Applications of 2-tier screen

Main: Granulation and separation of mineral/industrial materials after crushing, before salt sand; Output: 3 sizes (high >50 mm, medium 10-50 mm, fine <10 mm).
Industries: Sand/gravel mining, iron ore, cement, recycling, petrochemical (separation from 350 microns to 350 mm).
Types: Linear vibrator (common), grizzly (for coarse materials), rotary (for powder).

Accurate separation with <2% loss, increased material quality (95% reduction in contamination) and 30% longer screen durability.
Low energy consumption (10 kW), adjustable vibration; suitable for modern sand making lines (after kubit).
Uniform texture, high safety (anti-vibration springs); flexible for floors 1-3.
Economical: Iranian production with OEM quality, easy installation (1 day).

Sensitive to high humidity (rusting mesh; anti-corrosion coating required).
Consumable part (replace mesh every 6-12 months in heavy duty).
Heavy weight (crane handling); sensitive to overload (reduced efficiency >100 t/h).
In used models, springs may become fatigued (check HB 180+).

Installation: On concrete base, 15-25° slope, connected to conveyor; leveling ±0.05 mm (1 day with crane).
Maintenance: Screen/spring inspection (every 200 hours), oil/grease lubrication; avoid sticky materials. Replace screen >5 mm wear.
Transport: Max. 10 tons for trailer (1 unit), 5 tons crane for installation.
