concrete mixer

A concrete mixer (also called a cement mixer) is equipment that combines cement, aggregate such as sand or gravel, and water to form concrete. A concrete mixer uses one of the most primitive techniques of mixing aggregate with sand and water to form concrete. Typically, a concrete mixer uses a revolving drum to mix the components. For smaller volume works portable concrete mixers are often used so that the concrete can be made at the construction site, giving the workers ample time to use the concrete before it hardens.

 

Concrete mixers have evolved and they are available in three forms: Concrete mixers without hopper, Concrete mixers with mechanical hopper and Concrete mixers with hydraulic hopper.

 

Concrete mixers without hopper:

This is basically a 10/7 Cft. capacity machine. The lower portion of the mixing drum with its integral toothed gearing is precisely cast from high-grade cast iron is well balanced for vibration free performance. The draw bar with turn table on the front axle is for easy towing and a broad wheel base is provided to ensure better stability. The mild steel fabricated upper cone of 3.15 mm thick is riveted on the drum base. The mixing drum is mounted on rigidly fabricated mild steel cradle-like yoke.

 

This can be tilted on either side by a hand wheel for variable mixing positions.

 

Concrete mixers with mechanical hopper:

This machine is similar to the mixer without hopper except for the fact that it uses a wire rope to feed the material to the mixer drum. Its special mixing worm design ensures proper and through mixing of concrete. The mixing drum is mounted on rigidly fabricated mild steel cradle-like yoke.

 

This can be tilted on either side by a hand wheel for variable mixing positions. The drum is fed through hopper. The feeding angle of the hopper has been designed to feed the mixing drum at a higher speed, thereby further increasing efficiency.

 

The bottom thickness of the mixing drum is 15-20 mm which is extremely durable and can resist wear and tear. This is evident from the fact that the C I casting drum weighs 230 kg.

 

Concrete mixers with hydraulic hopper:

Hydraulic operated hopper uses a hydraulics to feed the material to the mixing drum.

 

The lower portion of the mixing drum with its integral toothed gearing is precisely cast from high-grade cast iron is well balanced for vibration free performance.

 

Special mixing worm design ensure through mixing of concrete. The mixing drum is mounted on rigidly fabricated mild steel cradle-like yoke. This can be tilted on either side by a hand wheel for variable mixing positions. The drum is fed through hopper. The feeding angle of the hopper has been designed to feed the mixing drum at a higher speed, thereby further increasing efficiency.
