Types of Concrete Mixer

Concrete mixer is an indispensable equipment in the construction industry, which is mainly used to mix and blend cement, sand aggregate and water into concrete mix. Types of concrete mixers can be subdivided according to different working principles, structural characteristics and use requirements. The following is a detailed introduction to the several types of concrete mixer you mentioned:

Classification according to working principle:

– Forced concrete mixer

Working Principle: Through the rotation of two horizontal mixing shafts inside the mixing silo, it drives the mixing arms and mixing blades on the mixing shafts, and carries out forced mixing for all kinds of materials entering the mixing silo.

Characteristics: strong mixing effect, suitable for mixing dry concrete and light aggregate concrete, short mixing time, high productivity, flexible operating system, clean discharge. However, the drum and blade wear faster, mostly used for concrete with aggregate below 25mm.

– Self-falling concrete mixer

Working principle: the mixing drum rotates at an appropriate speed, and the materials are lifted to a certain height by the blades in the mixing drum and then fall down by their own weight, so as to achieve the effect of uniform mixing through the process of repeated lifting and falling.

Characteristics: Long history, simple structure, easy to use, mainly used for mixing general plastic concrete, adapted to decentralized or centralized use on the construction site. However, its mixing efficiency is relatively low, and requires more labor to cooperate.

Classification according to structural characteristics:

– Horizontal shaft concrete mixer

Types: including single horizontal shaft and double horizontal shaft mixer. Among them, single horizontal shaft mixer is mainly used for mixing concrete, mortar and other materials.

Characteristics: good mixing quality, high production efficiency, low energy consumption, low noise, reasonable structure, easy operation, fast discharging speed, long service life of liner and blade, easy maintenance.

– Planetary concrete Mixer

Working principle: while the stirrer rotates around the kettle axis, it also rotates around its own axis at high speed with different rotational speeds, so that the materials make complex movements in the kettle and are subjected to strong shearing and rubbing.

Characteristics: high mixing efficiency, suitable for all kinds of high viscosity and high solid materials, widely used in chemical industry, light industry, foodstuff, battery, pharmacy, building materials, pesticide and other industries. However, its structure is complicated and the price is high.

Classification according to the working mode:

– Intermittent concrete mixer

Characteristics: raw materials in a longer period of time uniformly into the mixer, the finished product is also stable loading, stable work, high production efficiency. The whole machine covers a small area, easy to install and dismantle.

– Continuous concrete mixer

Characteristics: capable of continuous feeding, watering, mixing and discharging, high production efficiency, suitable for large-scale concrete production. However, it has higher requirements for sealing to avoid concrete penetration into the shaft end sealing device.

Classification according to the installation mode:

– Fixed concrete mixer

Characteristics: The installation position is fixed, usually installed in the concrete mixing plant or construction site and other fixed places. Suitable for long-term, large quantities of concrete production tasks.

– Mobile concrete mixer

Characteristics: easy to install, can be moved to the required place at any time for mixing operations. Suitable for temporary, small-scale concrete production tasks or occasions that require frequent movement of the workplace.

In summary, there are many types of concrete mixer, each with its own unique working principle, structural characteristics and advantages of use. When choosing, comprehensive consideration should be made according to specific construction needs, production efficiency, cost budget and other factors.
