There are two kinds of forced mixers: single horizontal shaft mixer and double horizontal shaft mixer. Their components and working principles are different. Altay self loading mixer introduces the working principle and characteristics of single horizontal shaft mixer.

，单卧轴搅拌机的构成：由机架、搅拌装置、传动系统、限位装置及电器控制系统所组成。

First of all, the single horizontal shaft mixer is composed of frame, mixing device, transmission system, limit device and electrical control system.

机架是整个设备的支撑部分，由槽钢焊接而成，搅拌装置由搅拌筒，搅拌轴，搅拌铲片所组成，搅拌铲片固定在搅拌臂上，并且与搅拌轴组成一体形成两组螺旋方向相反，但导程及螺旋升角相同的螺旋带状搅拌铲，搅拌铲与搅拌筒内臂间隙可微量调整。自上料搅拌车，传动机构是由减速机和联轴器组成，筒体限位装置由锁定销及定位孔所组成，电器控制系统具有起动、点动、停止、定时的功能。

The frame is the supporting part of the whole equipment, which is welded by channel steel. The mixing device is composed of mixing drum, mixing shaft and mixing shovel. The mixing shovel is fixed on the mixing arm and integrated with the mixing shaft to form two groups of spiral belt mixing shovel with opposite spiral direction but same lead and spiral angle. The gap between the mixing shovel and the inner arm of the mixing drum can be slightly adjusted. The drive mechanism of self feeding mixer is composed of reducer and coupling. The cylinder limiting device is composed of locking pin and positioning hole. The electrical control system has the functions of starting, inching, stopping and timing.

其次，单卧轴搅拌机的工作原理：减速电动机通过连轴器使搅拌轴沿一个方向旋转，搅拌轴上的正反两组铲片搅拌物料，由于螺旋升角的作用，铲片工作时使筒内的物料由一侧推向另一侧，又由另一侧推回原处的循环动作，使物料得到充分的搅拌，从而获得理想的搅拌效果。自上料搅拌车，卸料时须停机，打开锁定销，使筒体旋转一定角度，再限位，按点动按钮，实现拌和物排出筒外。

Secondly, the working principle of the single horizontal shaft mixer: the reduction motor makes the mixing shaft rotate in one direction through the shaft coupler, and the positive and negative shovels on the mixing shaft stir the materials. Due to the effect of the spiral angle, the shovels make the materials in the cylinder push from one side to the other side, and then push back from the other side, so that the materials are fully stirred, So as to obtain the ideal stirring effect. When the self loading mixer is discharging, it must stop, open the locking pin, make the cylinder rotate at a certain angle, then limit, and press the inching button to discharge the mixture out of the cylinder.

单卧轴搅拌机的用途及特点：适用于建筑科研单位和建筑公司及混凝土构件单位试验室，可搅拌普通混凝土，轻质混凝土及干硬性混凝土，也可应用到其它行业试验室对不同物料进行搅拌。自上料搅拌车本机操作方便，搅拌效率高，残余量小，清洗方便，是较为理想的试验室用混凝土搅拌设备。

Application and characteristics of single horizontal shaft mixer: it is suitable for laboratories of construction research units, construction companies and concrete component units. It can mix ordinary concrete, light concrete and dry concrete. It can also be used in laboratories of other industries to mix different materials. The self loading mixer has the advantages of convenient operation, high mixing efficiency, small residue and convenient cleaning. It is an ideal concrete mixing equipment for laboratory.
