Fineness: 325 to 1500 mesh, capable of meeting the needs of various industries.

Particle size distribution D97:10 - 45±1, 97% of the particle size is between 10 - 45 micrometers, with an error margin of ±1 micrometer.

Application Areas: Ultrafine powders are widely used across various industries. In the papermaking industry, they can enhance the whiteness and other properties of paper. In the plastics industry, adding talc powder and other materials can strengthen the durability and corrosion resistance of pipes. In the coatings industry, utilizing ultrafine titanium dioxide and other pigments can improve the hiding power and other characteristics. For rubber products such as tires, the addition of silica and other materials significantly enhances strength and wear resistance while reducing rolling resistance.

Main Structure of CRLMX Superfine Vertical Grinding Mill

Grinding Disc: Fixed to the output shaft of the reducer, it is made of high-strength wear-resistant material with a special wear-resistant lining on the surface. Driven by the motor, the reducer causes the grinding disc to rotate at high speed, generating centrifugal force. This force moves the material towards the edge, where it undergoes friction with the grinding disc and is crushed by the grinding rollers.

Grinding rollers: Symmetrically distributed around the center of the grinding disc, these rollers are made of high-performance wear-resistant materials. Driven by a hydraulic system, they crush materials. The hydraulic system can precisely control pressure, working in coordination with the grinding disc to regulate pressure through components such as oil pumps, hydraulic cylinders, and accumulators.

Separator: The airflow carries the material to the separator. The coarse powder is thrown against the outer wall and falls back onto the grinding disc, while the fine powder passes through the gaps between the vanes and enters the collection device. Adjusting the rotational speed can control the fineness.

Hydraulic System: Responsible for adjusting the pressure of grinding rollers, it consists of an oil pump, oil cylinders, hydraulic valves, accumulators, and other components. The workflow involves the oil pump supplying oil, the oil cylinders driving the grinding rollers, the hydraulic valves controlling the flow of hydraulic fluid, and the accumulators stabilizing the pressure. Pressure adjustment significantly affects the grinding performance for different materials.

Transmission system: Composed of an electric motor, reducer, coupling, and other components, it serves as the core of power transmission. The motor power is reduced in speed and increased in torque by the reducer, then transmitted to the grinding disc through the coupling. This setup operates efficiently and stably, effectively reducing vibration and noise.

Environmental Protection Design: The product adopts a sealed structure and soundproofing materials. The shell is fully sealed, and the connection points are specially treated to prevent dust from spilling out. Multiple layers of soundproofing materials are used to reduce noise, meeting environmental protection requirements.

Working Principle of CRLMX Superfine Vertical Grinding Mill

Feeding Stage: The raw material is transported to the center of the grinding disc through the feeding device. Under the action of centrifugal force, it moves towards the edge, forming a material flow and preparing for grinding.

Grinding Stage: The lamination crushing principle is adopted, where grinding rollers press the raw material under hydraulic or spring pressure. The hydraulic system precisely controls the pressure, and the lamination crushing enhances the crushing efficiency while reducing wear on components.

Sorting Stage: The airflow carries the finely ground powder to the classifier, which operates based on the principles of centrifugal force and aerodynamics. The coarse powder falls back onto the grinding disc, while the fine powder enters the collector. The particle size of the finished product is controlled by adjusting the rotational speed of the classifier and the airflow rate.

Collection Stage of Finished Products: Fine powder enters the dust removal system with the airflow, where cyclone separators and bag filters separate the fine powder. The waste gas is purified before being discharged, ensuring product quality and environmental protection

Characteristics of CRLMX Superfine Vertical Grinding Mill

Low Construction Costs: Compared to the ball mill system, the footprint is reduced by approximately 50%, and construction costs are cut by about 70%. The integrated design simplifies the system structure, reduces the need for auxiliary equipment and infrastructure, and allows for open-air installation.

Low Operating Costs: The high grinding efficiency reduces power consumption by 40–50%. The wear-resistant components are made of high-chromium wear-resistant material, ensuring a long service life. The external circulation device optimizes the material circulation path, further lowering power consumption.

Reliable Operation: The automatic control system monitors the equipment's operating status in real time and enables remote control. Limiting devices prevent direct contact between the grinding rollers and liners, ensuring safe and stable operation.

Convenient Maintenance: The inspection cylinder can flip the grinding roller assembly outward, allowing for quick and easy maintenance of the rollers and liners, which minimizes downtime.

Environmentally Friendly and Clean: Vibration-damping technology and soundproofing materials are used to control vibration and noise. The system operates under negative pressure and is equipped with an efficient dust collection system, resulting in minimal dust emissions that comply with environmental standards.
