There are two kinds of forced mixers: single horizontal shaft mixer and double horizontal shaft mixer. Their components and working principles are different. This paper introduces the working principle and characteristics of single horizontal shaft mixer.
First of all, the single horizontal shaft mixer is composed of frame, mixing device, transmission system, limit device and electrical control system. 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.
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.
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.
