Background

Petroleum pitch is the residue of crude oil distillation. According to different extraction degrees, the liquid, semisolid or solid is obtained at normal temperature. The petroleum asphalt has black and glossy color and higher temperature sensitivity. Coal tar pitch is a byproduct of coking, namely, the black matter remaining in the still after distillation of the tar. The temperature change has great influence on the coal tar pitch, and the coal tar pitch is easy to be brittle in winter and soft in summer and has special smell when being heated.

A hammer crusher is a device for crushing materials in an impact mode and is divided into a single rotor mode and a double rotor mode. When the hammer crusher works, the motor drives the rotor to rotate at a high speed, materials uniformly enter a crusher cavity, the high-speed rotary hammer head impacts and cuts and tears the materials to cause the materials to be crushed, meanwhile, the gravity action of the materials enables the materials to impact the inner baffle plate and the screen bars of the frame body from the high-speed rotary hammer head, the lower part of the rotor is provided with a screen plate, the grain fraction smaller than the size of the screen hole in the crushed materials is discharged through the screen plate, and the materials larger than the size of the screen hole are retained on the screen plate to continue to be struck and ground by the hammer. The hammer crusher mainly uses materials with medium hardness, such as limestone, slag, coke, coal and the like with large particle size, which are crushed in industrial departments of cement, chemical industry, electric power, metallurgy and the like, to perform medium crushing or fine crushing operation.

Chinese patent CN 208449468U discloses a pendulum breaker, inside the workstation and from the workstation inside wall upwards pass the workstation and with the drive arrangement of breaker transmission connection and set up the loading attachment at the breaker top, though solved the problem of unable quantitative control broken article, the problem of the required broken size of uncontrollable and broken intracavity residue great problem, nevertheless appear blocking up the stifled car phenomenon easily at the discharge gate.

Chinese patent CN 309124024U the utility model discloses a hammer crusher, which is characterized in that a plurality of grooves are arranged on an arc-shaped crushing plate along the circumferential direction; the top of the hammer head is provided with a convex edge matched with the groove, and the convex edge is arranged in the groove; the cross section of the arc-shaped crushing tunnel is adaptive to that of the hammer head; the utility model has the advantages that: although the problem of adhesion can be solved, if the wet material is easy to cause the sieve pore to be blocked, the material is piled up and the phenomenon of vehicle congestion occurs.

Chinese patent CN 207324964U discloses a utility model, a plum blossom structure with traditional breaker rotor hammer dish changes into disc structure, has improved the dynamic balance nature of rotor, has avoided the impact of former ore to the rotor, has improved the life of rotor, nevertheless causes broken particle size inhomogeneous, blocks up the discharge gate easily, causes stifled car and does not have dust collector in feed inlet department, and the broken a large amount of powders that produce cause dust pollution easily.
