The return-sand ratio is the ratio of the amount of sand returned by the ball mill to the ore and ore.The effect of graded anti-sand is not only to return the unqualified coarse particles, but also another important role to make the ball mills ore thickening and let the steel ball high efficiency crushing over the entire axial length of the mill increases the productivity of the mill.Under normal circumstances, the amount of sand return should not exceed 500%, and the second section should not exceed 690%.

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:.

Transport belt conveyor transfers the blended raw materials to hammer and ball mills where it is ground.Then the raw materials go through rotary kiln, and cement clinker will be produced.The dry process kiln is shorter than the wet process kiln and is the most fuel-efficient method of cement production available.

Ball mills are industrial crushing tools that are characterized by their use of loose crushing media.Ball mills are just one of many size reduction equipment varieties.Ball mills, along with grinding mills, impact crushers and a variety of other equipment, are used for the reduction of all kinds of materials for all kinds of purposes.

We all know that the main ingredient of limestone is calcium carbonate but sometimes it may also contain magnesium, iron or manganese affecting the whiteness and hardness of limestone.Nowadays, people like to use high-quality limestone to make powder by different crushing machines and ball mills.

Ni-hard iron is specifically used for mixer paddles, augers and dies, liner plates for ball mills, coal chutes, and wire guides for drawing wires.

When the planetary ball mill starts, the motor drives the common sun wheel to move, while the grinding jars, which are located on the sun wheel, turning around its own axis.The direction of the movement of the sun wheel is opposite to that of the grinding jars in the ratio 1:-2.2.The grinding balls in the grinding jars are subjected to superimposed rational movement, the so-called coriolis forces.Under this interaction, the grinding balls release high dynamic energies.The samples are constantly impacted by the grinding balls and rapidly crushed by the friction of the grinding jars inner wall at the same time.

Ball mill maintenance- our shop and field crews make a unique combination to provide complete and up to date ball mill maintenance services.

Ceramic ball mill is the typical grinding equipment which us ball mill ceramics, greatly improves the grinding fineness.Compared with the traditional ball mill, such kind of ball mill has a great advantage in function, structure, and operation.This machine also has great capacity, high technology, and no noise, which plays an important role in the field of metallurgy, building materials, chemicals, industry.

Weight of balls with a heavy charge of balls, there is production of fine product.One can increase the weight of the charge by increasing the number of balls or by using a ball material of high density.Optimum grinding conditions are obtained when the volume of the balls is equal to 50 percent that of the ball mill.So the variation in the weight of balls is done by using materials of different densities.

The iron ore ball mill scientifically adjusts the grading scheme of the steel ball according to the size, and composition of the materials to be ground, so as to make the particle size of the materials more even.
