Abstract

FIELD: technique for material grinding, applicable in food, chemical and other industries. SUBSTANCE: grinding device has horizontal cylindrical body accommodating working member and systems of material loading and unloading. Working member is made in form of toroidal member installed for reciprocation by means of the systems for supply and discharge under pressure of working medium. The systems are located on the body on both sides of toroidal member separating body into two hollows of which one is communicated with loading system, and the other, with system of discharge of ground material. Toroidal member has teeth. EFFECT: higher efficiency. 2 cl, 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]
The disadvantage of the installation is the design complexity.

A device for grinding, adopted as a prototype and consisting of a body, a working body, made in the form of an elastic balloon with a core [2]
The disadvantage of the prototype: the complexity of the design.

 An object of the invention is to simplify the design.

 To do this, in the grinding device containing a horizontal cylindrical body with a working body located inside it and a material loading and unloading system, the working body is made in the form of a toroidal element mounted with the possibility of reciprocating movement using the supply and removal systems of the working agent located on the housing on both sides of the toroidal element dividing the housing into two cavities, one of which is in communication with the initial loading system, and the other with the unloading system and grinded material. The toroidal element is provided with teeth.

 The drawing shows the proposed device, General view.

 The grinding device consists of a horizontal cylindrical body 1, inside of which a toroidal element 2 is installed, equipped with teeth 3. A toroidal element 2 divides the housing 1 into cavities 4 and 5, each of which communicates with pressure systems 6 and 7, respectively, for supplying and removing the working agent under pressure . The cavity 4 communicates with the feed material supply system 8, and the cavity 5 communicates with the crushed material removal system 9.

 A device for grinding works as follows.

 In the cavity 4, the feed system of the working agent 6 serves the source material. The working agent is fed alternately by systems 6 and 7, then into the cavity 4, then into the cavity 5. The toroidal element 2 is rolled back and forth inside the housing, grinding the source material. Grinding is carried out by abrasion by the teeth of the source material between the toroidal element 2 and the walls of the housing 1 or in the central part of the toroidal element 2. The crushed material is extruded by the toroidal element 2 into the system 9 for removing the crushed material.

 The grinding device is distinguished by its simplicity of construction and due to this relatively low cost. The grinding device has a sealed housing that eliminates dust separation, spillage of crushed material.
