River gravel sand aggregate production line equipment

Construction of sand is sand, desert sand is fine, and the cement with strength is not enough. Concrete is composed of gravel and coarse sand (large volume) (volume) of cement (small size), this combination can get the highest density of unit. At present, the most commonly used aggregate production equipment is the jaw crusher, cone crusher and sand making machine. The HJ series high jaw Shanghai sebang research and development to create the crusher has been successfully listed, after debugging, quality inspection, test and other procedures, ready to be sent to Qinghai, to give the power of microblogging for Fujian infrastructure. Along with equipment and feeder, crusher, sand making machine, vibrating screen, sand washing machine, composed of a complete set of sand production line. It is the client configuration of the aggregate production line equipment mainly fractured basalt, basaltic bulk density is 2.8 ~ 3.3g/cm3, the density of compressive strength is very big, can be as high as 300MPa, sometimes higher, there are glass and porosity, the strength decreased. Durability of basalt is very high, joints, and joints as the Pentagon or hexagon, composed of columnar joints. Customers of the basalt crushed aggregate. Customers of the gravel crushed aggregate for concrete mixing station, near the main use, so the relatively high requirements for aggregate.

After several years of experience in production research, aggregate production line equipment in Shanghai state of the world to create, produce quality products sand texture hard, clean, well graded; the fineness modulus of uniform and stable, and is controlled in the range of 2.4-2.8; the finished sand stone powder content uniformity and stability, and is controlled in the range of 10%-15%; and to ensure the finished sand moisture stable and uniform rate, moisture content control in less than 6%, the maximum does not exceed 7%; gravel type uniform, a cube, flakiness content. There is a need to understand the basaltic sand and gravel production line process, you can consult, we will serve for you with all sincerity.
