Four Measures to Prolong the Service Life of Dust Catcher

The dust catcher is an important part of the drying machine which has the disadvantages of large volume of exhaust air, high concentrations of dust, high moisture content, high discharging point and wide range of pollution, bringing the difficulty for the dust removal technology. The exhaust gas of the dryer is related with the process conditions of individual enterprise such as the large production change, frequent downtime and large fluctuation range. Furthermore, if the coal is used as the drying heat sources, the sulfur oxides in the emission have corrosive effect on metal structure, which brings some difficulties for the selection of the dust catcher . The following are four measures to prolong the service life of the dust catcher of the dryers.
1. The material of the dust removal equipment should choose the alloy whose aluminum content is not less than 95%, which can greatly reduce corrosion.
2. The heat insulation of the dust removal system should be guaranteed. The entry of the cold air blast is one of the important reasons that cause the corrosion of dust removal equipment. As long as the heat insulation work is carried out well, the corrosion would be greatly reduced.
3. It can adopt the secondary dust removal program. The so-called secondary dust removal is to use the cyclone dust catcher with high wear resistance for primary dust removing and then to use the second dust remover for the final dust removing.
4. The operation of the drying equipment and dust collector should be standardized. The standardized operating procedure of the machinery is the necessary step, which can minimize corrosion.

The Reasons for the Low Flour Yield of Grinding Mill

The grinder mill market is continuously expanding and has wide range of its customers base. It always occupies an important position in the field of coal preparation and slag processing fields. The grinding mill is mainly used for the processing and production of the calcite powder, lime powder, sierozem, long powder, gypsum powder, talcum powder and other raw materials. Our company has the comprehensive study and understanding of the grinder mill based on the production and sales experience of mill equipment for many years and has accumulated research and experience in handling a large number of problems mill equipment and summed up a lot of ways accordingly. The following is the reason for the low flour yield of the grinding mill.

1, the material. The grinding miller adopts the dry milling, if the moisture content of materials is excessive or the materials contain other impurities, it will cause the internal bond, which not only has a greater impact on the production of the mill, but also cause the damage of the accessories of the mill if the time is too long. If it can not be ruled out in a timely manner, the consequences could be very serious.
2, feeding particle size. Generally, the customers have high requirements for the discharging particle size of the mill, because that the fineness of the finished product directly affects their economic benefits. However, in fact, the feeding particle size is also very important. If the feeding particle size is too large or too small, it will cause a great impact on the production and running of the grinding miller. If the feeding particle size is too large, the material is easy to cause the blockage on the feeding end, which is not easy to achieve the grinding crushing between the rollers and the grinding ring; if the feeding particle size is too small, it is not easy to form the material cushion in the grinding chamber and the direct collision of the roller and grinding ring will not only generate a lot of noise, but also make the mill generate large vibration, which is very unfavorable to the operation of the machine.

Disk Grain Making Machine/Disk Granulator

Performance features
The disk granulator produced by our company adopts the overall arc structure of the disk angle and granulation rate can be up to 93%. Granulating disc has three discharge ports, which makes it easy to conduct the intermittent production operations, greatly reducing the labor intensity and improving the labor efficiency. The flexible transmission of the reducer and motor helps the smooth start, the mitigation of the impact and the increase of the equipment service life. At the bottom of the granulation disk, it is strengthened by multiple radiation steel plates to make it durable without deformation. There is no need of anchor bolts to fix it due to the thicker, heavier, sturdy base design. The main gear adopts the high-frequency quenching, prolonging its service life. In the granulation disk, it is lined with the fiber reinforced plastics, which is anti-corrosion and durable. The surface is featured with the advantages of uniform granulation, high granulation rate, smooth operation and long service life and other advantages.

Working principle
The raw material powder is wetted evenly by the atomized water evenly in the biaxial mixer, forming the ball nuclear with uniform particle size, which will be sent into the disk for the next procedure. The moisture of the materials should be controlled at 12 ~ 14%. The water is mostly added in the biaxial mixer and only a small amount of water should be added in the disk. As for the dry powder granulation, an appropriate amount of water should be sprayed into the granulation disk. The raw material ball nuclear will do the parabolic motion under the role of centrifugal force, friction and gravity after entering the granulation disk. Due to the adhesion and plasticity of the material, the ball nuclear bonds with each other and gradually becomes large in the course of motion. In the continuous rolling process, the water in the raw material ball nuclear will be constantly discharged out of the surface. Due to the adhesion of the material and the natural evaporation of the liquid film on the surface, the pellet has certain strength so that they will be discharged out from the disk grain making machine with the rotation of the inclined disk.
