Many new operators make the fatal mistake of purchasing Horizontal ??? ?? ?????? (HSI) for secondary crushing because of their lower initial purchase price and good shaping capabilities. However, when an HSI hits high-silica river gravel, the blow bars can wear out in a matter of days—sometimes hours. ?? initial capital savings are instantly wiped out by massive Operational Expenditure (OPEX).

Stage 3: Tertiary Crushing & Shaping – VSI Crusher

????? ?? ??? ??? ???? ????? ??????? ???? ???? ?? ??? ????? ??? ???? ???? ???? ??? ????? ???? ?? ???? ?? ????? ??? ?????? ??? ??? ?? ?? ?????? ??? ????-?????? ?????? ?? ??? ??? ASTM C33 ??????? ?? ????? ??? ?? ?? ?? ??? ???? ?? ????? ???

• ??: ??? ????? ???? ??????? (VSI) "???? ?? ????" (??? ???) ??? ??? ????? ??? ????
• Purpose: Produce final aggregates (5–31.5 mm) and manufactured sand (0–5 mm); improve cubicity.
• ?? ???? ??? ???? ??: Instead of flinging the abrasive stones against steel anvils, the "Rock-on-Rock" VSI builds a protective shelf of material inside the chamber. ?? incoming pebbles hit other pebbles. This allows you to achieve a perfect cubical shape and produce high-quality Manufactured Sand (M-Sand) without destroying the machine's internal steel components.
