Stone flour mill, also known as flour mill, is composed of four systems: power, feeding, grinding and separation; The power system consists of motor, pulley, V-belt, main shaft pulley and main shaft; The feeding system consists of hopper and feeding pipe; The grinding system is composed of grinding body and supporting legs; The separation system consists of a brush mounted on the spindle, a spherical roller bottom with a compass net, a compression screw and a roller frame mounted on the bottom of the grinding body.

磨面机是在现有锥式磨磨头的定磨头和动磨头出粉端的磨齿槽端部，各增加了一圈厚度与磨齿高度相同的堵头。这样，在磨齿间得不到充分破碎的粉粒无法从堵头通过，从堵头通过的粉粒又得到了进一步研磨，从而可提高小麦的精粉率、精粉质量和磨面效率，而且磨齿不易损坏。

The grinding machine adds a circle of plug with the same thickness as the grinding tooth height at the grinding tooth groove end of the fixed grinding head and the moving grinding head of the existing cone grinding head. In this way, the powder particles that are not fully broken between the grinding teeth can not pass through the plug, and the powder particles that pass through the plug are further ground, so as to improve the flour yield, flour quality and grinding efficiency of wheat, and the grinding teeth are not easy to be damaged.

磨面机包括机座和安装在机座上的动力轴以及与动力轴连接的、与带有进料口的磨坊配合的磨锥，其技术方案为：沿动力轴的轴向设置有磨坊与磨锥的间隙调节机构。可根据待加工粮食颗粒大小(如玉米、小麦等)和对加工后粮食粗细的不同要求进行调节，以满足不同用户的要求。

The grinding machine comprises a machine base, a power shaft mounted on the machine base and a grinding cone connected with the power shaft and matched with a mill with a feeding port. The technical scheme is that a gap adjusting mechanism between the mill and the grinding cone is arranged along the axial direction of the power shaft. It can be adjusted according to the grain size to be processed (such as corn, wheat, etc.) and the different requirements of grain thickness to meet the requirements of different users.

离心卸料器壳体上方一侧设有进料管，离心卸料器壳体上方设有出风管，离心卸料器壳体一侧设有排杂口，排杂口上设有筛网，筛网外侧设有盖板，排杂口下方设有转换阀连接排杂管，能够将随粮食颗粒一起下落的灰尘杂物去除，制造成本低，使用能量消耗低。

A feed pipe is arranged on the upper side of the shell of the centrifugal discharger, an air outlet is arranged on the upper side of the shell of the centrifugal discharger, a screen is arranged on one side of the shell of the centrifugal discharger, a cover plate is arranged on the outside of the screen, and a change-over valve is arranged below the screen to connect the discharge pipe, which can remove the dust and sundries falling with the grain particles, with low manufacturing cost and low energy consumption.
