GNZ centre drive efficient thickener is a kind of new-style solid-liquid separation equipment, and is designed by our company with the introduction of foreign advanced technology. The thickener has multiple national patents such as center drive, high-efficiency feeding hopper and automatic rake lifting technology. The adoption of the heavy-duty core design ensures the machine normal running in extreme conditions, greatly boosting the concentrating efficiency. GNZ type of high-efficient thickener achieves the efficient dewatering by the action of material itself gravity and flocculating settlement. The slurry is mixed with the flocculating agent in the feed tank and fed to the high-efficiency feed hopper (steady flow tank). After the degassing and energy dissipation by the steady flow tank, the material is fed along the horizontal tangent of the inner tank of the steady flow tank, which is equipped with multiple flocculent adding points based on the material nature; the material and the flocculating agent are settled downwards after mixed for the second times; then they are transported along the parabola direction by the distributor disc at the bottom of the tank; the settled material is scraped by the rake to the center throat of the pool body for centralized discharge.
PRODUCT ADVANTAGES
-High concentrating and scraping efficiency is three to five times than that of ordinary thickeners
- Excellent Feeding System - efficient steady flow tank
- Ultra-heavy-duty drive lifting system and large torque designs to ensure the normal operation of
equipment in extreme conditions.
- Logarithmic spiral design and teeth density upon the nature of the material for rake teeth is greatly improves the efficiency of scraping

Product Application
GNZ thickener is a new High-rate thickener with central-drive, automatic lifting rake that we have developed based on foreign technology .It is widely applicable to treatment of various industrial feed pulp, like coals, metal ore dressing water,
metallurgy, chemical, tailings treatment, environmental protection etc.
This thickener consists of round thickener and harrow scrapping machine, the solid particles suspend in thickener settling by gravity, the pulp in the upper turn into clean water, so that the separation can be realized. Slime that sediment in the bottom of the thickener is discharged by the harrow scrapping continuously, and clean overflow from the upside.
