Raymond Grinding Mill
The Raymond grinding mill is a vertical roller grinding equipment, widely used in the processing of non-flammable and non-explosive minerals with a Mohs hardness of ≤7 and a humidity of below 6%. It can adjust the fineness of 80-325 mesh (special models can reach 500 mesh), and is a revolutionary alternative to traditional ball mills.
Capacity: 1-25 T/H
Feeding Size: <40mm
Discharge Size: 0.045-0.6mm
Process Material: The material below scale 6 of Mohs hardness and 250-odd sorts of non-inflammable and non-explosive stuff for high fine powder generation and processing, such as talcum, barite, marble, limestone, charcoal blacks.
Raymond Grinding Mill Overview
The Raymond grinding mill Machine is mainly suitable for the processing of materials in the building materials, chemical industry, metallurgy, mining, abrasives, refractory materials, ceramics, iron and steel, electric power, coal, and other industries. It can grind quartz stone, barite, fluorite, rare earth, marble, ceramics, iron ore, copper ore, phosphate rock, slag, water slag, cement clinker, activated carbon, dolomite, granite, coking coal, lignite, diamond Beautiful sand, chrome oxide green, gold ore, red mud, clay, kaolin, coke, coal gangue, china clay, fluorspar, bentonite, diabase, pyrophyllite, phyllite, basalt, gypsum, graphite, silicon carbide, thermal insulation materials Various non-flammable and non-explosive mineral materials with Mohs hardness below 9 and humidity below 6%.
Advantages
Raymond Grinding Mill Advantages
The raymond grinding mill offers multiple advantages, including a long service life through its resilient coupling that minimizes vibration and noise, along with a simple yet compact system design that allows for space-saving outdoor arrangements to significantly reduce investment costs. It features high-performance sealing technology, an eco-friendly air circulation system paired with an advanced dust remover for environmental compliance, and energy-efficient operation. Additionally, its convenient impeller adjusting devices enhance the precision of finished products, ensuring optimal performance and quality.
✔ Efficient grinding and particle size adjustment: The high-pressure spring system is used to enhance the grinding roller pressure (800-1200kg), and the closed-circuit air selection cycle is used to achieve 80-425 mesh particle size adjustment, and some models can reach more than 1000 mesh.
✔ Stable operation and low noise: The whole machine adopts a three-point positioning structure to reduce vibration, the noise is as low as 60 decibels, and the operation stability is high.
✔ Strong adaptability: It is suitable for non-flammable and explosive materials with a humidity of less than 6% and a Mohs hardness of no more than 9.3, and can directly process raw materials below 20 mm.

Structures & Working Principle
Raymond Grinding Mill Structure
The main parts of a Raymond grinding mill plant are a cyclone collector, pipe fittings, dust collector, storage hopper, elevator, crusher, electric control cabinet, feeder, main plant, blower, separator, etc.,

Raymond Grinding Mill Working Principle
After the bulk material is crushed to the required particle size by the jaw crusher, the material is sent to the storage hopper by elevator, and then the material is continuously fed in evenly and quantitatively through the vibrating feeder Grinding in the main machine grinding chamber, the ground powder is taken away by the airflow of the fan, and classified by the analyzer. The fineness of the powder enters the large cyclone collector through the pipe with the airflow for separation and collection, and then the powder is discharged The valve discharge is the finished powder. The airflow is sucked into the blower by the return duct at the upper end of the large cyclone collector. The entire airflow system of this machine is closed and circulating, and it circulates under the condition of positive and negative pressure.
