Basalt, the main component of the oceanic crust, is a basic volcanic rock. Basalt has the advantages of strong pressure resistance, low crushing value, strong corrosion resistance and good asphalt adhesion. It is an internationally recognized material for building stones for railways, railways and airport runways.Not only that, but basalt is also a high-quality aggregate of lightweight concrete for high-rise buildings. Because of its many pores and hard characteristics, blending it into concrete can reduce the weight of concrete, but it is also strong and soundproof. The advantages of heat insulation are favored by major building materials markets.
The processing of basalt is divided into three stages: coarse crushing, medium fine crushing and sand making. According to the actual material size of basalt and the customer’s requirements for product granularity, Dewo engineers can provide customers with basalt production line solutions and technical support, and we can also design non-standard parts according to the actual installation conditions of customers.
The first stage: coarse crush
The basalt bulk material is uniformly fed by the vibrating feeder through the silo, and conveyed to the jaw crusher for coarse crushing. After the coarsely crushed material is sieved by the vibrating screen, it is transported by the belt conveyor to the cone crusher to break and be finely crushed.
Second stage: fine crushing
After the basalt conveyed to the cone crusher is finely crushed, it is sieved by a circular vibrating sieve, and the material of 40 mm or more is returned to the cone crusher to be broken again.
The third stage: sand making
The basalt particles less than 40 mm after crushing are sent to impact crusher (sand making machine) for further crushing and shaping, and the material of 20 mm or more is returned to the sand making machine for fine crushing again. The material less than 20mm is sent to the circular vibrating screen for screening and packaging. If the basalt needs to be cleaned, it can be sent to the sand washing machine for cleaning.
Basalt processing technology:
The basalt production line launched by Dewo has high automation, high breaking rate, low operating cost, energy saving and environmental protection, uniform product size, good grain shape and reasonable grading.
Remarks:The production line is mainly based on the actual material size and the customer’s requirements for product granularity. According to different production site conditions, Dewo engineers can provide customers with process planning and technical support, and we can also design non-standard according to the actual installation conditions of customers and supporting components, etc., we strive to achieve a reasonable and economical production line for customers.
