The gravity concrete mixer is a mainstay on many construction sites when it comes to efficiently mixing concrete. This kind of mixer mixes the ingredients using the straightforward but powerful principle of gravity. It’s a reliable, long-lasting solution that has been used for many years. Gaining a better understanding of its operation can help you appreciate its importance in construction projects.
A tilting and rotating drum is a common feature of a gravity concrete mixer, which uses gravity to help mix cement, sand, gravel, and water. The components tumble and combine as the drum rotates, guaranteeing a homogeneous and even concrete mixture. This design is a preferred option for both small- and large-scale projects because of its dependability and simplicity.
The simplicity of use of a gravity concrete mixer is one of its main advantages. Compared to more sophisticated mixers, it has fewer moving parts, which makes it less prone to malfunction and frequently requires less maintenance. This makes it a sensible option for a lot of builders and do-it-yourselfers who want to finish the project quickly and easily without having to deal with complex equipment.
The gravity concrete mixer offers a dependable and simple solution for your concrete mixing needs, whether you’re building a new driveway or taking on a larger construction project. Its tried-and-true functionality and design keep it a useful tool in the construction sector.

Design and principle of operation
The drum is the primary component of any Bruder concrete mixer. It is equipped with unique blades that stop the material from rolling off the walls. Within the drum, a gravitational field forms as soon as the device starts to rotate on its axis. This is the reason for the material’s powerful fall off the walls. The following formats are possible for machine models:
- a device with a pear-shaped drum that tips over;
- a device with a pear-shaped drum that does not change its position;
- design with a tilting drum, the conical parts of which are connected by a wide cylinder.
It is important to keep in mind that every model has a unique volume, design, and set of features. Based on this, you can choose a concrete mixer.
The bruder gravity concrete mixer works on the following principle: the mixture will mix considerably more quickly when the rotating bowl is positioned at a specific angle. Simultaneously, you can improve the mixing quality by adjusting the angle of the drum. Remember to compute the required materials while paying attention to the ratios. The concrete will be of lower quality if the computation is incorrect.
Advantages and disadvantages
Positive and negative aspects can be found in a gravity concrete mixer. Benefits
- ease of transfer and transportation to another place;
- compact size;
- reliable installation of the device;
- simple design that does not require special knowledge in use;
- unloading the drum in a short period of time;
- low energy intensity.

- problematic distribution of additives in the mass.
Utilizing such equipment is generally justified and can pay for itself in a matter of weeks.
Using gravity to blend the ingredients, a gravity concrete mixer is a basic yet efficient tool for mixing concrete. It has a tilting and turning rotating drum that mixes concrete thoroughly with little effort. This kind of mixer is a popular option for both professionals and do-it-yourselfers because it is perfect for smaller projects and provides an easy, affordable way to produce high-quality concrete.
Price
A large variety of concrete mixers with varying volumes, models, and performance levels are available on the market today. You can buy the least expensive cyclic concrete mixer for home use for about 5,000 rubles. It is small, so you can store it anywhere and use it infrequently.
More professionally involved in construction can purchase equipment for as little as 300,000 rubles. A machine like this will be more resilient to wear and tear.
Kinds
Before choosing the equipment you need, familiarize yourself with the vast array of types and their attributes. Naturally, it is possible to construct a concrete mixer by hand. However, there are many manufacturers offering high-quality, robust machines on the contemporary market. The principal ones are VM-125, SBR-430, and SB-174:
- SB-174 is used to prepare mobile solutions to fill a small area. The drum loading can be up to 100 liters, and the volume of the finished solution is 65 liters. The weight of such a concrete mixer is 150 kg.
- SBR-430 can be used individually or in factories, but during operation the ambient temperature must not be lower than 5 degrees, otherwise the machine will not work. The volume of the finished mix of SBR is 190-200 liters.
- VM-125 has a weight of 53 kg, it is used to prepare concrete solutions or mix dry components. 125t have a drum with a volume of 125 liters.
Apart from these, there exist other varieties that possess specific attributes:
- The gravity concrete mixer SB 170 Gambit is a convenient equipment suitable for the production of absolutely any mixtures. At one time, the gravity concrete mixer SB 170 Gambit can mix about 120 liters of concrete, which is enough to fill a small area. Gambit concrete mixers are mobile, and their transportation is also easy. The weight of the concrete mixer is 100 kg. It has a concrete feed from both sides.
