Embodiment Construction

[0024] figure 1 An embodiment of a metal pipe 1 for transporting material in a mineral processing plant is shown according to the first aspect of the invention. The metal tube 1 is hollow and cylindrical. The metal pipe 1 is made of high-strength steel and has a rubber coating 3 on its inner peripheral surface 2 . The rubber coating 3 provides good wear resistance when transporting abrasive materials. The metal tube 1 has a first end 4 and a second end 5 . The outer peripheral surfaces 7 of the first end 4 and the second end 5 of the metal pipe 1 are coated with an elastomeric coating 6 . The elastomeric coating 6 consists of rubber and is vulcanized onto the peripheral surface 7 . The preferred hardness of the rubber is preferably about 70° Shore A. However, the elastomeric coating 6 may naturally be any other elastomeric material with the same or different suitable hardness. Also, the metal pipe 1 may be made of other materials than high strength steel which are more s...

Abstract

The invention relates to a metal pipe (1) for transporting material in mineral processing plants. The metal pipe (1) has a first and a second end portion(4, 5). The metal pipe (1) is characterised in that an outer 5 circumferential surface (7) of the first end portion (4) is coated with an elastomeric coating (6).The invention also relates to a coupling device for coupling a first and a second transporting means, and a system for transporting material in mineral processing plants.

Description

technical field [0001] This invention relates to metal pipes for transporting materials in mineral processing plants. The invention also relates to a coupling device for coupling a first and a second means of transport, and a system for transporting material in a mineral processing plant. Background technique [0002] When crushing or pulverizing material in a mineral processing plant, several different methods can be used. During the crushing process, highly abrasive materials are transported throughout the processing plant. Highly abrasive materials are traditionally mixed with water and transported by means of transport consisting of rubber tubes with rubber-coated metal tubes on the inside. Rubber provides superior abrasion resistance when dealing with this abrasive material. Generally, rubber tubes are used in curved portions of transport routes, and metal tubes are used in straight portions of transport routes. [0003] The present invention relates to an improved ...
