It is usually made of cast steel and has a smooth and durable surface. The grinding table is responsible for the grinding process and supports the grinding rollers. Grinding Rollers: The grinding rollers are a set of cylindrical rollers that exert pressure on the material on the grinding table. They rotate at a specific speed and crush the material by applying force and friction. The number and size of the grinding rollers can vary depending on the mill design and capacity. Grinding Wheel: The grinding wheel is the main component responsible for the grinding action in a vertical roller mill. It is mounted on the grinding table and rotates along with it. The grinding wheel is usually made of durable materials such as alloy steel or cast iron and is equipped with grinding segments or tires that crush and grind the material. Nozzle Ring: The nozzle ring is located around the grinding table and is responsible for distributing the material evenly onto the grinding table. It directs a controlled airflow and acts as a classifier, separating fine particles from coarse particles. The nozzle ring also helps to stabilize the grinding bed and maintain the desired grinding efficiency. Mill Housing: The mill housing encloses all the internal components of the vertical roller mill. It provides support and protection for the grinding table, grinding rollers, and other critical parts. The mill housing is designed to withstand the forces generated during the grinding process and to prevent leakage of material or air. Drive System: The drive system consists of the motor, gearbox, and auxiliary equipment that transmit power to the grinding table and rollers. The motor provides the necessary rotational power, while the gearbox converts and regulates the speed of rotation. The drive system is crucial for maintaining the desired grinding speed and controlling the mill operation. Separator: The separator is an essential part of the vertical roller mill and is responsible for separating the fine and coarse particles after grinding. It uses centrifugal force to separate the material, ensuring that only the desired product fineness is collected while the coarser particles are recirculated back to the grinding table for further grinding. Mill Fan: The mill fan is used to transport the pulverized material and the gas or air stream generated during the grinding process. It creates the necessary airflow within the mill, ensuring efficient operation and proper ventilation. The mill fan also helps to cool down the grinding components and remove excess moisture from the material. Ductwork and Cyclone: The ductwork and cyclone system are used to transport the pulverized material and the air stream from the mill to the product collection point. The ductwork directs the material and air through a series of pipes and channels, while the cyclone separates the fine particles from the air stream, allowing them to be collected in a product container or storage facility. These are the main parts of a vertical roller mill. Each component plays a crucial role in the grinding process and contributes to the overall efficiency and performance of the mill.
