    The gearless mill drive (GMD) has been continuously developed since its introduction in 1969. The Ball Mill SAG Mill maintenance instruction says that the bolts have to be checked and eventually tightened. If in previous

  • High vibration on the ball mill drive train A and B AMP

    We are experiencing high vibration on our dual drive ball mill. The high vibration is on the motor DE bearing on axial direction. Dominant frequency is girth and pinion gear mesh. See attached spectrums and trends. Gearbox hold-down bolts are breaking due to high vibration.

  • Ball Mill Variable Frequency Integrated Control System

    2. The ball mill frequency control and speed regulation system makes ball mill running reliably at low speed, ensuring the normal process control requirements. It extends service life of ball mill and reduces maintenance costs. 3. We can set different speed for different time frames according to the requirements of different grinding products.

  • Ball mill Wikipedia

    A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
