Asphalt mixing equipment is a must in the highway construction industry of construction machinery, is a complex electromechanical integration equipment, cold material supply system, heating and drying system, aggregate thermal screen system, thermal systems, powder systems, asphalt systems, mixing system, production system, composed of dust removal systems, pneumatic systems, and control systems. Cold material supply system, and heating drying system, and hot material screening system main of role is in control system of role Xia will raw materials by must than column for heating screening Hou store; hot aggregate system, powder material system, and asphalt system main of role is in control system of role down weighing, and conveying asphalt mixed material production by need of various raw materials; mixing system of role is mixing has by must proportion mixed of various raw materials;

Production system is down and the control system transportation, storage of asphalt mixture; is part of the control system of the pneumatic system units, such as feeding, unloading door switch, etc. The entire production process cold supply, heating, screening and weighing, conveying, feeding, mixing and unloading are controlled by the control system automatically. Obviously, it is a complex subject to multi-link system. Mixing performance of asphalt mixing equipment, material dynamic proportion, materials weighing accuracy directly affect the mixture.
