Hey community

@rbagg066, yes it will be the next download kit.

We work on it, like you can see 🙂

For assembly it, with all the part, take around 2 hours without the frame and hopper.
We will start the test the 29 July.

So, what we need:

It needs higher torque: it get stuck with cd cases and big HDPE bottles. We want to keep the same power (around 3kW). That means we have to lower the speed to get higher torque. So we need a higher ratio for the gearbox. New blades: Flakes are too big. More teeth and less thickness Hard to clean: The flakes can accumulate in many places of the shredder The gripping is not good: sometimes the shredder can’t catch the plastics. Easy to build: Keep a design easy to assembly with part easy to find.

In the double shaft shredders, the size of the flakes is determined by the number of the teeth and thier respectively width. The new design of the blades is mainly focused to get small flakes and to have a good gripping as well. So we design a shaft with 13 teeths/blade (small flakes) and another one with only 6 teeths (good gripping)

We made also something very easy to build and assembly, we have also include the gears inside the box for more safety

And we have also increase the output and decrease the speed of the motor for answer to the stucks problems

For the specs :

Size of blades: 6 x 130

Shredding dimension: 240 x 300

Motor:

Power: 2,2 Kw

Output speed: 19 RPM

Nominal torque: 1000 Nm

So we make this new design:

TADAAAAAM!

Hey community :

For this shredder we have a 3 phases motor with these specs:

Power: 3kW

Output speed: 65rpm

Nominal torque: 440 Nm

Gearbox Ratio: 1:21,43

After building the first V4 shredder, we have test it during 2 weeks with differents plastics :

PP : Sheets, DVD cases, buckets…

HDPE : Sheets, Bottles, Buckets

PS : Sheets

we have drawn these conclusions:

The most big problem we can see during this test is the thickness of the blades, 10 mm make big flakes and the motor is not enough powerful for shred everything. Also the design is not easy to build.

Good, it looks very interseting!
The differents tests does with the doubles axes make the plastics chips to thicks. That because the blades are not crossing enought, like the Fig 1 on the picture. We need to cross more, with larger diameter blades and smaller diameter washer, change the the space between the 2 shafts like the Fig 2 AND change the thickness of the blades, for 6 or 8 VS 10 for the prototype. In this case, it will be a little more long for shred plastic, maybe we will limited on the plastic thickness, but the flakes will be, for sure, smaller.

Guys, let me know your opinion 😉

For the final version, if we choose this version, the idea it’s make something easy to build, with the minimum weld, screws… for give the possibility to build it everywhere with the minimum tools. if you are some idea about it, let we know here 🙂

Hey community,

We have start the test of the double axis shredder, we will try different sheet with different thicknesses and compare the result with the single shaft.

We have decided to try with cutting blades to test the capacity of the shredder to grip the sheet.

Then, we will check if the flakes are enought small for be injected or compressed without re-shred. We will check the good point and bad point of the double axis (price, easy to build, powerfull, speed…), if we can do much better with flat blades and we will compared all that with the single shaft.

@doctom22

Mon moteur est un 1,5 kw triphasé ou j’ai mis un condensateur pour le passer en monophasé, tu perds énormément de puissance mais ça marche bien quand même. Je tourne à 55 tours min pour 220 Nm en sortie, et finalement, il pèse 40 kg 😀

Je l’ai trouvé chez un spécialiste Alpes motorisation.

My engine is a 1.5 kw three phase where I put a capacitor to switch to single phase, you lose a lot of power but it works well anyway. I turn at 55 rpm for 220 Nm out, and finally, it weighs 40 kg: D

I found it at a specialist Alpes motorisation.

@zin27

Coté moteur c’est le point ou je bloque, du coup je fais appel à une société spécialisé mais j’en ai pour 400 à 600 euros selon le modèle. donc je pense qu’une bétonnière c’est pas mal oui mais je ne m’y connais pas assez sur le sujet!

@anfa

Send me a message on my profile, i will send you my number

@zin27

It’s better for find people to help you and have some advantage!! 😀 I have make almost everything by myself, it was looooong but i have arrived. Some part was make by a firm near my place.

L’asso c’est mieux pour trouver du monde et avoir des avantages, comme un local a dispo…J’ai presque tout fais moi même, c’était pas simple, mais j’ai fais faire qq pièces par une boite près de chez moi.

@nanasama

Commence par le shredder c’est le plus simple et le moins coûteux! après tu verras pour la suite, essai de trouver du monde, et monte une asso ou un truc en commun pour réduire les frais!!

Hey salut à tous,

mon shredder est fini mais je galère du coté élec, autant la mécanique ça a été simple mais le triphasé c’est pas mon truc.

Avez vous un schéma électrique ou une photo pour le branchement des contacteurs, sachant que j’ai un interrupteur 3 pins pour tourner dans les 2 sens.
Contacteur : https://www.aliexpress.com/item/660V-20A-50Hz-3-Phase-220-230V-Coil-Motor-1NO-AC-Contactor-CJX2-0910/32708867567.html

Je cherche aussi un tube de 34 x 26 x 4 impossible à trouver par chez moi, si vous avez des idées 😉

Merci

ENGLISH

I look an electric plan or picture for connect contactor with a 3 pins interuptor for the both direction at the motor.

Hey @louis-b, good to see your work, good job. I have a question, where are you find the drill diameter 26? And the tube 34×26? or maybe you have change dimension?

Thank you 😉
