Limestone Grinding and Processing

Limestone grinding processing is a key industrial production process, its main purpose is to grind limestone raw materials into fine powder to meet the needs of different industries. Suitable grinding equipment can improve production efficiency, reduce energy consumption, and ensure product quality. This process is widely used in many aspects such as the construction industry, chemical industry, and environmental protection fields, and has contributed to the sustainable development of society.

Processing scheme

Large pieces of limestone are broken into particles suitable for entering the grinding mill through the crusher. The feed fineness at this stage is generally controlled between 15 mm and 50 mm. Commonly used crushing equipment include jaw crushers, cone crushers, etc.
Grinding is to feed the crushed limestone small pieces into the grinding mill, and grind them into fine powder through the interaction of the grinding roller and the grinding ring. Common grinding equipment include Raymond mill, vertical mill, etc.
The limestone powder after grinding needs to be graded by vibrating screen or classifier. The unqualified powder after grading is returned to the motor of the mill through the pipeline to be regraded until it reaches the required powder particle size.
Limestone powder that meets the fineness enters the dust collector with the air flow for separation and collection. After screening and dust removal, the limestone powder passes through the discharge port and is sent to the finished product silo by the conveying device.
