Producing high‑purity glass grade sand requires a quartzite crushing line 120 tph for glass grade sand that delivers consistent particle size and minimizes iron contamination. Quartzite is extremely hard (7‑8 Mohs) and highly abrasive, demanding a well‑engineered crushing circuit with careful attention to wear part selection. Below we describe a typical layout and how OCP Mechanical Company supports glass sand producers.
1. Why 120 tph Is a Practical Capacity for Glass Sand
A quartzite crushing line 120 tph for glass grade sand matches the demand of medium‑scale glass manufacturing plants or mineral processing operations. Glass grade sand typically requires 90% passing 0.6‑1.2 mm with strict limits on iron oxide (below 0.02‑0.05%). Quartzite’s high silica content (often >95% SiO₂) makes it ideal after proper crushing and washing.
OCP offers the Type Q crushing line, which includes a jaw crusher, cone crusher, vertical shaft impactor (VSI), vibrating screen, and sand washer. Note: Product data are constantly updated; for the latest specifications of Type Q, please contact our online customer service.
Typical equipment for a quartzite crushing line 120 tph for glass grade sand (for illustration only; actual data subject to continuous improvement):
Primary: Type J jaw crusher (feed opening 750x1,060 mm, CSS 100‑120 mm)
Secondary: Type C cone crusher (short head, CSS 8‑12 mm)
Tertiary: Type V VSI (rock‑on‑rock, low iron contamination)
Vibrating screen: 2 decks (1,500 x 5,000 mm) with polyurethane media
Sand washer: Type W (log washer or attrition scrubber) to remove fines
The above values are for illustration only. OCP continuously improves its products. Contact our online team for the most current data sheet.
Many glass sand producers in Southeast Asia, the Middle East, and South America have adopted this configuration, reporting stable gradation and acceptable wear costs.
2. Controlling Wear and Iron Contamination
Operating a quartzite crushing line 120 tph for glass grade sand requires balancing wear part life with strict iron avoidance. Quartzite is highly abrasive, and standard manganese or steel wear parts can introduce iron into the product. Therefore, we recommend:
Using ceramic or tungsten carbide tips in the VSI to minimize iron contamination.
Applying rubber or polyurethane liners in chutes and hoppers where possible.
Avoiding impact crushers with steel blow bars – they add iron and wear too quickly.
Installing a magnetic separator after the VSI to remove any tramp iron.
OCP’s Type V VSI can be equipped with a rock‑on‑rock chamber and carbide tips. Typical tip life for quartzite: 60‑100 hours, processing approximately 7,000‑12,000 tons per set. Actual wear life varies with feed size and operating parameters – please ask our engineers for a site‑specific estimate.
To keep your quartzite crushing line 120 tph for glass grade sand economical, we recommend:
Pre‑screening fines (below 3 mm) before the VSI to reduce tip wear.
Operating the VSI at moderate rotor speed (1,300‑1,500 rpm).
Using a closed circuit with a screen to return oversize to the VSI.
As a direct‑selling manufacturer, OCP provides factory pricing on carbide tips and wear parts, and we can ship to major ports worldwide within 15‑25 days.
