About Limestone and Grinding Mill

Limestone is a carbonate rock primarily composed of calcite, often accompanied by dolomite, clay minerals, and detrital minerals. It exhibits various colors including gray, black, yellow, light red, or brown-red. Its hardness generally remains low while displaying vigorous reactivity with dilute hydrochloric acid. Limestone is classified as a sedimentary rock based on its origin and represents one of the most widely distributed minerals in the Earth's crust. Based on their depositional settings, limestone can be categorized into marine sediments and continental sediments; the former being more prevalent. According to their origins, limestone can be further classified into three types: biological sedimentary rocks, chemical sedimentary rocks, and secondary rocks. Depending on the varying mineral constituents present within the deposit, limestone can also be subcategorized as siliceous limestone (also known as chert), clayey limestone (also known as marl), and dolomitic limestone.

Limestone Grinding Mill

Currently, there are Raymond mills, high pressure suspension roller mills, Europlate mill, ball mill, vertical mill, ultrafine mill and ultra-fine vertical mill available on the market. These grinding machines belong to different types with varying processing fineness and production capacity. Consequently, their prices also differ. However, they are widely used for limestone processing. Mills are generally classified based on particle size into coarse powder (1-50 mesh), fine powder (50-400 mesh), and ultra-fine powder (400-3000 mesh). Representative mill types for different fineness levels include ball mill, Raymond mill, and ultrafine grinding mill.

Introduction to The Grinding Mill


YGM Raymond Mill

Capacity: 1-50 t/h
Feed Size: 35 mm
Powder Fineness: 80-325 mesh
Raymond mill is composed of the main engine, analyzer, fan, discharge cyclone separator, powder cyclone separator, and air duct. Among them, the main machine consists of a frame, a blower shell, a shovel, a grinding roller, and a grinding ring. It is suitable for processing various non-flammable and explosive mineral materials with Mohs hardness less than 9.3 and humidity less than 6%. It finds wide applications in metallurgy, construction industry chemical industry mining highway construction and other fields. The particle size of the finished powder can be adjusted from 50 mesh to 325 mesh (315-45 microns). Apart from limestone,the processing materials also include quartz feldspar barite calcite carbonate limestone talc ceramics iron ore silicon carbide bauxite phosphate rock coal and approximately 1000 other types of materials.

Mill Advantage

1.  Reasonable structure, small footprint, solid system.
The reasonable structure of the Raymond mill ensures efficient operation and easy maintenance.  Its compact size allows it to be installed in limited spaces without compromising its performance.  The solid system design guarantees stable and reliable operation, providing a strong foundation for the production process.
2.  Compared with other mills, Raymond mill has a high pass rate -99%.
When compared to other milling machines, Raymond mill stands out with its exceptional pass rate of 99%.  This means that almost all materials processed by the mill are finely ground to the desired particle size, ensuring high product quality and minimizing waste.
3.  Adjustable particle size: 80-325 mesh
One of the key advantages of Raymond mill is its ability to adjust the particle size according to specific requirements.  With a range from 80 to 325 mesh, operators have great flexibility in producing materials with different fineness levels for various applications.
4.  The main transmission device of Raymond mill adopts closed gear box and pulley, which ensures smooth transmission and reliable operation.
To ensure smooth transmission and reliable operation, Raymond mill utilizes a closed gear box and pulley as its main transmission device.  This design choice minimizes frictional losses during power transfer while maintaining consistent performance over extended periods of use.
5.  The important parts are made of high-quality castings and profiles to ensure the durability of the entire equipment.
Raymond mill is built using high-quality castings and profiles for critical components such as grinding rollers, grinding rings, blades, etc., guaranteeing their durability even under demanding operating conditions.  This enhances overall equipment longevity while reducing maintenance costs.

Working Principle of Grinding Mill

The centrifugal force generated by the turn plate effectively drives the materials towards the edge, ensuring their entry into the grinding chambers. Once inside, the materials undergo a series of pressing, crushing, and grinding actions from the rollers. This continuous cycle of compression and pulverization further reduces particle size. The finely ground materials then cascade down into multiple layers within the mill, where they undergo additional crushing and grinding until they reach micro powder consistency.
To maintain optimal operation, a high-pressure air blower is utilized to continuously draw air into the fine grinding mill. This airflow carries crushed materials and is directed towards a classifier equipped with a high-speed impeller that screens out particles not meeting desired specifications. Any unqualified particles are redirected back into the mill for regrinding while those that pass through successfully mix with air and enter a cyclone powder collector.
Within this collector, most qualified powders descend downwards and exit through a discharging valve located at its bottom. However, there remains a small proportion of fine powders mixed with airflow that moves towards a dust cleaner unit due to their smaller particle size. These powders adhere to filter bags on its surface. To efficiently remove them from these bags,sudden vibrations are induced by an instantly ejected high-pressure gas controlled by pulse valves.
Finally, after undergoing this intricate process involving various stages and components withinthe system , both batches of mentioned materials are transported via conveyors positioned atthe bottom for packaging as finished powders. Additionally , filtered clean air is emitted from an outlet muffler as partof maintaining environmental standards during operations.
