To Increase the Utilization Rate of Existing Resources

Descripción

In order to reduce the energy consumption and reduce the size of the final crushing products as much as possible, the principle of more crushing and less grinding should be guaranteed and the workload of each stage crusher should be balanced distribution. Because the energy utilization rate of dry-grinding is only 2~3 percent, after years of scientific research and production practice, the domestic and overseas engineering technical personnel puts forward the pre-grinding technology with ‘less crushing and more grinding, replacing crushing by grinding’, which increases the production output, decreases the power consumption, and has a good effect on production-increasing and energy-saving.According to the discharging mode is not the same, and can be divided into lattice type cement mill and overflow type ball mill for cement two.

As we all know, cement mill is the material being broken, and then to smash the key equipment. It is widely used in cement, silicate products, new building materials, chemical fertilizer, non-ferrous metal processing and the glass ceramic production industry, various ores rotary dryer Ball mill Rotary dryer and other materials may be grinding of dry or wet grinding.Powder-grinding equipments maily include raymond pulverizer,micro powder mill,bucket elevator and belt conveyor,etc. Iron Ore beneficiation is a complex process, it aims to remove the unwanted impurity materials or gangues, improve the iron ore grade and refine the concentrate for final applications.

The so-called ‘pre-grinding’ technology is to make the particle size of material from the original size 20-25 mm to the final size 3-5mm and finish the crushing work in the crushing equipment, which improves the production output of the mill. Generally speaking, according to the product particle size, the crushing equipment with the product particle size of less than 3-5mm is called the fine crusher. Generally speaking, the mill production capacity is at the standard that the average particle size of materials is 25mm. Under the condition that the average particle size of materials is less than 25mm, the mill production capacity is calculated by the following empirical formula:
