Graphite powder soft, black gray; Greasy and can contaminate paper. The hardness is 1 ~ 2 and increases to 3 ~ 5 along the vertical direction with the increase of impurity. Specific gravity is 1.9 ~ 2.3.Under the condition of starvation, its melting point above 3000
Graphite powder soft, black gray; Greasy and can contaminate paper. The hardness is 1 ~ 2 and increases to 3 ~ 5 along the vertical direction with the increase of impurity. Specific gravity is 1.9 ~ 2.3.Under the condition of starvation, its melting point above 3000 ℃, is one of the most heat-resistant mineral. At room temperature, graphite powder has stable chemical properties and is insoluble in water, dilute acid, dilute alkali and organic solvents. Materials with high temperature conductivity, can do refractory materials, conductive materials, wear-resistant lubrication materials.
Working principle of graphite vibrating screen:
Graphite powder vibrating screen machine is a kind of high precision fine powder screening machinery, the principle of work is by the vertical motor as the excitation source, motor, the lower and upper ends of the installation of eccentric heavy hammer, the motor rotation into a horizontal, vertical, oblique three dimensional movement, and then transfer the movement to the screen surface. Adjust the phase Angle of upper and lower ends, can change the course of movement on the surface of the material in the screen, vibration due to its operation principle, many companies also known as the "three dimensional vibration screening filter", according to shape structure is part of the customers' call for circular screen, from the material point of standard sieve and normal vibration sieve, and material contact part of the standard of 304 stainless steel material, base for carbon steel material, the ordinary type of the brick for carbon steel material. Graphite powder vibration screen type is from a diameter of 400- phi 1800mm, graphite powder vibration screen price according to the material and diameter size, the number of layers of price.
Factors influencing screening yield of graphite powder vibrating screen:
Factors affecting the output of graphite powder shaker can be divided into four main aspects: material characteristics, equipment model, and installation factors.
1. Physical properties of screened materials include particle size composition, humidity, mud content and particle shape, etc. When the content of fine grain is large, the productivity of sieve is also large. When the humidity of the material is large, generally speaking, the screening efficiency will be reduced. However, the larger the size of the sieve hole, the smaller the influence of water, so for wet materials with large moisture content, in order to improve the screening process, generally can be used to increase the sieve hole, or wet screening. Materials with a high mud content (when the mud content is more than 8%) should be screened wet or washed in advance.
2. The larger the effective sieve area (i.e. the ratio of the sieve hole area to the entire sieve surface area), the higher the unit area productivity and screening efficiency of the sieve surface. The larger the size of the sieve hole, the higher the productivity per unit sieve surface and the higher the screening efficiency.
3. Influence of production conditions when the load of the sieve is large, the screening efficiency is low. To a large extent, the peace rate of circular vibrating screen depends on the size of the sieve hole and the total screening efficiency. The larger the sieve hole, the lower the screening efficiency, the higher the productivity. Feed uniformity is of great significance to the screening process. The inclination of the sieve should be suitable, which is generally determined by experiments. Then, the amplitude and vibration of the sieve, which is related to the structural properties of the sieve, in a certain range, increasing the vibration can improve the screening index.
It should be noted that there are many types of graphite vibrating screen separators produced by our company, and customers need to choose appropriate equipment according to their own needs. If you are not clear about the choice of model, we will have professionals to guide you in the selection, so as to remove the late trouble caused by improper selection.
