90 TPH Quartz Sand Screw Washer for Dewatering in Vietnam

Da Nang‘s Infrastructure Transformation: A Market Driving Unprecedented Aggregate Demand

Da Nang, Vietnam’s third-largest city and a key economic hub in the central region, is experiencing one of the most ambitious infrastructure expansions in the country‘s history. On August 25, 2026, Deputy Prime Minister Pham Gia Tuc officiated the groundbreaking ceremony for two key infrastructure projects with a total investment of over 4,293 billion VND (approximately US$165 million)**: the Le Thanh Nghi - Cach Mang Thang Tam - Thang Long - Hoa Xuan Bridge access road intersection cluster project and the Quang Nam Province Adaptive Integrated Development Project. These projects play a strategic role in completing the technical infrastructure system, strengthening disaster response capacity, and expanding the socio-economic development space of the locality. Meanwhile, Da Nang has approved an investment of more than **US$237 million to complete key infrastructure at Lien Chieu Port, transforming the facility into an international gateway port and logistics hub for central Vietnam. With the projected demand for construction materials during the 2026-2030 period reaching approximately 44.71 million m³, and the city‘s natural endowment of quartz sand in Hoa Khanh and glass sand in Nam O, operators processing quartz sand for construction and industrial applications are positioned for sustained growth. A 90 TPH quartz sand screw washer for dewatering in Vietnam delivers the capacity and efficiency needed to meet the capital‘s surging demand for specification-grade washed sand.

Why Screw Washers Are Essential for Quartz Sand Processing in Vietnam

Quartz sand from Vietnamese deposits—particularly from Da Nang‘s coastal and riverine sources—typically contains significant quantities of silts, clays, and fine impurities that must be removed before the material can be used in high-value construction, glass, and industrial applications. Fine material screw washers, often called sand screws, are among the simplest and most effective devices for washing sand and removing silts and clays. These machines efficiently separate unwanted materials from particles up to 10 mm—typically collected from washing screen underflow—while simultaneously dewatering and conveying the clean sand out of the pool. For quartz sand processing, where product purity directly affects commercial value, a screw washer integrates washing, classification, and dewatering functions into a single unit. The screw mechanism tumbles the sand with water to dislodge impurities, while the inclined trough allows fines and water to overflow at the weir end, leaving clean, dewatered sand to discharge from the upper end. For a 90 TPH quartz sand screw washer in Vietnam, the equipment must be sized to handle the specific feed characteristics of local quartz sand—typically with a maximum particle size of 10 mm and moisture content that varies seasonally. The dewatering capability is particularly critical in Vietnam‘s tropical climate, where high rainfall can increase feed moisture and complicate downstream handling.

Key Parameters for a 90 TPH Quartz Sand Screw Washer

Selecting the right screw washer for a 90 TPH quartz sand dewatering application requires careful evaluation of several critical parameters. The screw diameter and length determine the machine‘s capacity and retention time—for a 90 TPH application, a screw diameter of 760–920 mm is typically required, with trough lengths of 7–9 metres providing adequate retention for effective washing and dewatering. The motor power for a 90 TPH screw washer generally falls in the 11–22 kW range, depending on screw diameter and material characteristics. Outboard bearing designs with water-sealed housings are essential for preventing water ingress and extending bearing life in wet applications. PU wear liners on screw flights significantly extend service life when processing abrasive quartz sand. The weir height and pool depth determine the washing intensity and fines removal efficiency—adjustable weirs allow operators to fine-tune the wash water level to achieve the desired product cleanliness. For Vietnamese quartz sand operations, where feed material can vary significantly between dry-season and wet-season conditions, the ability to adjust these parameters is essential for maintaining consistent product quality.

The Vietnam Quartz Sand Market: A Growing Export Hub

Vietnam has emerged as a significant player in the global quartz sand market, leveraging its abundant resources, competitive energy costs, and strategic port infrastructure. With cheap hydropower and port advantages, Vietnam has become a low-end foundry sand export centre, with 2026 exports exceeding 5.4 million tonnes, accounting for 12.7% of global foundry sand trade. The country is also gaining traction as a processing hub and consumption centre for high-purity quartz sand. The Vietnam quartz sand market is supported by ongoing infrastructure development, with government projections indicating that sand supply currently meets only 21-27% of demand for major projects. This supply-demand gap underscores the importance of efficient processing equipment that can maximise recovery from available quartz sand resources. For operators in Da Nang and surrounding provinces, a 90 TPH quartz sand screw washer represents a strategic investment in capturing value from local quartz sand deposits—whether supplying construction-grade sand for infrastructure projects, foundry sand for industrial applications, or feed material for higher-purity processing.
