The drive components are the mechanical components that quot;drivequot; the CNC machine along its axis. The most common components associated with a drive system, are the motors, lead or ball screw, or rack and pinions. The whole idea of a drive system is to convert controlled rotary motion to controlled linear motion with the help of a CNC Controller.
Closed system to reduce dust: Ultrafine ball mill and classifier form a closed system with advantages of negative pressure delivery, low dust, reducing damage to the human body; Besides, the ball mill has higher product quality and cheaper operating prices.

Several types of ball mill drives can be furnished, made up of various combinations of gearing, motors and transmission equipment. The correct combination to be selected takes into consideration power requirements, gear ratings, floor space, interference from other plant equipment and motor characteristics. The main types are described and illustrated on these pages. Motors considered are
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 grinding applications.
Mill application features. Frozen charge protection Detects frozen charge in the mill, minimizing equipment wear and liner replacements.; Coupling supervision Detects if a failure or slippage occurs in the couplings and stops the system in case, preventing major damages.; Standstill detection Prevents the motors from restarting if the mill is still rocking or moving after a stop
Reliable ball mill efficiency with our compact central drive system. The design of our MAAG#174; GEAR CPU Gear Unit has been copied many times, but never equalled in efficiency, quality and ease of installation and maintenance. The complete central
The new drive systems will give a huge boost to the reliability and consequently also the throughput of the mills. The contract is valued in the doubledigit million range. The modernization project includes two 8 MW SAG (semiautogenous) mills and two MW ball mills with dual pinion drives.
Designed to deliver exceptional levels of performance and value, David Brown Santasalo ball mill drives are optimised for primary and secondary grinding applications. Extensively field tested and proven in harsh cement applications, our mill drive gearboxes cover all grinding applications up to 10MW per drive and we have single, double and triple
Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
optimum power transmission and speed reduction for your ball mill. The standard for central driven ball mills today, our MAAG#174; CPU Gear drives hundreds of raw and clinker mills all around the globe. Power efficiency exceeds % High operational reliability and availability Lowcost maintenance with longlife gearing and journal bearings

As such you will find it is designed and constructed according to heavy duty specifications. It is designed along sound engineering principles
Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.
or greater. Mill drive inchers can use this low value of service factor based on the limited operation over the twenty five year expected life. Regular inspections of the gear drive, control of moisture and dust ingress, and regular lubricant sampling and changes are required to have the expected life match the actual life of the drive system.
