Product Description
The Raymond Grinder, or Raymond Mill, is a versatile tool designed to pulverize a variety of materials including barite, calcite, potash feldspar, talcum, marble, limestone, and slag-all with a hardness below scale 7 on the Moh's scale. It is perfectly suited for non-flammable and non-explosive substances across 280 different types. This equipment plays a crucial role in multiple industries such as mining, building materials, chemical engineering, and metallurgy, particularly for power generation and processing.
Our grinder offers an impressive range of adjustable product sizes, meticulously tailored to your requirements, spanning from 80 to 425 meshes. Additionally, it can finely process certain materials to an extraordinary 2,000 mesh level, catering to diverse industrial applications.
Core Principles of Operation
The process begins by evenly and consistently loading materials into the grinding chamber of the main frame. As the machine rotates, centrifugal force propels the roller outward, applying pressure against the ring. A shovel strategically positioned within the system transports the materials into the space between the roller and the ring, where the rolling motion of the roller effectively grinds the material to the desired fineness.

Streamlined Milling Production Line
The production process starts with material comminuted by a jaw crusher, which is then elevated to a storage silo. An electromagnetic vibrating feeder consistently delivers the material to the host for grinding. The finely ground powder is separated by a polishing powder separator, then transported by airflow to storage silos, where it is eventually discharged through the outlet valve.
Our entire production workflow operates under negative pressure. Initially, an external fan directs air mixed with powder through pipes to the storage silo's cyclone collector at the top. This air is recirculated back by the blower pipe, enhancing process efficiency. The bottom lock powder feeder separates external positive pressure gas from the negative pressure environment, significantly boosting yield. Moreover, any residual air and dust from the host are filtered in a baghouse, ensuring environmental safety by capturing impurities.
This cutting-edge mill is predominantly utilized in industries such as metallurgy, building materials, chemicals, and mining, effectively processing minerals with a Moh's hardness below 9.3 and humidity under 6%. It grinds a wide array of non-flammable mineral materials, including quartz, feldspar, calcite, talcum, barite, fluorite, rare earth, marble, ceramics, bauxite, manganese ore, iron ore, copper ore, phosphate rock, iron oxide red, zircon sand, and slag.
