Bagela Asphalt
Bagela Asphalt Recyclers are manufactured by Bagela Baumaschinen GmbH & Co which is located in Kaltenkirchen, Germany. The company has been in existence for more than 30 years. It has been manufacturing the Bagela Asphalt Recycler for more than 20 years. After over 800 Bagela
Asphalt Recyclers had been produced and sold in the European market, distribution of the Bagela in the North American market was initiated in 2001.
Two main models of the Bagela, the BA7000 and BA10000, yield rated production of seven and ten tons of recycled asphalt per hour respectively. Production varies from rated figures dependent on condition of the asphalt being recycled, its moisture content and the amount of contamination (non-asphaltic material) contained in the asphalt. Under ideal conditions, the rated production can be exceeded.
The Bagela is a portable machine, all models having two axles. The BA7000 can be towed by a 1/2 ton vehicle while the BA10000 requires a 1-1/2 ton vehicle. Machines can be ordered without axles for static mount operation or truck bed mounting.
The basic design of the units involves a rotating drum with internal baffles that tumble the used asphalt through a bath of hot air. The hot air is produced by a diesel fired, twin stage burner at the rear of the drum. The burner introduces the hot air into the drum through a coned opening in the end of the drum. A unique feature of the heating process is that it does not allow the material to come into direct contact with the material being heated. This greatly reduces the potential of overheating the material which can cause it to ignite. It also facilitates the re-melting of the asphalt without driving off the more volatile light hydrocarbons in the asphalt thereby producing an undesirably dry product.
Bagelas are powered by diesel engines and, as before mentioned, employ diesel burners for the heating process. Since no propane is used, the units are very safe to operate. The diesel engines drive a hydraulic pump and an electric generator. The pump powers a hydraulic motor which turns the drum and lifts the charging hopper on the top of the unit. The generator is used in the operation of the burner system.
The recyclers accept both milled and chunk asphalt as input material. The chunk material can be up to a foot or more in diameter. Generally, the larger the model the larger chunks that can be accepted into the throat of the machine. Production using milled material can be slower than chunks if the milled material contains excessive moisture due to being piled outdoors without protection from the elements. Chunk material resists moisture invasion and, therefore, results in higher production.
