Generally speaking, the sand production line is mainly divided into five processes: feeding, crushing (coarse and fine crushing) , making sand, screening and transportation.
1, feeding selection of vibration feeder, also known as feeder, generally used for the front end of primary crushing equipment. During the production process, the bulk and granular materials can be fed into the crushing equipment from the hopper evenly, regularly and continuously.
2. Crushing is divided into coarse crushing and fine crushing, coarse crushing is generally selected jaw crusher, jaw crusher stable performance, large crushing ratio, reliable quality.
The fine crushing selects the cone crusher or the counterattack crusher. They are mainly used for secondary crushing in the production line of making sand. Cone crusher is mainly used for crushing high hardness stone, solid structure, long service life. Impact Crusher is mainly used for fine crushed soft stone, product particle size uniformity.
3, making sand is an important step in the production line, the general selection of VSI sand machine or impact sand machine to carry out the fine grinding of materials and modeling.
4. Vibrating screen for material screening: because the sand from the crusher is a mixture, it is necessary to use the vibrating screen to screen the stones of different sizes to form a reasonable gradation of macadam products.
5. The belt conveyor is also called belt conveyor or belt conveyor. The utility model has the advantages of strong conveying capacity, long conveying distance, simple structure, convenient maintenance, etc. . It is an indispensable material conveying equipment for sand making production line.
