Asphalt Drum Mix Plant
An asphalt plant is also known as asphalt drum mix plant, hot mix plant, continuous asphalt type plant, parallel flow type etc.
Asphalt plant works on the principle of mixing aggregate with bitumen/asphalt at a certain temperature to give a proper mix for paving.
The range of COMIX ASPHALT DRUM MIX PLANT Starts from 20TPH to 150TPH, available in both mobile and stationary models.
An Asphalt Plant is an intelligent assembly of mechanical and electronic equipment where aggregates & minerals are blended, dried, heated, and mixed with asphalt to produce hot mix asphalt (HMA) meeting specified requirements of road building.
The Asphalt Plant is made up of high-quality steel & rugged design to give high performance for a long time without compromising on the quality of produce/mix with high fuel efficiency, Hence enchasing the profit earning of the customers.
The Asphalt Plant Consist of:
- Cold Aggregate Four-Bin Feeder
- Single Deck Vibratory Screen for oversized material removal
- Slinger (Cold) Conveyor
- Dryer Auto Burner
- Drying Cum Mixing Thermo drum with Dust Collector
- Load out conveyor with Gob hopper
- Asphalt Tank
- Mineral Filler Unit
- Centralized Control Panel with insulated Cabin
- Fuel Storage Tank
- Fuel Storage Tank
Four Bin Feeder
The bins are all – welded and modular in construction, permitting easy addition of bins to meet growing needs. A free flow of aggregates is ensured with steep bin walls and valley angles without hold up of materials in the corners. The bins supplied with adjustable calibrated gate openings and variable speed feeders drive, together offers total proportional control, greater flexibility and accuracy of operations. This ensures top performance even under the toughest of operating conditions. Each bin having independent belt driven by AC variable speed motors, with a single load cell for weighing of aggregate as per job mix formula. At the discharge end of gathering conveyor a single deck vibratory screen is provided for oversize removal of aggregate. Sand bin is equipped with vibratory motors.
Burner
The burner is electronically fired fully automatic & two stage (High & Low) pressure jet type system, It is suitable to use LDO / Diesel as fuel, It is fitted with photocell to detect flame failure The Burner have electric spark ignition system. Sequence controller for regulating burner operation. The high pressure atomized, fully automatic remotely controlled burner unit has already gained an enviable reputation for its fuel efficiency, ease of operation and high uptime. Completely automatic process control with systems interlocks ensure conformance to high safety standards.
Parallel flow Drier Drum (Thermodrum)
The Drier drum is fully insulated. An automatic electronic type burner is positioned in such a way that the flame direction makes a counter flow situation for aggregate temperature Control in different seasons. Optimum utilization of fuel. The Drying and Mixing unit of the asphalt plant demands complex flight design and heat transfer technology. The latest design up-gradations; Comix thermo drum is miles ahead of competition. The thermo drum unit follows a triple heat transfer system by conduction, convection & radiation technologies ensuring transfer of heat to the aggregates, translating into higher productivity and lower fuel consumption. The unique flight design ensures total heat transfer, a thorough mixing & coating, lower emissions and prevention of bitumen oxidation.
Slinger Conveyor
Single deck vibratory screen is fitted at the end of gathering conveyor for removal of oversized material provided in 4 sizes, Separate detachable slinger conveyor is provided to transfer the aggregates received from the vibratory screen to feed into the Drier drum. The feedback from the Load cell (at gathering conveyor) is processed by the PLC, which further automatically controls and processes the bitumen and filler proportioning.
Bitumen Tank
The tank is fully insulated to minimize heat loss. The bitumen inside the tank is heated by W-shaped heating tube fitted with automatic burner A jacketed bitumen pump driven by variable speed motor, the bitumen flow rate is controlled by varying the RPM of variable speed motor. Bitumen lines to and from the tank except pipe fittings and valves are hot oil jacketed. customers can opt for a direct heating type or hot oil heated bitumen storage tanks. Storage capacities range from 15-50 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 tanks are supplied with auto thermostatic controls and level indictors. The fully automatic PLC control ensures a precise metering of bitumen into the thermo drum.
LDO Tank
Different capacity of LDO tank is provided with the plant according to their production capacity Suitable pumping station and necessary fittings for Dryer & asphalt tank burner.
Mineral Filler Unit
This unit is meant for adding fine filler in the mix. Mineral is supplied as per the required percentage to the mixing drum unit through screw conveyor driven by AC variable speed controls. Dust or filler feeding into the hopper by pneumatically. A wide range is available for filler storage and feeding for the customers to choose from, depending on the site requirements. A variable speed computerized synchronized metering systems ensures the right proportioning in the mix.
Control Cabin
Air condition fully insulated Control Cabin with all Standard Accessories is provided with the asphalt plant.
Control Panel
Fully automatic PLC base HMI Control Panel, Built on proven technology, fault detection and solution, Components from Siemens, Delta & L& T.
Storage Silo
Fully insulated storage silo with hydraulic power pack to regulate the flow of mix material is provided with the plant. A complete range of customized solutions for asphalt storage is also available, the standard range includes MONOPAK and TWINPAK systems. MONOPAK silo are available with storage capacity from 10 to 80 Tons. The TWINPAK silos are available with storage capacity ranging from 50 to 80 Tons with an additional feature of storing different mix designs. Storage combinations can be availed by opting for customized MULTIPAK designs. The silos are supplied with automated standard safety controls and a process interlocks. The storage silo is swivelling with load-out conveyor.
Pollution Control Unit
Pollution control Unit consist of multi-cyclone dust collectors, Wet dust type venturi collectors and fil These are standard options available as per International Standards with Lowest Power Consumpis Based on free air flow system. Dissolve all hazards soluble gases.
