Finding The Right Mix With A Portable Mixer

Portable mixers can be a gamechanger on any job – large or small.  A mason can easily mix small or large mortar batches in a mixer instead of using a mixing tub or wheelbarrow.   Since portable mixers have wheels, many can be towed behind a work vehicle or easily rolled out from the back of a work truck. 

These portable machines allow a mason to mix mortar or concrete on the job, which improves job efficiency, keeps costs low, and reduces worker fatigue associated with manual mixing. But with so many portable mixers on the market today, how do you know which is the right fit?


There are many factors to consider when you are picking a suitable portable mixer for your needs. Mixers are similar to tools; you may need more than one based on the type of project and work volume. Some key considerations when choosing a portable mixer include;


Gasoline engines or electric motors power portable mixers. 

Gasoline engines typically power larger mixers. Since they rely on gasoline to run, they are self-contained and are not subject to jobsite conditions. However, the exhaust produced by a gasoline engine makes it difficult to use indoors. They can also be loud.

While electric motors are typical in smaller, portable mixers, they are an option on some larger mixers. An electric motor is typically quieter than its gasoline-powered counterpart. Since they don't produce dangerous exhaust, a mason can use them indoors.  An electric motor relies on electricity to run; if a job site doesn't have electricity or its outlets do not produce the correct voltage, a portable mixer with an electric motor may not work.


A mixer’s drivetrain can impact its efficiency and cost.  Portable mixers use drivetrains that rely on belts, gears, or hydraulics.

  • Belt drivetrains are most commonly used in portable mixers. They are the least costly configuration for a portable mixer. Belt drivetrains typically have a mixing capacity of up to nine cubic feet. 

An electric motor or gasoline engine is connected to the gears and paddles in this configuration, mixing materials using belts. 

Belt drivetrains can get plugged if workers don't use enough water when mixing, which can cause costly delays as work has to stop to remove the dried material from the machine.  These drivetrains result in higher maintenance costs as the belts are susceptible to breaking.

  • Gear drivetrains offer similar cost-saving benefits as belt drivetrains. The use of mechanical gears delivers more power to the mixing function, with some having a capacity of up to 12 cubic feet.  Some may use a hybrid model incorporating gears and belts, which helps keep costs lower.  Gear drivetrains encounter similar maintenance. The mixer is susceptible to plugging if there is not enough water used when mixing. Gears and other mechanical components may break due to usage.
  • Mixers with hydraulic drivetrains bring many benefits. By relying on hydraulics for the mixing function, there is less chance of belts and gears breaking.  In the event of a plug, the hydraulic drivetrain can reverse the paddles to clear out the blockage, which saves both time and money as work doesn't need to stop while the mixer is cleaned.  Hydraulic machines may also cause less worker fatigue as they can be loaded at a lower height. Those equipped with a hydraulic drum lessen the physical burden on workers. 

Hydraulic machines cost more money. However, their general equipment repair and maintenance costs are far less than belt and gear drivetrains. 


You can find a wide variety of portable mixers on the market today.  They range in capacity and configuration.
