Check Out These Areas If You Grinder Is Humming

If you have ever worked with a brand new grinder, you must have observed that they are very silent during operation. That should ideally be the condition of the grinder throughout its lifespan. But due to the wearing off of the wear parts, the machine will start making some noises with time.  It is common to hear a relatively used grinding machine humming.  However, some operators think that it is a common thing but it is not. Humming is a problem that must be fixed for that piece of equipment work properly. The question is what could be the problem if your grinder is humming? Well, these area areas check and Fix:

Cutting Wear parts

The humming of the grinder is an indication it is being overworked or its efficiency is compromised. One of the first areas to check are the cutting wear parts. That includes the grinder teeth which does the actual cutting work. In most cases, the condition of the teeth is usually the main problem. The grinder teeth could be dull or broken thus making it difficult for the grinder to work. That is the case, make sure that you have sharpened the teeth or replaced them if necessary. Loose grinder teeth is another issue that causes poor grinding and thus the humming of the machine. Therefore, ensure that all teeth are tightened regularly.

Check Transmission Belts

Another key grinder wear part that you must check if your machine is humming is the belt connecting the engine and the wheel cutter. The belt is the main part that transfers power from the engine to the teeth. If 100 percent of the power is not transmitted to the cutting disk, then the machine will be forced to work extra harder. That will result in the humming of the machine. Worn out belt also lowers the efficiency of the machine which in turn causes results in humming. Therefore, make sure that you have replaced the belt with a new one if the condition is wanting.

Type of wood

What type of wood are you grinding? Can your machine handle the task? Are you overworking the machine? These are questions you must provide answers to, especially if the two mentioned above are not the problem. Check out if the grinder is designed hard or soft wood. That can be seen from the type of teeth installed and the capacity of the grinder engine. If the machine capacity is below what is required of the task, then it will definitely start humming. The solution is to bring a bigger grinding machine.
