Autoclaved Aerated Concrete (AAC) blocks boast outstanding properties: a density of only 300-700kg/m³, low thermal conductivity and a compressive strength of 4.5MPa, gaining wide popularity in the building enclosure market. Limestone powder serves as a primary and alternative admixture for cement products, which has greatly increased the demand for limestone powder in AAC manufacturing plants.
In the core formula of AAC blocks, the fineness, purity and whiteness of limestone powder directly determine the block's strength, impermeability and shrinkage control performance. Limestone fine powder needs to be ground to 200-400 mesh to fully participate in hydration reactions and form stable calcium silicate hydrate gel, ensuring the compressive strength and durability of AAC blocks.
To meet the demands for large-scale, refined and energy-saving AAC block production lines, Zenith recommends three core models: LM Vertical Roller Mill, MTW European Trapezium Grinding Mill and XZM Ultrafine Grinding Mill. They deliver fully adaptable professional solutions for limestone fine powder processing, helping AAC block plants cut costs, improve efficiency and upgrade product quality.
Three powerful grinding mills perfectly cater to all application requirements of AAC production.
We offer three flagship models: LM Vertical Roller Mill, MTW European Trapezium Grinding Mill and XZM Ultrafine Grinding Mill, covering full particle size processing from coarse powder to ultrafine powder for AAC blocks.
LM Vertical Roller Mill: The All-round Core for Large-scale Production
As the preferred equipment for large AAC block production lines, LM Vertical Roller Mill integrates crushing, drying, grinding, classification and conveying, providing an efficient and compact solution for limestone pulverization.
Capacity & Fineness Adaptation: It meets the particle size requirements of limestone fine powder for AAC blocks and satisfies the production capacity of large-scale AAC manufacturing bases.
Outstanding Process Advantages: Hot air makes direct contact with materials inside the mill for powerful drying performance, eliminating the need for separate dryers. This simplifies processes and cuts infrastructure investment. The grinding rollers and rings are made of high-wear-resistant alloys, featuring high grinding efficiency. The finished powder has uniform gradation and higher activity, effectively improving the strength of AAC blocks.
MTW European Trapezium Grinding Mill: High-efficiency Benchmark for Medium & Small Capacity
Tailored for the fine pulverization needs of medium and small-sized AAC block plants, the MTW European Trapezium Grinding Mill features proven stability, outstanding energy efficiency and easy maintenance, making it a cost-effective option for limestone fine powder processing.
Optimized for AAC Production: It flexibly adapts to the capacity plans of medium and small AAC production lines. With precise fineness adjustment, the finished powder boasts good uniformity and low impurity content, complying with batching standards without secondary screening.
Core Technological Advantages: The curved scooping blades expand the grinding area. The integrated bevel gear drive features a compact structure and small footprint to reduce infrastructure costs. Equipped with a full thin oil lubrication system, the equipment achieves excellent heat dissipation and low wear. Key components allow maintenance without shutdown, greatly cutting operational and maintenance expenses.
XZM Ultrafine Grinding Mill: Custom Expert for High-end Ultrafine Powder
Developed to meet the demand for ultrafine limestone powder in high-grade AAC blocks, the XZM Ultrafine Grinding Mill specializes in ultra-fine grinding and delivers customized powder solutions.
Superior Ultrafine Grinding Performance: The finished powder features narrow particle size distribution and large specific surface area with remarkably enhanced activity. It accelerates the hydration reaction of AAC blocks, shortens autoclave curing time, and improves the thermal insulation and compressive strength of finished products.
Precision Grinding Structure: Fitted with multi-layer grinding rollers and high-precision classifier wheels. The well-sealed structure prevents impurity contamination and guarantees high purity of limestone powder, fully complying with production standards for high-end AAC blocks.
Versatile Application: Compact and easy to install. It can work independently for small high-end AAC production lines or serve as an auxiliary ultrafine grinding unit for large-scale lines, catering to the production of AAC blocks of various specifications and grades.
Covering large-scale mass production, refined processing for medium and small capacities, and customized production of high-end ultrafine powder, the three grinding mills form a complete limestone fine powder processing portfolio, fully accommodating AAC block plants' diverse requirements in production capacity, product quality and budget.
Choosing professional limestone fine grinding equipment means securing reliable quality and efficiency for AAC block production. Featuring proven technology, stable performance and customized services, Zenith's three series of grinding mills help AAC block plants build efficient, energy-saving and eco-friendly modern production lines, and drive high-quality development of the green building materials industry.
