High Quality Black Alumina Wholesale Price Canada

It is necessary to estimate the fluidity of the brown fused alumina powder and the friction characteristics of the solid surface when handling the powder and the equipment for storing, transporting and processing the powder in the process of design and production. For this reason, the following friction angles of the green silicon carbide powder are often needed to be determined.

When the shear sliding is caused along a certain surface inside the brown aluminum oxide powder layer, the reverse tangent (tg-1) of the ratio of the shear force acting on this surface to the vertical force mainly reflects the engagement between particles, the friction angle between the powder and the solid plane, the minimum angle of the powder sliding on the inclined plane, and the three and four angles are the black silicon carbide friction conditions between the powder and the solid plane.


When the white corundum powder drops from a certain height of small hole to the plane, the angle between the conical bus and the horizontal plane is formed by the accumulation of the powder It is necessary to reflect the cohesiveness between the particles. There are many methods to determine the above friction angle, aluminum oxide abrasive which are often different from the author, and the measured value is also slightly different. How to effectively solve the problem of red products?


The schematic diagram of the measurement method is shown in the figure. Due to the relationship between the materials , brown fused alumina price as an abrasive is very different from other products, because the alumina content in white corundum is relatively high, which can meet the application requirements of various occasions. However, in the application process of aluminum oxide grit abrasive, there will be adverse reactions.


For the design hopper, storage tank, sliding Groove, pipeline air transportation and other white alumina devices, wall friction angle are important data. First of all, we need to know the cause of the problem. After analysis, it is found that the red color of white corundum abrasive may be caused by the presence of iron in the binder of the aluminium oxide blasting grit production product; it may be due to the excessive contact with iron mechanical process during the processing.


Therefore, the existence of iron in black corundum products should be minimized. In order to achieve the best use effect, it is necessary to avoid the existence of air in the process of abrasive production, and pay attention to the control of abrasive particle size of white corundum, so as to avoid the occurrence of various adverse phenomena. This is the artificial corundum quality address of the unit volume of the powder in the state of natural accumulation.


When designing the device for handling the powder by volume, such as: the storage bin of pink corundum raw materials or binders; the transport device; the volume of the mixer; the storage bin or transport trolley of the molding materials; the hopper of the press system, the height of the mold; the constant volume feeding during the molding, etc., the accumulation density of the aluminum oxide blasting abrasive powder must be considered. In production, the first two conditions generally change less.


As for the molding material of silicon carbide abrasive tools, because it is composed of a variety of powder materials with different density, and there is a wetting agent added to it, its stacking density is related to the formula of the molding material, the type and number of sites of the wetting agent, more specifically, it is related to the type and size of abrasive, the type and aluminum oxide abrasive blasting grit density of the wetting agent, and the adding site of the wetting agent (i.e. the degree of dryness and wetness of the molding material).
