1, according to its different structure, can be divided into mobile mixing station and fixed mixing building。Construction site for mobile mixing plant。
2, according to its different forms of operation, can be divided into periodic and continuous two categories。The cyclic feeding and discharging system is carried out in a certain cycle。Continuous feeding and discharging are carried out continuously。At present, periodic expression is commonly used。
3, according to its different form of process layout, can be divided into single-stage and double-stage two categories。
The sand, stone, cement and other materials are lifted to the roof bin in a single step, and all kinds of materials are weighed, batched and stirred according to the process flow until they are madeConcrete mixingThe materials are loaded and transported by car。Mixing floor is divided into bin layer, weighing layer, mixing layer and bottom layer from top to bottom。The single-stage process is reasonable, the productivity is high, but the factory is required to be high, so the investment is large, and the general mixing floor is mostly used in this form。
The two-stage material storage silos and mixing equipment are generally on the same level。The aggregate is lifted to the silo, where it is weighed cumulatively and separately before being delivered by lifting bucket or belt conveyoragitatorInternal stirring。Because the material needs to be lifted twice, the productivity is low, but the height of the full set of equipment can be reduced, the disassembly is convenient, and the investment can be reduced, the general mixing station uses this form。
