Synthetic asphalt production method

Abstract

The invention relates to a synthetic asphalt production method. A synthetic asphalt production machine is used and comprises a fixing frame, fixing vertical plates, a pneumatic screening device and a grinding device, the fixing vertical plates are symmetrically fixed to the left side and the right side of the fixing frame, the pneumatic screening device is arranged in the fixing frame, and the grinding device is installed on the fixing frame. The method can solve the problems that when asphalt raw materials are crushed and ground, ground raw material powder is different in size, powder and fragments are difficult to screen well due to the limitation of the size of meshes in a traditional screening method, thus when the raw materials are used for producing synthetic asphalt, the produced synthetic asphalt is poor in quality, when the synthetic asphalt raw materials are ground and processed, powder or fragments are often adsorbed on grinding equipment, the grinding effect of the grinding equipment is influenced, meanwhile, the number of the raw materials is reduced, and raw material powder also adheres after cleaning equipment works for a period of time.

Description

technical field [0001] The invention relates to the technical field of asphalt production, in particular to a synthetic asphalt production method. Background technique [0002] Bitumen is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It mostly exists in the form of liquid or semi-solid petroleum. The surface is black and soluble in carbon disulfide, carbon tetrachloride. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. In civil engineering, asphalt is a widely used waterproof material and anti-corrosion material. It is mainly used in the waterproofing of roofs, grounds and underground structures, and the anti-corrosion of wood and steel. Asphalt is also widely used as cementing material for pavement structure in road engineering. It can be used in proportion to build asphalt pavement with different structures after it...

Problems solved by technology

[0006] The invention can solve the problem that when the blending method is used to produce synthetic asphalt, the raw materials need to be crushed and ground, and the raw material powders produced by grinding are often of different sizes. When the traditional screening method uses a screen to screen the damaged raw materials , due to the limitation of the mesh size, it is difficult to sieve the powder and fragments well, so that when using this raw material for synthetic asphalt production, the quality of the produced synthetic asphalt will be poor, and the synthetic asphalt raw material During the grinding process, powder or fragments are often adsorbed on the grinding equipment, which will affect the grinding effect of the grinding equipment and reduce the amount of raw materials, and after cleaning the equipment for a period of time, there will be problems such as raw material powder sticking
