What is a Concrete Mixer?

A concrete mixer mixes cement, aggregates and water and produce concrete mechanically. There are various types of concrete mixers available which makes concrete production quick and economic.

Types of Concrete Mixers

At that place are two broad types of concrete mixers:

  1. Batch mixers
    • Drum Types Mixer
      • Tilting drum mixers
      • Non-tilting pulsate mixer
      • Reversing drum mixer
    • Pan Type Mixer
  2. Continuous mixers

Different Types of Concrete Mixer or Concrete Mixing Machines

Batch Concrete Mixers

Batch mixers are widely used machines for concrete mixing. Concrete mix obtained past this mixer is collected batch by batch and time past fourth dimension. Then, it is chosen as batch mixer. Later on pouring all the materials into pan or drum, it mixes all of those for some time and finally discharges. This process is repeated until required amount of concrete mix is obtained. In full general Batch mixers are two types.

  • Drum type mixers
  • Pan type mixers

Drum Blazon Mixers

In case Drum type mixers concrete ingredients are mixed in a drum which is actually in double conical frustum shape. Drum types mixers are classified into three types:

  • Tilting drum mixers
  • Non-tilting drum mixers
  • Reversing pulsate mixers

Tilting Pulsate Mixers Tilting pulsate mixer means the drum will discharge concrete by tilting downwards. It is rapid discharge process and used for larger projects. Rapid means information technology delivers concrete past gravity that is tilting the drum downwards because of this the concrete mix obtained will be not subjected to segregation. Low workable concretes which contains large sized aggregates of size greater than vii.5cm are also mixed efficiently with this tilting blazon mixers. Just the mixing efficiency depends on some of the factors as follows:

  • Shape of the drum
  • Bending of the drum
  • Size of blades
  • Bending of blades

The just disadvantage of this mixer is sticking of concrete to bottom of drum. To overcome this a method called buttering of mixer is applied in which some corporeality of cement mortar is mixed in the mixer before mixing commencement batch of concrete. Tilting Drum Mixers Non-Tilting Drum Mixers Non- tilting pulsate mixers are non immune to tilt and the drum rotates well-nigh its horizontal centrality. For the discharge of concrete a chute is bundled in inclined position which will receives the concrete mix from drum and discharges out. In this example, the drum is opened at two ends and consists blades insides when materials are poured through one end and mix is nerveless through another end. Rapid discharge of concrete is non possible in this case. Due to this delay, the physical may be vulnerable to segregation. The larger size aggregate is not discharged easily with the mix. So, size of amass mot more than than 7.5cm is preferable for this blazon of mixers. So, this type of mixers are generally used for small-scale projects. Non-Tilting Drum Mixers Reversing Drum Mixers Reversing pulsate mixers are similar to non-tilting type mixers but in this example reversal of rotation takes place for different activity. The drum has two openings, ane stop is for pouring materials and other end is for belch of mix. The drum rotates most its horizontal centrality. The rotation of drum takes place in 1 direction for mixing and in opposite direction for discharging. Two unlike set of blades are bundled for mixing and discharging. They are suitable for dry physical mixes. Reversing Drum Mixers

Pan Blazon Concrete Mixers

Pan blazon mixers consists a circular pan in which physical is mixed. The mixing is done by blades which are arranged in star shape within the pan. There are two types of pan mixers are available. In ane case, the circular pan is constant and only star blades rotate near vertical axis of pan. In the other case, circular pan rotates while the blades are at static position. But in both cases, the mixing is efficient and concrete mixture is collected through key hole provided in the pan. The rotating star blades contains special blades called scrapper blades which volition make concrete not to stick to the pan. The blades can besides be adjusted in height then, in that location is no room for concrete to store in the pan. We tin can say among the all types of batch mixers pan blazon mixer are more efficient. Pan Type Concrete Mixers

Continuous Physical Mixers

Continuous mixer, the proper noun itself telling its duty that the loading, mixing and discharging of mix is continuously done until the work is complete or work break occurs. The loading of materials is done continuously by screw feeders. Continuous mixtures are used for very large projects such as dams, bridges, construction of loftier rise buildings, etc. Continuous Concrete Mixers Read More: Concrete Figurer – Calculate Physical for Slab, Beam, Cavalcade and Footings Physical – Definition, Grades, Components, Industry, Construction and Articles What are the Types of Physical?
