Ion is usually set between 4-20/minute, if the speed too great, may create centrifuge force thus the grinding balls stay with the mill perimeter and dont fall.In summary, it depends on the mill diameter, the larger the diameter, the slower the rotation (the suitable rotation speed adjusted before delivery).What is critical speed of ball mill? the critical speed of the ball mill is the speed at which the centrifugal force is equal to the gravity on the inner surface of the mill so that no ball falls from its position onto the mill shell.Ball mill machines usually operates at 65-75% of critical speed.What is the ball mill price? there are many factors affects the ball mill cost, for quicker quotations, kindly let me know the following basic information.(1) application, what is the grinding material? (2) required capacity, feeding and discharge size (3) dry or wet grinding (4) single machine or complete processing plant, etc.

\ critical speed_ when the ball mill cylinder is rotated, there is no relative slip between the grinding medium and the cylinder wall, and it just starts to run in a state of rotation with the cylinder of the mill.This instantaneous speed of the mill is as follows: n0 - mill working speed, r/min; kb speed ratio, %.There are many layers of grinding media in the mill barrel.It is assumed that the media will be concentrated in one layer, called the polycondensation layer, so that the grinding media of this layer will be in the maximum drop, i.E.The calculating speed of the mill when the total impact energy is the largest nj.Therefore, it is theoretically deduced that the reasonable working speed is the working speeds of various mills are shown in table 1-10.Table 1-10 working speeds of various mills.
Heidelbergcement have officially inaugurated a new cement mill at their plant in bangladeshs seaport city of chittagong.The ball mill has a grinding capacity of about 0.8 million tonnes per annum and represents an investment of around us$16 million.
Ball millmain features and benefits1.The machine is made up of feeding part, discharging part, gyre part, transmission part (reducer, small transmission gear, motor, and electrical controller) and so on.2.The hollow axis adopts the cast steel and the lining can be replaced.The big rotary gear is forged from cast rolling gears.3.The barrel body is inlaid with wearable plates.4.The machine runs steadily and efficiently.
There are many weak magnetic ores that are bulk and need to be crushed first, crushing, grinding then magnetic separation.The general process flow is ore analysis, jaw crusher, screen, roller crusher, ball mill, magnetic separation.
Even for solid fuel grinding, there has been a minor trend back to ball mills.This is most evident for petcoke grinding, where the demand for very low residues, and the very hard and sometimes abrasive nature of high-sulphur cokes has resulted in ball mill selection.
Sample requirements: a minimum of 8 kg of material crushed to nominally minus 10 mm is preferred.Jktech would stage crush the sample to minus 3.35 mm, as required for the bond ball mill work index test feed.When a jk drop weight test is also being carried out, sufficient sample should be available from the jk drop weight test residue.
