摘 要
隨著食品工業(yè)的發(fā)展，以及市場(chǎng)需求的變化，近年來我國的磨粉機(jī)層出不窮。專用的食品加工用的磨粉機(jī)從無到有、從少到多有了長(zhǎng)足的發(fā)展。現(xiàn)今市場(chǎng)上有專用加工一種農(nóng)作物的磨粉機(jī)，也有可加工干澡作物的磨粉機(jī)，也有加工濕潤(rùn)以后的磨粉機(jī)，也有干濕兩用的磨粉機(jī)。從大型到小型，名目繁多。磨粉機(jī)的工作原理也不一樣，有的是用刀片切削的方式進(jìn)行粉碎，也有的用磨盤進(jìn)行磨碎，也有的先用一機(jī)構(gòu)進(jìn)行“切碎”，再進(jìn)行磨粉。
經(jīng)過我的現(xiàn)場(chǎng)的了解和對(duì)市場(chǎng)上各種磨粉機(jī)的探究，市場(chǎng)上的磨粉機(jī)主要是大型商用磨粉機(jī)和超小型磨粉機(jī)，沒有一種是中型磨粉機(jī)。這對(duì)需要中小型磨粉機(jī)的用戶來說，沒有合適的產(chǎn)品供其選擇。在這里我針對(duì)這種情況，設(shè)計(jì)了一款中型磨粉機(jī)，非常適合小型加工廠的使用?？赡ザ喾N農(nóng)作物，如大米、麥子等，也可磨植物的根、徑、葉等。
我所設(shè)計(jì)的小型多功能干濕磨粉機(jī)主要是改變物料的物理尺寸，利用機(jī)械的方法克服固體物料內(nèi)部的凝聚力而將大尺寸的固體變?yōu)樾〕叽绲墓腆w的一種加工。加工的刀具形狀是圓盤狀的磨盤，利用兩個(gè)磨盤的轉(zhuǎn)動(dòng)將物料研磨用剪切粉。

Abstract
With the development of food industry, and the change of market demand in China in recent years, the mill emerge in endlessly. With the special food processing mill from scratch, from less than to a considerable development. Now on the market have special processing a crop of mill, crops are also can do a mill, the crops have processing after wet mill, also have dry wet amphibious of grinding machine. From large to small, numerous. The working principle of grinding machine is different also, with a blade cutting of crushing, and some were with micropipette grinding, also have a mechanism to chop, then grinding.
After my site to understand and to all the mill, the market main have large commercial grinding mill and small-sized mill, no one is medium mill. This small mill in need of users, not suitable products for its choice.For this kind of situation, design a medium mill, very suitable for small factories .To many crops, like rice, wheat, etc, also can grind the roots of the plant, leaf, etc. I have small multi-function wet grinding machine mainly if you change the size of materials, mechanical method overcomes the internal cohesiveness and solid materials will be large size of solid into small size of solid a processing. Machining tool of the disc mill is turning millstone, using two material abrasive shear powder.
Keywords: Grinding machine, disc, multi-function, dry and wet,crop
