- After some years, finally I made my first tutorial video, after many question and comment in my previous video about design and production of plastic shredder.
This is general step for design a shredder, and there's some detail step to make it perfect, but for this step it's basic that can help you in design process. - วิทยาศาสตร์และเทคโนโลยี
Very good explanation, Thank you.
Osm..👏👏
Thanks for your suggestion
أحسنت واصل وفقك الله.
tnx dear
hi, excelent video, I have been looking for something as complete as yours, again, good job, I am in Panama, if you are visiting lets get together for a cup of tea and some shredder talk.
Thank u bro I'm watch ur video in slow motion awesome thanks a lot
Thank you 🙏🙏
Thanks for your video, it helped me a lot in my project.
can you share how to calculate the stress for the blade? not use the program
Proud of you Bro! :) Keep it up!
Haha thank you sista
Very useful
Thanks a lot
Hi, thanks so much for sharing your knowledge! I am working on final student project and we are going to make a shredding machine for PLA 3D fail material. I will use your functions for referencing. Could you give us the reference, such as: name of work, author, data pulishing and publisher. Thanks!
Dear brothers
thanks for your information about plastic shredder .
please make another video for palm oil production machine
Thanks for watching, i'll make it when i have a chance :D
Hello. Can you show mee the calculation for the torque drive shaft (108 Nm). I don't understand what you have done. Thanks!
how did you calculate the RPM needed for the shredding ?
hi why did you multiply the rpm to 0.00014 to get Hp??
Very nice video bro. I want to know if shear shredder will work for green tea leaves and I can't find shear strength of green tea leaves for force calculation on the blade design.
please do reply....
Thank you for watching bro, I never seen about mechanical properties of leaves, I did som search and maybe this will help you www.sciencedirect.com/science/article/pii/S025462990800241X.
but if you want to make sure, just do some trial with your workpiece, tensile test. Thank you !
Dang, i wish i had paid more attention to my physics class lol
Hi!, which books or text do you recommend me for the design of the cutting system? and the blades
I use basic book like fundamental of mechanic L kraige
Hi thanks so much for sharing your idea. how to gate the revolution of the shaft at first that mean N1 how to gate ? which type of belt is used please shear the total calculation part or design part
You can got revolution from motor spec and reduce ratio of your pulley set. I used A type. (It depend on total transmitt torque)
Sir it is really worth to have a complete idea of the same, but can you please share us the CAD DESIGN
Hello sir we're sorry but my old CAD data isnt available
How you calculate the required force to crush a plastic?
Hi do you have a link to the STL files? I wanted to make this out of plastic with a 3D printer for a project of mine.
Hi, I'm sorry I dont have that link
Brother Mohammed Mashaa Allah you’re a very experienced designer, i was wondering about the capacity of your machine, is it determined by the multiplication of the overlapping shear areas of the blade (side area), by the average linear velocity of these overlapping blades (2*PI*60/Radius), and by the density of the target material should this shredder put up with, and finally by the number of blade-to-blade interface (i.e. if you have 16 blades you do have 15 interface) ?
Hello Brother Ahmad, Thank you for watching.
About your question, the answer is yes, it determine by:
1. Total overlapping area of blade. My intersect area isn't 15. Bcs the blade angle configuration was 3. So it will overlapping every 3 set blade.
2. Total cutting edge, mine is 4.
3. Rotation each blade.
Density of material only for determine input method.
Thank you.
Muhammad Sigit Wicaksono That’s great, I will be very pleased if you can send me the capacity calculations.
Thanks in advance my estimated brother.

can you tell me what will be the resultant thickness of the shredded pieces according to the sizes of the blades that you chose?
In blade design I assume blade thickness become cutting area for shredded plastic, in case i want about 10mm widht shredded plastic.
Nice 👍 video. My blad just hitting each other what should I do?
Thanks for watching, I got is also when first assembly, you have adjust those blade position by spacher thickness. Or add chamfer in blade side ( i saw another shredder with loose between each blade. There's a friction from each blade)
Hello
I am from India. What is your advise for production capacity like 300 kg per hour . Can we use 5 or 7 HP motor with your this specification ?
