The Ball Mill System (BMS) is a strongly coupled MIMO system,in order to implement a long-term automatic operation of the BMS effectively,and improve the automation level and efficiency, the paper present the overall design of the system,the control system is composed of Siemens SIMATIC S7-400PLCS7-200PLC,the PROFIBUS DP protocol and MPI protocol are both employed to setup a DCS.
To obtain a clear understanding of the proper and most effective application of VFDs, you first should gain a working knowledge of VFD basic theory as well as a strong familiarity with practical know-how Basic VFD Theory Applying a VFD to a specific application is no mystery when you understand the requirements of the load.
For ball mill grinding process random interference by many factors, processes complex mechanism, there is a big inertia and the lag, the fuzzy control theory is introduced into the mill control system, has strong robustness, can effectively overcome the mill main motor power nonlinear, time-varying factors such as interference System is reliable, adjust speed, anti-interference ability, can.

Ball mills for super-fine calcium carbonate Ball mill classifier systems have been improved over time and are now capable of achieving much finer products In the past, a particle size with a D97 of 10 microns was only possible Now particle sizes down to a D97 of less than 35 microns can be achieved, with a D50 in the range of 15 microns.
Ball mills are commonly used for crushing and grinding the materials into an extremely fine form The ball mill contains a hollow cylindrical shell that rotates about its axis This cylinder is filled with balls that are made of stainless steel or rubber to the material contained in it.
ball mill can be re-organised as  and , where B’Wio and A’Wio are the corrected operating work indices and WAG/SAG, WBM are the respective power draw of AG/SAG and ball mills Note that the ball mill operating work index is applied only on the portion that needs the additional grinding (Q2), which renders to the AG/SAG mill the.
CCVs are used for driving mine hoists, rolling mill main motors, ball mills for ore processing, cement kilns, ship propulsion systems, slip power recovery wound-rotor induction motors (ie, Scherbius drives) and aircraft 400 Hz power generation The variable-frequency output of a cycloconverter can be reduced essentially to zero.
