Asphalt Drum Mix Plant
The Automatic Asphalt Drum Mix Plant consists of
Asphalt Tank
The Bitumen section of CAPIOUS Drum Mix plant mainly consists of Bitumen Tank, Bitumen heating burner, Bitumen Pumping & Metering unit and Hot Oil system.
The Tank is fully insulated to minimize heat losses. The bitumen inside the tank is heated by U-shaped heating tube fitted with automatic burner of adequate capacity. A jacketed Bitumen Pump driven by Variable Speed Motor through Reduction Gear Box is provided to Pump the bitumen to the Drum. The bitumen flow rate is controlled by varying the RPM of Variable speed Motor.
The Bitumen Pump and all bitumen lines to and from the tank except pipe fittings and valves are hot oil jacketed.
An independent electric motor driven pump is used for pumping the hot oil from hot oil tank to the jacketing lines. The single stage burner of bitumen tank is fitted with remote control system to detect flame failure and have electric spark ignition system. The temperature is controlled through thermostatic control device to heat the bitumen in desired temperature range. The main bitumen tank, hot oil tank, blower, hot oil pump, bitumen pump with speed reduction gear box and motors are all mounted on standby chassis and are provided with heavy legs to facilitate erection of the unit.
Mineral Filler Unit
The Filler Hopper is provided to add Filler / Mineral from a separate Hopper, in the mix to the extent pre-selectable in percentage by weight of the maximum plant output.
The unit is fabricated from 5 m thick steel plate and mounted on robust steel structure.
The system is powered by a Variable Speed Motor coupled with Gear Box to Rotary Valve and also synchronized with aggregate & Bitumen output.
The Filler material from this unit is conveyed pneumatically upto mixing zone in the Thermodrum.
Centralized Control Panel
The plant is supplied with centralized Control Panel. All controls, including the motor control center circuit breakers, are provided in the control panel. The control Panel comprises of the Automatic Burner Controls, Aggregate and Asphalt Blending Controls, Motor Controls, Feeder Bin Controls and Electric Switchgear. All the parameters like, temperature of bitumen-hot mix material-exhaust gases and aggregate weight, asphalt percentage, hot mix material weight etc. are displayed on the control panel. It is equipped with protections like Single Phasing, Overload, fuses, Sequence Interlock etc. Load wise data can be printed on the printer provided in the panel. The body of the panel is fabricated from CRC sheet and is duly powder coated.

Load Out Conveyor
Hot Mix material discharged from the Thermodrum is carried by inclined Hot Conveyor belt and discharged into the tipper / truck through Hydraulically operated Surge Storage Hopper.
The Hot Conveyor belt is heat resistant, of reputed make like MRF / Dunlop / Equiv. This belt is supported by number of idlers and The frame is fabricated from appropriate size of channel and angles. A separate AC Motor with Gear Box is provided to run the Conveyor belt. Belt Scraper is provided to avoid any sticking of the mix material to the belt.
Hydraulically operated storage hopper is provided at the discharge end of the conveyor which stores the Hot Mix and allows it to fall as mass in batches and thus avoids segregation and spillage during load out cycle.
