A bucket elevator is provided to discharge aggregate into the drying cylinder through the feeding ring.
Drying Cylinder discharges heated aggregate into the storage ring. It is supported on two roller tracks running on nos. guide rollers driven by chain and sprocket wheel. Lifting flights are wear resistant and replaceable.

The discharge end of the drying cylinder is provided with a storage ring fitted with lifting buckets which discharge the hot aggregate into the batching chute.
The batching chute has a fixed volume. Hot aggregate is discharged from chute to paddle mixer by a lever which opens the radial door for discharging the aggregate into the paddle mixer and simultaneously closes a deflector plate at the top of the chute to prevent any material being discharged into the chute while the radial door is open. A thermometer is supplied to register the temperature of the stones in the chute.
A wire rope hoist is provided with lifting frame for easy and convenient loading of bitumen from barrels nto the boiler.
The aggregate and bitumen are mixed in a paddle mixer, fitted with two paddle shafts mounted with arms and tips which rotate in opposite directions. The shafts are gear driven and mounted on lubricated bearings. The paddle tips are replaceable and coated with special hard facing alloy to give them longer life in operation. This arrangement provides positive mixing and gives a homogenous mix, which is discharged through a door at the bottom operated by a lever.
An integral bitumen boiler and bitumen pump is provided for feeding bitumen into the calibrated bitumen bucket for discharge into the pug mill. The quantity of bitumen can be metered through a 3-way cock.
Chimney for drawing out the hot gases is provided which can be folded during transportation.
The whole unit is mounted on a strong chassis of welded and bolted construction with rolled and folded steel sections and provided with four pneumatic tyres. Four strong mechanical parking jacks are fitted.
