As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
Electronic Ear is useful for Control Regulation of Ball Mills using the grinding frequency signal for optimizing the Mill Output It consists of an acoustic signal receiver Microphone Unit Sound Sensor and specially constructed indicating interpreting electronic circuit Control Unit Depending on the height of the material bed the grinding media inside the Ball Mill causes a characteristic noise
Further DetailsDue to measuring the sound directly where it occurs on the mill shell all these disadvantages can be avoided The solution is SmartFill a failsafe highprecision fill level and temperature measurement system for ball mills

Further DetailsWorking Principle Operation The apparent difference in capacities between grinding mills listed as being the same size is due to the fact that there is no uniform method of designating the size of a mill for example a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the
Further DetailsA direct measurement of the ball level in the mill more accurate than power readings as well as a control of it is therefore highly important Load angle as an indicator of milling efficiency Toe and shoulder angles of the charge are always used for liner design purposes
Further Detailsthe control loop will attempt to add water to Cyclone 1 sump to achieve a particle size of 15 300 µm If the hardness of the ore increases the particle size in 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
