Briefly describe the difference between forced intermittent and continuous drum asphalt mixing equipment.

Difference between forced intermittent asphalt mixing equipment and continuous drum asphalt mixing equipment;

Asphalt concrete mixing equipment can be divided into intermittent forced type and continuous drum type according to its asphalt concrete process flow.

Continuous asphalt mixing equipment, also known as drum mixing equipment. The process flow is simple and the equipment is simple. On the reverse side of cold aggregate grading, metering and heating drying, the technological process is basically similar to that of intermittent type, but there is no process of hot aggregate lifting, screening and secondary metering in continuous type. The dynamically metered cold aggregate directly enters the drying drum for heating, and then is stirred into asphalt mixture in the mixing drum connected with it. Continuous feeding and discharging.

Intermittent concrete mixing equipment is a kind of traditional asphalt mixing equipment which developed earlier. It adds the cold aggregate with preliminary gradation into a drying drum, dries and heats it, then lifts the hot aggregate, and then screens it by a vibrating screen. The hot materials are stored and metered, and added to the mixing tank together with the metered filler (mineral powder) and binder (asphalt). Uniformly mixing synthetic asphalt mixture. He measures the ingredients and stirs the materials one by one, so it is called intermittent stirring equipment.
