With the advancement of coal preparation equipment technology and the improvement of the requirements for coal, the requirements for the traditional pulverization production of coal crusher are also constantly updated, which are embodied in the following aspects:
1. Requirements for washing equipment
Different washing equipments have different particle size ranges, which must be crushed to meet the requirements of washing equipment. For example: Dense medium cyclone is a washing equipment with high separation efficiency, and has strong adaptability, easy to automate production, and is widely used. However, if the particle size of the washing product exceeds the limit, it is easy to cause the phenomenon of plugging, which makes it unable to play an efficient role. In order to solve this problem, the crushing operation of the coal pulverizer must strictly ensure the feeding particle size.
2. The market needs coal crusher
Coal users have very strict requirements on product particle size. Different users have different particle size requirements, and this requirement is constantly changing with the market. It directly affects the economic benefits of coal enterprises. At the same time, the prices of products with different granularity specifications are different in different periods. In order to obtain maximum profits, enterprises must also rely on effective crushing operations.
3. The need for energy saving and consumption reduction
At present, in a concentrator, the production cost of crushing and grinding operations accounts for more than 40% of the total beneficiation cost, and the investment cost of crushing and grinding equipment accounts for about 60% of the total investment in the concentrator. Although the production cost and capital investment of the crushing operation in the coal preparation plant account for a lower proportion than that of the coal preparation plant, the impact of the production cost and capital investment of the raw coal preparation system on the technical and economic indicators of the coal preparation plant cannot be ignored. Therefore, it is of great significance to improve the crushing productivity and reduce the crushing power consumption.
4. Reduce over-crushing in crushing process
Excessive crushing in the crushing process of the coal crusher not only causes waste of resources and affects the economic benefits of coal enterprises, but also increases the moisture content of pulverized coal after selection, increases the pressure of the coal slime water system, and reduces the actual yield of clean coal by gravity separation. With the improvement of environmental protection requirements and the increase of pulverized coal treatment costs, minimizing pulverized coal output has become the key to crushing operations.
5. The need for deep coal processing and clean coal
In the process of coal washing, in order to maximize the dissociation of gangue and coal monomer, increase the specific surface area of raw materials, improve coal quality (reduce ash content, increase calorific value), and remove harmful substances such as sulfur and phosphorus in coal. In order to reduce the pollution of coal to the atmosphere when it is burned, it is necessary to carry out effective pulverization of coal.
