According to the layout process, it is generally divided into one-stage and two-stage. The one-stage refers to the one-time lifting of sand and gravel aggregates, cement, etc. to the top silo of the mixing station, and various materials are from top to bottom according to the production process.
The material is finally discharged from the ground floor, which is mostly seen in the mixing building. Such a mixing station is divided into silo layer, weighing layer, mixing layer, and discharging layer from top to bottom. The mixing efficiency is very high, but the construction is difficult, the demolition is inconvenient, and the investment cost is high. In terms of stage, the mixer is raised again after weighing the aggregate. Although it occupies a large area and the mixing efficiency is slightly lower than that of the first stage, it is convenient to disassemble and assemble, low in manufacturing cost, easy to install, and is widely used, and the improved second stage The production capacity of the mixing plant can be comparable to that of the first-stage mixing plant.
