What Is A Reversing Drum Mixer?

A concrete mixer known as a reversing drum mixer or non-tilting mixer creates concrete in individual batches.

This mixer rotates the drum on its axis as ingredients are added through an inlet at one end and then discharged through an outlet at the other end of the drum.

Reversing Drum Mixer Mixing Action

Reversing drum mixers are an efficient and cost-effective solution for mixing concrete, with a capacity of up to 9 m³ and producing mid-quality concrete in only 40 seconds.

The mixer is equipped with blades mounted on the inside surface of the drum, which lifts and drops materials as it rotates, providing for thorough mixing; once materials are sufficiently mixed, the blade arrangement pushes them through to the discharge end.

The drum rests on rubber or polyurethane wheels, eliminating direct contact between stationary charge/discharge chutes and the rotating drum, thereby reducing wear and providing low maintenance and noise reduction.

Additionally, this efficient mixing process reduces wear on the liner, making it a reliable option for many construction projects.

How Does Tilting Drum Mixer Works?

A tilting drum mixer is a type of machine that discharges concrete by tilting the drum downward. This method is fast and efficient and is commonly used for large construction projects.

Due to the downward tilt of the drum, the concrete is delivered through gravity, preventing segregation in the mixture.

What Are The Types Of Concrete Mixer?

Concrete mixers come in several types. One main category is batch mixers, which can be further divided into two subcategories: drum mixers and tilting drum mixers.

Drum mixers feature a mixing drum with a double conical frustum shape, where the ingredients are combined.

Tilting drum mixers, on the other hand, have the added advantage of being able to quickly discharge the mixed concrete by tilting the drum downwards, making them well-suited for larger construction projects.

How Many Types Of Mixers Are There?

There are three commercial mixers available–dough, planetary, and vertical cutter mixers.

Dough mixers are versatile equipment that use a spinning dough hook to knead and combine ingredients into mixtures suited for baking.

Planetary mixers offer more power than their dough mixer counterparts, with a heavy-duty motor capable of easily handling denser batters like cookie dough or pizza crusts.

Lastly, Vertical Cutter Mixers are designed to blend ingredients quickly, especially those that require constant stirring and agitation for the mixture to emulsify properly. Each type of mixer has its advantages and can be beneficial depending on the requirements of each specific application.

How Does A Non-Tilting Drum Mixer Work?

A non-tilting drum mixer works by rotating the entire drum around its axis so that materials can be loaded through one end and discharged through the other. This is done in single batches, with the drum continuously rotating so that the material inside gets properly mixed.

A charge chute at one end of the drum and a discharge chute at the other allows for convenience when loading and unloading without lifting or tilting any heavy items.

The design of these mixers also helps to cut down on potential spills and reduce dust particles from entering the mixture, making it more efficient and safer for work environments.
