Abstract

FIELD: technique of material grinding; applicable in food chemical and other industries. SUBSTANCE: grinding device has horizontal cylindrical body with working member and systems for loading of initial material and unloading of ground material. Body is provided at its end faces with system of working medium supply and discharge. Working member is made in form of two cylindrical ring- shaped members fitted on rod having thick section in central part. Systems of loading of initial material and discharge of ground material are communicated with hollow between cylindrical ring-shaped members. EFFECT: higher efficiency. 1 dwg

Description

 The invention relates to techniques for grinding materials and can be used in food, chemical and other industries.

Known crushing and screening plant containing a drive, an unbalanced shaft, a drum, a roller table [1]
Disadvantages: design complexity, high material consumption.

Known rod mill containing a drum, grooved elements, folding pockets [2]
Disadvantage: design complexity.

 The purpose of the invention is to simplify the design.

 To do this, in a grinding device containing a horizontal cylindrical body with a working body and systems for loading the initial and unloading of crushed material, the body from the ends is equipped with supply and removal systems of the working agent, and the working body is made in the form of two toroidal elements worn on a rod having a thickening in the central part, moreover, the systems of initial and unloading of crushed material are communicated with a cavity between toroidal elements.

 Comparative analysis with the prototype shows that the inventive device is characterized in that it is equipped with a rod with a thickening, and the rod is threaded into the core of toroidal elements.

 The drawing shows a General view of the proposed device.

 The grinding device consists of a horizontal body 1 with toroidal elements 2 and 3, through the central part of which the rod 4 passes. The rod 4 in its central part has a bulge 5, and there is an annular gap between the bulge 5 and the inner wall of the housing 1. Case 1 communicates with systems 6 and 7 of the supply and removal of the working agent. The cavity 8 communicates with the feed supply system 9 and the crushed material collection system 10.

 A device for grinding works as follows.

 System 9 serves the source material, and system 7 into the housing 1 working agent. Toroidal elements 2 and 3, and with them the rod 4 are moved to the right. The thickening 5 and the toroidal element 2 abrade the starting material. The crushed material is removed by the crushed material collection system 10. As soon as the rod 4 is in the leftmost position, the working agent supply system 6 is turned on under pressure, and the working agent removal system 7 is switched to the removal of the working agent from the housing 1. The rod 4, toroidal elements 2 and 3 are moved to the left. The initial product is then crushed by a thickening 5 and a toroidal element 3. The rod 4 occupies the leftmost position and the cycle repeats.

 The grinding device has a simple design, which reduces repair costs, improves performance.
