The background of the limestone processing project in Yunnan

In Yunnan, China, a large private building materials enterprise takes limestone and cement as its industrial chain. In recent years, the development of infrastructure construction and real estate has increased the market demand for high-quality building materials, putting forward higher standards for the quality and performance of cement, lime, etc. The traditional production methods have deficiencies in resource utilization efficiency and environmental protection, and it is difficult to meet the requirements of regulations and sustainable development. In order to improve efficiency and ensure quality, the enterprise has decided to introduce advanced technologies and equipment.

The CRRM1850 Raymond Mill Facilitates the Limestone Processing Project

Among numerous equipment selections, the CRRM1850 Raymond mill has become the core equipment of the project.

Key parameters: maximum feed particle size is 30mm, hourly capacity is 6.5 - 30 tons, fineness can be processed to 40 - 400 mesh, which can meet the needs of different downstream products.

Processing process: large pieces of limestone are fed into the crusher by a vibrating feeder and crushed to 30mm, then lifted to the storage hopper by an elevator, and then sent to the grinding chamber of the Raymond mill main unit by a belt conveyor to be ground into fine powder. After grinding, the material is classified by the powder separator under the action of the fan. Unqualified coarse particles return to the grinding chamber, and qualified fine powder enters the cyclone powder collector through the air chute for separation. The collected material is discharged through the discharging device to form powder.

Advantages of the CRRM1850 Raymond Mill in processing limestone

High efficiency and energy saving: Adopting advanced technologies and energy-saving designs to reduce energy consumption, improve grinding efficiency, save production costs, and the energy consumption can be reduced by approximately 20% - 30%.

High product fineness: The fineness range is 40 - 400 mesh, with precise control. The powder selection system has high - efficiency classification to meet high - end application requirements.

Simple structure: With a concise design and a reasonable layout, it is easy to install and maintain, has a low failure rate, and is easy to repair.

Wide application range: It can efficiently grind a variety of non - metallic minerals, with strong versatility and adaptability.

Low maintenance cost: The vulnerable parts are made of high - performance wear - resistant materials, which have a long service life and simple daily maintenance.

Good environmental performance: Adopting a closed - loop circulation system and equipped with a pulse dust collector, the dust emission meets the standards, protecting the environment and the health of workers.

Strong systematicness: All links are closely connected to form an efficient production system, which is convenient for centralized control and management.

Feedback from Customers of Limestone Processing Project

Performance data: At the completion and acceptance of the project, the hourly output of the crushing system is 60 tons, and the hourly output of the grinding system is 15 tons. The quality of the limestone powder meets the technical agreement, with uniform particle size and stable chemical composition.

Customer praise: Customers praise the project for its concise and reasonable design, smooth and efficient process; compact equipment layout, space-saving, and convenient operation; proper environmental protection measures, achieving a win-win situation of economic and environmental benefits; stable equipment operation and significant energy-saving effect.

Summary

In the limestone processing project of this enterprise in Yunnan, the CRRM1850 Raymond mill has performed outstandingly, helping the enterprise improve efficiency, ensure quality, and achieve green and energy - saving production. With the continuous development of the industry and the increasing demand for mineral powder, the CRRM1850 Raymond mill is applied in more projects, contributing to the development of the industry.
