The dry sand production line, also known as a dry sand making production line, is a kind of production line that processes raw materials and stones into standardized construction sand without using water or a small amount of water. This kind of production line has the advantages of high automation, low operation cost, high crushing rate, energy saving, large output, less pollution, and so on.
- System Equipment: It consists of crusher, belt conveyor, bucket elevator, silo, square swing screen, and so on.
- Application: It is used to screen dry sand such as fracturing sand, quartz sand, silica sand, mechanism sand, ceramic sand, glass sand, resin sand, etc.
System equipment composition
Dry sand making production line mainly consists of crusher, belt conveyor, bucket elevator, vibrating screen, silo and so on.
- Coarse crushing equipment: such as jaw crusher, used for preliminary crushing of raw materials.
- Fine crushing equipment: such as cone crusher or impact crusher, which is used to further crush the roughly crushed stone to smaller size.
- Sand making equipment: such as impact crusher (sand making machine), used to process the finely crushed stone into sand.
- Screening equipment: such as vibrating screen, used to screen the materials after sand making, separating the sand particles that meet the requirements and the materials that need to be returned to reprocessing.
- Conveying equipment: such as belt conveyor, which is used to convey materials between various equipments.
- In addition, according to the demand of production process, it may also be equipped with dust removal equipment, coarse and fine powder separator and other auxiliary equipment.
Application materials
It is used for screening of dry sand such as fracturing sand, quartz sand, silica sand, mechanism sand, ceramic sand, glass sand, resin sand, and so on.
Silica Sand
Quartz Sand
Oil Fracturing Proppant- Ceramic Sand

Industry Salt
Cork powder- Calcium Carbonate
Production line flow
The process flow of dry sand making production line is roughly as follows:
- Raw material preparation: The raw stone is evenly fed into the jaw crusher for coarse crushing through vibrating feeder.
- Coarse crushing: the roughly crushed stone is fed into cone crusher or impact crusher for fine crushing through belt conveyor.
- Fine crushing: the finely crushed stone is again fed into the impact crusher (sand making machine) through belt conveyor for sand making.
- Screening: The material after sand making enters the vibrating screen for screening, separating the sand particles that meet the requirements and the material that needs to be returned for reprocessing.
- Finished Product Output: The sand particles that meet the requirements are output as finished sand through the belt conveyor, while the materials that need to be returned to be reprocessed are re-entered into the sand making machine for processing.
functions of each equipment in the production line
Crusher
