[0002] In the process of mining metal minerals, a large amount of low-grade rough stone, i.e. solid waste stone, is often produced. These rough stones are huge in quantity, accumulate for a long time, occupy a lot of space, and landfill transfer will increase the cost of the enterprise. Using rough stone to process sand and gravel for building materials is an important way to utilize rough stone. There are mainly two methods: wet sand making and dry sand making. Among them, wet sand making technology is more mature and widely used. For example, a quartz sand production line with a utility model patent with a publication number of CN212383850U. However, wet sand making requires a lot of water resources and is restricted in some areas with scarce water resources. In the process of using dry sand making, mining companies now often only adopt an extensive sand making route, which is simple crushing and then screening. Crushing and screening are done separately, and there is no formed production line, so the production efficiency is low.

The discharge port of the powder selector 6 is connected to the humidifier 9 through the second conveyor belt 7. The humidifier 9 outputs the sand material for construction.
[0026] By reasonably setting the height difference between the silo 2 and the vibrating screen 5, it is convenient to connect the material transportation through the first conveyor belt 3; the crusher 1 is directly arranged across the silo 2, so that the crushed material directly enters the silo 2 for temporary storage. The setting of the powder selector 6 can remove dust from the powder under the screen, reduce the soil content in the sand, and improve the quality of building materials. Through the setting of the humidifier 9, the sand can be stirred and humidified to avoid the blowing of sand during the later transportation. The utility model of the mine rough stone dry sand making line can continuously crush and screen the dry rough stone, output building materials, and make sand efficiently.
[0027] In a specific embodiment of the present invention, Figure 1 and Figure 2As shown, the utility model mine rough stone dry sand making line also includes a dust collector 10 and an induced draft fan 11.

The powder selector 6 specifically adopts an unpowered air powder selector, and the specific model is AC20.5 of Jinlu (Tangshan) Intelligent Equipment Co., Ltd. Correspondingly, the vibrating screen 5 is a closed vibrating screen to avoid dust flying during the working process.
[0028] By providing the dust collector 10 and the induced draft fan 11, the under-screen material can be dusted, the impact of dust can be reduced, the product quality can be improved and the working environment can be protected.
[0029] In a specific embodiment of the present invention, Figures 1 to 3 As shown, there are two powder classifiers 6 , and the two powder classifiers 6 are connected in series to the material discharge port under the screen of the vibrating screen 5 .

The vibrating screen support 4 is divided into two floors and is surrounded by fences. Stairs are provided between the floor and the ground and between the floors to facilitate workers to go up and down. The rear of the vibrating screen support 4 is connected to the dust collector 10 support through a ladder.
[0033] By setting two sets of vibrating screens 5 in parallel to screen the crushed materials conveyed by the first conveyor belt 3, the working capacity of the crusher 1 can be matched and the screening efficiency can be improved; by connecting two powder selectors 6 in series at the material outlet under the screen of the vibrating screen 5, the dust in the sand material can be effectively removed and the cleanliness of the sand material can be improved.

The vibrating screen 5 with two layers of sieve plates screens the crushed mine rough stone material into materials with a diameter of more than 12 mm, materials with a diameter of 5 to 12 mm, and materials with a diameter of less than 5 mm. The materials with a diameter of more than 12 mm are transported to one side through a third conveyor belt 8 and transferred to the crusher 1 again for secondary crushing and shaping; the materials with a diameter of 5 to 12 mm are transported to the other side through another third conveyor belt 8 and stored separately, which can be used as building stone materials. The undersize material with a diameter of less than 5 mm is subjected to two dust removals through two powder selectors 6 connected in series to remove dirt and debris, and is transported to a humidifier 9 through a second conveyor belt 7. The humidifier 9 sprays, stirs and humidifies the dry sand material before outputting it.
[0038] The mine rough stone dry sand making line described in this case, by reasonably setting the height difference between the silo 2 and the vibrating screen 5, is convenient for material transportation connection through the first conveyor belt 3; the crusher 1 is directly arranged across the silo 2, so that the crushed material directly enters the silo 2 for temporary storage. The setting of the powder selector 6 can remove dust from the powder under the screen, reduce the soil content in the sand material, and improve the quality of building materials. Through the setting of the humidifier 9, the sand material can be stirred and humidified to avoid the blowing of sand during the later transportation. The utility model mine rough stone dry sand making line can continuously crush and screen dry rough stone materials, output building materials, and make sand efficiently. In addition, through the setting of the dust collector 10 and the induced draft fan 11, the material under the screen can be dusted, the impact of dust can be reduced, and the product quality can be improved while protecting the working environment. By setting two sets of vibrating screens 5 in parallel to screen the crushed materials conveyed by the first conveyor belt 3, the working capacity of the crusher 1 can be matched and the screening efficiency can be improved; by connecting two powder selectors 6 in series on the material outlet under the screen of the vibrating screen 5, the dust in the sand can be effectively removed and the cleanliness of the sand can be improved. By setting the vibrating screen 5 to have two layers of sieve plates, building stone materials can be screened out at the same time, thereby improving the economic benefits. By setting the vibrating screen bracket 4 to a station-type bracket, it is convenient for operators and maintenance personnel to monitor and repair the working conditions of the vibrating screen 5 and the powder selector 6. The crusher 1 uses a double-roll crusher, which has the advantages of low material moisture requirements, reliable performance, low power consumption and low dust. By equipping the batching machine 201 at the bottom of the silo 2, it is convenient to provide the crushed materials to the bottom of the first conveyor belt 3 in a quantitative manner, which can ensure that there is no material piling or shortage at the feeding end of the vibrating screen 5, and ensure the screening efficiency and quality.
