Asphalt is a dark brown high-viscosity organic liquid composed of hydrocarbons of different molecular weights and non-metallic substances. It has a black surface and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch. Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries as well as paving roads.
Asphalt mixing plant refers to equipment used to produce asphalt in large quantities, and this equipment is generally used in large-scale pouring of cement roads. The asphalt mixing plant can also produce asphalt mixture, modified asphalt mixture, and colored asphalt mixture, which is a necessary equipment for building expressways, graded roads, municipal roads, airports, and ports.
Asphalt mixing equipment is mainly composed of batching system, drying system, combustion system, hot material lifting, vibrating screen, hot material storage bin, weighing and mixing system, asphalt supply system, powder material supply system, dust removal system, finished product silo and control system, etc. Partial composition. Asphalt mixing plant is a very important place for road construction.
