How Raymond mill commissioning work: if we bought a new Raymond later, we can be assembled in their own factory, then assembled for just Raymond, they are not able immediately used in the production of them, since the main object Raimundo stone, hence the need for about commissioning work, otherwise it will be for Raymond is a very dangerous thing. For debugging Raymond machine should start commissioning start Mill, Raymond machine after installation, you can use the manual way to turn the disc, in rotation, the main observation there chuck phenomenon exists, if there is no card plate phenomenon, we can conduct a trial run to work. For the test approach is two ways: one is the no-load test mode, another way is to load test. We can according to their actual situation to select a test mode large milling machine, we also of two test methods are carried out, so that is more conducive to our safety tests. For no-load test, it is not in the case of feed for Raymond machine for testing. However, the no-load test we must meet the following conditions: first, in the electrical interlocking system test, then can start the program, so that start-up procedure and close the program are designed to meet the need; second, we must ensure it is members have stepped firmly; third, all of the flywheel can be rotated smoothly. Also in the running among the milling machine, we should always pay attention to the bearing temperature, preferably not more than thirty degrees. During operation among the Raymond mill, we want to keep the bearings lubricated properly, no leakage phenomenon. Raymond Mill development history of 1925 ECLoesche summarizes the first generation of the drawbacks of the use of the character and structure of coal mill Raymond, decided to further improve the structure of raymond grinding mill, management and development of a grinding mill as opposed to called modified Raymond. The main structure is characterized by ring grinding bowl rotation, the roller using a mechanical spring load pressure increased grinding force, the material is fed from the center of the ring by a rotating grinding bowl centrifugal force into the roller. Grinding roller shaft is fixed on a one-way movable arm, each arm can be adjusted by the grinding force of the control spring. This improved ventilation systems Raymond has positive and negative pressure blowing straight in two ways. This type of raymond mill patent soon to be US Combustion Engineering (Combustion Engineering) purchased. Because there are still Improved Raymond roller mill ring problems, although a slight increase in the roll diameter, but not grinding force increases. Later, the US subsidiary Combustion Engineering of Raymond and on this basis, developed a new generation of Raymond, called VR mill. In many respects this Raymond Loesche mill structure is now similar. It is worth noting that it is different from Loesche grinding tapered roller and flat disc, while using a cylindrical roller and grinding disc surface tilt angle of 15 degrees with use. Roller has in the inspection and maintenance and Loesche mill roller pulls a similar device, and also fitted with a protective device for children only wear metal contact between the roller and the disc. Also before starting the roller mill can be lifted ahead of time, so you can reduce the starting torque of the motor. Raymond industrial applications in the United States, usually used to prepare coal, changes in product fineness between 250-325 mesh, adjustable work product fineness and yield during operation.
