Cronus Calcium hydroxide special grinding machine successfully installed in Anning, Yunnan, boosting industrial upgrading
On March 31, 2025, Anning, Yunnan – Cronus, a global leader in powder equipment, completed acceptance and put into production its CRHG series calcium hydroxide special grinding mill at an environmental protection material enterprise in Anning, Yunnan (not disclosed at the request of the customer).It has injected strong impetus into the development of local calcium hydroxide related industries.

Customized solutions that directly address industry pain points
The CRHG series calcium hydroxide special grinding mill is incomparable to ordinary grinding mills. It is the result of Cronus’s careful research and development based on a lot of in-depth market research and user demand insights. Cronus works closely with many calcium hydroxide manufacturers.
Fully consider the unique physical and chemical properties of calcium hydroxide powder and gray calcium powder. Calcium hydroxide materials have special hardness, particle size requirements and chemical reactivity, and ordinary grinding mills cannot meet their precise processing needs at all.


In view of these characteristics, Cronus’s R&D personnel have made special optimizations from the selection of grinding parts of the grinding mill, to the sophisticated design of the overall structure, to the reasonable configuration of the power system, to ensure that the calcium hydroxide raw materials can be efficiently and stably converted into high-quality powders that meet the strict requirements of various application scenarios. This achievement is not only a concentrated display of Cronus’s years of industry technology accumulation and experience precipitation, but also a vivid example of the company’s consistent adherence to the deep integration of technological innovation and user demand-oriented concepts.
CRQ production line builds a complete calcium hydroxide processing ecosystem
The Calcium hydroxide special grinding mill for calcium hydroxide is very different from the ordinary grinding mill. It is the result of Cronus’s careful research and development after a lot of in-depth market research and full insight into user needs. Cronus has worked closely with many calcium hydroxide manufacturers. In the research and development process, it fully considered the unique physical and chemical properties of calcium hydroxide powder and gray calcium powder.
Calcium hydroxide materials have special requirements in terms of hardness and particle size, and have specific chemical reactivity. Ordinary grinding mills cannot achieve accurate processing of them at all. In view of these characteristics, Cronus’s R&D personnel have carried out targeted optimization from the material selection of the grinding parts of the grinding mill, to the ingenious design of the overall structure, to the reasonable matching of the power system.


In this way, calcium hydroxide raw materials can be efficiently and stably processed into high-quality powders that meet the stringent requirements of various application scenarios. This achievement is not only a concentrated reflection of Cronus’s accumulation of technology and experience in the industry over the years, but also a vivid portrayal of the company’s deep integration of technological innovation and user-oriented concepts.
CRQ Calcium Hydroxide Production Line: Integrated Intelligent Grinding System
The grinding mill is one of the core equipment of the CRQ calcium hydroxide production line. The CRQ calcium hydroxide production line is scientifically composed of four parts: CRSH series lime digester (dynamic digestion), delayed digestion bin (static digestion), CRHG series calcium hydroxide special grinding mill, and CRXF series calcium hydroxide powder selector.
Based on the overall investment budget of local enterprises in Yunnan, the actual floor area of the plant, the total energy consumption control target, the quality characteristics of raw materials, the operating cost planning, and the competitive advantages that products need to have in different application fields, Cronus has tailored a unique production process and construction plan for them.
The entire production line adopts advanced technology and processes, which truly achieves energy conservation, environmental protection and intelligent control. With the help of an intelligent control system, it can accurately monitor and flexibly adjust various key parameters in the production process in real time, which not only effectively improves product quality, but also reduces operating costs. It is an efficient and green intelligent production line for calcium hydroxide powder.
The production capacity of the CRQ calcium hydroxide production line is between 5 and 30t/h, and its application scenarios are very wide. In Anning, Yunnan, the local construction industry is developing rapidly. As an important additive for building materials, calcium hydroxide can significantly enhance the adhesion and durability of materials, and plays a key role in improving the quality of buildings. At the same time, as environmental protection requirements become more stringent, in the field of sewage treatment, calcium hydroxide can effectively remove harmful substances in sewage, so that water quality meets the discharge standards, and contribute to the protection of the local ecological environment.
The successful installation of the Cronus calcium hydroxide mill will greatly meet the demand for high-quality calcium hydroxide products in related industries in Anning and surrounding areas, effectively promote local industrial upgrading, and promote the coordinated and sustainable development of the economy and the environment.
