Description

Mixing station aggregate screening vibrating screen Technical Field The utility model belongs to the technical field of stirring stations, and particularly relates to a stirring station aggregate screening vibrating screen. Background At the moment of the vigorous development of the building industry, concrete is used as a basic building material, and the quality of the concrete directly influences the safety and durability of a building. The aggregate is used as a key component of the concrete, and accounts for about 60% -80% of the total volume of the concrete, and the quality plays a decisive role in the performance of the concrete. The high-quality aggregate is required to have uniform particle size and reasonable grading, so that accurate aggregate screening becomes a core link in the production flow of the stirring station. Early stirring stations are usually manually or simply mechanically screened in the aggregate screening process. Manual screening relies on a large amount of manpower, and is inefficient and screening precision is greatly influenced by human factors, and is difficult to meet the large-scale and high-quality concrete production requirements. For example, in large building projects, the daily demand for concrete can be thousands of cubic meters, and standard aggregate cannot be timely supplied by manual screening. Simple mechanical screening devices, such as simple trommels, have several limitations, although they increase the screening efficiency to some extent. The screening precision is limited, and the aggregate is difficult to accurately grade, so that the concrete grading is unreasonable, and the performances such as strength and workability are affected. Meanwhile, when wet or sticky aggregates are treated by the rotary screen, the phenomenon of blocking of the screen holes is very easy to occur, the screening efficiency is further reduced, and the equipment maintenance cost is increased.
