duel drive arrangement in ball mill

the hot commissioning have shown that the drives can even operate in inching mode at as little as 1% rated speed (mill speed 0.10 rpm). On a large dual pinion mill, using the ABB drive to rotate the mill for maintenance is an advantage over an inching drive, because the inching torque is transmitted by the dual drive system to the

Ball Mills are almost indispensable to Industries manufacturing Paints, Chemicals, Lime-Pazzolana, Cement, Inks, Pharmaceuticals, and Mineral Mixtures and other allied Industries. Ball Mills employ modified drive arrangement to reduce the Mill cost as well as for smooth trouble free operation.

In case of dual arrangement, where two gear units are installed on both sides of large ball mills, one spare unit fits both sides. And in case of worn-out teeth you can simply turn the MAAG LGDX upside down and operate on the back flank of the gearing, thanks to the symmetricity of the housing.

The two installed mills include a semi-autogenous (SAG) mill measuring 10.4 x 6.1 m with a drive output of 15 MW; and a ball mill rated at 18 MW. The SAG mill reduces ore fragments with a maximum size of 250 mm (P80 = 152 mm) down to 2 mm, and the ball mill reduces the SAG mill product to about 74 µm. Grinding is followed by flotation.

Dual Planetary Ball Mill. Model No.: SXQM-0.4 Brand: TENCAN Applications: SXQM series of dual planetary ball mill is a kind of essential devise for labs, which want to mix, grind or produce high-tech new material in small lot. It is widely used in the following industries such as electronic, magnetism, medicine, ceramic, geology, mineral, metallurgy, build material, chemical, light industry ...

The gearless drive design was not applied to the mills in the mineral industry until 1981 when the then-world's largest ball mill, 6.5 m diameter and 9.65 m long driven by a 8.1 MW motor, was installed at Sydvaranger in Norway (Meintrup and Kleiner, 1982).

An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically ...

Once running speed is reached, the ball or autogenous mill load torque smooths out, but the rod mill does not. Jackstrawing of worn rod pieces and other characteristics cause it-to continue surging. While mill inertias are high at the mill, they are reasonably low referred to the drive motor(s) through the gearing.

Among the different types of horizontal mills used in the mining industry, SAG, AG, rod and ball mills are usually equipped with lateral drives. We offer you a full package of complete drive systems, consisting of girth gears for single or dual drive pinions, main gear units and auxiliary drives.

The QdX4 mill drive system uses traditional engineering load distribution calculations for sizing standard baseplates and hold-down anchor bolts, very similar to that seen with dual-pinion drive arrangements. The Qdx4 mill drive system is estimated to take less than one-third the time to install when compared to a GMD system and can ...

Different drive arrangement for ball mills are in existence. Commonly existing arrangement is mill drives with a girth gear and a pinion driven by motor with a gear box. Larger mills have a twin drives of half the ratings on either side of same girth gear. In central drive arrangement both the girth gear and pinion are avoided by connecting ...
