Mining machine pre-installation preparation

  • (1) When mining machine is transported to the site, the grinder mills should be properly kept from rusty parts after sun and rain if you cannot install the mining machine immediately. What’s more ,the mining machine should be coated with anti-rust oil once the metal processing is exposed to surface .If you have established a regular maintenance system to keep the good perfomance of mining machine , the grinder mill’s life time would be extended longer.
    (2) According to site-specific conditions and base map,make a good basis by using high-grade cement to configurate reinforcement and bury the threading pipe or make cable trench.
    (3) Cement base must have sufficient time to support solid-phase.
    (4) If you make rectangular configuration, you should consider the general map size of mining machine with sufficient height and location.
    (5) The installation site of mining machine should be provided with some lifting gears for installation or maintenance which is as follows: For the mining machine with 3R, starting weight of lifting tools should be 2t, and 4R with 2-3t,5R with 5t.
    (6) The main parts of mining machine ,such as roller device,central axis and oil pool of analyzer , should be cleaned and checked after using for 6 months.
    (7) After completely cleaning and checking ,you’d better add sufficient grease to every transmission section.
