Problems solved by technology

The industrial use of equipment at home and abroad shows that the wear of the substrate is much faster than that of the cemented carbide studs, which limits the life of the entire roll surface; High, so that the cost of the roll surface is also very high

Embodiment Construction

[0015] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0016] All features disclosed in this specification, or steps in all disclosed methods or processes, except for mutually exclusive characteristics and / or steps, can be combined in any way, unless otherwise stated, they can be used by other equivalent or similar Instead, each feature is intended to be replaced by alternative features, that is, each feature is only one embodiment of a series of equivalent or similar features unless stated otherwise.

[0017] Such as figure 2 , image 3 As shown, the cemented carbide stud roll surface of the present invention includes a roll surface 1 and a large stud 2, and the large stud 2 is arranged on the roll surface 1, and a small stud 3 is also arranged on the roll surface 1. The small stud 3 is arranged around the big stud 2 , and the outcrop height of the small stud 3 is lower than that of the big stud 2 ...

Abstract

The invention discloses a hard alloy stud roller surface. The hard alloy roller surface comprises a roller surface and big studs which are arranged on the roller surface; small studs are also arranged on the roller surface; the small studs surround the big studs, and the exposed height of the small studs is smaller than the exposed height of the big studs; the roller surface is made of high-intensity steel; and the large and small studs are made of hard alloy. In the hard alloy stud roller surface, clearance among the studs is reduced, materials can be well protected by a firmer self-generation material cushion and a roller substrate, the service life of the roller surface is prolonged, running efficiency of equipment is effectively improved, and manufacturing cost of the roller surface is reduced.

Description

technical field [0001] The invention relates to a stud roller surface, in particular to a cemented carbide stud roller surface used in roller presses in roller press grinding equipment in industries such as building materials, cement, metallurgical mines, coal, and chemical industry. Background technique [0002] The roller press is also called the high-pressure roller mill. Under the action of the hydraulic system, the two oppositely rotating extrusion rollers of the roller press mill generate a huge extrusion force to crush the material. The life of the extrusion roller surface is related to the operation rate of the equipment and maintenance costs. When the roller press rolls hard-to-grind materials, such as steel slag, iron ore, quartz ore, etc., the roller surface is usually inlaid with cemented carbide studs to ensure the wear resistance of the roller surface. Carbide studs are inlaid on the roller surface such as figure 1 As shown, the method adopted is to displace ...
