Shredder v2.2 Philippines Model

27/11/2017 at 03:41

So we over here at Precious Plastics Philippines, have started development on a shredder 2.2

Namely because the standard model just is not enough capacity, and certain design elements of the original are a bit higher cost than the local budget.

So We have come up with a shredder double the size.

Basically the STEP file was imported into CAD, and the number of teeth was doubled.

The second thing, is that the gear motors used can be quite expensive, and if we are to make a lot of them, there is a lack of a standard used gear motor. This is fine for one off custom work. However frankly, we got a LOT of plastic to process and we need a LOT of machines.

So in that aspect, we are developing the shredder to use a local standard 6.5hp gasoline engine. This engine is very common here brand new and costs between $125USD to $200USD depending on the brand.

This enables a more portable machine that can be used on site for waste collection drives. Basically its collect and shred right on the beach, or at a municipal waste point.

The Philippines also in some areas has a lack of good electrical service. Especially in remote islands. Basically electric service is pretty much everywhere, but it is hard to get the high current everywhere. We viewed a local made shredder based on a China design. It had a 32amp current draw and startup is double that. Based on personal experiences, this is just not feasible everywhere.

Yes it will work in Metro Manila, and cities, but the farther you get away from those areas, the more difficult it gets.

So we present to you the CAD rendering for shredder v2.2

Unfortunately I am unable to export in STEP files, only dxf, rsdoc, and sketchup. If someone has access to Spaceclaim CAD, we can convert the file to solid models and then it will be good for use in Solidworks, Inventor, 360 etc.

Wow a gaspowered shedder, sounds like a beast!
6,5HP should definitly do it, maybe you even want to reinforce some parts 🙂
feel free to keep us updated

Awesome idea man, it’s a big improve in the power. Question: What about the consumption in general? I mean, the idea is to know which is cheaper in an industrial application, gas or electricity.

Keep us updated,
José

gasoline engines are better for the Philippines market.

Here is why:

Beach cleanups on site can be accomplished easier and less transport costs.

Electric service in remote islands is often times generator powered.

In many areas the electric service is erratic, especially places whose sole power source is hydro in the dry months.

The costs for a gasoline engine is aprox 130USD vs a electric motor, gear box, wiring etc.

The large gasoline engine can be run at a near idle speed so the fuel consumption is not great.

My own experience in the Philippines, I converted a 3hp craftsman air compressor to gasoline engine and it ran fine on low throttle.

Regarding files there only needs to have these parts modified, and double the number of the inside bits.

I would upload to thingiverse, but seeing as they deleted all my previous uploads for this project. I am reluctant to use them again

I will upload to my dropbox and share the files there
https://www.dropbox.com/sh/ecy22db7s633srt/AACrW15yaaPSmXRk-PxqWPgEa?dl=0

The CAD file is in DesignSpark Mechanical CAD format, but it should be simple enough to use. It is also free software

I have not yet uploaded the new hopper files

The blade parts just make 2 sets.

Has anyone made progress on a gas-powered shredder? I’m starting to look into doing this in Guatemala.
