Choosing Between Single & Dual Shafted Food Waste and Trash Grinders

The difference between single and dual-shafted wastewater/food waste grinders is that dual-shafted food waste grinders are able to process larger volumes of a wider range of solid waste materials.  Dual-shafted food waste grinders that are low-speed and high torque are the clear choice for many industries putting out large amounts of waste on a daily basis, such as petroleum, wastewater, agriculture, food processing, manufacturing, ship food waste and MARPOL compliancy, e-waste destruction and more

However, not everyone needs a food waste grinder capable of shredding everything from rags, rocks, and wood to clothing, plastics and other debris.  Sometimes a single-shafted food waste grinder is enough to meet the desired outcomes people have.  Here are the five questions you must ask yourself before choosing a food waste grinder:

1. What types of waste materials are you processing?

Different grinders have different grinding capabilities.  And so, it’s important that you understand exactly which waste materials you are looking to reduce, and find a grinder that is capable of grinding that material. Whether it is industrial waste or municipal waste, there is a commercial food waste disposer and trash grinder that is right for the job, just make sure you are choosing one that is capable of doing the job you desire.

2. How do you want those waste materials processed?

Another important aspect to consider is what you want the end-result to be after the waste is put through the food waste grinder. Do you want primarily to have a more compact amount of waste to dispose of?  Is odor a concern?  Do you want a grinder with a compactor integrated so that it squeezes out all excess water, and the solid dry waste is deposited into a garbage can?  The options are endless.

3. What levels of capacity are you looking for in a food waste grinder?

Depending on where the grinder is going to be used, the desired capacity of a food waste grinder may be different for different needs.  Whether you’re looking to put one in for a college food service kitchen or a large food producer, there is a food waste grinder out there that will have the capacity you are looking for.

4. How will the food waste get to the food waste grinder?

Is someone going to be manually feeding the food waste into the grinder?  Will the food waste grinder be attached to an internal pipe and so automatically get fed waste to process?  Understanding where exactly the grinder is needed and whether or not you will have someone managing/monitoring it, is very important.

5. Who will be in charge of maintenance?

Once you procure a food waste grinder you will be responsible for keeping the machine functioning and properly maintained.  Not all food waste grinders require someone manually operating them, however, most food waste grinders do require some level of maintenance on a regular basis.  So, before you buy a food waste grinder, make sure you either have someone on-site who can manage the machine, or you pick a provider who offers on-going maintenance assistance.

As you may know, the first ever dual-shafted wastewater grinder was invented by JCWE founders Joseph and Woodie Chambers back in 1973 (eventually it was given the name Muffin Monster).  Wastewater grinding technologies have only improved over the past few decades, making it so there is a wastewater grinder for almost every waste reducing need of today.
