摘 要
随着改革的深化和谷物和石油市场的全面开放,使用4 p,4核心和1炉渣工艺或4 p连续生产带有4至6台磨豆机的小型工厂。 5芯和1渣过程。我国的县级工厂中有许多这样的工厂,因此讨论在这些工厂中共同生产特殊初级面粉和特殊次级面粉是重要的实践指南。本机采用10磨辊配置角度,进给性能好。进料流可以直接进入磨削区域,方便操作人员观察和调整进料情况。粉碎后的物料不会喷洒粉末,将其安装在下部研磨门上并拆除,更换研磨辊很容易。磨辊轴的大皮带轮和同步皮带轮均采用张紧连接,便于装卸。进纸辊离合器采用摩擦片式离合器,进纸辊的力来自慢速辊。该机器的第一步是用快速滚动驱动——电机,采用三角皮带传动,滚动节距调节机构采用单调的单轮离合器滚动。
近年来,特殊的两种粉末具有价格低廉和质量适中的优点。对磨床驱动力的半经验计算公式的进一步说明在设计和计算辊磨机主要部件的强度时,在确定磨床的几何参数,速度和其他工艺条件时,我们选择合适的径向工作载荷q等效摩擦系数快而慢,可以使用半经验公式更方便地完成。

Abstract
With the deepening of reform and the full opening of grain and oil markets, small factories with 4 to 6 bean mills are produced continuously using p,4 4 core and 1 slag process or 4 p. 5 core and 1 slag process. There are many such factories in the county factories in our country, so it is important to discuss the joint production of special primary flour and special secondary flour in these factories. This machine adopts 10 grinding roller configuration angle, feed performance is good. Feed flow can directly enter the grinding area, convenient for operators to observe and adjust the feed situation. The crushed material will not spray powder, install it on the lower grinding door and remove it, it is easy to replace the grinding roller. The large pulley and synchronous pulley of the roller shaft are tensioned and connected to facilitate loading and unloading. The paper roller clutch adopts friction disc clutch, and the force of the paper roller comes from the slow speed roller. the first step of the machine is to drive the —— motor with fast rolling, with a triangular belt drive, and the rolling pitch adjusting mechanism with a monotonous single wheel clutch rolling.
In recent years, the two special powders have the advantages of low price and moderate quality. Further explanation of the semi-empirical formula for calculating the driving force of grinding machines when designing and calculating the strength of the main components of the roller mill, when determining the geometric parameters, speeds and other technological conditions of the grinder, We choose the appropriate radial working load q the equivalent friction coefficient is fast and slow.
Keywords: flour; grinding machine; grinding roller; feeding roller; rolling distance adjusting mechanism
