Limestone Introduction

Limestone is a unique mineral resource. It is widely used in industry. Its excellent properties make it an ideal choice for foundry sand. Among many applications of limestone, Portland cement is one of the most typical uses. According to data, the demand for limestone in the cement industry reaches about 29 billion tons, which fully illustrates the importance of limestone in the industrial field. MGW limestone Raymond mill, as a typical high-efficiency grinding equipment, can grind limestone blocks into powder with its unique processing principle and significant advantages, making it the best choice for limestone powder making in the industrial field.

Working Principle

The grinding and powdering process of MGW limestone Raymond mill involves multiple links. This MGW grinder production plant is composed of crusher, bucket elevator, storage bin, belt feeder, main grinding machine, pipeline, cyclone powder collector, pulse dust collector, etc.

The first is the crushing stage. The limestone stones are fed into the crusher for crushing. The crushed limestone stones are sent to the storage bin through the elevator and then enter the grinding mill through the feed port. This is the most important grinding stage. After the crushed limestone stones enter the main grinder, they are continuously scooped up by the shovel and transported between the grinding ring and the grinding roller. The grinding ring and the grinding roller continuously roll, squeeze and impact the limestone stones. During this period, the limestone will be gradually ground into limestone powder. The crushed limestone powder rises to the classifier under the action of airflow, and the classifier separates the air and powder. After screening by the classifier, the qualified powder will be sent to the cyclone powder collector through the pipeline for powder collection, which is the finished powder. Powders with larger particle sizes cannot pass through the powder classifier and will return to the main grinding machine for grinding again until they meet the qualified particle size requirements.
