Oct 22 2016 V-BELT Ball Mill DRIVE. V-belt or poly-V drives are generally used on grinding mills consuming 350 HP or less. Where power exceeds this drives become so large and motors become special resulting in an uneconomical application. Generally the driven mill sheave is of split hub construction to facilitate field assembly.

Jun 19 2015 A motor with around 1400 Horse Power is calculated needed for the designed task. Now we much select a Ball Mill that will draw this power. The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the

Jun 13 2016 A vibration survey was carried on this Ball Mill with a duel pinion drive. The vibration is high in all planes on both sides of the Mill or both pinion drives. The measurements were similar in velocity on the motor gearbox and both pinion bearings. The recommendations for repairs was close to exactly the same for both drives.

Double planetary structure of dual planetary ball mill realizes movement of small disk driven by one large planetary disk. Compared with common planetary ball mill in same size revolution radius and rotation speed of mill jars have been enlarged greatly and centrifugal force of grinding balls is multiplied.

The subject of this paper is a synchronous drive of grinding ball mills 4 MW 150 rpm 6 kV 50 Hz on the base of PWM CSI. The system is installed at the

The time has come to re-think the approach to mill drive motors because of the growth in size of newer ball mills the starting torque restrictions of some of the newer mill drive configurations .

• Less bearing clearance and thus less mill shell deflection polysius ball mill with direct drive There are two types of gear unit available for the mill drive unit. For higher drive powers the combiflex gear unit is the unit of choice. The combiflex has an output of up to 8000 kW and with a dual drive up to 16000 kW.

One side drive provides a power range up to approximately 8000 kW when engaged with the girth gear of your ball mill. In dual arrangement with one gear unit on either side of the mill our MAAG LGDX gear unit covers grinding applications up to 14000 kW. Product features. Reliable gear unit components for a complete adaptable side drive.

Horizontal Ball Mill Drives. We can provide all elements of a mill drive system as a fully optimised solution to suit your process exactly or individual components as required. Designed to deliver exceptional levels of performance and value David Brown Santasalo ball mill drives are optimised for primary and secondary grinding applications .

Ball mill grate discharge with 40 charge and speed 75 of critical. For rod mills with 40 charge and 60 of critical multiply power figure by 0.60. Drive motor with min. 10 higher power should be chosen. Dual drive as per arr. 4. All measurements are for preliminary use only.

Flexible drive solutions for use in ball mills A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls.
