Quartz milling line for Vietnam silica products

Introduction to Vietnam’s Silica Industry

Vietnam is one of the leading producers of high-quality silica sand in Southeast Asia, with vast deposits located in coastal provinces such as Quang Ninh, Da Nang, and Binh Thuan. These silica sands are essential raw materials for the glass, ceramics, foundry, construction, and electronics industries. With the rapid industrialization and the increasing demand for value-added products, there is a growing need for efficient, reliable, and cost-effective quartz milling solutions. The correct milling line not only ensures the required particle size distribution but also boosts productivity and reduces energy consumption. Shanghai Zenith Machinery Co., Ltd., an excellent manufacturer of ore grinding equipment in China, has developed a comprehensive range of mills that perfectly meet the requirements of Vietnam’s silica processing sector.

The Importance of Quartz Milling

Quartz (silica) is a hard, crystalline mineral that requires specialized grinding equipment to achieve the desired fineness. In applications such as flat glass production, the typical target is a particle size of around 200-325 mesh. For high-end ceramics and paint fillers, ultra-fine powders down to 5-10 microns are often required. Milling also liberates impurities and improves the brightness and chemical purity of the final product. Therefore, selecting the right milling line is critical to the profitability and competitiveness of any silica processing plant in Vietnam.

The Complete Quartz Milling Line

A typical quartz milling line comprises three main stages: primary crushing, grinding, and classification. Each stage must be carefully designed to handle the abrasive nature of silica while maintaining high uptime and low operating costs.

Crushing Stage

Run-of-mine quartz lumps are first reduced by a jaw crusher or impact crusher to a size suitable for the grinding mill, typically below 30-50 mm. A vibrating feeder ensures a uniform feed rate. For Vietnam’s silica operations, we often recommend a combination of a primary jaw crusher and a secondary hammer mill or cone crusher to achieve the optimal feed size.

Grinding Stage

This is the heart of the milling line. Depending on the target fineness and capacity, different mills are employed. For medium to fine grinding (100-400 mesh), the MTW Trapezium Grinding Mill is an outstanding choice. Its patented trapezoid work surface and multilayer sealing system provide high grinding efficiency, long service life, and low maintenance. For capacities of 3-45 t/h and feed sizes up to 50 mm, the MTW series can deliver consistent product quality. For ultra-fine applications (D97 = 5-30 microns), the LUM Ultrafine Vertical Mill integrates grinding, drying, classifying, and conveying into a single compact unit. Its intelligent control system and high fineness output make it ideal for the premium silica powder market.

In some operations, ball mills are still used for coarse grinding or as part of a two-stage process. However, the modern trend in Vietnam is shifting towards vertical roller mills and trapezium mills due to their higher energy efficiency and smaller footprint.

Classification and Dust Collection

After grinding, the powder enters a classifier (integrated or external) to separate oversized particles for recirculation. A bag filter or cyclone collector ensures that the entire system meets strict environmental standards. Zenith’s products come with a mature dust control system, making them ideal for the stringent regulations in Vietnam’s industrial zones.

Recommended Equipment from Shanghai Zenith

Based on decades of experience in the ore grinding industry and a deep understanding of Vietnam’s silica processing requirements, we specifically recommend two models for your milling line:

1. MTW138Z Trapezium Grinding Mill
This model is proven in numerous silica sand plants across Vietnam. With a max feed size of 35 mm and a final product size adjustable from 1.6 to 0.045 mm (10-325 mesh), it offers a capacity of 6-17 t/h. The main motor is 90 kW with a fan motor of 110 kW. Its compact structure and ease of maintenance reduce downtime significantly. For medium-scale producers requiring consistent quality, the MTW138Z is the ideal workhorse.

2. LUM1632 Ultrafine Vertical Mill
For plants targeting the high-value ultra-fine silica powder market (D97 = 5-30 microns), the LUM1632 delivers a capacity of 2.0-13.5 t/h with a main machine power of 280-315 kW. Its roller and grinding table design ensures minimal wear even with abrasive quartz, and the automatic control system reduces labor costs. This mill is particularly suitable for producing silica fillers for plastics, rubber, and premium paints.

Both mills are designed with environmental protection in mind, featuring low noise and efficient dust collection. They have been successfully deployed in several Vietnamese quartz processing facilities, earning high praise for their reliability and performance.
