When to choose the ball mill and when to choose the grinding mill? in the following text, we analyze the structure principle, working mode, applied materials, production capacity, cost and other aspects to show a clear comparation between these two milling machine stars.
Rod ball mill is applied for triturating or crude crushing all kinds of ores with different grades and materials by wet process, especially used for adjusting the .
Small ball mill can be used for grind rock gold ore/ rock tin ore/rock tungsten ore/ rock coltan ore/ rock chrome ore/ rock iron ore and any other type rocks.
The ball mill is one of the necessary equipment for the mine beneficiation plant, and the investment in the ball mill accounted for a large proportion of the entire beneficiation plant.The ball mill balls quality, quantity, and size will all affect the grinding effect of the ball mill.In addition, while grinding the ore block, the steel balls continuously wear and become smaller until it fails, so the grinding balls consumption is extremely large.If the ball mill is loaded with too many grinding balls, the steel balls are easily overlapped with each other, and the grinding effect is lost.Moreover, some of the steel balls are thrown before the height is raised, which reduces the grinding capacity as a whole and increases the power of the ball mill.If the ball mill contains too few balls and there is not enough capacity between the steel balls to grind the material, it will prolong the working time of the ball mill, which will not only consume a lot of energy, but also cause low grinding efficiency.Therefore, the rationality of ball mill ball loading very important.
It is indispensable lubricating the ball mill in its regular operation.Utilizing decent lubricating essential oil facilitates decrease possibilities of losses and unexpected halt, which advantages the individual a lot.We will briefly introduce equipment digesting lubricating essential oil since the follows:.
It is generally acknowledged by the industry insiders that at the peak moment of real estate, wholesale building concrete is needed, sand washing equipment and considering the full use of energy source and environmental protection, it is really very troublesome.While the application of aerated concrete relieves this condition, for the raw material of this comes from coal ash, sand dust, coal gangue, and waste residue.Ball mill is not only the indispensable production facility in cement, mine, metallurgy and ceramics, but also the fine grinding machinery in industrial production.
The balls impact on the milled material longer at the pipe ball mills.The drum of these mills lined with flint blocks inside or flint pebbles on the cement.Material continuously fed by the drum axis through a hopper at one end and leaves at the opposite end of the drum through end wall or holes on drum walls.Pipe ball mill (pic.3) provided with a drive with construction similar to the drive of rolling mills.The central drive shaft has milled protrusions and depressions at the ends and enters them into the corresponding coupling.In this arrangement the axial displacement of the mill is not transmitted to the reducer or motor.
Ball mills are normally applied to grind material 14inch and finer, down for the particle dimension of twenty to seventy five microns.Toachieve a sensible effectiveness with ball mills, they must be operatedin a shut method, with oversize continuously being recalculated backto the mill to become decreased.
Another key factor in choosing a rod machine over a ball type press is void space.You ideally want as little open space as possible so you have more grinding contact between the rods and the ore.Ball mills need more open space so the balls inside can cascade and grind but this space lessens the contact between metal and ore per surface area.Again, depending on the site project media rods won't necessarily always be the better option but if you are concerned about void space in your grinding process a rod machine may be the right choice.
Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.
