Brief Introduction of River Pebble Sand Making Scheme:
There are many river pebble resources in China. Its main chemical composition is silicon dioxide, followed by a small amount of iron oxide and trace elements such as manganese, copper, aluminium, magnesium and other compounds. Its quality is hard, and it has the characteristics of compression resistance, wear resistance and corrosion resistance. It is an ideal building material. At present, River pebble sand production lines are being constructed all over the country, which effectively guarantees the supply of high-quality sand aggregate for national infrastructure projects.
The production process of river pebble is to use 0-40mm gravel as raw material and vertical impact crusher (sand making machine) in the production line configuration. This crusher is a new type of Shanghai Hengyuan sand making machine with high crushing efficiency (fine crushing and rough grinding function), simple structure, easy installation and maintenance, low operation cost, excellent product granularity (cubic, needle-like content is very small). Characteristics.
The basic process of river pebble production line:
There are many river pebble resources in China, which vary from place to place. Therefore, in the configuration of equipment, wear resistance of the scheme should be put in the first place. The crushing of large size reference granite and basalt, and the pre-screening of small size are needed to reduce production costs.
Take river pebbles below 200 mm as an example: the material is pre-screened in the raw material silo by feeder and belt conveyor to 1# vibrating screen, the material larger than 40 mm is broken into cone, 5-40 mm is broken into vertical impact, and 0-5 mm is washed into sand washing machine, then the finished product is directly discharged. 2 3 # vibrating screen is used to screen the material which is broken by vertical impact, and the material which is larger than 20 mm is broken by return vertical impact, forming a closed circuit cycle. The material less than 20 mm is conveyed to the finished material stack by belt conveyor. According to the cleanliness of the material, the material of 0-5 mm can be sent to the sand washer for cleaning.
Performance introduction of river pebble sand production line:
The sand production line has reasonable configuration, high automation, low operation cost, high crushing rate, energy saving, environmental protection, large output, easy maintenance, and the manufactured sand meets the national building sand standard. The product has uniform particle size, good grain shape and grade coordination.
The equipment configuration of the sand production line is mainly based on the specifications of sand and the output of sand and the use of sand. We provide scheme cooperation and technical support. We configure the process according to the production site of customers and strive to achieve the most reasonable and economical production line for customers.
