How does the crusher process basalt sand making, and how does the sand produced conform to construction sand?
Due to the large gap of sand and gravel in recent years, related companies have turned to artificial sand to make up for the impact of the shortage of natural sand. Basalt is a kind of ore with huge reserves and rich resources. Can basalt be used as artificial sand? Does basalt sand making meet the needs of construction sand?
The chemical and mineral components of basalt are basically the same as the raw materials of machine-made sand. It is possible to use it as the raw material of machine-made sand, and its fineness modulus can be controlled by the technical process in production. Generally, it can be divided into coarse sand, Medium sand, fine sand, and finished aggregates meet the requirements of construction sand. Because of their good adhesion, strong compressive ability and long service life, they are often used in concrete mixing, railways and highways, infrastructure facilities and other fields.
The advantages of using basalt as raw material and processed by crushing and sand making. Basalt is easy to process: easy to mine, and the finished product has uniform particle size and strong plasticity after crushing and sand making. Appearance: The aggregate made of basalt has sharp edges and corners, and contains many needles and is rough. Fineness modulus: The fineness modulus of the aggregate produced by basalt is adjustable, which can be controlled by different machine-made sand production processes, and in mass production, one kind of fineness modulus of natural aggregates has multiple gradations. It is fixed and cannot be controlled by humans. This drawback is solved for machine-made sand. The mud content, firmness, apparent density, loose bulk density, porosity, single-stage maximum crushing value, etc. of basalt manufactured sand must meet the relative requirements, so it can be used in construction projects instead of natural sand.
As for the process of processing Basalt in the machine-made sand production line, the jaw crusher can roughly crush the basalt with larger particle size. The size of the treated crushed stone meets the feeding requirements of the secondary crushing equipment. The initially broken crushed stone is sent by the conveyor to the impact crusher or cone crusher for medium and fine crushing. The stone with better particle shape is produced and screened by the vibrating screen. If the particle size of the crushed stone meets the discharging requirements, Send the conveyed feeder to the finished product pile; Those that do not meet the requirements of discharge particle size will be screened out and then sent to the sand making machine for treatment to make sand with finer particle size.
