Asphalt Batch Mix Plant

The bins are all-welded and modular in construction, Steep bin walls and the valley angles allow free flow of aggregates from the feeders minimizing hold up of materials in the corners and bridging with sticky aggregates, adjustable skirts are provided to prevent leakage between bin bottom and belt surface. The bins have adjustable calibrated gate openings, bins are provided with feeding units comprising of head and tail pulleys, single roll idlers, endless rubber conveyor, screw type belt tensioners, replaceable rubber skirting no flow indicators in control panel for operator acknowledgements and variable speed feeder drives together offer a total proportional control, greater flexibility and accuracy of operations. long belt feeders with an adjustable radial discharge gate.

With rated feeding capacity with squirrel cage electric motor and speed reduction unit & is Supplied with trough idlers, roller guides, return rollers and screw-type belt tensioners.

Automatic accumulating, weighing type Aggregate weigh hopper, with four point suspension hopper and load cell transducer. Automatic individual weighing type Asphalt and Filler weigh hopper with four points suspension hopper and load cell transducer. All weighing hoppers are fitted with proper shock isolation device. Aggregate weigh hopper, Filler weigh hopper& Asphalt weigh hopper are there.

Totally enclosed, vertically mounted, centrifugal discharge type bucket elevator having heavy duty K type chain and toothed sprocket at drive ensures smooth operations of entire elevator system. Eliminating unbalancing of buckets during heavy loads when plant is operated at full capacity. Toothed sprocket chain drive with fully covered box for easy installation on tower container frame. The hot bucket elevator is a totally enclosed chain driven system. Bucket tips are double reinforced for maximum durability. The elevator unit is electrically driven directly by gear motor eliminating chain drive mechanism having higher maintenance. AASPA bucket elevators are designed for long service life and easy maintenance access. Super-tough wear materials and a special entry chute design make bucket elevators superior performers.

Completely enclosed Vertically mounted Filler elevator with induction discharge type bucket elevator for feeding filler into filler storage bin on the mixing tower are there. Filler and dust storage bin is provided with a level indicator to control the filler supply from filler elevator automatically. A Rotary type filler feeder with pneumatically operated seal gate, feeds filler from filler storage bin into filler weigh hopper. Dust Fliller Filling & Storage Filler receiving from ground level (with suitable storage capacity) to silo by pneumatically or through bucket elevator control with level sensor. Silo with vibratory motor, filler receives dust from filter bag house through auto control screw conveyor into receiving hopper of bucket elevator. The filler from silos can optionally be supplied with filler feeding bucket elevator to suit bagged filler feeding. As a standard the filler silo are supplied with level indicators and process interlocks.

Primary pollution control is a dry dust collection type. The dust is collected by the dry dust collectors from three points: drying drum, vibrating screen and the hot bins ensuring that proper dust free aggregates enter the mixing drum. Primary dust collection system in form of a Double Cyclone is provided to entrap larger dust particle from the dryer drum exhaust and for scavenging for the batching tower. Reclaimed dust recycling conveying system comprising of a material seal damper at the bottom of the cyclones, feeding the reclaimed dust at the foot of the hot elevator. High capacity Exhaust fan powered by heavy duty motor with automatic damper controls are provided.

Jacketed, gear type Asphalt transfer pump is provided for feeding asphalt from the storage tank to the asphalt weigh hopper. A Bitumen weighing hopper is at the bottom which is hot oil heated and mounted onto three electronic load cells. By heated, & well dimensioned feeding pipe, Bitumen gets distributed via gravity into mixer within seconds. Which guarantee Homogeneous distribution in mixer.

Customers can opt for direct heating type bitumen storage tanks or indirect heating type hot oil heated bitumen storage tanks. Storage capacity ranges up to 50 tons. The indirect heating tanks are supplied with a superior design thermic oil heater. The direct heating tanks are supplied with automatic imported pressure jet burner. As a standard all our tanks are supplied with auto thermostatic controls and level & gauge indicators. Bitumen jacketed piping with process valves and fittings for manual tank selection and single bitumen delivery pipeline are given.

The thermic oil heaters are supplied with auto temperature control to maintain precise bitumen temperature, independent automatic control including oil temperature indicator controller, low level switch, low circulation pressure switch, over temperature cut off thermostat burner operating circuits.
