V3.3 New Version Shredder machines are designed towards a modular format, allowing customers to convert - de-assemble or re-assemble as simply as a small IKEA flat pack process.

Motor is not included.
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. 40:1 will produce 310nm and a comfortable 70RPM.  if you choose a unmatched combination you will face underpower or overpower towards RPM/Torque, KW hour.

Motor to gearbox ratio must be a set balance to achieve the project requirement.

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, jamming, limited shredding requirements on your build. its always a good choice to know the thicker material can be shredded by the correct power combination used.

Motor speeds can also be at 1440 purchased single phase. 2.2KW and gearbox ratio 30:1 will give an excellent torque of 328nm and a comfortable  48-50 RPM. Calculation of build reliability/operation is an important factor to consider in any project.

Coli reçu un peu en retard par rapport aux délais annoncés. Ensuite les éléments (rondelles, rivets...) se trouvaient dans le carton en vrac sans emballage, des rivets étaient tordus donc inutilisables. Une fois monté le broyage est quand même compliqué, c'est dur, vite épuisant, il y a beaucoup de frottements entre les lames et la manivelle fournie n'est pas de bonne qualité. Elle se tord facilement dès que ça bloque, elle aurait méritée d'être vraiment plus solide. Dans l'ensemble je suis déçu de mon achat même si l'ensemble est solide, je pense à mettre un moteur car ce n'est pas envisageable de continuer manuellement.

(translated by the Bazar Team)
Package received a little late compared to the announced deadlines. Then the elements (washers, rivets...) were in the loose box without packaging, the rivets were twisted and therefore unusable. Once mounted, the grinding is still complicated, it's hard, quickly exhausting, there is a lot of friction between the blades and the crank provided is not of good quality. It twists easily as soon as it blocks, it would have deserved to be really stronger. Overall I'm disappointed with my purchase even if the whole thing is solid, I'm thinking of putting in a motor because it's not possible to continue manually.
Excellent services. Very fast response.
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
