Asphalt concrete plant model BMZ-80, with a capacity of 80 tons of finished asphalt per hour of work. It is delivered in various complete sets, selection of a necessary complete set helps to carry out the sales manager. Description of the work of BMZ-80 When loading the metering hoppers with inert materials (crushed stone and sand), they in certain proportions enter the dryer drum, where they are dried and heated to 160 ° C by heating from the burner. The resulting dust and exhaust gases through a duct system enter the filter unit, where the dust is separated and the exhaust gases are filtered. Separated dust is dosed and used to produce asphalt concrete. After warming up, inert materials through the elevator enter the screen. The screen, in turn, divides the materials into fractions and separates oversized inert materials, which are then disposed of. The hot materials separated by fractions enter the storage bins of the hot inert materials. Each of their fractions is weighed on a weight batcher and in certain proportions (given on the basis of asphalt concrete recipe) get into the mixing drum. Dispensers of mineral powder and bitumen are also installed in front of the mixing drum. Mineral powder from the silo is fed into the dispenser, weighed and sent to the dryer drum. In the same doser, dust is weighed, which is filtered in a filter unit and used as it accumulates in a dust silo. Bitumen is heated to 150 ° C in the bitumen storage, it enters the batcher through the heated line, passes weighing and is pumped to the mixer. Initially, dry materials (crushed stone, sand, mineral powder) are mixed in the mixer, after the bitumen is fed, the final batch takes place, which lasts no more than 20 seconds. Ready asphalt enters from the mixing drum directly into the truck body.
