Concrete building materials processing plant

Crushing and grinding equipment used in the manufacturing technology components for the production of Concrete building materials, especially in demand for concrete production line. There are several reasons. In the design of concrete are based on the need to obtain a given strength of the finished material and technology of concrete mix, and at the same time seek to minimize the consumption of cement and water.

The number of cement paste (cement + water) from the prescribed conditions for obtaining concrete conjoint structure in which the entire volume of voids in the rubble filled with cement-sand mortar with a small separation of the grains to ensure their lasting bond. Thus, the minimum flow of cement grout meets the minimum values ​​of “emptiness” and the total surface of the components of a mixture of fillers. The adopted technology the most dense packing (minimum “emptiness”) aggregates reached an optimal ratio of the fractions and the approach to the form of grains Cp = 1. The ideal form to fill – the ball. Close to the ideal – a cube for hence the requirements for the components of the cuboid.

The use of VSI crushers provides aggregates (gravel and sand) of size 20 mm low-prickly and laminar grains and form factor, which is close to the desired. At the same time, and large and small aggregates were equally effective can be classified into factions. It is the quality (cuboid) grains can do it. According to research specialist Civil Engineering (LISI), the use of VSI crushers can improve the characteristics of the original gravel and sand to get satisfying the requirements of GOST 8736-93. At the same time confirmed the essential advantages of the method of manufacturing the material using our equipment – VSI crushers:

• The content of the grain shape and needle plate is reduced by 4 times,
• strength of crushed gravel is one mark higher than the strength of the source material due to the destruction of weak links and reduce fracture of grains,
• The content of dust and clay particles of all samples corresponds to the regulatory requirements. It is important for manufacturers of building materials; the result of testing is to confirm in practice the possibility of obtaining desired properties of concrete with a decrease in cement consumption by 9-10%.
