Flat grinding joint of fine grinding mill

Abstract

The invention discloses a flat grinding joint of a fine grinding mill. The flat grinding joint comprises a metal block and a threaded hole and is characterized in that the metal block (1) is cylindrical, and an external round face (2) and an internal threaded hole (3) are formed in the metal block (1); the diameter of the external round face (2) is 54+0.011mm to 54+0.030mm; the threaded hole (3) is downwards drilled in the center of the upper surface of the metal block (1), is a through hole and is drilled through from the upper surface of the metal block (1) to the lower surface of the metal block (1); the radius of the threaded hole (3) is 16mm, and the thread pitch is 1mm; the external round face (2) and the internal threaded hole (3) are concentric circles; the height of the metal block (1) from top to bottom is 28mm; the external peripheral side of the upper surface of the metal block (1) is turned to form a circle of 45-degree chamfers (5), and the chamfering distance is 1 mm; and the external peripheral side of the lower surface of the metal block (1) is turned to form a circle of 45-degree chamfers (4), and the chamfering distance is 1 mm.

Description

technical field [0001] The invention relates to a flat grinding joint of a fine pulverizer, in particular to a flat grinding joint of a fine pulverizer for recycling and processing old rubber products such as waste automobile tires and bicycle tires. Background technique [0002] Usually, due to incorrect design, unreasonable structure, wrong size, improper installation, etc. The fineness of the rubber can not meet the requirements, the thickness is uneven, the product quality is poor, not up to the grade, and the use value is low. Therefore, it is necessary to finely design, invent and innovate this ordinary pulverizer to form a fine pulverizer. Good, high-quality products, high utilization rate; and the flat grinding joint of the fine pulverizer is one of the important parts, the design is correct and the structure is reasonable, which can make the fine pulverizer work normally, with good sealing performance, firm connection and consistent performance Good, so as to ensur...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome defects such as wrong design and unreasonable structure of ordinary pulverizers and their flat-ground joints, resulting in inadequate processing, poor product quality, and low recycling rate, the invention provides a flat-ground joint of a fine pulverizer, which is An important part of the fine pulverizer, the design is correct and the structure is reasonable, so that the fine pulverizer can run normally during work, the sealing is good, the connection is firm, and the matching performance is good, so as to ensure the fine pulverizer to work stably, the fine pulverization is in place, and the processing accuracy high, good recycling
