First, the basic components of concrete mixing station. Mainly by the mixing of concrete mixing plant host material weighing system, material handling systems, material storage and control systems of five major component systems and other ancillary facilities. 1 mixer mixing mixing host its way into compulsory mixing and self-loading mixing. Forced mixer is mixing at home and abroad to use the mainstream, it can mix liquid, semi-rigid and rigid variety of dry concrete. Since the main host off the mixing of concrete mixing liquid, now rarely used in the mixing station. Forced mixer structure is divided into the spindle by planetary mixer, single horizontal shaft mixer and twin-shaft mixer. And especially in the twin-shaft compulsory mixer the best overall performance. The company's series of mixing used in all twin-shaft compulsory mixer. 2 material weighing system material weighing system is the quality of concrete and concrete impact on the cost of production of key components, divided into aggregate weighing, weighing powder and liquid weighing three parts. Under normal circumstances, less than 20 cubic meters per hour, mixing station overlay weighing methods, namely, aggregate (sand, stone) with a scale, a scale with cement and fly ash, water and liquid additive were weighed , and then put into water, said liquid additive pre-mix hopper. In more than 50 cubic meters per hour, mixing stations, the use of said material independent way of weighing, are all weighing scales and electronic computer control. Aggregate weighing accuracy ≤ 2%, cement, powder, water and admixtures weighing accuracy reached ≤ 1%. 3. Material handling material handling system consists of three parts. Aggregate transportation; currently mixing hopper conveyor and conveyor belt delivery with in two ways. Hopper to enhance the advantage of small size, simple structure. Belt conveyor has the advantage of conveying distance, high efficiency, low failure rate. Conveyor belt aggregate principal applies to the temporary storage of the mixing station, mixing station to improve productivity. Powder delivery; concrete powder is mainly used for cement, fly ash and slag. Now widely used in powder transport means is screw conveyor transport, large-scale mixing and scraper conveyor with pneumatic transport. Screw conveyor has the advantage of simple structure, low cost, and reliable. Mainly refers to the liquid transfer and liquid water additives, which are delivered by the pump.
