DIY forced-action concrete mixer – an assistant in construction

The correct tools can make all the difference in the construction industry. One such tool that can significantly raise the effectiveness and caliber of your concrete projects is a forced-action concrete mixer. A forced-action mixer thoroughly mixes the components of concrete, as opposed to conventional drum mixers, guaranteeing a more consistent and dependable mix. Building your own forced-action concrete mixer can be a rewarding and affordable project for individuals who enjoy do-it-yourself tasks.

Although building a forced-action concrete mixer may seem difficult at first, anyone with a basic understanding of technology can complete the project with the correct tools and advice. A revolving drum with fixed paddles is used in this type of mixer to ensure that all ingredients are mixed evenly, producing high-quality concrete that is perfect for a variety of construction tasks.

Constructing a homemade mixer has various benefits. It enables you to modify the device to meet the demands of your particular application and project. In addition, building a forced-action mixer yourself can save you money compared to buying a commercial one and provide you with the satisfaction of creating a useful tool for your construction projects.

We’ll walk you through the process of building a homemade forced-action concrete mixer in this article. We’ll go over the supplies you’ll need, detailed instructions, and advice on how to make sure your mixer works properly. This mixer will be an essential tool in your toolbox whether you’re planning major construction projects or minor home improvements.

Types, diagrams, drawings of concrete mixers

The family budget is severely impacted when renting a self-loading concrete mixer, buying concrete from a factory, or renting a car mixer. Volumes that "cannot be produced at once" and a high price for concrete are starting to appear. When placing an order, make sure the volume matches the concrete mixer’s capacity.

Heavy machinery just cannot get through the densely populated residential building that may house the construction site. Those who frequently work with the solution find their problems resolved by such a homemade concrete mixer.

Modifications of concrete mixers

Concrete mixers are separated into gravity and forced categories based on how solutions are obtained.

  • With gravity, everything is clear, here it uses its own weight (gravity) and the force of attraction, causing the components to roll over and mix. Blades are welded to the inner walls, which additionally help with mixing.

  • Simplicity of design, low power consumption during operation can be attributed to the advantages of these mixers. You can only dream of high-quality concrete obtained in these units if you need to make paving slabs, cinder blocks or supporting structures. You can pour a foundation, make blind areas from this concrete.

Be aware that gravity-type units don’t care whether you mix crushed stone or gravel.

They pay for themselves in a few weeks if used extensively.

  • For clarity of studying a concrete mixer operating on the principle of forced action, a mixer is shown in the photo. Their methods of obtaining solutions are similar. Inside the container of such a concrete mixer, fixed motionless, the blades rotate on the shaft.
  • The productivity of concrete mixers of this operating principle is several times greater than that of gravity modifications and the quality of the solutions is better.

Be aware that a low-power concrete mixer, whose forced action operation produces 0.5 m³ of concrete in 5 minutes of labor, can accomplish the same task in 0.5 hours with a gravity mixer.

  • A forced concrete mixer made by hand is made with a horizontal or vertical shaft, which determines its shape.

Homemade concrete mixer from a home workshop

Drawings and design elements used in the forced concrete mixer’s assembly must be considered in each unique situation. It is evident that an owner of a homemade concrete mixer pays significantly less.

Although home products will not look or function as well as factory units, they do solve the issue of being able to obtain concrete at home that meets the necessary quality standards.

Make a schematic of a forced-action concrete mixer and select the parts and equipment.

A forced-action concrete mixer’s drawing provides a detailed depiction of the unit’s measurements as well as the parts’ specifications.

After completing the drawings and diagrams, you can begin buying the required parts or locate something in a "garage," which is a type of at-home workshop.

Components and parts Tools
A round container, 1.2 m in diameter and 1.4 m in height Welding machine
2 shafts with a ball design. Balls must be purchased D = 50 mm, factory-made, hardened. They will not deform during operation Angle grinder
It is better to take pulleys for the gearbox for 3 C-profile belts. You can also take one B-profile, but there is a chance that it will slip during operation Drill
Bearing cage D = 140 mm in the amount of 2 pieces Keys
The gearbox can be found in the garage. If it is rusty on top, then it is okay. It is necessary to inspect its insides. It is important that the shafts have clear "teeth" and unworn bearings Screwdrivers
3 kW electric motor, 2.2 kW is also possible, but at full load, a homemade unit with forced action will "slip" due to insufficient engine power Pliers
Coupling
Blades from a spring, pipe
Metal corners
Channel

The design of concrete mixers presents no unique challenges. For the majority of parts made at the factory, home craftsmen who have long since transitioned into the category of craftsmen can suggest the best alternatives.

Constructing a homemade forced-action concrete mixer can revolutionize construction projects by providing an economical and effective means of blending concrete. A forced-action mixer, in contrast to conventional drum mixers, uses an internal rotating mechanism to force the concrete mix to blend evenly, ensuring thorough mixing. As a result, the mixture becomes more uniform, which is essential for the durability and strength of concrete structures. Making your own mixer is an excellent investment for both small- and large-scale construction projects since it not only saves money but also provides you with a dependable tool that increases productivity on the job site.

Component Description
Drum The drum is where the mixing happens. It should be durable and large enough to hold the desired amount of concrete mix.
Mixing Paddles Mixing paddles inside the drum ensure even mixing of the concrete components, preventing lumps and ensuring a uniform consistency.
Motor The motor powers the mixer. A strong motor will provide the necessary force to mix heavy concrete efficiently.
Frame The frame supports the drum and motor, providing stability during the mixing process.
Wheels Wheels make it easy to move the mixer around the construction site, adding portability to the design.
Control Panel The control panel allows the user to operate the mixer, adjusting speed and duration of mixing as needed.
Safety Features Include safety features such as emergency stop buttons and protective covers for moving parts to ensure safe operation.

Constructing a DIY forced-action concrete mixer can be a fulfilling endeavor that results in increased productivity and cost savings for building sites. Although pre-assembled mixers can be bought, a do-it-yourself version gives you the freedom to modify the device to meet your unique demands and volume specifications. You can make a sturdy and dependable tool for your construction projects by carefully choosing the appropriate materials and adhering to a well-thought-out design.

Although it takes some technical know-how and basic tools to construct, the end product is a powerful mixer that can handle different kinds of concrete mixes. A homemade forced-action mixer can last for years with regular maintenance, providing reliable performance and minimizing the amount of manual labor required to mix concrete.

Building your own forced-action concrete mixer is a useful project that can improve your construction skills, regardless of your level of experience. By devoting time and energy to this project, you will acquire a useful tool that will help you work more quickly and easily on construction projects in the future.
