The basic composition Commodity concrete mixing station consists of mixing system, aggregate supply system, powder storage systems, measurement systems, control systems and external ancillary equipment. Mixing System Mixing system according stirred divided into compulsory mixing and self-loading mixing. Compulsory mixer is mixing station at home and abroad mainstream use, it can be stirred liquidity, semi-rigid and rigid and other dry concrete. js750 twin shaft mixing machine concrete mixer for sale Since the fall mixing console main stirring fluidity concrete, 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. Aggregate supply system Aggregate supply system consists of aggregate storage silos, aggregate hopper and metering aggregate delivery of three parts. Aggregate conveying: conveying mixing station has a hopper and belt conveyor transport 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 transport: concrete available powder mainly cement, fly ash and slag. Powder conveying screw conveyor is used by general delivery, have adopted large mixing floor scraper pneumatic conveying and transport. 2013 new style twin-shaft concrete mixer with ce china Advantages of the screw conveyor is simple in structure, low cost, and reliable. Liquid conveying: mainly refers to water and liquid additives, which are respectively delivered by the pump. Metering System Metering 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%. Control System Mixing station control system is the famous twin shaft js1500 china concrete mixer factory 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. Grouped equipment Water, gas, silos
