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.

磨面機是在現有錐式磨磨頭的定磨頭和動磨頭出粉端的磨齒槽端部，各增加了一圈厚度與磨齒高度相同的堵頭。這樣，在磨齒間得不到充分破碎的粉粒無法從堵頭通過，從堵頭通過的粉粒又得到了進一步研磨，從而可提高小麥的精粉率、精粉質量和磨面效率，而且磨齒不易損壞。

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.

磨面機包括機座和安裝在機座上的動力軸以及與動力軸連接的、與帶有進料口的磨坊配合的磨錐，其技術方案為：沿動力軸的軸向設置有磨坊與磨錐的間隙調節機構。可根據待加工糧食顆粒大小(如玉米、小麥等)和對加工后糧食粗細的不同要求進行調節，以滿足不同用戶的要求。

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.

離心卸料器殼體上方一側設有進料管，離心卸料器殼體上方設有出風管，離心卸料器殼體一側設有排雜口，排雜口上設有篩網，篩網外側設有蓋板，排雜口下方設有轉換閥連接排雜管，能夠將隨糧食顆粒一起下落的灰塵雜物去除，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.
