaw; 3, there are materials to be bin, start the analysis machine;

4 Start the blower (air load start running until after the load)

5 Start Raymond Millhosts, start host instantly starts electromagnetic vibrating feeder. At this point the work of Raymond Millmill is the beginning. Raymond Millsimple sequence of operations is as follows: Start: elevator crusher → → → fans of the host machine → → feeder. Raymond Millshutdown of the machine should be shut down following order: 1 to close the feeder stopped feeding; 2 stops after about a minute the host; 3 blowing off the residual powder will stop after the blower; 4, the final closure of machine. Raymond Millshutdown order is the feeder blower → → → Analysis of the host machine. Note: hoist a certain amount of material to the hopper, the first stop after stop crushing machine and upgrade the current changes in the feeding amount by the reservoir. 5 Raymond Millare not allowed to work freely in the normal fuel, to ensure production safety, the local mill occur at any unusual noise or a sudden increase of the load should immediately stop inspection, troubleshooting, in order to avoid a major accident. Then continue to boot more than expected the mill must be removed, otherwise the boot when the current is too large, of the startup.
