Classification of Concrete Mixing Plant

Classification of Concrete Mixing Plant

      Generally speaking, concrete mixing plants are divided into two categories: fixed mixing plants and mobile mixing plants, which are also the first categories that many manufacturers distinguish in their production. Most of the fixed mixing plants are modular and easy to connect, which are mainly used by large commercial concrete manufacturers or concrete component manufacturers, and can be used in large scale construction projects, characterized by high production capacity and stable and anti-interference work. The mobile mixing plant is towed by a trailer unit, which makes the production more flexible and is generally used for various small and medium-sized temporary construction projects, and can be rented out for self-use.

      According to the purpose, it can be divided into commercial concrete mixing plant and engineering concrete mixing plant. The commercial concrete mixing plant is mainly for commercial purpose, which should have high efficiency and economy, and meet the requirements of environmental protection. 

      According to the arrangement process, it is generally divided into one-step and two-step. One-step refers to the one-time lifting of sand, gravel, cement, etc., to the top bin of the mixing plant, and all kinds of materials will be discharged from the bottom according to the production process from top to bottom, which is mostly found in the mixing plant. Such a mixing plant is divided into top-down, silo layer, weighing layer, mixing layer and discharge layer, which has a very high mixing efficiency, but it is difficult to build, inconvenient to demolish and relocate, and has high investment cost. The production capacity of the second-stage mixing plant can be comparable to the first-stage type. 

      According to the number of mixers, the mixing plant can be divided into single-host plant and double-host mixing plant. The model name of double-host mixing plant is 2HZS series concrete mixing plant, such as 2HZS25 concrete mixing plant, which means the theoretical productivity of 2*25m³/h of double-host mixing plant with 2 sets of JS500 mixer. Individual weighing is equipped with a separate weighing unit for each material, and after weighing each material, it is added into the mixer for mixing, which has high accuracy but complicated design and high cost. It is not suitable for large projects. However, the structure design is simple and the cost is cheap.
