We can provide all elements of a mill drive system as a fully optimised solution to suit your process exactly, or individual mill drive gearboxes, girth gears, pinions and couplings as required. Designed to deliver exceptional levels of performance and value, David Brown Santasalo ball mill drives are optimised for primary and secondary
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 matching mill required to draw this power is calculated from known tables the old fashion way.
Mill Girth Gears comprise high integrity girth gears that find application in driving horizontal grinding mills. With these gears developed for achieving superior finish strength and process reliability, these can be designed for different kW applications as well as in diameter and weight choices.
mills and ball mills for use in the mining and cement industries. By current standards, girth gears can be as large as 14 meters 46 feet in diameter, 1.1 meters 44 inches face width, and 50 module .5 DP tooth size, and weighing upwards of 120 tons. Flange mounted gears rely, in large part, on the mill structure to pro
the required mill speed in conjunction with open gear set ratio, and main drive gear reducer ratio where applicable. The normal duty of an incher is intermittent. Therefore lower service factors can be specified since the expected 25 years life of the mill kiln, the inching system would operate infrequently.
Metso is proud to announce the launch of our new rebranded offer Metso Gears and Pinions. A complete range of gear and pinion sets, inspections, design, installation and alignment services to drive your mills performance. You can expect the same quality supported by decades of gearing and OEM expertise.
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.

We are engaged in manufacturing and supplying Girth Gear, Industrial Girth Gear, Kiln Girth Gears. This girth gear is widely demanded in different industries to be installed in different machines such as Rotary Kilns, Rotary Dryers and Ball Mills, girth gear for ball mill, girth gear for cement mill, girth gear for raw mill, girth gear for rod mill, gear for ball mill, gear for rod mill, gear
how to estimate the wear rate for Ball mill Page 1 of 10. Dec 08, 2009 Re how to estimate the wear rate for Ball mill. Most practical way to by measuring empty height and calculating the volumetric filling of grindinge way to make track of mill main drive kW consumption reduction and add makeup charge according to the extent of fall in power consumption.
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.
PQN2 series planetary ball mills may be used for mixing, homogenizing, fine grinding, mechanical alloying, cell disruption, small volume hightech material production and even colloidal grinding. They are the ideal wetdry milling tools for acquiring research samples with high efficiency and low noise. Vacuum jars may be used to process sample within a vacuum environment.

GROSS POWER CALCULATOR General . measured at the shaft which drives the pinion gear in a gearandpinion drive. Apart from in pilotscale mills, the power at pinion is never directly measured in full scale operating mills but is estimated from the base are up to 40ft in diameter and ball mills are up to 26ft in diameter. The measured
Mills are driven by a circumferential drive with a gearbox DMG 2 with two integrated pinions via a girth gear or with a gearbox, countershaft and one pinion for mills with a smaller diameter. An auxiliary drive is used for turning of the mill drum during maintenance. Mill shell Mill seating Mill drive Range of twochamber mills
In comparison, a size 25.4gear unit for the SAG mill weighs about 36 mt, a size 30ballmill gear unit weighs as much as 70 mt. The DMG2 gear units used in this installation are about 30 more compact than a conventional gear unit solution, according to drive supplier Siemens.
These large coal crushing drive systems are usually rotated by motordriven gearing. A typical application consists of a motordriven primary singlestage reducer that, through a flexible coupling, drives a large open pinion which in turn, meshes with a large ball mill ring girth gear that is attached directly to the ball mill.
