According to modern production technology, concrete can be divided into ready-mixed concrete (RMC) and precast concrete. Both are industrialized automatic batching production, which is fundamentally different from the traditional on-site manual preparation of concrete.
When it comes to ready-mixed concrete and precast concrete, it is simple to distinguish them. commercial concrete is a semi-finished product, and precast concrete is a finished product. Commercial concrete, also known as ready-mixed concrete.
The ready mixed concrete is got by mixing cement, aggregate, water, admixtures, mineral admixtures evenly in a certain proportion and then is transported to the construction sites within a specified time. Precast concrete is poured and cured in the factory rather than at the final construction site (such as concrete precast parts, concrete blocks, etc.)
Ready Mixed Concrete Plant
The
ready mixed concrete plant is a combined device used to mix concrete in a centralized manner, which is mainly composed of 5 major systems including the mixing host, material weighing system, material conveying system, material storage system and control system. Among them, the concrete mixer is a key part. The twin shaft concrete mixer is the mainstream concrete mixer used in RMC plant.
Advantages of twin shaft concrete mixer
1. It has strong mixing ability, uniform mixing quality and high productivity.
2. It can achieve good mixing effect for concrete with dry hardness, semi-dry hardness, plasticity and various proportions.
3. The mixing shaft of the main mixer adopts anti-adhesion technology to effectively prevent cement from agglomerating on the shaft. The shaft end seal adopts a unique multiple sealing structure to effectively prevent slurry leakage and ensure the continuous and long-term operation of the entire mixing system.
4. The cleaning system adopts high-pressure water pump automatic control and manual control, and each water outlet is located directly above the mixing spindle, which improves the efficiency of mixing, increases water mist, reduces dust pollution and effectively removes cement agglomeration.
Precast concrete mixing plant
Precast concrete is the main material of concrete precast parts, and good-performance production equipment is the foundation. It usually choose planetary concrete mixer.
Advantages of planetary mixer
1. The vertical shaft planetary reducer is specially designed and developed, ensuring a omni-directional mixing, even mixing effect and no dead corner.
2. The main engine is reliable and wear-resistant, the mixing is fast and uniform, the working life of the mixing shovel is no less than 30,000 batches, and the life of the liner is no less than 50,000 batches.
3. Multiple discharge ports can be designed, and the discharge door can be opened manually. In the event of a sudden failure or temporary power failure, the material can be manually shoveled out of the discharge port.
4. The mixing host has the ability to instantaneously overload 10%.
5. There is an interlocking device between the inspection cover and the opening and closing power supply. When the inspection cover is opened, the power supply is cut off, and the supporting host cannot be used.
