10 Questions to Ask when Buying a Volumetric Mixer

The volumetric concrete mixer business is a rather unique one. It may sometimes feel overwhelming to try to get into this side of concrete production. However, the business can be broken down to a few questions that can be relatively simple to answer. When considering a volumetric mixer, ask your sales contact these questions:

  1. How much concrete do I need to produce to be profitable?

Maybe the most important question; How do I make money? If possible, ask your sales rep to take you through a ROI (Return on Investment) sheet to truly understand the finances. To determine this, there are a few things we need to analyze:

  • What are your annual business operating expenses?
  • How much does it cost you to produce one cubic meter/yard?
  • How much can you sell one cubic meter/yard for?
  • How many cubic meters/yards can you pour in a year?

Although these can be great numbers to reference, you must also make sure you understand how you are structuring your business. For example, if your goal is to supply yourself with concrete, those numbers will not be able to take into consideration how much time you saved, how many additional jobs you will be able to take on each year, and how your crew’s efficiency has been affected by not having to wait on concrete.

As a rule of thumb, if you can approach 2,000 cubic meters a year or 2,500 cubic yards a year, you should be able to turn a profit while paying off your equipment on a 5-year payment period.

  1. How do I choose the right chassis?

Bay-Lynx can provide you with a chassis brand of your choice or can work with your local truck provider if you wish to use them as the source of your chassis.  We can provide axle ratings and computer simulated weight distributions for you, so you know what your legal carrying capacity is for your model.   All of the major truck brands can provide a suitable chassis but there are things that we recommend you look for when spec’ing a truck:

  • Transmission: if possible, we recommend an Allison Transmission as an automatic transmission is the most effective way to have a roll-and-pour feature to allow your truck to move without shutting down your mixer.
  • Engine: Over 400 HP recommended (but not required).
  • Frame clearance: Depending on the model selected but talk to your salesman on the CA/CT length required for your model.


  1. How much material can I carry?

This varies depending on your federal/provincial/state transportation laws. Sometimes customers say they want to carry 10 meters/12 yards of material, but it is our responsibility to inform them that just because they can fit enough material in their mixer for 10 meters/12 yards does not mean that they will be road legal. Consult with your local sales rep to see how much material a volumetric mixer can carry in your area.

  1. What knowledge should my operator have?

An increasingly challenging dilemma facing volumetric companies is finding skilled operators. We at Bay-Lynx have aided to combat that by automating much of the set-up normally needed to be done by the operator. However, your ideal operator can identify concrete quality/slump by looking at it. Also, your operator should have the skills for machinery operation rather than solely truck driving.

  1. What concrete can my volumetric mixer produce?

Pretty much any concrete a ready-mix plant can produce. Make sure you have this discussion with your sales rep as he can cover all your concrete needs and mix designs as it relates to your mixer. If you plan on producing coloured concrete or fibre reinforced concrete, your salesman can equip a fibre feeder and colour feeder to your machine. Treat this as an additional revenue source. Bay-Lynx machines have the ability to mix zero slump mixes as well.

  1. How do I choose my materials?

Contact a local quarry for your sand and stone materials. Any time you change suppliers of your materials, your machine should be re-calibrated to fit the new material density and shape. For more on aggregates, see our article here.

  1. What about cement storage?

Cement storage comes in two forms: silo and bagged cement. Bagged cement can be useful for delivering cement on site.  Be cautious that your bagged cement does not come into contact with any moisture. Bagged cement can be loaded with a forklift/loader.

Although bagged cement might seem more convenient, they are much more expensive in comparison to buying high quantity cement that is loaded straight into a silo.

  1. What about winter pouring?

If you live in a colder climate winter pouring may be a concern. We recommend limiting usage in freezing temperatures. If it is necessary for you to keep busy in the colder season, here are some things to consider:


Aggregates are very important to keep controlled for temperature. The last thing you need is clumps of frozen material preventing your material from being metered properly. We recommend storing your material on heated pads with a tarp to protect from any moisture. If heated pads are not a possibility, try storing your material in a heated indoor facility the night before usage.

Water and Admixes:

Load warm temperature water in your tank. The water tank can withstand temperatures up to 140 degrees Fahrenheit (60 degrees Celsius). Do not try to exceed that mark.

Another option would be to install a heat exchanger that reroutes the engine coolant with your water. This technique can maintain your water temperature but is not reliable for heating your water temperature.

Excess admixtures should be drained after the workday.

  1. What does the maintenance look like?

The most important component of the mixer is the auger as it is the only component that comes in contact with the concrete. Your wear blades should be changed at least once per season depending on the mix designs you are pouring. Low slump mixes are subject to more wear than high slump mixes. Also remain active on your lubrication schedule. Your machine requires weekly lube points as well as a couple of daily lube points to make sure bearings are kept in good condition.

  1. What about financing?

Financing can be quite simple as truck dealers are happy to finance the entire package. This is usually the recommended route to keep things simple for the customer. Bay-Lynx works with several sources for financing and can put you in touch with them anytime to help with your financing needs.
