Versatility is claimed for Astec’s batching plant range

Astec is introducing its latest generation BG series asphalt batching plant line-up to the market. The prototype BG1800 model has been unveiled, which offers an output of 120tonnes/hour when handling feed materials with moisture content of up to 3%. This features a 2m diameter XL dryer drum, an XL screen with an area of 15m2 and it also has a reverse air baghouse filter with 413m2 of filter area. The plant has an 1,800kg capacity mixer with a 45 second cycle time and the plant can handle up to 40% RAP in the mixer.

The prototype has been built in Astec’s facility in India, but the BG plants will also be manufactured in the firm’s factories in the US for North American customers and Brazil for the Latin American market. The new BG series includes models with outputs of 100-240tonnes/hour and because of the modular design, the plants can be tailored specifically to meet local market requirements. Raji Elmawla, vice president international sales & marketing at Astec said, “We do whatever the customers require and whatever serves the customers.”

Elmawla said, “We will produce them in Brazil and the US also as each market has its own regulations on emissions and recipes. You have to tailor make the products to meet the demands of the local market, but the basic specifications remain the same.”

The machine is designed for ease of maintenance and like other plants in the Astec range, features comparatively few moving parts to lower maintenance needs. Meanwhile the plant also features Astec’s patented V-flights inside the drum, which are made from stainless steel and offer extended working life. The special flights also ensure effective mixing, while lowering energy use. Options include a collar system so that RAP can be added into the drum, while an alternate option is to add RAP into the mixer.

Because of the modular design, the plant is said to be easy to transport and commission. “You only need a small crane to erect it,” said Elmawla.
