How many meshes can a stone mill reach?

In industries such as mining, metallurgy, chemical industry, and building materials, grinding equipment plays a vital role. As one of the important equipment in these industries, the performance, efficiency, and finished product fineness of the stone mill has always received widespread attention. This article will introduce in detail the types, working principles, finished product fineness, and advantages of stone mills in industrial applications.

What are the stone mills?

There are many types of stone mills, including Raymond mills, roller mills, and ultrafine vertical mills. Each mill has its unique characteristics and scope of application:

Raymond mill is an efficient powder-making equipment that replaces ball mills to process ore powder. Its grinding fineness is usually between 80 and 500 meshes, and the hourly output ranges from a few tons to 30 or 40 tons. Raymond mills are widely used in mining, building materials, metallurgy, and chemical industries, and they are suitable for the powder-making of non-flammable and explosive materials with a Mohs hardness of no more than 7 and a humidity of less than 6%.

Vertical mill: A vertical mill is ideal large-scale grinding equipment with fineness between 120 and 325 meshes and an output ranging from several tons to dozens of tons. Ultrafine vertical mills are widely used in industries such as cement, electricity, metallurgy, the chemical industry, and non-metallic minerals. They have the characteristics of integrated crushing, drying, grinding, grading, and conveying and high production efficiency.

Ring roller mill: The ring roller mill's grinding fineness range is wider, ranging from 200 mesh to 600 mesh, and the output ranges from several tons to dozens of tons. This mill is mainly used for crushing brittle materials with a hardness of no more than level 5, such as heavy calcium (calcite, marble, dolomite, etc.), barite, phosphate rock, etc.

How does the stone mill work?

The working principle of the stone mill mainly depends on the rotation of the grinding disc and the pressure between the grinding discs. The equipment is usually composed of the main machine, reducer, screw conveyor, and powder screening machine. The main machine is the core component of the mill, which consists of a turntable, a grinding shell, and bearings. The grinding head on the turntable rotates on the bearing to generate grinding force. The reducer provides power and adjusts the speed of the main machine. The screw conveyor transports the stone to be ground into the grinding disc, and the grinding head grinds the stone into powder. The powder is screened by the powder screening machine, and the large particles of powder are put into the grinding disc again until the required fineness is reached.

How many meshes can the stone mill reach?

The fineness of the stone mill's finished product is wide, depending on the type of mill selected. The suitable grinding fineness of the Raymond mill is between 80 and 400 mesh; the fineness of the vertical mill is as high as 120 to 325 mesh; and the grinding fineness of the ring roller mill is between 200 mesh and 600 mesh. In addition, some ultra-fine grinding mills can meet the production needs of different industries with higher fineness requirements.

Summary

As an important equipment in the mining, metallurgy, chemical industry, and building materials industries, the stone mill has a wide variety, advanced working principles, and a wide range of finished product fineness. Different types of grinding mills, such as Raymond mill, roller mill, and vertical mill, have their characteristics and are suitable for materials of different hardness and moisture. Through advanced grinding technology and an efficient screening system, stone grinding mills can produce powder products with uniform fineness and stable quality.

When choosing a stone grinding mill, it is recommended to consider factors such as specific production needs, material characteristics, and budget.
