The main chemical composition of the river pebble is silica, followed by a small amount of iron oxide and trace amounts of manganese, copper, aluminum, magnesium and other elements.It is an ideal building material with hard quality, natural stone properties resistant to pressure, abrasion and corrosion.
The river pebble production process uses gravel of 0-40mm as raw material.Using vertical shaft impact crusher (sand making machine) on the production line configuration,this crusher is a new sand making machine of Dewo. It is characterized by high crushing efficiency (with fine crushing and coarse grinding function), simple structure, convenient installation and maintenance, low running cost and excellent product granularity (in cube and needle-like content less).
There are river pebble resources, which vary from place to place. Therefore, when configuring the equipment, the wear resistance of the solution should be put in the first place. Large particle size can refer to the crushing of granite and basalt; small particle size needs to be pre-screened to reduce production cost;
Take the river pebbles below 200mm as an example:The material is pre-screened in the raw material warehouse through the feeder and belt conveyor to the 1# vibrating screen. The material larger than 40mm enters the cone crusher to crush, and the 5-40mm enters the vertical impact crusher for crushing,0-5mm enters the sand washing machine, and the finished product is directly discharged after cleaning.The crushed product of the cone crusher enters the 2# vibrating screen and is screened.The return cone crusher larger than 40mm breaks and breaks again, forming a closed loop,less than 40mm into the vertical impact crusher crush.The material from the vertical impact crusher enters the 3# vibrating screen,more than 20mm returning vertical impact crusher to break, forming a closed loop.Material less than 20mm is transported to the finished product pile via a belt conveyor,according to the cleanliness of the raw materials, it is considered to send the materials of 0-5mm to the sand washing machine for cleaning.
The sand production line has reasonable configuration, high degree of automation, low operating cost, high breaking rate, energy saving and environmental protection, large output and easy maintenance. The machined sand produced meets the national construction sand standard, the product has uniform particle size, good granular shape and reasonable gradation.
Remarks: The equipment configuration of the sand production line is mainly determined by the customers specifications for the sand and the output and the use of the sand.We provide solution and technical support, configure the process according to the customers production site, and strive to achieve a reasonable and economical production line for customers.
The diabase composition is equivalent to the diagenetic gabbro.Crystalline, fine-medium, dark gray-grey black,dark gray, grayish black.The diabase is a superior building material and is an excellent asphalt concrete gravel for roads.
Diabase crushing/sand making production line has the characteristics of reasonable configuration, high degree of automation, low operating cost, high breaking rate, energy saving and environmental protection, large output and easy maintenance.The sand and gravel aggregate produced meets the national construction sand standard, and the product has uniform particle size, good granular shape and reasonable gradation.
The bulk diabase material is uniformly fed by the vibrating feeder through the silo.It is conveyed to the jaw crusher for coarse crushing. After the coarsely crushed material is sieved by vibrating sieve, it is conveyed by the belt conveyor to the cone crusher to break and be finely crushed.
The diabase particles less than 40 mm after crushing are sent to an 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.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.
The diabase sand production line carefully developed by Dewo technicians has the characteristics of reasonable configuration, high degree of automation, low operating cost, high breaking rate, energy saving and environmental protection, large output and easy maintenance. The sand and gravel aggregate produced meets the national building sand standard. The product has uniform particle size, good grain shape and reasonable gradation.
Remarks:The production line is mainly based on the actual material size and the customers 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.
Dewo machinery can provides complete set of crushing and screening line, including Hydraulic Cone Crusher, Jaw Crusher, Impact Crusher, Vertical Shaft Impact Crusher (Sand Making Machine), fixed and movable rock crushing line, but also provides turnkey project for cement production line, ore beneficiation production line and drying production line.
