1. mixing console
Mixer stirring their way into forced mixing and self-loading mixing. Compulsory mixer mixing station is the main domestic and international use, it can be stirred liquidity, semi-rigid and rigid and other dry concrete. Since the fall mixing console main fixed concrete mixer for sale stirring fluidity concrete, it is rarely used in the mixing station. Compulsory mixer according to the spindle structure is divided into a planetary mixer, single horizontal shaft mixer and twin-shaft mixer. The integrated use of performance especially in the twin-shaft compulsory mixer is best. The companys series mixing station in all twin-shaft compulsory mixer.
2. Material weighing system
Material weighing system is affecting the quality of concrete and concrete production cost of key components, mainly divided into aggregate weighing, weighing powder and liquid weighing three parts. Under normal circumstances, 20 cubic meters per hour or less mixing station superposition weighing methods, namely aggregates (sand, stone) with a scale, a scale with cement and fly ash, water and liquid additive were weighed and then put into the water, said liquid additive pre-mixed infighting. In more than 50 cubic meters per hour, mixing station, said the use of various materials weighing independent manner, all have adopted electronic weighing scales and computer control. Aggregate weighing accuracy ≤2%, cement, powder, water and additives weighing accuracy have reached ≤1%.
3. The material conveying system
Material Handling consists of three parts. Aggregate transportation; mixing station currently has a hopper conveyor and conveyor belt conveyor in two ways. Advantages bucket elevator is a small footprint, simple structure. Advantages belt conveyor is conveying distance, high efficiency, low failure rate. Conveyor belt is mainly used to aggregate temporary storage of mixing station, thus increasing productivity mixing station. Powder conveying; concrete available powder mainly cement, fly ash and slag. Currently powder conveying way screw conveyor transport is widely used, there is the use of large mixing floor scraper pneumatic conveying and transport. Advantages of the screw conveyor is simple in structure, low cost, and reliable. Liquid delivery mainly refers to water and liquid additives, 20z-meter truck mounted concrete boom pump price which are respectively delivered by the pump.
4. Material storage systems
Substantially the same concrete materials available for storage. Aggregate open dumps (and there are large-scale urban commercial concrete mixing station with a closed silo); powders with fully enclosed steel silo storage; admixture with a steel container.
5. Control System
Mixing station control system is the central nervous system of the entire device. Control system according to the different requirements of users and the size of the mixing station and have different functions and preparation, construction of small mixing station control system simpler site available under normal circumstances, but the system is relatively large mixing station complex.
