Zhiyi Machine is a plastic recycling machine manufacturer based in Chang'an Town, Dongguan, China. The company builds three lines of size reduction equipment — plastic shredders (ZSS, ZDS, ZDS-HD), plastic crushers (ZPC, ZPC-HD) and plastic pulverizers (MPD for PVC, MF for PE) — covering the full reduction path from whole pipe and bulky parts at 40–100 mm, through regrind at 6–20 mm, down to powder at 10–150 mesh.
Seven series are in production. Motor power runs from 11 kW on the smallest crusher to 160 kW on the largest single-shaft shredder, with throughput from roughly 50 kg/h on a small pulverizer to 2,000 kg/h on a ZSS-2000 shredder. Machines are configured to the feed stock: rotor type, screen mesh and blade material are selected against the material being processed rather than sold as fixed models.
Three machine classes, each covering a different stage of size reduction. Together they take plastic from whole parts through to powder.
Primary reduction of bulky plastic — pipe, drums, pallets, purgings and bales — down to a chip that can be conveyed, washed or fed to a crusher. Single-shaft ZSS machines use a hydraulic ram to push material into the rotor; double-shaft ZDS and ZDS-HD machines pull it in with counter-rotating hook blades.
Secondary reduction to a uniform regrind that can be washed, pelletised or fed straight back to a moulding machine. The ZPC runs a flat paddle rotor at 580–650 RPM against interchangeable screens; the ZPC-HD handles thick-wall and high-volume scrap at 45–132 kW.
Fine grinding of pre-crushed regrind into powder for rotomoulding, PVC compounding, masterbatch and WPC/SPC flooring. Both are vertical disc mills and both need feed of 10 mm or less, so a crusher stage sits in front of them. MPD covers PVC at 60–150 mesh; MF covers PE at 10–120 mesh.
A recycling line rarely needs all three machines. Pick the last stage that matches your target output size, then size the stages in front of it.
Whole pipe, drums, pallets, bales and bulky scrap reduced to a conveyable chip. Output is set by the screen, not by the rotor.
ZSS · ZDS · ZDS-HD
Uniform regrind ready for washing, pelletising or direct return to a moulding machine. Screen changes move the target size.
ZPC · ZPC-HD
Powder for rotomoulding, PVC compounding, masterbatch and flooring. Requires crusher regrind of 10 mm or less as feed.
MPD · MF
Zhiyi Machine is a manufacturer specializing in plastic recycling machinery, covering research, development and production of plastic shredder machines, plastic crusher machines and plastic pulverizers.
The range is built as a process chain rather than as standalone machines. A shredder is sized against the largest piece it has to accept, a crusher against the regrind size the downstream process needs, and a pulverizer against the mesh the end product requires. Because the stages are specified together, a line can be quoted against a material and a throughput rather than assembled from whatever is in stock.

Feed stock form matters as much as the polymer. These five rows cover the enquiries we see most often; the full ten-row matrix is on the applications page.
| Material / input | Typical form | Process chain | Recommended series | Typical output |
|---|---|---|---|---|
| PE / PP / PVC pipe, profile, sheet | Whole sections, offcuts | Shred → Crush | ZSS / ZDS → ZPC | 6-20 mm regrind |
| PVC pipe, profile, skirting | 6-20 mm regrind | Pulverize | MPD | 60-150 mesh powder |
| PE granules and flakes for rotomoulding | 10 mm or less | Pulverize | MF | 10-120 mesh powder |
| Film, woven sack, jumbo bag (FIBC) | Rolls, bales | Shred → Crush | ZSS / ZDS → ZPC | 6-20 mm regrind |
| Pallets, drums, IBC containers, bumpers | Bulky, high volume | Shred | ZDS-HD | 40-150 mm chips |
Choosing the right recycling equipment manufacturer is essential for stable production and long-term operation. Zhiyi Machine provides reliable machines with professional engineering support.
Shredders, crushers and pulverizers are built by the same workshop, so a line can be specified as a chain — each stage sized against the next rather than bought separately.
Screen mesh, rotor and blade set are selected against the material: 40–100 mm screens on shredders, 6–20 mm interchangeable screens on crushers, 10–150 mesh on pulverizers.
Cutting and grinding components are specified by material and duty: SKD-11 flat paddle blades on the ZPC crusher range, high-resistance grinding discs on the MPD pulverizer.

Our machines can process various plastics including PE, PP, PVC, HDPE and industrial plastic waste.
A plastic shredder is mainly used for primary size reduction of large plastic waste, while a crusher further reduces plastic materials into smaller particles for recycling processing.
Most lines run two or three stages. Shredding reduces whole parts, pipe and bales to 40-100 mm. Crushing takes that flake down to a uniform 6-20 mm regrind. Pulverizing grinds regrind of 10 mm or less into powder between 10 and 150 mesh.
A plant that only needs regrind stops after crushing; a plant feeding rotomoulding or PVC compounding adds the pulverizing stage.
A plastic pulverizer machine is used to grind plastic materials into fine powder for recycling and reuse. It is widely applied in processing PE, PP, PVC, ABS and other thermoplastic materials.
Plastic pulverizers are commonly used for producing plastic powder in applications such as rotational molding, PVC pipe recycling, WPC/SPC flooring production, masterbatch manufacturing and other plastic processing industries.
By reducing plastic scraps into uniform fine particles, a plastic pulverizer machine helps manufacturers improve material utilization, reduce waste and produce high-quality recycled plastic powder.
Yes. We design customized recycling solutions based on material type, capacity requirements and final product requirements.
Four details are enough for a first recommendation: the plastic type, the physical form of the feed stock, the required throughput in kilograms per hour, and the target output size.
Feed stock form matters as much as the polymer, because a shredder that handles six-metre pipe is sized differently from one handling baled film.
Yes. We provide technical support and complete service solutions for customers worldwide.
The cost of a plastic recycling machine depends on several factors, including the type of machine, processing capacity, material type, and customized configuration requirements.
For example, a plastic shredder, plastic crusher, or plastic pulverizer may have different prices based on the required output, motor power, blade design, and production requirements. A complete recycling solution with multiple machines will also vary depending on the recycling process and final product requirements.
At Zhiyi Machine, we provide customized plastic recycling solutions according to your materials and production needs. Contact us with your plastic material type, required capacity and application details, and our engineers will recommend the most suitable machine configuration and provide a quotation.