Hello, just in my opinion... to determine the exact performancr you have to calculate it first, at least general calculation for motor power
Hey bro where did you get the 0.00014 value on cumputing the horsepower?
Hello, it was coefficient for convert kW to hp
I want to make Styrofoam shredder which kind of shredder should i use.
Styrofoam is soft material and I think it will be a granular result if you use grinder mechanism, but you can use shear shredder too, it was a universal mechanism for any kind of workpiece.
Hi, how did you calculate the shaft diameter?
did you did that project ?
hi
please help me
how can I calculate the clearance between blades?
Just choose base on your workpiece, thinner clearance more diffucult to assy
Hello, Can you explain more about the torque on the drive shaft? why did it increase from 54 Nm to 108 Nm? So the other 54 Nm belongs to which axis? Hope you reply. Thank you
Hello, its because prime mover on drive shaft. It drive two shaft that each shaft has 54Nm load.
Iam planning to build a shredder for hdpe or pvc pipes please guide me where to get the parts im based in dubai
Im sorry but I have no idea cs I didnt stay in Dubai
Hello! How to kind of chipper shredder can u get me link of its??? thanks
It's slightly rare but I got it from my library
Untuk pembebanan blade menggunakan tegangan normal ultimate, kenapa tidak menggunakan tegangan geser material? Terima Kasih.
Penggunaan nilai beban material trgantung case, jika workpiece tercacah secara tarik maka gunakan normal ultimate, dan ktika trcacah dengan metode potong (shear) maka gunakan shear stress max. In case shredder utk plastik trdapat 2 pmbebanan. Disini digunakan yg trtinggi.
What is the cost that you required for this machine?
Hey sir! Do you have the file of the design ? Let me know if you dont have it. Thanks a lot.
Brother 8 blade cut ? From where you got it??
Did you mean 4 blade cut? One blade has 4 cutting teeth. And 2 blade on the 2 shaft cut in same time
bro can you please let me know on which software you design that shredder machine?
I used solidworks bro
can you tell me.How can we get 108 Nm?It is 2 shaft or what?
Its total Torque from 2 shaft
Share some information abt how you reduced rpm in step 1 and 2... How you did it? Calculation i need to know..
I explained it on 04:59. It used 2 step pulley reduction
Kalau untuk mesin pencacah tipe reel yang pisaunya seperti balok perhitungannya bagaimana ya? kalau tidak salah tipe mesinnya tipe reel
Untuk perhitungan pada pisau hanya berbeda di jarak terjauh saja (perhitungan momen)
hello! can i get cad model of this shredder? i want to use it for my project.
Hello, we're sorry but i cannot share thr cad model for now
Bro I need calculation for organic waste shredder
how u calculated the area of the blade edge?or u take it as assumption 1mm?
Blade width 10mm, and edge sharp assumption 0.1mm. Assume edge area 1mm2
@@muhammadsigit973 thanks bro it's my final year project this year I need some help in calculation can u give me ur email
@@muhammadsigit973 and brother other question is that how we can find the diameter of both pulley if we don't have the rpm of that pulley. Means how u select this diameter of pulley
@@moeez-ul-haq8159 1. Determine final rpm in blade that you need, calculate ratio between your motor and your blade.
2. Choose the diameter pulley that available in the market depends on your ratio.
@@muhammadsigit973 thanks bro 😍
Sir i am bandula in sri lanka i want this machine how to get it details and price and the dell
I'm sorry for now I'm not sell it
why did you chose 4 edges ? what happen if i use 2 edge ?
Its okay, I think it will affect the cutting result many edge = smoother result
at 3:00, you have added 54 two times. But isn't the torque of two gears are different ?
For stress calculation I assume two shaft cutting in the same time.
Hello. force 44.82 mpa where did you get it to calculate?
