Description

There is the raw material crushing system of blowing function
Technical field
The utility model relates to a kind of system, especially relates to a kind of raw material crushing system with blowing function, belongs to bio-mechanical field.
Background technology
Pulverizing is that solid material is applied to external force, makes it be split into the particle that size is less, a kind of unit operations that belongs to powder technology.The solid material that Chemical Manufacture is used and coal, often need be crushed to certain particle diameter could use.For example, have in the chemical reaction process of solid particle participation at great majority, reduce grain diameter, can increase phase border contact surface, improve reaction rate.In leaching operation, reduce particle diameter and both can increase phase border contact surface, can shorten again material in intragranular diffusion length, improve leaching speed.In the production processes such as pottery, cement, pigment, catalyst, for obtaining uniform solid mixture, first various raw materials are worn into fine powder.Some chemical products, must be crushed to certain particle size, just can conform with user's needs.Visible pulverizing tool in Chemical Manufacture has been widely used.Press material particle diameter after crushed, pulverize and be divided into again broken and grind.Fragmentation is that lump material is become to granular material, and grinding is that granular material is become to granular material.Comminution ratio claims again degree of grinding, in order to measure the effect of crushing operation.Comminution ratio i is defined as: in i=D/d formula, D and d are respectively the particle diameter of material before and after pulverizing.Comminution ratio can reflect the result of single-set operation, also can reflect the change of size of material after whole crushing system.
Material is subject to External Force Acting and the mechanism pulverized is complicated, there is no so far blanket theory.About the energy consumption of crushing operation, there are following three kinds of basic hypothesis: surface area hypothesis, within 1876, P.R. Lei Tingge proposes, and the surface area newly increasing after pulverizing required energy and pulverizing is directly proportional; Volume hypothesis, F. base gram proposition in 1885, pulverizes required energy and is directly proportional to the logarithm of comminution ratio; Crack hypothesis, nineteen fifty-two F.C. Bond proposes, and the square root of pulverizing required energy and particle diameter is inversely proportional to, and above-mentioned various hypothesis are all to investigate required energy by the variation of particle diameter before and after crushing material, and do not consider motion and the energy transmission of material in crushing process therefore have limitation.The a large amount of mechanical energy of crushing operation consumption, therefore must follow the principle of " not doing excessive pulverizing ", according to factors such as the character of material, shape, particle diameter, comminution ratio and production scales, adopt dry method or wet method operation, suitable circuit grinding, mode of operation and plant equipment are selected in design.Because material has gravity, in the time pulverizing, there is the material of part easily to occur the phenomenon of deposition, or even be bonded in device interior, cause the particle of pulverizing inhomogeneous, cleaning not in time, causes follow-up raw material to pulverize rotten.
