Classification of Concrete Plants
The construction of a concrete plant depends on the requirements for the finished product: quality, brand, planned consumption volumes, seasonality of use, availability of consumed resources, and other factors. By type of technological cycles are divided into factories:
- Ready concrete mixes (full cycle).
- Ready for direct use at construction sites and dry mixes (combined cycle).
- Dry mixes (split cycle).
One of the main indicators that determine how a concrete plant works are its productivity, which varies widely. For large enterprises, this figure is 300 m3 / hour, and for mini-factories - 5 m3 / hour. Industrial equipment is very popular in the construction business, providing the production of ready-mixed concrete in volumes of 50-60 m3 / hour. Productivity is usually calculated based on the average intensity of concrete laying during the warm season.
By location, plants are classified into:
Stationary; Focused on the continuous release of large volumes of products. The methods of their work involve full automation of production processes.
Mobile; They are located on small sites near the construction site. Their transportation can be carried out by one or two vehicles. Only a few hours are required for installation and dismantling.
Mobile; Their use is economically advantageous when performing work in areas of great length (long tunnels, channels, bridges, etc.). They can be built on temporary foundations. A concrete plant layout may also include separate mobile structures.
Concrete Plant Components
Depending on the number and type of concrete mixers, a plan for their location is carried out both in nesting and in a linear manner. In the first case, they are placed in one or two parallel lines. To ensure the operation of each mixer, the placement of dispensers and consumables is required.
The nesting method is economically more profitable since from 3 to 5 units of concrete mixing equipment can be concentrically located around the mixing plant. In this case, only one set of automatic dispensers is required. Equipment management when using a nesting scheme is simpler. The choice of layout depends on how the concrete plant will work, and the expected volume of capital investments.
