Mobility and versatility are key features of some of the latest asphalt plants now being offered. Ease of transport and quicker assembly and commissioning are capabilities seen on new asphalt plants introduced during 2019. The ability to use RAP is another important feature being seen in all of the sophisticated new plants coming to market.

Despite a high output, Benninghoven’s ECO plants can be transported easily
1250 Astec has developed its BG series of batching plants around a modular design concept, with the BG1800 model unveiled at 688 bauma 2019. Featuring an 1,800kg capacity mixer, the BG1800 is designed to be easy to transport and erect, while able to deliver outputs of up to 120tonnes/hour depending on the type of feed and mix required. The BG1800 has a 2m diameter drum and 15m2 of screen area, while its drum is equipped with the firm’s novel stainless steel V-flights, which boost operating life. The full BG range is for plants from 100-240tonnes/hour, with the units able to be equipped to handle up to 40% RAP in the feed, as well as being designed with low maintenance needs.
Modular design helps boost versatility and mobility for Astec's BG1800 plant
Despite being able to produce from 100-320tonnes/hour, 167 Benninghoven’s ECO plants are containerised, making them highly mobile and able to be moved easily from site to site. Users can select from an array of features due to the modular design, with the option to install additional components later on if required. Additional towers can be added if needed and the plants are said to suit use on motorway or airport jobs where large material quantities may be required. Other features include the integrated material loading system.
According to 8591 CMI Roadbuilding, its Magnum Bullet plant, is designed to be assembled and commissioned onsite in very little time. Its versatility is further boosted by the ability to use up to 35% RAP in the feed. The plant can produce up to 150tonnes/hour and features a proven counterflow configuration.
246 Intrame’s Flow Mix continuous plants feature a drier and separate mixer and can use up to 50% RAP in the feed, according to the firm. However, the firm says that its parallel drum plants can use up to 75% RAP in the feed.
Modular design means that customers for Lintec & Linnhoff’s CE3000 plant can select from an array of options. This allows the customer to configure a plant to specific requirements, such as adding the firm’s warm mix system, silo options or recycling circuits. Capacities can range from 200-240tonnes/hour, depending on the type of feed and material being produced.
A retrofit for an Ammann asphalt plant has helped the customer to boost productivity, output and efficiency. The firm, Meier Company, is based in Rotthalmünster in Germany. Prior to the plant upgrade, the facility featured four silos and had a total capacity of 280tonnes.
Günter Papenburg has developed a cooling feature for asphalt plants that it says shortens the time normally needed for a plant’s coal dust-fuelled burners to reach operating temperatures. The cooling technology has been licenced from LOESCHE, a German producer of coal milling systems. GP managing director Carsten Weiss claimed that the firm’s burners consume more of the fuel than rival types, which only burn 90% of the coal dust. “We get an asphalt temperature of 170°C with low emissions and high efficiency
New technology for concrete production will help boost efficiency
New advances in concrete plant technology will help boost materials quality for users. The latest machines are more versatile and more productive than previous generation equipment. Ease of transport and fast assembly/disassembly and commissioning are other important factors for the latest plants.
Research and development is an important issue for all manufacturers in the segment. With Liebherr for example having two new laboratory mixe
Benninghoven has launched a cost-efficient alternating chute unit on its ECO asphalt mixing plant. The type ECO asphalt mixing plant range offers outputs from 100tonnes/hour to 320tonnes/hour to ensure maximum mobility and flexibility. The machines can be operated as stationary plant but the can also handle fast location changes without problems, according to Benninghoven. Benninghoven has always relied on loading skip technology as the link between mixer and loading silo. When working like this, the
