As one of the provinces with the richest limestone resources in China, the quicklime industry in Shanxi is undergoing a profound transformation from traditional extensive development to high-end refined production. In recent years, with the advancement of the "double carbon" goal and the release of green transformation demands in the building materials industry, the application of quicklime in fields such as new-type wall materials, environmental protection coatings, and high-performance concrete has grown rapidly.

With the tightening of environmental protection policies, traditional lime powder enterprises in Shanxi are facing the pressure of eliminating high-energy consumption and high-pollution equipment, and energy-saving and environment-friendly modern powder making equipment has become a necessary demand for industrial upgrading. In this transformation wave, relying on mature technology and strong stable performance, SBM MTW European trapezium mill has become a powerful engine for Shanxi lime enterprises to improve quality and efficiency.

Quicklime Grinding Production Line in Shanxi
A building materials enterprise located in Shanxi has long supplied quicklime raw materials to surrounding cement plants and new-type wall materials enterprises. In response to the dual pressures of intensified market competition and downstream customers' requirements for product fineness, the customer decided to phase out the original old Raymond mill equipment and shift to an intelligent and large-scale production model. After multiple rounds of technical demonstration and supplier inspection, it finally chose to cooperate with SBM.

Material: Quicklime
Fineness: 200 mesh
Application of finished product: Building materials field

Equipment: MTW European trapezium mill
The technical team of SBM conducted an in-depth on-site survey, covering aspects such as plant space layout, raw material characteristics, and power supply configuration. Based on the actual situation, they tailored a production line layout plan for the user and selected the MTW European trapezium mill as the main equipment for the project.
The MTW European trapezium mill has become the preferred equipment in the field of quicklime processing in Shanxi Province due to its multiple core technological advantages. Equipped with a curved shovel design, bevel gear transmission, and an intelligent control system, the equipment can efficiently and stably process hard materials such as limestone, meeting the stringent requirements of the building materials industry for powder uniformity and particle size distribution.
Technical Highlights of MTW European trapezium mill

Technological iteration, mature and stable equipment: With nearly 40 years of experience in mill manufacturing, SBM has achieved four generations of upgrading and iteration of grinding mills. It boasts leading-edge technology and ensures stable operation of equipment.
Special grinding design for high grinding efficiency: The curved shovel design is adopted to increase the grinding area of materials and improve the grinding efficiency.
Bevel gear integral transmission for reduced energy consumption: The bevel gear integral transmission and non-resistance air inlet volute design are applied, which enable better material fluidity and lower energy consumption.
Oil lubrication for extended bearing life: Both the main shaft transmission system and the fan transmission system of the equipment adopt oil lubrication. Compared with the traditional grease lubrication method, it features smaller lubrication resistance and lower oil temperature, which can effectively extend the service life of bearings.
New frequency conversion powder separator for high precision of finished products: A new hanging cage-type powder separator is used, with frequency conversion control. The fineness is adjustable and controllable, meeting the requirements of various specifications and particle sizes.

Since the production line was put into operation, the grinding system with professional technology from SBM has shown extremely stable and efficient performance:
Stable and up-to-standard production capacity: The equipment continuously processes quicklime at a stable capacity of 15 tons per hour, with precise fineness and excellent quality of finished products.
Significant operational economy: The system design of the MTW European trapezium mill has significantly improved the comprehensive energy efficiency, leading to a substantial increase in economic benefits.
Improved production environment: The entire line features excellent sealing performance, and combined with the efficient negative pressure dust collection design, it effectively controls dust emission.

The successful application of SBM MTW European trapezium grinding mill in the Shanxi quicklime project not only verifies SBM strong capabilities in fineness control, energy efficiency management, and environmental protection performance, but also highlights the enterprise's "customer-centric" service philosophy. From early demand diagnosis to later operation and maintenance support, SBM helps customers achieve a leap from "equipment procurement" to "value creation" through full-life-cycle management.
