Batch Plant VS Drum Plant

 The asphalt batch plant vs drum plant mainly differs in the mixing process of asphalt mixing plant production. According to its asphalt process flow, asphalt mixing plant equipment can be divided into two categories: intermittent forced batch type and continuous drum type. Both have their own advantages and disadvantages. Continuous drum mix asphalt plant equipment is known for its simple structure and good economy. According to the requirements before, the construction of high-grade highways should use forced intermittent batch type asphalt mixing plant equipment and continuous drum type asphalt mixing plant equipment for ordinary road construction.
 

Continuous asphalt mixing equipment is also called drum mix asphalt plant equipment. The technological process is simple and the equipment is also simple. In terms of grading, measuring and heating and drying of cold aggregates, the process is basically similar to that of batch type asphalt mixing plant, but continuous type does not have hot aggregate lifting, screening, secondary metering and other processes. The dynamically metered cold aggregate is directly heated in the drying drum, and then stirred into an asphalt mixture in the mixing drum connected to it. Continuous feeding and discharging. Continuous asphalt drum mix plant equipment will become an inevitable trend in the development of asphalt mixing equipment in the future, and improving its measurement accuracy will promote its rapid development.
 

Batch type asphalt mixing plant equipment is a traditional asphalt mixing equipment developed earlier. It is to add the preliminarily graded cold aggregate into the drying cylinder, after drying and heating, the hot aggregate is then lifted, and then screened by a vibrating screen. It is stored and metered in the hot silo, and added to the mixing pot together with the metered filler (mineral powder) and binder (asphalt). Mix evenly into the asphalt mixture. It measures ingredients, stirs and discharges pot by pot, so it is called intermittent asphalt mixing equipment.
