Raymond Mills

Material: gypsum, calcite, bauxite, talc, limestone, marble, potassium feldspar, dolomite, kaolin, bentonite, wheat meal stone, iron oxide red, granite, iron ore, etc.

Application field: Raymond mill is widely used in calcium carbonate crushing and processing, gypsum powder processing, power plant desulfurization, non-metallic mineral powder making and coal powder preparation.


    With a simple structure and convenient operation, Raymond mills are suitable for processing various non-flammable and explosive minerals with Mohs hardness below grade seven and humidity below 6%. Also, Raymond Mill has the characteristics of low energy consumption and a good grinding effect and is widely used in metallurgy, building materials, the chemical industry, mining, and other fields.

    Working Principle

    Raymond roller mill is mainly composed of main machine, analyzer, blower, finished cyclone separator, pipeline device, motor, etc. The auxiliary equipment includes Raymond mill, dustpan elevator, electromagnetic vibrating feeder, electric control cabinet and other components. The Raymond mill crushes large raw materials into the desired particle size and is then transported to the storage bin through an elevator.

    Subsequently, the vibrating feeder evenly feeds the material into the grinding chamber. The material is ground between the grinding rollers and the grinding ring, and the fan brings the powder to the analyzer for classification. The fineness of the powder meets the requirements, enters the large cyclone collector through the pipeline for separation and collection, and finally discharges the finished product.

    The shovel system is key in the main machine's working process. Blade scoops up the material and throws it into the gap between the grinding roller rings to form a cushion layer. So, the material is crushed by the extrusion force of the rotating grinding roller to achieve the goal of crushing.


    Raymond Mill Adopts Vertical Structure with Strong System
    The raymond mill machine features a compact vertical structure, occupying minimal space while boasting a robust system. It seamlessly transitions from raw material processing to powder production, culminating in final packaging, thereby forming a self-sufficient and comprehensive production system.
    Effective Separation of the Required Powder
    Compared with other grinding equipment, the through-screening rate of raymond grinding mill is up to 99%.
    Stable and Reliable Operation of the Equipment
    The mainframe transmission device of Raymond mill adopts sealed gearbox and belt pulley to ensure the smooth and reliable transmission of the equipment, making it more reliable to use.
    Adopting High Quality Materials and Advanced Industrial Design
    The important parts of our Raymond mills are all made of high-quality castings, which are finely crafted to ensure the durability of the machinery and equipment.
    Unmanned Operation, and Efficient Operation
    The electrical system of the grinding plant adopts centralized control, which makes the plant unmanned and more convenient for maintenance.
    Convenient Maintenance
    It’s easy to maintain. The parts are easy to replace, which reduces the downtime and maintenance costs.
