Batch Plant - Paves Singapore

Introduction

Batch mix asphalt plants are the most widespread types of asphalt plant in the world and their popularity lies in the fact that they guarantee top quality and maximum flexibility. The name comes from the fact that the asphalt is produced in batches every 40-50 seconds, depending on the capacity of the plant and the mixing specifications.

Advantages of Batch Plant

Dryer Drum
The dryer drum is nothing other than a rotating cylinder, with a series of flights on the inside which have the function of lifting the virgin material and heating it.

Bag Filter
Due to increasingly restrictive limits for atmospheric emissions together with new technologies for greater filter efficiency, problems related to environmental.

Reselecting screen
Due to increasingly restrictive limits for atmospheric emissions together with new technologies for greater filter efficiency, problems related to environmental.

THE MIXING TOWER

THE MAIN CHARACTERISTIC OF THE BATCH MIX ASPHALT PLANT

Once they are dried, the aggregates reach a temperature of 150-160°C in the dryer and are then transported to the reselecting screen by means of a bucket elevator.

In the vibrating screen, the materials are newly separated by the meshes on the basis of the size required. Once separated, the hot aggregates are fed into the appropriate compartment (4 to 6) and are kept as hot as possible until they are ready to be weighed.

The mixer consists of an armoured hopper, on the inside of which there are two rotating arms with paddles. The counter-rotation of these two arms mixes the aggregates, bitumen and filler until a homogeneous mix is produced.

THE ADVANTAGES OF THE BATCH ASPHALT MIXING PLANT

Consequently, in batch plants (as opposed to continuous plants) the hot aggregates, filler and bitumen are first weighed and then fed into the mixer. After mixing, the asphalt is discharged from the mixer in the storage bin or directly onto the trucks.

Batch plants are therefore a guarantee of maximum flexibility, great versatility and are ideal for urban situations where it is necessary to satisfy a range of different production specifications and to promptly respond to the various needs of the clients.
