Below are classical design for manufactured sand production:
1.Vibrating feeder + jaw crusher + cone crusher + Deep Rotor VSI Crusher + vibrating screen
High crushing ratio of cone crusher and small crushed size ensures feeding size and crushing efficiency of VSI impact crusher. Deep Rotor VSI Crusher is the third generation of manufactured sand equipment and has many important improvements on vital working parts,like spindly impact plates which has a much longer life time. Advanced hydraulic set used makes maintenance easier and it is suitable for large scale manufactured sand production line of high automation degree.
This manufactured sand production line has a long life time for spare parts,long consecutive working time and easy maintenance. All this increases the overall economic benefits greatly.
2.Vibrating feeder + primary jaw crusher + secondary jaw crusher + Deep Rotor VSI Crusher + vibrating screen
In this design secondary jaw crusher is used to replace cone crusher. It can decrease once and for all cost of investment and is suitable for medium and small size manufactured sand production line.
The complete sand production line has a long life time for spare parts,long consecutive working time and easy maintenance. It has a low once and for all investment cost and good overall economic benefits
3.Vibrating feeder + jaw crusher + cone crusher + VSI Crusher + vibrating screen
In this design VSI crusher is used to replace Deep Rotor VSI Crusher which is used in the first design. VSI crusher has a lower investment cost compared with Deep Rotor VSI Crusher , it also has hydraulic setting and is easy to maintain and change spare parts.
4.Vibrating feeder + primary jaw crusher + secondary jaw crusher + P series VSI crusher + vibrating screen
This is the most economic design. The disadvantage is that P series VSI crusher has no hydraulic system,its maintenance and usage is also relatively complicated. Outstanding advantage of this design is that it has a much lower investment cost.
1. Because of DR series vertical shaft impact crusher self crushing principle, the shape of manufactured sand is cubic shape.
2. The rank of manufactured sand is reasonable, fineness modulus is adjustable.
3. Index of manufactured sand is accord with the standard of country, and is the high quality concrete aggregate.
