Small size portable concrete mixers are essential equipment for mixing concrete on-site in a small volume. They have wheels or a carrying frame. Some even have a flat belt for dragged and moved along with the materials. These mixers types combine water, aggregate, cement, and sand to produce uniform concrete for small-scale projects.
Generally speaking, there are two main types:
In addition to the two main types, small portable concrete mixers can be classified based on power source.
The specifications of small portable concrete mixers for sale vary depending on the type and model. Key specifications include the mixing capacity, engine power, weight, as well as other dimensions, like length, width, and height.
Generally, the mixing capacity of a small concrete mixer ranges from 0.25 to 3 cubic meters per batch. The mixing capacity determines how much concrete will be produced at a time. When choosing a small concrete mixer, buyers should consider the amount of concrete required and how frequently the mixer will be used.
Small portable concrete mixers typically run on diesel and petrol engines or electricity. Worksites often use fuel-powered mixers, while residential constructions can use electric-powered ones. The engine power of fuel-powered mixers ranges from 4 to 8 kW, while electric-powered ones range from 3 to 7.5 kW.
A small size portable concrete mixer can weigh anywhere from 80 to 1,000 kg. Its dimensions are, in general, 2.5 meters in length, 1.5 meters in width, and about 1.5 meters in height. Weight and dimensions of the mixer are crucial because they determine how portable the mixer is and how easily it can be stored.
The key to maintaining a small concrete mixer is regular inspection and cleaning. Mixing blades should be inspected frequently to see if there's any damage or wear and tear. Any obstructions to their movement should be removed right away. Portable concrete mixers are designed so that pouring outlets or drain pits are always positioned downwards. Doing this will help prevent clogs. Small concrete mixers should be cleaned and unclogged regularly, especially after pouring a single batch of concrete. Once the solution stops draining, cleaning can be easier and quicker.
Small concrete mixers should always be lubricated to prolong their lifespan. Lubrication is especially critical for the gearboxes, supporting wheels, shafts, and bearings. Many small concrete mixer manufacturers recommend lubrication every week, but this may vary depending on the usage.
Always check the hoses and belts for any cracks or damages before using the mixer. Air pressure in the wheels should also be checked to avoid difficulties transporting the mixer from one place to another. Fuel and water hoses and the electrical connections should be inspected regularly, too.
Small portable concrete mixers are mainly used for mixing concrete for smaller construction projects. However, the applications go beyond that.
Residential construction
Small portable concrete mixers are used for DIY projects and in smaller-scale construction where large concrete batches are not needed. In that case, the mixers are used to mix concrete for applications such as:
Road maintenance and paving
Maintenance of rural roads and local roads does not require large-scale machines and staff. Construction teams can use small portable concrete mixers to make concrete on the spot for filling potholes, cracks, and minor repairs.
Mortar mixing
Small, portable concrete mixers can be used to mix mortar for applications like bricklaying, tiling, and stonework.
Plaster mix
Small mixers can also be used to make customized mixes for plasters used in coating walls and other surfaces.
Landscaping
When undertaking landscaping projects, workers can use small portable mixers to make small batches of concrete for decorative elements such as garden paths, benches, planters, and other hardscape features.
Cultured marble and onyx mixing
Small mixers can be used in the production of cultured marble, onyx, and other composite stones. Such materials are used in decorative architectural elements, countertops, and customized molds.
The following tips will help construction business owners, contractors, and wholesalers when choosing a portable concrete mixer.
Mixers for Small Jobs
M''flexible mixers like the ''Belle Minimix 150''' are perfect for small construction tasks that require portable mixing. They are ideal for DIY projects, repairs, laying pathways, brickwork, and small-scale building jobs.

Mixing Capacity Required
Determine the amount of concrete that is needed at a time. Small concrete mixers come in different sizes ranging from one-third of a cubic meter to four cubic meters. Farmers, for example, may only need to mix cement for one meter at a time, while small construction companies or contractors may need to mix up to three cubic meters at a time. Consider the equipment''s mixing capacity when choosing a portable concrete mixer.
Power Source
Small concrete mixers have different power sources. Some of them are gasoline-powered, others are diesel-powered, while some are electric mixers. Think about the job site environment and the availability of the power source when choosing a portable concrete mixer with a specific type of power source.
Simplicity and User-Friendly Design
When choosing a small concrete mixer, consider the usability of the equipment and the operational comfort it provides. Go for the products that have a convenient loading and unloading process, clear control panels, good visibility, and intuitive functions.
