1. PYNPUNT GEDREWE OPENING

Managing a sand and gravel operation presents distinct challenges that directly impact your bottom line. Ervaar jy:
High Downtime from Wear: Abrasive silica and aggregate rapidly degrade standard components, lei tot gereelde, unplanned maintenance stops that cost an average of $850 per uur in verlore produksie.
Inkonsekwente produkgradering: Fluctuations in feed material cause offspec product, resulting in pile contamination, rejected loads, and diminished profitability per ton.
Excessive Fines Generation: Inefficient crushing and screening creates an overabundance of nonmarketable fines, wasting valuable tonnage and compliculating water management in wash plants.
Stygende energiekoste: Ouer, nonoptimized equipment consumes disproportionate power per ton processed, making energy a topthree operational expense.
Laat toe & Space Constraints: Static, sprawling plant layouts limit site options and increase permitting hurdles for new deposits.

Die sentrale vraag vir aanlegbestuurders is: how can you increase throughput of inspec material while systematically reducing cost per ton? The solution lies in selecting equipment engineered specifically for the rigors of sand gravel mining.

2. PRODUK OORSIG: HighCapacity Sand & Gruisverwerkingsaanleg

This integrated processing system is engineered for highvolume sand and gravel extraction. It transforms raw feed from a pit or dredge into precisely graded concrete sand, messelwerk sand, and various aggregate fractions (bv., ¾”, ½”, pea gravel).

Operasionele werkvloei:
1. Primêre groottevermindering: Raw feed is introduced to a robust primary crusher (bv., kaak of draai) to reduce large cobbles and boulders.
2. Scrubbing & Wasgoed: Material is fed into a log washer or scrubber to break down clay clods, remove contaminants, and prepare the matrix for classification.
3. Wet Screening & Klassifikasie: Screens separate material by size. Sand fractions are routed to cyclones or a fine material washer for dewatering and precise classification to meet ASTM C33 or other specifications.
4. Sekondêre/tersiêre verplettering: Oversize stone from screens is sent to cone crushers for further reduction to desired aggregate sizes.
5. Voorraad opgaar & Loadout: Clean, graded products are conveyed to radial stackers for inventory management and efficient truck loading.

Toepassingsomvang & Beperkings:
Omvang: Ideaal vir alluviale afsettings, gletser tot, and riverrun gravel pits producing commercial construction aggregates. Effective for deposits with moderate to high clay content when configured with washing equipment.
Beperkings: Not suitable for hard rock (graniet, val rots) mining without significant reconfiguration. Site requires adequate water supply and slurry containment/management systems.
