Classification Of Drum Type Concrete Mixers
Drum type concrete mixers are important part of the concrete mixers available today. They are most suited for small to large capacity machines. As the name suggests, the mixer is drum type with an opening in one end or in some cases two ends. The material used to make concrete (aggregates, sand, cement, water) are mixed inside the drum as the drum rotates. But it is not as simple as it seems there are designed flights inside the drum that help in mixing and unloading the contents. The mixer is filled and emptied by rotating it in clockwise and anticlockwise direction, tipping it (tilting) or opening it. Rotation is controlled and suitable for better mixing.
Drum concrete mixers are known to have the lowest operating and maintenance costs among all mixers. They are used and preferred when the cost of production is one of the major factors. Even high volumes of concrete can be produced by the use of these mixers.
Classification of concrete mixers:
Concrete mixer classification is based on the type of mixers they use. Major classification of these mixers can be in two types:
Tilting mixers
Non tilting mixers
Mixing plants have the task of concrete mixing. The idea is to mix the concrete in an efficient manner and have a quality end product. The product for concrete mixing should be suitable for efficient mixing and high quality output.
Tilting mixers:
As the name suggests the mixers will usually need to tilt during its course of action. They will have a single opening for feeding the materials. They usually work at an angle of 15 degrees Celsius and discharge is facilitated by the same opening in the drum mixer. They can handle large size of aggregates easily and the discharge is faster in such type compared to the non tilting type. Large size particles can be easily used with these mixers.
