Automatic Batch Mix Plant

Endless belt feeder
Shaft-mounted gear motor for minimum maintenance
Individual-frequency control with variable feeding of material monitored and controlled remotely from the control cabin
Speed vibrator motor is operated by a no-flow switch to ensure continuous material flow for the sands the bin
Working platform along hoppers


Dryer Drum

The drum is fitted with a single piece, a hot-formed ring without welded joint (drum tire) on each end, mounted to the drum shell with spring plates
Each drum tire is seated and rolled on two Trunnion rollers
Feeding end of the inclined drum is further guided by 2 guide rollers to limit the axial movement
Special shovel flights are installed to the internal surface along the drum length to transport and form efficient drying curtain to minimize fuel consumption
Special vacuum drum pressure device is fitted to control rotary actuator at the exhaust fan to regulate the air flow
Hot mineral bins and screens are dust-tight enclosed


Burner C/W Blower

Fuel piping system, transfer pump and high-pressure pump are included
Automatic controls for the burner are included to regulate the capacity based on the temperature monitor by a sensor at the drum exhaust gas outlet
Fully automatic, electrical ignition by propane gas
A flame-failure indication that is detected by photocell
Auto start-up of burner system for maximum safety
Fuel Pump and Accessories include
Fuel pump (placed next to the Fuel tank and at ground level)
Piping to the main burner is inclusive of valve and strainer. Pressure-holding valve ensures the line pressure of fuel reaches high-pressure pump of the burner.
From outlet of pressure holding valve, a long flexible hose is connected to the inlet filter of the main burner. Flexible hose ensures fast attachment. Inlet filter is mounted


Hot Mineral Bins

Each compartment is equipped with mechanical overflow chute and sampling pods
Mineral temperature sensors are located inside the sand compartment
Oversize material will flow out via overflow chute to a collection point
Each compartment is equipped with a pneumatically actuated two-stage discharge gates controlled by the computer system.
Each compartment has a maximum level indicator that is wired remotely to the control room to warn the operator when bins are full


Aggregate Weigher

Designed to weigh up to 4 different aggregates
Weigher is fitted with a proper shockproof device to prevent the transmission of vibrations to the load cells
Discharge of the weigher is through two discharge gates that operated pneumatically.


Filler Weigher

Designed to weigh up to 3 different sources
Sealed with neoprene, which is heat resistant in the temperature range of -40 to 150 degree C
Butterfly valves c/w high torque pneumatic actuator, solenoid valves micro switches


Bitumen Weigher

Designed to weigh up to 3 different sources
Bitumen is circulated from the storage tank through 2-way valve, actuated by compressed air
Weigher tank is insulated with Rockwool slabs and heated at the base by thermal oil
Weigher is provided with overfilling protection
Mechanical dial thermometer indicates the bitumen temperature in the tank
Gravity discharge to bitumen spray pipe


Twin-Shaft Pugmill Mixer

Direct gear-motor drive with transmission through the synchronous, helical spur gear
Robust and rugged design to suit hardest site condition.
