Installation, operation and maintenance of ball mill

Installation of ball mill

The quality of the installation is the key to ensure the normal operation of the ball mill. The installation method and sequence for all types of ball mills are roughly the same. To ensure smooth operation of the ball mill and to reduce the risk to the building, the ball mill must be installed on a reinforced concrete foundation of 2.5 to 3 times of its weight. The foundation should be laid on solid soil and should be at least 40-50 cm away from the workshop’s foundation. Read more

Jaw crusher operation and maintenance

Jaw crushers are generally installed on top of the concrete foundations. Take into consideration of the weight of jaw crusher, the tough working conditions and the high inertia forces generated by the machine during operation, which may cause the slight vibration of foundation and machine system; therefore, the foundation of the jaw crusher should be separated from the foundation of the workshop. Meanwhile, rubber or wood padding should be placed between the crusher foundation and the jaw crusher base frame to reduce the vibration.

In order to ensure the continuous operation of the jaw crusher to reach full production capacity, it is important to pay attention to the correct operation, regular maintenance and periodic overhaul of the jaw crusher. Read more

MINERAL DRESSING

The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate (enriched portion) containing most of the ore minerals and a tailing (discard) containing the bulk of the gangue minerals.

Since most ore minerals are usually finely disseminated and intimately associated with gangue minerals, the various minerals must be broken apart (freed) or “liberated” before they can be collected in separate products. Therefore, the first part in any ore dressing process will involve the crushing and grinding (which is also known by a common name called “comminution”) of the ore to a point where each mineral grain is practically free.
