Plastic recyclers need a crusher that runs all shift, handles mixed bottles and drums, and delivers flakes of even size. The SM-Series PET Bottle Recycling Crusher Machine from Mooge is built for that job. It crushes PET bottles, HDPE and PP containers, plastic drums and rigid scrap into uniform flakes at 300 to 3,000 kg/h.
This guide is for importers, distributors and plant managers who compare suppliers and check specifications before sending an inquiry. It explains how the machine works, what each main component does, which screen and blade to choose, and what to ask any supplier. All technical data comes from Mooge's product page. Our team can confirm final details for your project.

What Is an SM-Series PET Bottle Crusher Machine and How Does It Work?

 
The SM-Series is a rotor-and-screen crusher. It is a core machine in plastic washing lines and in plastic recycling and granulation lines. Plastic processing plants and waste plastic recycling plants use it to turn hard waste plastic and production scrap into thin, uniform flakes. Small flakes are easier to wash, melt and granulate, so the crusher helps lower your downstream cost.

The crushing process, step by step

1. Bottles enter the hopper by conveyor belt or by hand.
2. The motor drives the rotor at high speed.
3. Rotor blades pass the fixed blades on the frame. The gap between them shears the plastic into small pieces.
4. Flakes that reach the screen mesh size fall through the screen and leave the machine.
5. Larger pieces stay in the chamber and keep cutting until they meet the required size.

Where the crusher fits in your line

Most buyers place the crusher before the washing section. Mooge also builds a complete PET bottle washing line that removes labels, caps, glue and contaminants to produce clean PET flakes. Tell us your full process, and we can match the crusher to the rest of the line.

Technical Specifications: SM-600 to SM-1500 Capacity and Power

The series has five models. Choose by your real hourly input and the type of material you crush.

Model	Rotor Blades	Fixed Blades	Screen	Power (kW)	Capacity
SM-600	8	4	14 mm	45	300 kg/h
SM-800	8	4	14 mm	55	500 kg/h
SM-1000	8	4	14 mm	75	800-1000 kg/h
SM-1200	12	4	14 mm	90	1500-2000 kg/h
SM-1500	12	4	14 mm	110	2000-3000 kg/h

Capacity is input capacity. Actual output depends on the material, bottle condition, screen size and feeding method. Send us your target kg/h and material, and we will recommend a model. We suggest sizing for your normal daily throughput, not your occasional peak.

Manual Feeding or Conveyor Belt: Which Feeding Method Suits Your Plant?

The crusher supports two feeding methods. Pick the one that fits your volume and labor plan.

• Conveyor belt feeding: An inclined belt conveyor feeds material automatically and continuously. It saves labor and suits plants with steady daily volume.
• Manual feeding: Workers load material straight into the hopper. This works well for small batches and flexible production.

If your material arrives as bulky or oversized items, add a plastic shredder machine before the crusher. Give us a photo or sample of your raw material, and we will advise on the best feeding setup.

Semi-Auto Metal Detector: Protecting Your Crusher Blades from Metal Contamination

Metal pieces in a bottle bale can chip blades and damage the screen. A semi-auto metal detector is an optional addition that helps you avoid this.
The detector sits on the feeding conveyor. When it finds metal, it stops the belt and sounds an alarm. The machine runs again only after workers remove the metal. Detection sensitivity is 8 mm or larger for ferrous metal and 10 mm or larger for non-ferrous metal. If your raw material comes from mixed post-consumer sources, we recommend adding this option.

Main Motor Options: WEG and Innomotics (Siemens) for Stable, Energy-Efficient Crushing

The main motor drives the rotor, so its quality decides how stable the machine runs. Mooge offers WEG, INNOMOTICS (a Siemens brand) and other well-known domestic brands. The motors use all-copper windings for smooth output and strong power. A radiator hood helps the motor stay cool during long shifts, and the high-hardness shaft is built for durability.
The cutter design also targets high capacity with low power consumption. State your preferred motor brand, voltage and frequency when you request a quotation, so the offer matches your local power supply.

Inside Rotor and Cutter: Claw-Type Blade Holder for High-Efficiency PET Crushing

The inside rotor and cutter do the real work. The rotor is forged from 40Cr alloy steel, which balances hardness with toughness for long, heavy-duty operation. The claw-type blade holder makes crushing more efficient and makes blade removal and replacement easier.
The cross-type cutter structure uses quenched 45# steel to deliver high capacity at low power use. The bearing housing sits outside the crushing chamber. This design keeps dust and fines away from the bearings, extends bearing life and keeps the lubrication system clean.

