摘要

通过为期几天的对国内外相关产品的了解，对其产品技术和机构先进性深入研究，结合自身条件和设计要求对磨粉机做出相应改动。

本机的结构简单、紧凑，实用性强，装、拆、检修方便，而且各个结构的尺寸都比较小。本机磨辊内平置，其喂料性能好；喂料流可直接进入粉碎区，并便于操作人员观察和调整喂料情况；粉碎后的物料对下磨门无喷粉情况，拆换磨辊方便。磨辊轴上的大皮带轮和同步带轮均采用弹性换联结，装拆方便。磨辊传动采用源弧形双面同步齿形带，而且把改向轮和张紧轮合为一个改向张紧轮，其结构简单、紧凑，赶得上国际先进水平。喂料辊离合器采用了摩擦片离合器（气动离合），料门的启闭采用伺服电机，喂料辊的动力来源于慢辊，这些都达到了国际先进水平。本机的第一级传动——电机到大皮带轮，采用窄形（SPA）三角带，；两个喂料辊间采用单面同步齿形带，轧距调节机构采用止推块，启动离合闸，而且保安装置就是利用本气缸，这些在国内是不常见的，所以说本机是一台先进的磨粉机。

Abstract

Through a period of several days of related products for domestic and international understanding. Technology and institutions for their products-depth study of nature, combined with their own conditions and design requirements of the milling machine to make the appropriate changes.

The machine structure is simple, compact, practical, equipment, demolition, maintenance convenience, and the size of each structure are relatively small. Roller inside the machine level home, the feeding performance; feed flow directly into the crush zone, and to facilitate the operator to observe the situation and adjust the feed; the materials after crushing mill next door without powder, the grindingconvenient roll. Axis of the large roller and timing belt pulley wheel are used for connection flexibility, convenience Assembly and Disassembly. Roller arc source using double-sided drive belt synchronization, and tension to divert round and round together for a round of divert tension, and its structure is simple, compact, catch up with international advanced level.

Feed roller clutch friction plate clutch uses (pneumatic clutch), material hoist doors using a servo motor, the power feed from the slow roll-roll, which reached the international advanced level. The local transmission of the first level - the largest motor pulley, using a narrow-shaped (SPA) Triangle,; the two feed rollers between the use of single-sided tooth synchronous belt, rolling away from the regulating agencies the use of thrust blocks, start from the closing , and the security device is the use of the cylinder, which is not common in China, so to say that this machine is an advanced milling machine.

Keywords flour mill；grinder roll；Clutch disc facing；feed roller
