Mixing system is to mix Well-measured gravel raw materials such as gravel, cement, water, and admixtures in a mixer, to form the final concrete with specified strength . Because the mixing ratio of the concrete is designed to fill the gap between the fine aggregate and the coarse aggregate. and the cement colloid is evenly distributed on the surface of the coarse and fine aggregate. Therefore, the most compact concrete can be obtained by mixing materials evenly.
The system is to mix the raw materials such as sand, cement, water, admixture and other raw materials in the mixer evenly, forming the finished concrete that reaches the specified strength. Because the design of concrete mixture ratio is just to fill the gap of coarse aggregate according to the fine aggregate, and the cement colloid is evenly distributed on the surface of coarse and fine aggregate, so only by mixing the mixture evenly can we get the most dense concrete in concrete batching plant.
Camelway JS twin shaft concrete mixer researched and developed based on the research results of fluid mechanics and tribology, the mixing arm and mixing blade are streamlined shape, this unique structural design can realize the axial direction of the mixture, and the interlacing and circulating flow of the mixture, for achieving well mixing effect and high efficiency. It consists of transmission device, seal of end-shaft, cylinder and liner components, lubricating device, loam cake and water distribution device, unloading system and mixing device. As shown in the figure:
The mixing mechanism is the core partof the mixer, the quality of concrete mixing, the productivity, and maintenance costs are all related to the mixer. The main function of the mixing mechanism is to mix the granel, aggregate, cement, water, additive, admixture and other materials into homogeneous concrete in the mixer. This concrete has good construction performance (workability).
The layout principle of mixing blades:
1.Make the material flow reasonably in the mixer cylinder, and mix the material into the homogeneous concrete in the short batching time.
2.During the rotation of the mixing shaft, try to make the number of mixing blades involved in the mixing, so as to achieve mixing uniformly and reducing impact.
3.Make the material evenly distributed in the mixing cylinder, do not accumulate in local sections of the cylinder, avoid damage to individual blades and mixing arms due to overload.
Camelway JS twin shaft concrete mixer researched and developed based on the above principles. As shown in the figure above, the material is driven by the mixing blades and forms a large cycle in the cylinder, between the two shafts, the mixing blades on the left shaft pile the material to the right, and the blades on the right side will pile the material to the left. A small circulation of material between two shafts. The material accumulation between the two shafts is high, and the material rolling down along the slope, and participates in the circulation of the materials. Thus, the mixing motion of the mixer is very intense, high-qualified concrete can be mixed in a very short time.
