Should check the geared motor, barrel, bearing, and so has not been damaged in transit mortar mixer, whether or loose fasteners, if loose should be tightened, the support foundation for the smooth concrete floor after unpacking installation considerations machine, blender handling the application of the rope tied to the frame, not the agitator shaft in series, mixer below the base with casters, can be any movement. The main features of the machine easy to operate, high mixing efficiency, small residual amount, easy to clean, is an ideal laboratory use concrete mixing equipment. Compulsory mixer from the early 1950s after the rise has been rapid development and promotion. First there is the disc vertical shaft forced concrete mixer. This mixer is divided into two kinds of turboprop and planets. After the 1870s, with the application of lightweight aggregate, there has been a circular groove horizontal axis compulsory mixer, which in turn sub-single-shaft and twin-shaft two horizontal drum mixer, both from falling and forced two stirring characteristics. Its stirring blade linear velocity is small, good wear resistance and low energy consumption forced concrete mixer, faster development. Equipped with a stir on compulsory concrete mixer mix arm blade shaft barrel, adding mix material barrel, stirring blade strong agitation to form a cross stream. This mixing method than intense action since the fall mixer mixing methods, mainly adapted to mix dry hard concrete.