Hi you can get it from mechanical properties of plastic
can you tell me how many MPA is required to destroy paper? I can't find any documentation about that. thank you very much
how to calculate the speed of the shaft of plastic shredder machine
Determine the target capacity, then you can calculate the shaft speed
kindly share the total design on my email as i need 1 table top to shared plastic runner from auto components like nylon, Styron, delrin, and tpu.
Can you explain how u get stress?
It come from max stress of workpiece in cutting area.
How to determine blade cuts
Blade cut determine based on target capacity (kg/hour) depend on rotation setting
How to make cloth shredder nachine
I think that will be a similar concept, but adjust in blade gap and load.
good day sir, is it possible to obtain a copy of the SolidWorks design from you ?
Hello sir, we're sorry my old CAD data isnt available, I'm making new one
How did you decide to have 1mm² edge?
Widht of blade x height in blade tip (assume it was sharp with 1mm height)
@@muhammadsigit973 is the width of the blade 1mm?
@@muhammadsigit973 also how did you get 4.48MPa. what if only one shaft rotates against a stationary blade system? pls can you design that one, i follow you...
so so sorry but going through your calculation for cutting force value I don't think is correct. 44.82Mpa x 1mm^2 =44.8N not 4.88N. Please look into this, thanks
Also, how did you calculate your area?
I confirm 1MPa = 1 000 000N/m², 1 000 000mm² = 1m² thus 1MPa•mm² = 1N
Great, but a pulley is problematic. Most shredders just have robust gear wheels, right ?
Yes off course, I think that gear design need a high safety factor 😅
Gan, ini biaya paling besar habis buat manufaktur bagian apanya?
Kalo case sy dulu waktu bikin blade.. sama case tempat holder shaft.
Sir, do you have the complete calculations for this machine? If so, could you share it through email? If not, it's okay, and thank you for reading this.
how did you get 44.84 Mpa
It from plastic strength that work on blade edge..
Can you put us a diagram in the PDF file
Is it really 4.48 N?
I guess that there is conversion error
We're sorry.. that miss type there it should be 44.82N. Thank you
Whay stress 44.44.82mpa..how clculat
It from standard mechanical properties for PET plastic
Brother Muhammad, may I know, how do we design the shredder blade? Like shape and number of teeth. Which type of blade that is the best? Any source that I can refer to?
Hi brother, about blade shape design until now I found no detail explanation about this..
Commonly design is 2 or 3 teeth in one blade. I try to made 4 teeth but cannot compare yet. It need some research. But so far I think it's affect to cutting time and capacity.
Thank you.
@@muhammadsigit973 Thank you so much for the reply brother. I have another questions. For simulation of the cutting blade, the max stress is 1.5 MPa. Is it acceptable? Because the tensile strength of the plastic is 44.82 MPa. Second question, how do you get the value of 6.75 Nm torque? I tried to recalculate and the answer is 0.675 Nm.
Hi brother, about stress simulation.. that's true material strength is 44.82 MPa, but the force in cutting edge it should 44.82 N (I have a miss conversion in beginning of the video).
That force give the stress in blade max in 1.5MPa, different shape will give diferent amount, you can try in your own.
About the result, because of miss conversion in the beginning you can follow the step, but rechecked your own calculation. Thank you
@@muhammadsigit973 Understood. Thank you so much brother for the explanation 🙏🏻🙇🏻♂️
@@AfifMuslih it means 44.82Mpa is not the tensile strength of plastic but it is the tensile strength of mild steel???
bang bantuin saya bang.saya mahu buat project machine shredder ini.saya student dari malaysia🇲🇾
Hello, jika ada pertanyaan detail bisa comment di kolom komentar ya. Thank you
Link to your calculations please
Sorry, the calculation link is not available for now
What is called as blade cut sir
You took as 8.. don't know how
1 shaft has 15 blades ,
each blade has 15 teeth,
assumed force applied on 3 teeth
what is the blade cut for this?
Blade in each shaft sir, cutting blade for each blade is 4
Brother how much price?
Cost production is about USD 800
gan boleh share file pdf skripsinya? hehe lumayan buat referensi tugas akhir saya kalau boleh
Paling hanya jurnal gan.
