Rayong, Thailand, has emerged as a key industrial hub in Southeast Asia, with a growing demand for high-performance thermal insulation materials in construction. One critical component driving this demand is the processing of fly ash into ultra-fine powder for use in thermal insulation mortar. At Shanghai Zenith Machinery Co., Ltd., we understand the unique challenges of this application and have tailored our HGM110 ultrafine grinding mill to meet the exacting specifications of 1150 mesh fly ash production. This article explores how our advanced technology addresses the needs of manufacturers in Rayong, offering efficiency, reliability, and superior product quality.

Addressing the Thermal Insulation Mortar Requirement

Thermal insulation mortar requires a precise particle size distribution to ensure optimal bonding, workability, and insulating properties. Fly ash, when ground to 1150 mesh (approximately D97 < 10 microns), acts as an excellent filler and pozzolanic material, enhancing the mortar's thermal resistance and mechanical strength. Our HGM110 mill, part of the XZM series ultrafine grinding technology, is specifically engineered to produce powders from 325 mesh up to 3250 mesh with single classification. This makes it ideal for achieving the consistent 1150 mesh target demanded by Rayong's construction sector.

Unlike conventional mills that may struggle with uniformity or energy consumption, the HGM110 incorporates a variable frequency drive (VFD) classifier. This allows operators to adjust the rotor speed easily via an electric control panel, ensuring precise control over finished product fineness. For a thermal insulation mortar plant in Rayong, this means reduced variability and higher batch-to-batch consistency.

Why Choose HGM110 for Fly Ash Processing?

Fly ash is inherently abrasive and variable in composition. The HGM110 ultrafine grinding mill is built to handle such materials with robust design and advanced engineering. Key features include:

• Arbitrary Adjustment of Fineness: With the ability to adjust product fineness between 325 and 2500 mesh, and achieve D97 < 5 micron at one time, the mill provides flexibility for different mortar formulations.
• High Efficiency, Low Energy Consumption: Compared to air-flow mills or stirring mills, the HGM110 boasts 40% higher efficiency and 70% lower energy consumption under the same power conditions. This is a critical advantage for manufacturers in Rayong looking to reduce operational costs.
• Safe Structural Design: The grinding chamber contains no rolling bearings or screws, eliminating common failure points such as bearing leakage or screw loosening. This translates to less downtime and lower maintenance costs.
• Simplified Maintenance: The VFD classifier and straightforward inner structure make routine checks and replacements straightforward, ideal for plants where skilled technicians may be limited.

Working Principle Tailored for Fly Ash

The HGM110 operates under a well-proven principle: crushed fly ash is fed into the main machine, falling onto a rotating turntable where grinding rollers crush it under centrifugal force. The material then enters the classifier with airflow; unqualified particles are returned for re-grinding, while qualified powder is collected in a cyclone and pulse dust collector. The entire system operates under negative pressure, ensuring no dust spillover—an important environmental consideration for Rayong's industrial zones.

This closed-loop design not only meets Thai environmental standards but also enhances product purity by effectively removing iron impurities and oversized particles. The result is a consistent 1150 mesh fly ash powder that performs reliably in thermal insulation mortar applications.

Industry-Leading Energy Savings and Capacity

Our HGM110 offers a capacity range of 0.5-25 T/H, making it suitable for both small-scale pilot plants and large commercial operations. For a typical fly ash grinding line in Rayong targeting 1150 mesh, the mill can achieve throughputs that justify the investment while keeping energy costs low. The 70% reduction in energy consumption compared to traditional mills is particularly beneficial in regions where electricity prices are a significant factor.

Furthermore, the mill's compact footprint—requiring no additional foundation or extensive civil works—allows for easy integration into existing plants. This is a key advantage for Thai manufacturers seeking to upgrade their processing capabilities without major capital expenditure on infrastructure.
