Components of Asphalt Batch Type Portable Plants : |
| |
DRYING DRUM : |
|
The ANP series asphalt plants are renowned for their high efficiency and low maintenance Drying Drum equipped with field proven flights that give additional amount of drying volumes.
The special drying flight design, a result of the 40+ years experience and R & D, ensures the highest thermal transfer efficiency by allowing specifically designed flights to uniformly transfer the heat by radiation, convection and conduction to all aggregates.

|
|
The aggregate charging is done with charging conveyor belt with seal flange arrangement on dryer drum body to reduce suction of cold air. The drum is equipped with four wheel drive and features a unique dome shaped air preheat arrangement for suction of hot air from outer proximity of dryer drum, that improves thermal efficiency, reduces heat losses, aid power saving, reducing the thermal stresses on the drying drum and noise emissions from the burner.
ANP Plants are supplied with a proven Japanese burner design, reputed for its fuel efficiency and lower emissions. The burner meets the strictest working demands, thanks to its automatic controls and wide turndown ratio. |

BATCHING TOWER : |
The inclined circular motion vibrating screens with patented vibrating screen design, contribute to top notch performance and gives minimum clogging of screen sieves. The free floating screen design prevents vibrations from being transferred to the weighing scales. A accessible wide platform eases the maintenance of the screens.
Hot bin unit is equipped with highly efficient low maintenance pneumatic controls with High and Low level indicators in Control Cabin with system integration allow for automatic controls of the aggregate input from cold feeder bins thus minimizing material loss by wastage.
Highly reliable weighing systems with low maintenance load cells and an easy calibration system makes the ANP series highly popular.
The 3 D mixer unit is the heart of the ANP plant and has a large live zone, realizing a quick and even mixing of asphalt. The mixer unit is hot oil jacketed and supplied with a low-maintenance oil-bath type chain drive.
The paddles, arms and tips are made of wear resistant High Nickel Hardened cast alloy steel. The design of the mixer internals ensures a lower operating cost.
|
|
Hot stone bin sampling trays (optional) and a complete batching tower dust scavenging are standard in all the ANP series plant. |
|
| |
COLD AGGREGATE BIN FEEDERS : |
|
The bins are all-welded and modular in construction, permitting easy addition of bins to meet growing needs. 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. The bins have adjustable calibrated gate openings, 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.

| |
POLLUTION CONTROL UNIT : |
|
The ANP series plants are supplied with a standard dual stage pollution control systems, comprising of a twin cyclonic separators and a secondary bag house filter.
All ANP series plant are supplied with " Freedom", a stage - of - the “- art free air flow type bag house filter unit. Freedom Bag house filters are envied in the industry for their guaranteed savings on power, lower maintenance, trouble free service and strict conformance to stringent environmental norms.
|
Highlights :
|
|
Emission less than 50 mg / Nm³ |
|
Lower Dust loads on bag house filter due to effective removal of coarse dust particles at primary stage |
|
Longer bag filter life, due to reduced dust loads |
|
Zero Maintenance design |
|
Power savings |
|
Filler recycling |
|
|
| |
CONTROL SYSTEM : |

OPTIONALS : |
HOT MIX SILO : |
|
Apollo offers complete range of Hot Mix storage solutions (20-320), to meet plant requirements. Customers can choose from inline surge silo to skip-winch assisted hot mix storage silos. Hot mix storage silo can be offered with options to store different type of mix designs to meet varied site demands.
All the ANP series silos come with state-of-art fully automatic controls with automated safety giving un-interrupted productivity.
|
| |
Savings : |
By opting for a hot mix silo customers gain large benefits: |
|
Achieve increased efficiencies through longer continuous production runs. |
|
Fuel saving - thanks to the uninterrupted and constant dryer drum burner operations.
|
|
Help cater to clients with different mix design requirements. |
|
Reduce the number of mix transporting trucks. |
|
| |
|
| |
BITUMEN HEATING AND STORAGE SOLUTIONS : |
|
With Apollo, customers can opt for direct heating type bitumen storage tanks or indirect heating type hot oil heated bitumen storage tanks. Storage capacity ranges from 15 to 50 tons.
The indirect heating tanks are supplied with a Japanese design thermic oil heater. The direct heating tanks are supplied with automatic imported pressure jet burner. As a standard all Apollo tanks are supplied with auto thermostatic controls and level gauge indicators. |
THERMIC OIL HEATER : |
The ANP series plants are supplied with hot oil jacketing on bitumen pipe line, asphalt pump, bitumen weigh hopper section and pug mill body. Opting for hot oil heating reduces asphalt pump binding, asphalt pipeline blocking, smoother bitumen weigh batcher and smooth pug mill operations.
The thermic oil heaters are supplied with auto temperature control to maintain precise bitumen temperature. The thermic oil heater is supplied with independent automatic control including oil temperature indicator controller, low level switch, low circulation pressure switch, over temperature cut off thermostat burner operating circuits. Capacity range: up to 500,000 KCAL/HR. |
FILLER FEEDING AND STORAGE SOLUTIONS : |
Apollo offers a wide range (4-50 tons) of reclaim and foreign filler storage solutions. The filler from the silo is transported into the filler elevator on the batching tower, which then is weighed & mixed in the pug mill unit.
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.
