Embodiment Construction

[0022] The following non-limiting examples illustrate the invention.

[0023] refer to Figures 1 to 5 Shown: an anti-wear densely packed armor roll surface, including a roll surface substrate 1, and an anti-wear armor layer 2 fixed on the roll surface substrate 1, the anti-wear armor layer 2 is composed of several closely arranged and fixed on the The armor unit 4 on the roller surface substrate 1 is formed, the armor unit 4 is a cone as a whole, and is made of an upper regular hexagonal prism 41 and a lower cone 42, and the armor unit 4 is provided with a bolt hole 43 along its central axis. Alternatively, as shown in this embodiment, the armor unit 4 is made of a material with much higher wear resistance than the roll surface base 1, the roll surface base 1 is made of high-strength steel, and the armor unit 4 is made of hard alloy. The size of a single armor unit 4 is determined by the roll size. The armor unit 4 is connected and installed on the roll surface base 1 by bo...

Abstract

The invention discloses an antiwear close-packed armor roll surface, and belongs to the field of roller presses (high-pressure roller mills). The antiwear close-packed armor roll surface comprises a roll surface base body and an antiwear armor layer, wherein the antiwear armor layer is fixed on the roll surface base body and is composed of a plurality of armor units which are tightly arranged and are fixed on the roll surface base body through bolts; and each overall armor unit is a cone body and is composed of a regular hexagonal prism body on the upper part and a cone body on the lower part. The roll surface base body disclosed by the invention is not easy to wear; the demands on the materials and the processing equipments of the roll surface base body are reduced; the fabrication cost is reduced; the roll surface disclosed by the invention is good in wear resistance and long in service life; and a surface wear-resisting layer is not easy to wear, can be used at relatively high temperature and is easy to assemble and disassemble.

Description

technical field [0001] The invention belongs to the field of roller presses (high-pressure roller mills), and in particular relates to a wear-resistant roller surface of a roller press used in roller press grinding equipment in industries such as building materials, cement, metallurgy, mining, coal, and chemical industry. Background technique [0002] In building materials, cement, metallurgy, mining and other industries, roller presses (high-pressure roller mills) are widely used for material grinding, and the life of the roller surface directly affects the production cost. [0003] At present, the roller surface of the roller press has the following types: wear-resistant surfacing roller surface, chilled cast iron roller surface, composite casting roller surface and stud roller surface, and the stud roller surface has a relatively long service life. However, the studs used on the stud roll surface are cylindrical, and the stud holes (cylindrical) on the roll surface substr...
