Rapid International Launch New Continuous Mixing Plant In USA

Fully Weighed Continuous Mixing PlantThe Rapidmix400CW is the new generation of this highly acclaimed continuous mixing plant range and North American customers and Dealers alike were eager to see the new model arrive.

The Rapidmix continuous mixing plant is now offering full weighing options for all materials - aggregates, cement and water. Measurement by weight is a critical requirement of specifications and the Rapidmix400CW offers record keeping that is automated, precise and detailed.

The new Rapidmix400CW model now incorporates a 1200mm belt conveyor between the aggregate hopper and the continuous mixing chamber. The weighing belt is supported on load cells and this measures the weight allowing the feed rate of the aggregate to be determined. The new plant also incorporates a cement weigh system, using a rotary valve feeding a weighed screw with twin outlets for discharging into the mixer. The water is monitored through using a flow meter.

The first customer to take delivery of the new model was Rollcon LLC, located in Houston Texas. Rollcon is a premier contractor that specialises in providing quality roller compacted concrete (RCC) paving solutions for both public sector and private industry clients. Rollcon worked with Rapid USA Inc to first demonstrate the new machine, which has now been put into action on the latest phase of the Port of Houston development, producing up to 400 tonnes of material per hour.

Rollcon LLC decided on the new Rapidmix400CW after successful use of its predecessor, the Rapidmix 400C continuous mixing plant, on previous projects. Rollcon has confidence the Rapidmix mobile continuous mixing plant is key to ensuring that Roller Compacted Concrete (RCC) projects are carried out on time and within budget. It provides the mixing efficiency needed to evenly disperse the relatively small amount of water used in the mixing of RCC. Dump trucks then transport the RCC and discharge it into a paving plant, which places the material in layers typically up to 10 inches (250 mm) thick and 42 feet (13m) wide.

Port paving is really suited to Roller Compacted Concrete, due to its superb strength. It is capable of standing up to massive loads and specialised equipment. The machine can work on a variety of applications such as bentonite landfill sealing, dam construction, contaminated soil stabilisation as well as cement treated base for road construction.
