1, according to its structure is different, can be divided into mobile mixing station and fixed type of mixing building.
Mobile mixing stations are suitable for construction sites. 2, according to its operating form is different, can be divided into two categories of periodic and continuous. The periodic feed and discharge system is carried out according to a certain period of cycle. Continuous feed and discharge are carried out continuously.
The periodic formula is commonly used at present.
3, according to its process layout of different forms, can be divided into single-order and two-order type. Single-order The sand, stone, cement and other materials at once to the roof silo, a variety of materials according to the process after weighing, ingredients, stirring, until made into concrete mixer loading and outbound. The mixing building is divided from top to bottom into the silo layer, the weighing layer, the mixing layer and the ground floor.
Single-order-style process is reasonable, high productivity, but the requirements of the factory is high, so the investment is larger, the general mixing building is mostly used in this form. The storage silo and mixing equipment for dual-order materials are generally at the same level. The aggregate is raised to the storage silo, the cumulative weighing and the separate weighing under the storage silo, and then the lifting bucket or belt conveyor is sent to the mixer for stirring. Because the material needs to be improved two times, the production rate is low, but can make the full set of equipment height reduction, disassembly and easy, and can reduce investment, the general mixing station more use this form.
