Embodiment Construction

[0017] Embodiments of the present invention are described in detail below.

[0018] The textured grinding roller is shown in Figure 1, including a roller body (1) and a shaft head (2). As shown in Figure 2, it can be seen that the left-handed and right-handed double-textured grinding rollers use high-temperature nozzles to perform close-range right-handed and left-handed two-way scanning processes on the circumferential surface of the relatively rotating grinding rollers to form surface contours. Microscopic roughness, roller body (1) The microscopic roughness of the surface profile should theoretically be a dense network of left-handed and right-handed traces. The mesh points can show the peaks and valleys of the profile microscopically, and the peaks are the mesh points, which feel rough to the touch, and the average height is expressed as 3.5-9.5 μm by the roughness value Ra. From the partial photo of the surface of the two-way textured grinding roller in Figure 3, it can ...

Abstract

The present invention relates to a frosted grinding roller and its production process. It is characterized by that said invention adopts grinding roller smooth roller, and utilizes high-temperature nozzle to make close right-rotary and left-rotary bidirectional or unidirectional scanning machining along roller body surface so as to produce contour micro roughness, and the mean height can be represented by roughness value Ra and can be 3.5-9.5 micrometer. Said frosted grinding roller has high surface hardness and can greatly raise working efficiency.

Description

Technical field [0001] The invention relates to a grinding roller of a mill for grain processing, grinding and milling, in particular to a grinding roller of a double-roll mill and a production process thereof. Background technique [0002] The double-roller mill is the main equipment of the milling machinery, and the grinding roller is the core component of the double-roller mill. A set of medium-sized or above flour mills usually uses multiple mills, that is, mills composed of multiple pairs of roller units. Wheat and other materials crushed by grinding rollers are classified by powder cleaning and sifting equipment to separate large, medium and small particles, which are sent to different mills for grinding. According to different particles, the mills are divided into There are four systems of leather, slag, heart and tail. The leather mill generally uses toothed rollers, which can break, peel, scrape, and grind the material multiple times; The particles are ground to r...
