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, installed after Raymond machine, you can use the manual way to turn the disc, in rotation, the main observation there chuck phenomenon, if not chuck phenomenon, commissioning work can be carried out. 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, 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 of them, we should always pay attention to the bearing temperature, preferably not more than thirty degrees. During operation among mill price, we want to ensure the normal vertical milling machine bearing lubrication, no oil leakage phenomenon. River gravel grinding machines selected river pebbles need is a natural stone, taken from the experience of thousands of years ago after the crustal movement generated by the old riverbed gravel mountain ridge, the long-term impact of experiencing flash floods, water removal process continues extrusion, formation of friction. River gravel surface density of 2.5g / m3, a bulk density of 280kg / m3, robust indicators of 95-99.8%. River gravel main chemical composition is silicon dioxide, followed by a small amount of iron oxide and small amounts of manganese, copper, aluminum, magnesium and other elements and compounds, quality hard, with compressive strength, abrasion wear characteristics of natural stone, which is a ideal building material. After crushing river gravel as concrete aggregate, in construction materials market has a certain history and is widely mill, its main purpose is twofold: industrial and civil construction of concrete aggregates and Highway Construction level stable layer material. River gravel storage usually abundant and low mining costs, behind its economic development potential, revealing a huge demand for high-quality sand. After a river gravel crusher milling machine, which is mainly used in many sectors in mining, smelting, building material, highway, railway, water conservancy and chemical industries, breaking strength not exceeding 320 MPa of various materials. If you want river gravel grinding ground, you first need to go through river gravel crusher into the Raymond maximum feed size with the size, and then Raymond milling. When selecting Raymond model, we must first clear the milling of raw materials they need, when production and other issues.
