CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
The Ball Mill Maintenance course is designed to engage in the effective use of handson learning methodology as a unique combination of theory and practical work section applied to the ball mill system's maintenance inspection.
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.

synchronous motor driven ball mill. The Benshaw variable frequency drive powers the 4160 volt 3500HP synchronous ball mill motor during positioning to smoothly rotate the ball mill and bring it to the proper position for maintenance. The customer's previous system utilized multiple DC contactors and a motorized cam switch to position the mill.
Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time delay characteristics also dynamics changes within 24 minutes. The fast dynamics necessitate closer attention to the
