1. PYNPUNT GEDREWE OPENING

Stygende bedryfskoste en onvoorspelbare stilstand erodeer jou sand- en gruismarges? Managing a modern aggregate operation presents distinct challenges that standard equipment often fails to address. Oorweeg hierdie algemene, duur scenario's:
Hoë Dra & Onderhoudskoste: Abrasive silica and gravel rapidly degrade standard components, lei tot gereelde, unscheduled shutdowns for liner changes, pump rebuilds, and conveyor belt replacements.
Inkonsekwente finale produkkwaliteit: Fluctuations in feed material cause offspec product—fines content too high or particle distribution out of grade—resulting in rejected loads and lost revenue.
Inefficient Water & Sludge Management: Ineffective washing and clarification systems waste process water, create environmental compliance hurdles, and lose valuable fines to settling ponds.
Low Overall Plant Efficiency: Bottlenecks at crushing, vertoning, or material handling stages limit total throughput, preventing you from capitalizing on highdemand periods.

What if your key processing equipment was engineered from the ground up to confront these specific abrasion, klassifikasie, and reliability challenges? The solution lies in partnering with a specialized contract manufacturer for your core sand gravel mining equipment.

2. PRODUK OORSIG

This content details a comprehensive line of stationary and modular sand washing, klassifikasie, and dewatering equipment manufactured under contract for sand and gravel mining operations. As your contract manufacturer, we engineer and build the core machinery that transforms raw feed into specification aggregate.

Operasionele werkvloei:
1. Voer & Verspreiding: Crushed material is evenly distributed into the washing system.
2. Uitputting & Bevryding: Rotating paddles or screws scrub particles to break down clay clots and liberate fines from coarse aggregate.
3. Hidrouliese klassifikasie: Precise water flow rates separate particles by size and specific gravity in settling tanks or hydrocyclones.
4. Mechanical Dewatering: Screws or vibratory decks remove excess water from fine and coarse products to meet shipping moisture specifications.
5. Boetes Verhaling & Waterbestuur: Integrated cyclones and thickeners capture ultrafine particles for byproduct sale while clarifying water for recirculation.

Toepassingsomvang: Ideaal vir die verwerking van maagdelike aggregaat, crushed stone rewashing, and construction/demolition material recycling. Primary limitations include maximum feed size (typically ≤1”) and the requirement for a consistent water supply; dry processing solutions are configured separately.
