How to Start a Ball Mill or Rod Mill Start the lubrication system and run it for about ten minutes, adjusting the oil flow at each bearing. Check all of the bolts and nuts on the mill for tightness and remove all ladders, tools and other obstructions prior to starting the mill.
05-12-2014· Clean Up The Machine After Use A ball mill should be cleaned up after every operation or at the end of the working day. The main components, such as the grinding tool, grinding roller, and grinding ring are prone to wear and tear.
production losses, which can be minimized by a cost-effective maintenance schedule for the optimum grouping of mill liners for combined replacement. The maintenance schedule depends on the lifetime of the mill liners. The life cycle cost (LCC) can be reduced further through optimum improvement of the lifetime of different parts of the mill liners.
Lubrication system is in the key part to reduce mechanical wear and tear, including the ball mill. Generally, you should replace all the old lubricating oil and clean the machine thoroughly after the mill was put into work as long as one month. After that you should change the lubricating oil about every six months for each time.
11-01-2016· A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.
Application of value engineering techniques to grinding process modelling led to the identification of two basic functions of the ball mill-classifier circuit. In terms of a specified circuit product size which is used to differentiate between “coarse” or oversize material and “fines” or undersize material, these basic functions are (a) breakage of the coarse material and (b) removal
Maintenance Schedule Before every wet machining process • Ensure that the water and Dentatec solution completely covers the filter(s) in the water tank Weekly • Change water in water tank and add 75ml Dentatec Monthly • Clean water filter monthly or as
Measurement of charge height is a convenient method to estimate charge volume. Generally : For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume .

Naturally other maintenance sharing models can be agreed and contractually arranged. One month is just one time frame for maintenance. Further examples exist for other maintenance timing such as the 6, 12 and 36 month services defined in the maintenance manual. The frequency of maintenance is proposed in the manuals and can be adapted.
Opportunities for improved mill control based on the data from the on-line monitor are also discussed, as well as the implications in terms of mill processing and maintenance performance. Recently a CSIRO monitor was also installed on a ROM ball mill and analysis of the vibration sensor data from this installation is currently underway.
Maintenance by Siemens Siemens has service engineers in the major mining countries who are trained in Gearless Drive technology. Siemens offers maintenance contracts tailored to your specifications. The main types are preventive maintenance with on-call service and performance-based maintenance contracts. Remote service
Preventive maintenance program is very important especially for the care and maintenance of industrial machines and plants and prevent our expensive assets from failure and unwanted downtime. Gone are the days when traditional maintenance schedule was followed as we can predict the condition of machines and replace parts when they are needed!
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
