add to favorites	Marble Gangue Crushing Industry	Cars
Marble gangue is a kind of solid waste discharged from marble mining and marble washing. It is a kind of black-gray rock with lower carbon content and harder than marble. In real life, if the gangue has not been treated by crusher and other equipment, it will seriously damage the environment. From the point of view of marble mining process, China produces 100 million tons of marble annually and discharges about 14 million tons of gangue. From the point of view of marble washing and processing, 20 million tons of gangue will be discharged per 100 million tons of coking marble washed, and 15 million tons of gangue will be discharged per 100 million tons of power marble washed. From these data, we can see that the discharge of marble is huge. A large number of piled marble not only occupies land and affects the ecological environment, but also pollutes the surrounding soil and groundwater by leaching water of marble. Marble gangue contains certain combustibles, which occurs naturally under suitable conditions and pollutes the atmosphere by discharging harmful gases, affecting the health of residents in mining areas. Therefore, the treatment of marble is imperative.

The working principle of ball mill is that the motor drives the cylinder to rotate through the deceleration device. When the cylinder is rotated, the crushed ore and steel balls are brought to a certain height by the friction force and centrifugal force of the lining plate. As a result of gravity, the ore will be thrown down and dropped, and the ore will be gradually crushed under the impact and grinding action. The crushed ore is discharged out of the barrel through the discharging part. After the discharged minerals are classified into qualified products in the screw classifier, the coarse sand is returned to the ball mill through the combined feeder to continue grinding. The feeder feeds continuously and evenly, the ore enters the ball mill continuously and evenly through the combined feeder, and the grinded materials are discharged continuously from the ball mill. Ball mill is a continuous grinding equipment which can work 24 hours a day.

For example, nowadays cement is produced by a new dry process with pre-decomposition, which improves the silicic acid rate in the raw material mixing, and often needs to be mixed with siliceous raw materials. The contact between the jaw plate and the jaw crusher surface is not stable; the eccentric shaft rotates too fast to remove the crushed materials, which results in jamming of the crushing chamber and wear of the jaw plate. Material properties have changed, but the crusher has not been adjusted in time; the angle between the movable jaw plate and the fixed jaw plate is too large to exceed the normal range; The strength and wear resistance of the jaw plate are not good. The newly installed jaw plate must be fixed tightly, installed well, and the surface of the jaw crusher contacts smoothly. A layer of material with good plasticity can be padded between the jaw plate and the surface of the jaw crusher. Every batch of materials entering the crusher should be sampled and checked. Once there is a great change in the nature of the materials, the parameters of the crusher should be changed in time to match the materials entering the crusher.

add to favorites	Physical Properties of Stone Materials	Cars
(1) The brittleness, the brittleness of material has great influence on the function of sand making machine. The material before and after sand making machine does not change or change little is called brittle material. The material is called plastic material when the sander first deforms and then breaks. Brittleness is proportional to the difficulty of sand - making machine. (2) Friability - fragility refers to the specific power consumption of a material from a certain granularity machine to another specific dimension under certain conditions. Because the process of sand making machine is affected by many factors, it is impossible to use strength, brittleness and hardness to comprehensively represent the difficulty of the material making machine, so there are many ways to express the material vulnerability. Currently, the bond performance index is widely recognized. It should be pointed out that the physical properties of materials are not uniform. The binding force between different materials is less than that of the same material. The binding force of the same material surface is smaller than that of the material interior. Generally speaking, the smaller the material particle size is, the less effective the material strength is. As the strength of materials increases, sand making machines are difficult to make materials.
