Fixed concrete mixing plant is mainly used for the production of concrete, which is a kind of large-scale, centralized material supplying and automatic measuring concrete processing equipment. Concrete mixing plant mainly consists of 5 major systems such as mixing host, material weighing system, material conveying system, material storage system and control system and other ancillary facilities. The main purpose of stationary concrete mixing plant is to centralize the mixing of various raw materials, produce concrete that meets the requirements, and transport it to the construction site. With high production efficiency, the fixed concrete mixing plant is able to meet the demand for large quantities of concrete, and is widely used in construction fields such as bridges, roads and houses.

 
Common models of fixed concrete mixing plant include HZS25, HZS35, HZS50, HZS60, HZS75, HZS90, HZS120, HZS180, HZS240 and so on. Among them, HZS25, HZS35, HZS50, HZS60, HZS75, HZS90 belong to small and medium-sized concrete mixing plant, while HZS120, HZS180, HZS240 and so on belong to large-scale concrete mixing plant equipment. In addition, for some concrete production line, some users in order to increase the output, but also can be configured with dual-machine stationary concrete batching plant equipment, that is, the use of two sets of concrete mixer work at the same time, such dual-machine concrete mixing plant are: 2HZS25 concrete mixing plant, 2HZS35 concrete mixing plant, 2HZS50 concrete mixing plant, 2HZS60 concrete mixing plant, 2HZS75 concrete mixing plant, 2HZS90 concrete mixing plant, 2HZS120 concrete mixing plant and so on.
 
The service life of fixed concrete mixing plant depends on many factors, such as equipment quality, manufacturing process, use of the environment, maintenance and so on. Generally speaking, the service life of the stationary concrete mixing plant is between 5-10 years. If the quality of the equipment is poor or the use environment is bad, the service life may be shortened. In order to prolong the service life of fixed concrete mixing plant, regular maintenance is required, including inspection and lubrication of mixing blades, mixing arms, motors and other parts, as well as cleaning and maintenance of mixing cylinders, hoppers and so on. In addition, it is also necessary to pay attention to the environment in which the equipment is used, such as avoiding direct sunlight and keeping the equipment dry.
