Crushing Action of Ball Mills. ... A ball mill has a certain definite maximum power rating depending upon its ball load. Multiplying the kw.hours per ton by the tons required to be crushed per hour, the product will represent the power required, and the mill nearest to that power rating should be selected. Fig. 4 is a preliminary power curve ...
Since there are not that many small SAG mill operations of under 2000 TPD, and most sub2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <″ (40 mm) and often as finely crushed as <3/8″ (9 mm).
A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls. The drive system can either consist of a central drive (central gear ...
In this technical article electrical systems in cement plant will be touched upon. All machines are driven by electric motors. Majority of the motors are 400 440 volts. A selected few motors of higher ratings are MV motors with 3300, or 6600 or 11000 volts. Most motors are fixed speed and unidirectional motors.
Ball Mill can accept a feed size of 12mm or less and deliver appropriate size in the range of 50m. The speed of Ball Mill varies between 60 to 70 As the product size become fines, the capacity of a mill reduces the energy requirement increases. The power consumption of a ball mill is in the range of to 10 kwh/ton.
