Mathematical Analysis of High Pressure Grinding Roller press Hard Alloy Pins and Roller Sleeve Wear Layer

How to form a long life wear layer between high pressure roller press tungsten Carbide Button and roller press steel body roller sleeve, depending on the following factors:

l  Wear-resistant layer surface area coverage is more than 75%, which is conducive to the formation of material deposition, to protect the high pressure roller press roller sleeve.

l  The height of the tungsten Carbide Pin stud exposed to the roller sleeve is related to the diameter of the Hard Alloy Stud and the diameter of the roller sleeve.

l  The height of the carbide pin exposed to the roll sleeve is associated with the size of the crushed material in the crusher under the working condition.

The hard alloy stud roll surface is the latest roll surface technology developed to meet the high hardness and high wear material. The stud roll surface adopts the technology of inserting studs on the mother roll cover. The studs are made of tungsten - cobalt hard alloy. Sintered, the hardness is up to HRC67 or above, it overcomes the shortcomings of the original surfacing roll surface wear speed is too fast, especially suitable for roller grinding of cement raw materials, clinker and metal ore, its wear resistance and service life are greatly improved.
