A. WOUND ROTOR MOTOR WITH POWER FACTOR CORRECTION CAPACITORS This is the most economical choice on a first cost basis. This solution meets the requirements of all gear trains on the market for ball mills.. With this type of drive arrangement, the acceleration time will be controlled by the ramp control used in the liquid rheostat.

The Colloidal Mill works on the rotor-stator principle. Due to shaving, when the material is pass between the narrow gap of rotor and stator milling surfaces, the size reduction is an effect. A rotor turns 3000-20000 rpm at high speeds. The high hydraulic shear levels applied to liquid disrupting structures in the fluid process.

If the ball mill will always operate at a fixed speed, the VSD is an expensive option. One major disadvantage of using a VSD or a fuid coupling, is that there is an additional 5% loss all the time that the ball mill is operating. The soft starter has only about 0.5% loss and a much longer expected life. Best regards,

The M350 is a 2 stage liquid resistance starter, each stage replacing. the equivalent of approximately 5 stages of fixed resistance.. The resistance units comprise electrodes (either 2 or 3) immersed. in electrolyte, contained within a 350 litre stainless steel tank.

speed of the mill between 50 and of the rated speed. This is achieved by changing the resistance applied to the rotor by means of the LRS. The higher the resistance on the rotor the lower the starting current, the higher the torque and the greater the percentage slip and therefore the motor will run slower.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

is currently the gearless mill drive (GMD). In GMD systems the motor's poles are directly installed on a pole flange on the mill shell, and the body of the mill itself becomes the rotor. Ring-geared mill drive For mills with standard diameters or requiring less than 20 MW (approx.) of power, ring-geared mill drives (RMDs) offer the best solution.
