Large Capacity Slag Coal Cement Pet Coke Limestone Grinding Vertical Mill

Description

Firstly, the application value of limestone
1. Applied to thermal power plants
In today's society where environmental protection calls are increasingly high, the limestone gypsum wet flue gas desulfurization process is widely adopted due to its mature technology, high desulfurization efficiency, abundant sources of absorbers, low prices, and the availability of by-products. It has become the most widely used method for flue gas desulfurization in coal-fired power plants. Limestone is the most commonly used desulfurizer among them, and the fineness and quality of limestone have an impact on desulfurization. The quality of limestone is determined by the CaO content. The higher the purity of limestone, the better the desulfurization efficiency. Therefore, efficient preparation of limestone has become the primary problem for efficient desulfurization in thermal power plants and coal-fired power plants, and easy response to PM2.5.

2. Applied to the glass industry
Limestone, quartz sand, soda ash and other materials can be used in glass production after high temperature melting.

3. Applied to the steelmaking industry
In the steel industry, quicklime can be used as a slag making material to filter out harmful substances such as sulfur and phosphorus, becoming a flux and gangue for ironmaking.

4. Can be used for manufacturing filler materials
The fired limestone can be widely used as a filler in many fields such as rubber, plastic, paper, cosmetics, toothpaste, etc.

5. Can be used to make soda ash
Limestone can be combined with materials such as salt and ammonia to produce soda ash through multiple reactions.

6. Application in the agricultural field
Firstly, quicklime can be prepared into pesticides such as Bordeaux liquid and lime sulfur mixture; Secondly, hydrated lime can change the acidity and alkalinity of the soil, improve the internal composition of the soil, and supplement the calcium in the soil; Finally, lime slurry can also be used to paint tree trunks, playing a protective role in trees.

7. Application in the construction field
Everyone is familiar with the application of limestone in the construction field. In the construction industry, limestone is the main raw material for manufacturing cement, which can be used to build the exterior walls and floors of houses.

2, Recommendations for efficient limestone preparation equipment
With the vigorous development of the mining and manufacturing industry, the grinding equipment and process for preparing limestone are becoming increasingly mature. As the core equipment for limestone powder production, a series of economic indicators such as limestone powder quality, grading efficiency, and production capacity have become the primary consideration for enterprises to enhance market competitiveness and create broader development prospects. Hefei Hengcheng has rich experience in the development of limestone grinding machine equipment, strong technical force, and a highly skilled after-sales team. It has provided excellent powder equipment for the limestone preparation field worldwide, becoming a highly praised and favored leading enterprise by customers.

Technical Data

Limestone Bond Index≤13kwh/t

Working principle

The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing water are dried in the Contact process with hot gas to meet the required product moisture.

Materials that can be processed by HVM vertical mill: ferrite, slag, slag, cement, diamond, iron ore, chrome ore, manganese ore, gold mine, copper mine, aluminum ore, lead zinc ore, tantalum niobium ore, polymetallic ore, nickel ore, bauxite, silicon carbide, titanium dioxide, talc, bentonite, calcite, kaolin, graphite, mica, wollastonite, feldspar, dolomite, pyrophyllite, quartz sand, fluorite, limestone, organic silicon, limestone Shale, volcanic ash, coal, etc.

Advantages
1. Adopting a vertical structure design, it occupies a small area and has strong completeness. Whether it is from rough processing of raw materials, transportation, pulverization, and packaging, it can form an independent production system.
2. The operation is more stable and reliable, as the company has improved its main shaft and plum blossom frame during the production of vertical grinding machines, making their structure more stable.
3. It has stronger practicality and handles a wide variety of materials, including various non-metallic minerals such as gypsum, limestone, granite, and bluestone, making it highly flexible.
4. Long service life. The main components of the equipment are all cast with selected materials, and the process is fine, ensuring the high operating efficiency and good wear resistance of the entire Raymond grinding machine equipment.
5. The electrical system adopted by the vertical grinding machine is centralized control, which can basically achieve unmanned operation, improve the working environment, and save more labor and management costs for users.
