The Steel Ball Auto-Sorting Machine from China North Industries Group Corporation Jilin Jiangbei Machinery Manufacturing Co., Ltd was Authorized by China
The hardness of the steel ball is one of the key technical indicators for the steel ball quality, and in the national standard GB/T308-2002 《Rolling Bearing & Steel Ball》,it is required that to extract no less than nine steel ball in each batch of products to test the hardness of the steel ball by making the crushing strength tests, and this method could not 100% to test the hardness; however, the hardness of the steel ball in some products' key components which produced by some enterprises often require 100% inspection, thus the traditional testing methods could not meet the products' performance requirements.
Therefore, this patented technology is a kind of steel ball hardness test method & auto-sorting machine which was designed by the technical personnel from Jilin Jiangbei Machinery Manufacturing Co., Ltd according to the collision theory in physics. And this technology has achieved the on-line auto-sorting operation, at the same time, it also has many advantages, such as, simple structure, high sorting rate, 100% sorting accuracy, low cost, etc., besides, the promoting application value is quite high.
