Mill drive 358 kw diaphragm double blind plate mill load control latest concept for cement mill optimisation 41 concept ms holderbank engineering canada has developed a control strategy for ball mills which can maintain a mill production near optimum with little operator intervention the main principle of the concept is that
Of a mill which is related to the mill load if a particular mill mass setting creates poor mill performance then a new mass setpoint will be needed in order to maximize power draw a pid controller is able to control only at the given setpoint and is unable to recognize such a development in the circuit it is also incapable of
Operation aim of ball mill grinding process is to control grinding particle size and circulation load to ball mill into their objective limits respectively while guaranteeing producing safely and stably the grinding process is essentially a multiinput multioutput system mimo with large inertia strong coupling and uncertainty
Optimization of mill performance by using online ball and pulp measurements by b clermont and b de haas synopsis ball mills are usually the largest consumers of energy within a mineral concentrator comminution is responsible for 50 of the total mineral processing cost in today’s global markets expanding mining groups are
Power kw begin opt stop opt figure 2 ball mill grinding circuit the ball mill is in closed circuit with a sump and three cyclone classifiers the ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added the slurry from the ball mill is pumped out of a sump into two cyclone separators the underflow from
The acs can control the load of the mill by the specific algorithm that takes into account the interrelated parameters such as calculating the volume of the coal loading in the mill and the temperature of dustair mixture at the output from the mill measuring of the volume of load of the mills drum is made with the help of vibration analysis by a specific algorithm in real
The automatic control system acs of the ball mills load the acs bm acs is designed to provide centralized monitoring and automatic process control of coal grinding in ball mills at the normal technological process as well as at start and stop conditions routine and emergency of the boilers of the thermal power plants based on
The ball mill has higher circulation load it generates only 30 35 of actual fines you require to be called as product if your product size needed is 100 passing 45 micron then the ball mill total discharge material will contain normally 30 of 45 micron
The ball mill but they can also be used as a onestage grinder the absence of or reduction in the number of balls means they can be less costly to operate than ball mills sag mills of over 40foot diameter have been constructed like the ball mill the agsag mill will have a critical rotation speed above which grinding ceases mill motor
The core technology of this mill is using cone groove mixing and self cleaning the high precision separate loop and cooling system with rotatorstator there is high abrasion proof ally material in milling area to make it process wider viscosity and higher finess material also longer machine
The inmill load volume and slurry solids concentration have significant influence on the ball mill product size and energy expenditure hence better energy efficiency and quality grind can only be achieved with correct tuning of these influential operational factors to the desired optimum
The mill discharge from ball mill 1 will increase with the same water addition to sump 1 the particle size of cyclone 1 overflow will increase this will decrease the ratio and hence the control loop will add more water to keep the ratio constant however the amount of slurry reporting as fresh feed to the second milling circuit will
