4.Productivity of rod mill is generally about 15% lower than that of grid ball mill with same specification.When product granularity is smaller than 0.5mm, grinding effect of rod mill is not as good as ball mill with same specification.
To make the milling more efficient, we must first be acquainted with the factors.They are mainly the ball mill structure, the rotation speed, the ball mill media, the lining plate, the material fed and the feeding speed, etc.
The ball mill surface layer subtle panel organization.To shorten the cycle of ball mill produce progress ball mill quality and prolong the life of ball mill,flotation separator directly or indirectly bring social benefit economic benefit uncounted material surface to form the aggrandizement layer will improve his weary function, its reason this layer with a totally different from the matrix in stress condition and organization structure, generally speaking the material handling progress and surface strengthening of the three factors:.
When it is put into use, the materials to be grinded are put into the main frame through the feed-in bin on the side cover.Then ball mill revolves round the vertical axis line by the milling roller hung on the star rack.With the centrifugal force by rotation, milling roller wings outside and presses fast on milling rings to make relieving tool carry materials between milling roller and ring, thus the materials are crushed by the rolling and milling of the milling roller.
2.Observation of the sand return result of the classifier.If the particle size of the material close to the overflow is found to increase, it means that the ball mill steel ball proportion is insufficient, and the ball amount needs to be increased; otherwise, if the coarse particles increase in the return sand, it indicates that the number of big balls is relatively small, it should better add some big balls.
Macsalab drive rolls for rod / ball mills are rubber coated and manufactured in double and triple roll models.The rolls are 120 mm diameter x 1200 mm long and powered by a 0.37 kw 220 volt motor with a variable speed controller.
A ball mill is a grinding device that is used to turn material into fine powder.Ball mills are cylindrical in shape, and are often the grinder of choice when it comes to mashing paints, ores, ceramic materials, and certain hard chemicals.By rotating on a horizontal axis, a ball mill can effectively convert a hard material into a loose powder.
The widespread smasher equipment mostly contains mining crusher, ultrafine mill, winnowing mill, lumber mill, mechanical mill, jet mill and ball milland so forth.
Ball mill machine is mainly composed of feeding part, discharging part, rotary part and driving part which includes reducer, small drive gear, electrical machine and electronic control.inpowder grinding plant, ball grinding process flow includes crushing, milling,air classifying,packing,silos,bucket elevator,conveying,etc.grinded material discharges from outlet grit fluently.Ball grinding mill is formed a closed system with air classifier.Coarse material will be back to ball mill to grind again, and qualified material will go to be packed by worker or packing machine.
Good day sir,thank you very much for your reply sir.Here are the data that you are looking forlargest size of clinker is 60mm , 100% damper openning at mill fan , no hole for fresh air at mill inlet also no hole for water injection.Our ball mill is operated manually not automaticchamber 1chamber 280mm -4tons50mm-5tons70mm-5tons40mm-13tons60mm-9tons30mm-8tons20mm-30 tons.
The balls occupy about 30 to 50 percent of the volume of the ball mill.As the cylindrical shell rotates with the material to be ground, the ball are lifted up on the rising side of the shell and then they cascade down or drop down from near to top of the cell, in doing so, the solid particles in between the balls are ground and reduced in size by impact.The ball mil may be operated in batch or continuous fashion, wet or dry.
Noise insulation materials for ball mills are currently available in the market for noise covers, noise enclosure and noiseproof screens.
