摘  要
                                  
    粉碎機(jī)是將大尺寸的固體原料粉碎至要求尺寸的機(jī)械設(shè)備，粉碎機(jī)由粗碎、細(xì)碎，風(fēng)力輸送等裝置組成，以高速撞擊的形式達(dá)到粉碎機(jī)之目的。粉碎機(jī)械是應(yīng)用機(jī)械力對(duì)固體物料進(jìn)行粉碎作業(yè),使之變?yōu)樾�塊、細(xì)粒或粉末的機(jī)械，粉碎機(jī)械是破碎機(jī)械和粉磨機(jī)械的總稱。
 本課題設(shè)計(jì)的是為一種小型的，經(jīng)濟(jì)型的粉碎機(jī)——錘片式粉碎機(jī)。該機(jī)結(jié)構(gòu)簡(jiǎn)單，使用方便，主要運(yùn)用于糧食加工行業(yè)和食品加工行業(yè)，比較適合小型作業(yè)的用戶，本課題主要通過對(duì)粉碎機(jī)進(jìn)行分析、設(shè)計(jì)和計(jì)算，達(dá)到了解、掌握粉碎機(jī)相關(guān)零部件的設(shè)計(jì)計(jì)算內(nèi)容，受力狀況，受力特點(diǎn)，計(jì)算和分析方法。完成中心軸、軸承等相關(guān)零部件的設(shè)計(jì)說明書，從而深入了解和掌握如何降低能耗，提高其工作穩(wěn)定性的途徑、方法和技術(shù)。

 The Design Of Grinder
 Abstract

   The mill is the large size of the solid material crushed to the requested size of machinery and equipment. It is composed of primary crushing, fine, wind transport and other devices by high-speed crash to achieve the aim. Crushing machine is applied mechanical force to smash the operation of solid materials, making it a small, fine or powder machinery. The grinder is the general of broken machinery and mill machinery.
 This topic is designed as a small, economical grinder - hammer mill. It has many advantages: simple structure, easy to use, mainly used in food processing industry and food processing industries, more suitable for users of small operations. This issue mainly through the mill carried out the analysis, design, and calculation, to understand and grasp the relevant parts of the design and calculation of mill contents, mechanical condition, mechanical characteristics, calculation and analysis，complete of the central axis, the bearings and other related parts of the design specification. To understand and learn how to reduce energy consumption, improve the stability of its work means, methods and techniques.
