Why Do Grinders Fail?

How do grinders work?
Grinders break cannabis flowers by 2 rotational pins / Teeth to different directions - like scissors. As this operation performs the flower is being broken into little pieces, it is important to understand that grinders should not crush the buds, if they do so, they will clog very fast and loose their terpene profile.

The pins/ Teeth are located on plates, which their side wall is used as the bearing flange. after using the grinder for some time, depending on the grinders quality, the friction surface between the 2 chambers starts to collect pollen.

once the grinder is packed with pollen, it is becoming sticky and clogged. grinders than starts to fail, they become very difficult to rotate. as you probably have seen your friends applying force to rotate the grinder you should know that little particles that we cannot see with our bare eyes are being mixed into our smokeable medicine. this happens with every time of grinder out there. the safest to use grinders are made of stainless steel, however – they are not perfect. Friction derived from the same material resulting wear equally on the 2 parts, so having a stainless steel grinder doesn't make it safe to use. it will still wear out. 

Why Do Grinders Fail?

Grinders functionality is subjected to friction and over time – bits/flacks of the raw material will mix with the grounded weed. This leads to contamination which growers take a lot of efforts to avoid on growing stages.

Friction Explained

Upon rotation, there is some friction built between the grinders parts. watch this video to see how that looks like inside of the grinder.

GRINDER BUILT WRONGLY

Most grinder manufacturers got it wrong. Starting from positioning the magnets on the wrong side which ends up by the flower stuck on the bottom of the grinder part. 

The magnet is positioned in the correct place. why is that? As placing a bud to grind up, usually there is not enough space to hold a bud at it whole, so the natural habit is to press the top part of the bottom part – as a result the magnets will not meat each other and you will end up with a little piece of bud stuck in the middle of the bottom part. This is happening as there is little to almost none grinding happening in the middle section of the grinder, most of the grinding will perform on the wider sides of the grinder as the blades doing their work spreading the bud to consumable medicine.

 

BOTTOM OR TOP?

Top and bottom parts of grinders distinguished by the simple principle of the bottom part should be smaller than the top part. It is actually more a matter of female and male parts. As the male part should be considered as the bottom part which the female part slides over it. This kind of orientation helps to increase the grinders longevity, more about it below. 

This grinder and it is very disoriented. it functions as bottom part but will not secure the cannabis from sticking to the inner side wall which functions as the bushing. This kind of construction leads to fast wearing and enhances the risks of metal shavings ending mixed with grounded medicine.

 

GRINDERS -  PRECISION DEMANDING PRODUCTS

Grinder work out as a bearing, they rotate and friction is generated by the moving parts. To have a proper grind the teeth must go all the way to the other section to minimize dead spots. To proper;y do so, a machining precision is required which means that higher costs are added to production. When not done right the teeth will contact the other part bottom surface and degrade upon rotation. the picture below shows clear signs of wear
