Asphalt concrete mixing equipment is one of the key equipment for asphalt pavement construction, and its performance directly affects the quality of the paved asphalt pavement. The function of the asphalt concrete mixing equipment is that the aggregates and fillers of different particle sizes are blended together in a prescribed ratio, using asphalt as a binder, and mixed into a uniform mixture at a prescribed temperature.
The fastest mixing process can only occur when the quality of the mixture circulates vertically and horizontally along the shell of the agitator, the mixture moves strongly vertically (mixture boiling effect), and the asphalt sprays the mixture. The speed at which the components are evenly distributed along the volume of each feed depends on the choice of the installation angle of the rotating shaft for the blades to ensure the high-speed circulation of the mixture along the longitudinal and horizontal directions of the mixer body.
1. Regardless of the type of asphalt concrete mixing equipment, its production capacity is affected by factors such as the variety and requirements of the finished material, the moisture content of the mineral material, the climatic conditions and the degree of completion of the equipment. Therefore, in addition to ensuring that the equipment is intact during the operation of the mixing equipment, it is also necessary to cultivate an ore material moisture content detector and a finished material analysis analyzer, etc., and often check relevant data for the operator to adjust the operation in time to keep the equipment in the most Work in good condition.
2. Make full preparations before the operation, and carefully check whether all working parts and devices of the mixing equipment are intact and normal. If there is a problem, it must be properly handled before operation, and avoid running with disease.
3. The operation must strictly follow the procedures and precautions specified in the equipment instruction manual. After the ignition is normal, it should be monitored whether the dust collector is working properly to ensure that the drying drum is burning under normal negative pressure. After production begins, it should be monitored whether the hot aggregate elevator and mixer are working properly to coordinate the operation of other working parts.
4. Fully understand the mixing system, put forward the general flow of mixer design, and describe the performance analysis methods of intermittent forced asphalt concrete mixing equipment and continuous drum asphalt concrete mixing equipment.
5. Perform mechanical analysis on the intermittent forced asphalt concrete mixing equipment, determine the main parameters of the intermittent forced asphalt concrete mixing equipment, and design the double horizontal shaft mixer structure.
6. The designed mixer can make the old asphalt concrete removed from the road section be recycled.
The current large and medium-sized asphalt concrete mixing equipment is mostly driven by motor, which can obtain a large mixing capacity, which is beneficial to improve the production stability of the mixer.
