Concrete mixer is the core equipment of concrete mixing station, in addition to the dry type plant has not the mixing machine, the concrete is mixed in the concrete transport tank truck; the mixing of concrete in other mixing stations is carried out in the mixing machine. There are many types of mixing machines, and several common types are introduced below.
Drum type and batch type
Concrete mixers can be divided into two categories by mixing principle: batch type and self-falling type. The tank body of the batch mixer does not move, and is rotated by the mixing shaft. The mixing blade is driven by the mixing arm to carry out forced guidance and mixing for the materials in the tank. The drum type mixer is also called as self-falling mixing drum, with the help of the mixing blade installed in the mixing drum, the material is lifted, and the material falls by its own gravity, and produces axial string movement, so as to achieve the mixing effect.
Compared with the two, the forced mixing effect is strong, generally in 30-60 seconds of mixing time can be mixed into uniform concrete, mixing special or special concrete, it takes a longer time. The mixing time of the self-falling type needs to be doubled or even longer, and the mixing of special concrete is difficult or even impossible.
Double horizontal shaft and single horizontal shaft
The forced concrete mixer can be divided into two categories: single horizontal shaft and double horizontal shaft. Compared with the single horizontal shaft type, the linear speed of the mixing blade is lower, and it is resistant to wear. The wear degree of lining plates in each part of tank body is similar, and the service life of lining plates is long and the economy is good. The drive device can use two sets of synchronous operation, which is more conducive to the supporting conditions and product serialization development of large specifications models, therefore, the double horizontal shaft mixer has become a widely used mixing station host.
Several Special Concrete Mixing Plant
Marine mixing plant
Marine concrete mixing plant is specially used for the construction on water. The equipment is a large concrete mixing equipment which integrates material storage, measurement and mixing. The characteristics of the product are: equipment installed on the ship, material storage, metering, mixing, pumping in one, suitable for wide water concrete construction; The measuring structure of draw-rod scale is adopted to meet the requirements of measuring accuracy when the ship is swinging. The sewage is recycled to meet the environmental protection requirements of water surface construction. It is mainly applied to the concrete production of cross-sea and cross-river Bridges and coastal and river-side ports and wharves.
Mobile mixing plant
Mobile concrete mixing plant compact structure, aggregate, weighing, lifting, mixing as a whole, fast and convenient movement, save labor and time, improve productivity. The equipment is equipped with rear axle, which can be quickly transferred to the site under the traction of the tractor. With convenient transfer, installation and debugging fast; No concrete foundation is required. It is suitable for construction projects, hydropower, roads, ports, Bridges and other engineering construction and concrete construction in the early stage of large-scale projects.
Free foundation concrete mixing station
The new free foundation concrete mixing plant is composed of material supply and metering system, mixing system, electrical control system, gas path control system, etc., which is used for construction above medium scale, hydropower, highway, port, bridge and other engineering construction and medium concrete prefabricated plant and commercial concrete production plant.
