Product Information

A dry lean mix concrete also known as Transit Mix Plant, weighs sand, gravel and cement in weigh batchers via digital or manual scales . All the ingredients then are discharged into a chute which discharges into a truck. Meanwhile, water is either being weighed or volumetrically metered and discharged through the same charging chute into the mixer truck. These ingredients are then mixed for a minimum of 70 to 100 revolutions during transportation to the job site.

Like a mobile concrete plant and a stationary concrete plant, the dry lean mix concrete consists of cement silos, feeding system, control system, weighing system and mixing system. Cement silos are the catching and supply of raw materials such as cement, sand and fly ash as production necessitates. The feed system is a bridge to connect the aggregates and the mixing system. The accuracy of the weighing system determines the amount of mixed materials, and therefore has a great influence on the quality of the mixed concrete. The mixing system only mixes the materials without water. As a result, the mixer truck is important for transporting and mixing concrete. The control system is the core of the whole plant. Workers can reach full automation by using concrete equipment in the control room.

Advantages of dry lean mix concrete
It has higher capacity and lower energy consumption because concrete can be mixed without water
- The cooperation between thedry lean mix concrete and the mixer truck can increase productivity and save time.
- The fresh concrete can be used because of the mixer trucks arrive at the construction site.
- It shortens the construction and enhances productivity.
- It’s got lower power consumption when compared to the wet mix plant.
- Operating costs of dry lean mix concrete are relatively low
- Allows concrete to be mixed more efficiently.
- It could be the short time period of maintenance needed when compared with wet mix plants.
- As in other mixing plants, such as mobile and stationary concrete plants, the dry concrete plant is also automated.
- If the site is quite long, it is an ideal choice for dry lean mix concrete manufacturers. While the mixer truck going to the construction site, it may keep the rotation order to prevent tampering, hardening of the mixed concrete and to ensure the freshness of the materials.
- Dry batch concrete vegetation is much-welcomed modern concrete production equipment that is constantly significantly assist in the development and development of modern roads, bridges and various concrete construction works.