Blades: SKD-11, D2 or DC53 Material, Sharpened 20-25 Times

Blade cost is one of your largest running costs, so ask every supplier about blade material and service life. The standard blades on the SM-Series use SKD-11 steel from Japan. You can also request D2, DC53 or Hardox.

• The blade tips are wider, so you can sharpen each blade 20 to 25 times.
• Sharpening instead of replacing saves money over the machine's life.
• Blade material can match your plastic type and contamination level.

When you place an order, consider adding a spare blade set. It keeps your line running while you sharpen the worn set.

Screen Mesh Size Guide: 14-16 mm for PET Bottles, 16-20 mm for HDPE and PP

 
The screen mesh sets the final flake size. It is made from 10 mm thick steel for long service life, and a flange makes installation, removal and replacement simple.

• PET bottles or cans: use a 14-16 mm screen.
• HDPE, PP and ABS bottles or cans: use a 16-20 mm screen.
• Other sizes: smaller or larger screens are available on request.

A smaller screen usually gives finer flakes but can reduce throughput. Choose the size your washing and pelletizing stages need, and tell us before production so we can fit the right screen.

Auto Opening of Hopper: Faster Blade Changes and Easier Maintenance

Blade changes and cleaning cause most of the downtime on a crusher. The auto opening of hopper reduces that time. A screw motor opens the chamber, so workers do not need to remove bolts by hand. You can also choose a hydraulic system, which cuts manual work further.
With the chamber open, your team can quickly replace the rotor blades, fixed blades and bottom screen mesh. This is a practical feature if you run several shifts or crush abrasive material.

Electrical Control Panel: Siemens PLC and ABB Inverter with Auto-Reverse Overload Protection

The electrical control panel uses a Siemens PLC, Schneider contactors and buttons, and an ABB frequency converter. These are familiar brands, so your local electricians can source spare parts and service the panel easily.
The panel also protects the machine. If the motor current rises too high, the main motor stops and reverses automatically to clear jammed material. This reduces the risk of motor damage and saves your operators from manual clearing.

Screw Loader and Packing Frame: Collecting PET Flakes Efficiently

After crushing, you can discharge flakes directly and collect them by hand. For a cleaner and faster setup, we suggest a screw loader with a double packing frame behind the crusher. Jumbo bags sit underneath, so flakes go straight into bags with little handling. If the crusher feeds a washing line, the screw loader can move flakes onward instead.

Materials You Can Crush: PET Bottles, HDPE Drums, PP Containers and Rigid Plastic Scrap

The machine handles a wide range of hard and hollow plastic waste:

• PET bottles and cans
• Plastic drums and buckets
• ABS, PP and HDPE bottles
• Hollow containers
• Hard rigid plastic and plastic scrap from production

Many buyers combine the crusher with a complete PE/PP/PS/ABS rigid recycling line to turn this material into clean flakes ready for pelletizing. Tell us your material type, size and condition, and we will check the setup together.

Wet vs Dry Crushing: When to Choose a Stainless Steel (316/316L) Machine

Standard crushing runs dry. If your process crushes with water, parts that touch water are made of stainless steel. We can also supply 316 or 316L stainless steel if you need higher corrosion resistance. The 40 mm chamber also uses a rubber seal to prevent water leakage.
Decide this at the quotation stage. Changing materials later costs more and delays your project.

Why Choose the SM-Series: 40 mm Solid Steel Chamber and Externally Mounted Bearings

Buyers who need a dependable SM-Series PET Bottle Recycling Crusher Machine should compare build quality, not only price. These points matter on the SM-Series:

• A 40 mm solid steel chamber with a rubber seal to prevent water leaking.
• Bearing housings mounted outside the chamber, away from dust and fines.
• An 8 mm steel upper hopper with a cover, so flakes do not fly out during crushing.
• A 10 mm steel screen and replaceable, resharpenable blades.
• A screw-motor or hydraulic opening system for easy maintenance.

Supplier checklist for importers and distributors

• Confirm the model, capacity, screen size and blade material in writing.
• Ask which motor, PLC and inverter brands the quotation includes.
• Request videos of the machine running with your type of material.
• Agree on voltage, frequency and spare parts before payment.
• Ask about packing, shipping terms and installation support.
