Vertical Mill for Limestone Grinding: Efficient and Eco-Friendly Processing Solution

Description

Limestone vertical mill is an efficient equipment specifically used for grinding limestone. The following is its related introduction:

Working principle
-Grinding principle: Limestone enters from the feed inlet and falls onto the rotating grinding disc. Under the action of centrifugal force, the material is pushed towards the edge of the grinding disc. The grinding roller is located between the grinding disc and the material, relying on its own gravity and external pressure to compact and grind the material, crushing limestone into fine powder.
-* * Powder selection principle * *: High temperature exhaust gas from the kiln tail or hot blast stove enters the mill through the nozzle ring, forming vortex wind to preheat and dry the material. The ground material is suspended by the exhaust fan to meet a certain fineness requirement and enters the powder selection machine. Some particles, due to collision with guide vanes or other reasons, are re ground by the heavy hammer valve. Qualified materials are collected by the cyclone tube as finished products.

###Application advantages
-Efficient and energy-saving: It integrates crushing, grinding, drying, powder selection, and conveying, with a simple process flow and high grinding efficiency. Compared with traditional grinding equipment, it can significantly reduce power consumption, effectively improve production efficiency, and reduce production costs.
-Good product quality: The special grinding roller and disc structure design ensures uniform particle size distribution, good fluidity, and high activity of the finished product, which can meet the strict requirements of different industries for the quality of limestone powder.
-Strong adaptability: It can use hot air transportation to dry materials with a moisture content of up to 15%, and has good adaptability to limestone raw materials with different humidity. It can also handle limestone with different hardness.
-Excellent environmental performance: The system is sealed as a whole, operates under full negative pressure, has low vibration and noise, and no dust overflow, which can effectively reduce environmental pollution and meet environmental requirements.
-Convenient maintenance: The grinding roller adopts forced thin oil lubrication and is equipped with a hydraulic flipping device. During maintenance, the grinding roller can be flipped out of the machine by the hydraulic device without disassembly, which is convenient and fast, can reduce maintenance costs, and improve equipment utilization.

###Application Fields
-* * Cement industry * *: Limestone is one of the main raw materials for producing cement. Limestone vertical mills can grind limestone to the appropriate fineness and use it in raw material preparation and other processes in cement production, improving the quality and output of cement.
-Building materials industry: Used for producing limestone powder as an additive in building materials, such as adding limestone powder to concrete, bricks and other materials, which can improve material performance, enhance strength and durability.
-The chemical industry provides raw materials for the production of chemical products, such as calcium carbonate, calcium hydroxide, and other chemical products widely used in industries such as plastics, rubber, coatings, and papermaking.
-Power plant desulfurization: After grinding limestone powder into fine powder, it is used for flue gas desulfurization in power plants. By reacting with sulfur dioxide, the emission of sulfur dioxide is reduced, achieving environmental protection goals.
