concrete mixer Description

Since the fall mixer has a long history, as early as in the 20th century, from the concrete batching plant Machine-driven concrete mixer drum cartridge has begun to emerge. 50 years later,  Reversal discharging the concrete mixing machine and tipping style double cone blender and stir split barrel Mixing machines have come out and be developed. Self-loading concrete mixers mix Cylinder wall of the mixing blades arranged radially. Work, mixing drum about its water Horizontal axis rotation, adding mix barrel materials, is raised to a certain height blade Degrees, by the weight of the whereabouts of this cycle of movement, to achieve uniform mixing Mixed results. Self-loading concrete mixer simple structure, generally stir Mixed plastic concrete based.
Compulsory mixer from the early 1950s after the rise, has been rapidly Development and promotion. First there is the disc vertical shaft forced concrete mix Mixing machine. This mixer is divided into two kinds of turboprop and planets. 19th Century 70 Years later, with the application of lightweight aggregate, there has been a circular groove horizontal shaft forced mixing Mixing machine, which in turn sub-single-shaft and twin-shaft two kinds of lying, both self-loading and strong Made in two mixing characteristics. The linear velocity of the stirring blade is small, good wear resistance And low energy consumption, faster development. Forced concrete mixer mix turn the barrel Stirring blades mounted on shaft arm, add mixed material tube, the mixing leaf Sheet under strong agitation to form a cross stream. Cement silo method than Since the fall agitation effect strongly, mainly suitable for mixing dry concrete.
Continuous concrete mixer equipped with a spiral mixing blades, a variety of materials After continuous mixing ratio respectively weighed into the mixer, mixing well mixed Concrete continuously outward from the discharge end of the unloading. The mixing time is short mixer, The production rate, the development of attention. With concrete materials and construction technology development, and have appeared in many New structure of concrete mixers, such as steam heated mixer, supercritical Speed mixer, sonic mixer, a wobble plate type stirring blade without mixing  Machines and secondary mixing of concrete mixer and so on.
