Gesertifiseerde Sandgruismynvervaardiger: HighCapacity Processing Solutions for Commercial Operations

1. PYNPUNT GEDREWE OPENING

Your sand and gravel mining operation faces three persistent challenges: declining feed quality from variable deposit conditions, escalating maintenance costs from abrasive wear, and tightening environmental compliance standards. Industry data indicates that unplanned downtime in aggregate processing can cost $5,000–$15,000 per hour in lost production, while substandard material classification leads to 8–12% yield loss in finished products. Are your current screening and washing systems delivering consistent 95%+ efficiency across multiple size fractions? Can your existing fabricator handle feed rates exceeding 500 TPH without compromising product specification? If your answer is no, you are losing margin on every ton processed.

2. PRODUK OORSIG

Die Gesertifiseerde Sandgruismynvervaardiger is 'n modulêre, heavyduty processing plant designed for continuous wet or dry classification of sand and gravel from 0.075 mm aan 150 mm. It integrates primary screening, hydraulic classification, and dewatering into a single structural frame.

Operasionele werkvloei:
1. Voerinname: Runofmine material enters via vibrating grizzly feeder (fines removal < 20 mm).
2. Primêre sifting: Multideck inclined screen separates gravel (+4.75 mm) van sand (4.75 mm).
3. Hidrouliese klassifikasie: Sand fraction passes through hydrocyclone cluster for silt removal (< 75 mikron).
4. Ontwatering: Classified sand discharges onto dewatering screen achieving 15–18% moisture content.
5. Voorraad opgaar: Conveyor system transfers finished products to radial stackers.

Toepassingsomvang: Suitable for alluvial deposits, riverbed mining, and crushed rock fines processing. Beperkings: Not designed for claybound materials exceeding 15% plasticity index without prewashing.
