In the previous discussion, we focused on five essential pieces of equipment often employed in quartz sand beneficiation including rod mills, magnetic separators, flotation machines, hindered settlers, and XCIII hydrocyclones. This article will shift its focus to another set of five critical devices widely utilized in quartz sand concentration plants—specifically, high-frequency high-efficiency dewatering screens, inclined plate thickeners, scrubbers, desliming buckets, and slurry pumps.

01

High-Frequency High-Efficiency Dewatering Screen

Back

The high-frequency high-efficiency dewatering screen comprises several key components: a vibration motor, a sieve, a dewatering frame, and a support structure with rubber springs. This equipment stands out as a highly effective dewatering solution characterized by its straightforward design, easy maintenance, and user-friendly operation.

Within the quartz sand concentration framework, this dewatering screen employs an innovative sieve plate structure. The motor generates high-frequency vibrations, which limit the likelihood of pulp particles passing through the screen holes, thereby enhancing dewatering efficiency and leading to a final water content of under 15% in dry tailings.

02

Inclined Plate Thickener

Back

The inclined plate thickener serves as slurry gravity separation equipment designed with inclined parallel plates in the settling zone. This machinery features an upper container and a lower cone.

In quartz sand processing, the inclined plate thickener efficiently performs concentration tasks through its independent inclined plate channels. The fine-grains overflow and clean water are discharged directly from each channel, preventing short-circuiting and the recirculation of fine particles, which enhances classification and concentration efficiency. The system can achieve over 70% return water efficiency. Compared to traditional thickeners, the inclined plate thickener used in quartz sand concentrators expedites ore particle separation, shortens settling times, and boosts production capacity by nearly threefold.

03

Scrubber

Back

The scrubber utilizes mechanical and grinding forces to eliminate thin-film iron and unwanted impurities from the quartz sand surface. This process also separates unformed mineral aggregates for further purification operations. The current scrubbers available for quartz sand mainly consist of high-efficiency stirring scrubbers and spiral groove scrubbers.

The high-efficiency stirring scrubber includes a motor, a reducer, a main shaft, and specially designed rubber impellers. The motor rotates the impellers, producing a strong scrubbing action. This robust design is suited for natural or artificial sands with mineral sizes from 0-6 mm and is very effective in removing contaminants.

Conversely, the spiral groove scrubber—consisting of a groove body and helical blades—operates by rotating blades against each other, scrubbing off adhering mud and rinsing with high-pressure water for effective cleaning.

04

Desliming Bucket

Back

The desliming bucket is a straightforward solution used for classification, desliming, and concentration of substances. The pulp is introduced into the cylinder, allowing coarse particles to settle and be extracted, while finer particles move into the overflow tank. This equipment typically handles feeds smaller than 2 mm, effectively separating particles to 75 um or finer.

05

Slurry Pump

Back

A critical component in quartz sand concentrators, the slurry pump efficiently conveys slurry to the desliming bucket or box filter press. Its lining made of XH wear-resistant rubber not only fortifies its durability but also sustains optimal performance across other slurry transportation systems.

Conclusion

Back

Ultimately, the choice of quartz sand beneficiation processes and equipment is influenced by various factors, including the characteristics of the quartz sand ore, operational conditions, and budget constraints. To achieve a cost-effective and environmentally responsible selection of quartz sand, it is advisable to conduct a mineral processing test. This test permits a comprehensive analysis of the ore's properties and helps generate a scientific report, ensuring that the most suitable quartz sand beneficiation process and quartz sand beneficiation equipment is utilized. The final beneficiation plan should be reflective of the plant's unique situation and investment strategy to ensure favorable returns.
