Plastic Bottle Recycling Machine: PET Bottle Shredder and Crusher
From baled post-consumer bottles to bottling-line rejects, our PET bottle recycling machines crush PET into clean, washable flakes. Crushers and grinders built by Raj Electricals since 1985, from 35 kg/hr to 1,200 kg/hr.
Why a PET Recycling Plant Crushes Bottles into Flakes
PET bottles are among the most collected plastics in India: kabadiwala networks, MRFs and bottling plants all generate them. The problem is never supply. It is bulk. Empty bottles are almost all air, so a full truck of loose bottles carries very little actual material. That is why bottles move as compressed bales, and why a PET recycling plant’s economics only start working once those bales are broken open and the bottles are crushed into dense flakes that are cheap to store, transport and feed into a washing line.
The second problem is contamination. BOPP and PVC labels, HDPE/PP caps and ring seals, leftover liquid and adhesive all travel with the bottle. Flake buyers (washing lines, recycled polyester fibre (PSF) plants and rPET pelletizers) pay on flake purity and colour separation, and they discount or reject contaminated lots. With EPR obligations under the Plastic Waste Management Rules now forcing brand owners to buy recycled PET content, demand for clean flake is rising, but only processors who control crushing quality capture that margin. Sending baled bottles onward unprocessed means giving that margin away to someone else.
Choosing a Bottle Grinder Machine for PET
PET bottles do not need the ripping torque of a heavy dual shaft shredder. They need a sharp, high-speed cutting chamber with a screen that controls flake size. That is why our standard recommendation is a blade-type bottle grinder machine: bottles are fed in whole, rotating blades cut them against fixed blades, and only flakes small enough to pass the screen leave the chamber. The standard screen is 12–15 mm and can be made to your requirement, so you decide the flake size your buyer wants.
Machine selection comes down to bottle size and daily volume. The RE12CB grinder with blower handles 500 ml to 1 litre bottles at 45 kg/hr, right-sized for a bottling plant destroying rejects or a small recycler. The RE16 plastic bottle machine takes bottles and jars up to 10 litres at 150–250 kg/hr. For flake production at scale, the RE series runs up to the RE40, with a 40″ × 40″ throat and 1,000–1,200 kg/hr. Blower-fitted models convey flakes straight out of the chamber into collection bags, keeping the cutting chamber clear and the floor clean. Machines are built in MS as standard, and SS grade and export-voltage motors are available on request.
PET Bottle Shredding Process, From Bale to Flake
- De-baling & sorting Bales are broken open, PVC bottles, glass and foreign objects are removed by hand-sorting
- Metal check Stray metal is screened out, coins and caps with foil break blades and void flake lots
- Crushing to flakes Bottles are fed whole, the rotor cuts them against a screen, 12–15 mm as standard or made to your requirement
- Blower discharge Flakes are conveyed pneumatically out of the chamber into collection bags
- Washing & float separation Downstream, labels and PO caps float off while clean PET flake sinks
- Drying & dispatch Washed flake is dried and packed for pelletizing, fibre or sheet plants

Applications and Industries for PET Bottle Recycling
PET bottle recycling runs from bale to flake. Bales, loose bottles in sacks, line rejects and preforms go in. Flakes sized by the screen come out, blown into bags on the blower models, ready for washing lines, rPET pelletizers, polyester fibre plants and sheet makers.

Frequently Asked Questions
What is the best machine to crush plastic bottles?
It depends on your bottles and your volume, so we answer by fit rather than with one name. For PET bottles the right tool is a blade-type bottle grinder machine with a screen, not a heavy dual shaft shredder, because the screen sets the flake size your buyer pays for. The RE12CB grinder with blower suits bottles up to 1 litre at 45 kg/hr. The RE16 takes mixed bottles and jars up to 10 litres at 150–250 kg/hr. For flake production by the tonne, the RE series runs up to the RE40 at 1,000–1,200 kg/hr. Work out your kilograms per day, divide by the hours you will run, and size with some headroom, because throughput varies with feeding speed, material and bulk density. A trial on your own bottles settles it, and our machine selection guide walks through the sizing.
How much does a bottle crusher cost?
Every machine is quoted to the job, so we do not publish prices. The price of a plastic bottle crusher machine depends on the model and its capacity, the bottles and jars you feed, the motor rating, MS or SS construction, and options such as blower discharge into bags and the screen size. Tell us your bottle sizes and daily volume and we will recommend a model and send a quotation. Our guide to what drives machine cost explains each factor.
Why crush PET bottles into flakes instead of selling baled bottles?
Bulk and value. Baled bottles sell as scrap. Clean, sorted flake is what washing lines, rPET pelletizers and polyester fibre plants buy, because the transport bulk and part of the contamination are already gone. Crushing also raises bulk density, so the same truck carries far more saleable material.
Do I need to remove caps and labels before feeding bottles into the crusher?
Not one by one. That would kill throughput. The usual practice is to hand-sort out PVC bottles, metal and glass before feeding (metal breaks blades), then crush the bottles with caps and labels on. Downstream, a float-sink wash tank separates them: HDPE and PP caps and label fragments float, and PET flake sinks. The separated caps can go through an HDPE grinder machine and be sold as regrind of their own. If your buyer wants unwashed flake, expect a price discount for the cap and label fraction. That is normal trade practice.
What flake size do PET washing lines need, and can the machine produce it?
The flake size is set by the screen in the cutting chamber. Our standard screen is 12–15 mm, and we make it to your buyer’s specification on request. Most washing lines in India work comfortably with flake in this range. Because the screen is replaceable, you can change flake size later without changing the machine. See the Plastic Grinder page for screen and model details.
How much does a plastic bottle maker machine cost?
A plastic bottle maker machine is a blow molding machine, which is not part of our range, so we cannot quote one. We build what works beside it: grinders for the reject bottles, preforms and start-up scrap a blow molding line produces, so the material is reused or sold instead of dumped. The price of one of our grinders depends on the model, the capacity you need, the motor rating and options such as blower discharge. Our blow molding scrap grinder page covers that duty.
Can I see the machine crush my own bottles before buying?
Yes, and we encourage it. Bring a sample lot of your actual bottles, baled or loose, and we will run a trial so you can check flake size, throughput and output quality yourself before committing. Contact us to book a trial slot.
What maintenance does a bottle crusher need, and what about blades?
The routine items are blade sharpening and lubrication. Blades are re-sharpened periodically, and how often depends on your running hours and how clean the material is (sand and grit dull blades faster). The RE8 to RE25 carry 3 rotating and 2 fixed blades, the RE30 6 and 4, and the RE40 9 and 6. Every machine comes with a 1 year manufacturer warranty against manufacturing defects, plus lifetime service and spares support.
