Superior choice of single phase 3kw motor with 50:1 wormgear/gearbox producing 56RPM shaft rotation and an excellent torque gearbox ratio for this shredder combination of 380+nm. if you choose a unmatched combination you may face underpower or overpower RPM or torque which may not be enough torque or may even incur damage. KW hour, motor speed to gearbox ration must be a set balance to achieve the project requirement by purchased shredder machine. Please discuss the required setup for your project if you feel it may help.

As an example - 2.2kw motor 2800 with 30.1 ratio will produce high RPM at 94 and low NM of about 169. This minimum combination choice may give a lot of stop start, limited shredding thickness requirements on your build.its always a good pattern to know the thicker material can be shredded by the correct power combination used. Motor speeds can also be low 1440 purchased single phase. calcuation of operation must be a good combination for best outcome. Message if you need assistance.

A fantastic product machined to exacting levels of accuracy. Great communication and assistance throughout the process. Arrived well packaged and in great time. Would definitely recommend to buy from the team.
Very Quick to respond to questions; knowledgeable about shredder construction and parts sourcing; Order shipped quickly and delivered in perfect condition. They are a very good asset to the PP community.

I highly recommend!
very Happy with my purchase, very reasonable price, quick shipping. Seller answered all the questions I had.
Purchased a shredder body and duct from alana and reading shredding , very professional , kept up to date every step of the way , very hassle free. Would definitely recommend and buy again , goods nicely made and dispatched. thank you

oh and on time !!!
I purchased a shredder kit from Reading Shredder a few weeks back. I had no experience building a shredder, first time bazaar buyer and was a little skeptic about being able to gather all the right parts. Alana was great from the start, he answered all my questions pertaining about the kit and he gave me a bunch of building recommendation (motor type, coupling, etc)

He kept the me informed through out the whole process, from production schedule to shipping and receiving. The package had no delays with customs. No hidden fees, it was a pretty straightforward transaction.

The Shredder kit is great, built solid, it has all the parts. I’m currently in the middle of wiring it together. Hope to share and post final build.

I would recommend and will buy again from RS without a doubt. The customer service and open communication is priceless, it kept my anxiety down and has encouraged me to purchase from the PS bazar in the future.

Thank you Alana & Reading Shredder
This was my first experience buying off the Bazar and it was such a good one. They were so friendly and patient with the whole process. Shipping to Canada wasn't an issue at all! I would have no hesitation ordering from this seller again.
Very happy with my all stainless steel 3.1 shredder. Exactly what we wanted with quick, efficient, helpful and high-quality work.
Much appreciated!
