The PNMF series is a disc-type PVC film pulverizer designed for flexible and low-hardness plastic materials. Unlike the PNMP turbo-blade series used for rigid PVC pipe and profiles, the PNMF uses a centrifugal disc mechanism: material is fed through the centre of a fixed grinding disc and carried outward through the grinding gap by centrifugal force, producing fine powder in the 20–120 mesh range at 30–600 kg/h depending on model.

Important for PVC film processing: raw PVC film cannot be fed directly into this machine. Film must first be processed through an agglomerator machine to compact loose film into densified granules before pulverising. This two-step process is standard for all flexible PVC film recycling applications.

PVC Film Pulverizer Application Areas:

The PNMF series handles flexible and medium-hardness thermoplastics that are unsuitable for turbo-blade pulverisers. Primary materials include agglomerated PVC film, PVC artificial leather, and soft PVC sheet offcuts. The machine is also used for PE, PP, PS, ABS, EVA, PET, and nylon powder production where a consistent 20–120 mesh output is required for compounding, masterbatch, or rotomoulding applications. The PNMF-300 and PNMF-400 are commonly used for small-batch or R&D production; the PNMF-600 and PNMF-800 are specified for continuous industrial-scale powder output.

PVC Film Pulverizer Description：

For PVC film grinding, the film needs to be treated with an agglomerator machine first and then grind.

PNMF series is available with disc diameters from 300 to 800 mm. These plastic pulverizing machines are high-speed, precision grinders for the processing of medium-hard, impact-resistant and friable materials. The material to be pulverized is introduced through the center of a vertically fixed grinding disc which is mounted concentrically with an identical high-speed rotating disc. Centrifugal force carries the material through the grinding area and the resulting powder is collected with a blower and cyclone system. Depending on the application the machines can be equipped with one-piece grinding discs or grinding segments.

The plastic pulverizing machine is mainly composed of an electric motor, disc-type blade, feeding fan, vibrating sieve, dust removing system, etc.
According to the customer’s needs, you can choose some accessories, such as a converter, vacuum loader, screw loader, magnetic net, metal separator, chiller, pulse dust collector, metering and weighing packaging machine, etc.

PVC Film Pulverizer Components:

Vibratory Feeding Even feed rate into the disc centre prevents localised wear on the grinding disc. Built-in magnetic element captures metal contaminants in the feed stream before they reach the grinding surfaces.	Pulverizer Disc Fixed disc uses double-layer construction with water-cooled cavity; rotating disc uses atomised spray cooling. Both cooling methods run simultaneously to maintain stable processing temperature across the full grinding area — critical for heat-sensitive materials like PVC film compound.
Whole Body Pulverizer Blade One-piece disc blade for standard applications. Customisable tooth geometry to match specific material hardness and target mesh size. Standard configuration for PNMF-300 through PNMF-500.	Segment Pulverizer Blade Split-segment blade available for PNMF-600 and PNMF-800. Individual segments can be resharpened up to 4–5 times before replacement, reducing consumable cost per tonne of output compared to whole-body blade designs.
Temperature Control Automated cooling system: thermostat monitors disc temperature and triggers solenoid valve to adjust cooling water flow. If temperature exceeds the set threshold, the feed switch pauses material input until the disc returns to operating range — protecting both the material and the grinding surfaces.	Vibrating Screen Real-time in-line classification. On-spec powder discharges directly; oversized particles return to the disc automatically. Screen mesh is interchangeable for different target fineness.
Bags Type Dust Catcher Standard dust collection option. Compact footprint, lower cost. Suitable for most single-unit installations. Upgrade to pulse dust collector available for higher-volume or enclosed workshop environments.	Intelligent Control PLC panel with adjustable feed rate, disc speed, and cooling parameters. Fault detection halts the machine on overload or temperature exceedance and displays an error code for rapid diagnosis.

PVC Film Pulverizer Technical Features:

1. The new disc design is of high quality, and strong resistance and the life of this grinding disc is double the ordinary ones.
2. The newly designed professional bearings is with a high rotation rate. At the same time using only one drive motor ensures efficient grinding crash, which greatly saves the time of machine operation and engineering control.
3. Easy installation and maintenance, just open the door to clean up.
4. The whole milling process is sealed, without dust leakage.
5. Full automatic design, automatically feeding, discharging and sorting.
6. Grinding gap adjustment is simple, just use the feeler gauge and adjusting bolts can be fine-tuning.
7. The mill uses the water and wind double cooling system, Prevent the bearing and other parts from overheating.
8. Well-known brand accessories, such as SKF bearings and Siemens motors, can work for a long time, saving the trouble of changing accessories frequently.
9. With a wide range of optional accessories, professional solutions can be developed based on the customer’s budget and processing requirements.

Frequently Asked Questions

Why does PVC film need to be agglomerated before pulverising?

Raw PVC film is too light and flexible to feed consistently into a disc pulveriser — it tends to bridge at the feed inlet and wrap around moving parts rather than passing through the grinding gap. Agglomeration compacts loose film into dense, free-flowing granules (typically 3–8 mm) that feed evenly into the PNMF disc centre by gravity and vibration. Skipping this step results in irregular powder output and risks disc damage.

What is the difference between the PNMF and PNMP series?

The PNMP series uses a turbo-type blade disc and is designed for rigid PVC materials such as pipe, profiles, and hard sheet (15–100 mesh, 100–900 kg/h). The PNMF series uses a centrifugal flat disc mechanism and is designed for flexible or medium-hardness materials including agglomerated PVC film, soft sheet, and a broad range of thermoplastics (20–120 mesh, 30–600 kg/h). The two series are not interchangeable for their respective primary materials.

Can the PNMF process materials other than PVC film?

Yes. The PNMF handles a wide range of medium-hardness thermoplastics: PE, HDPE, PP, PS, ABS, EVA, PET, and nylon are all within the machine’s operating range. For each material, disc gap and screen mesh are adjusted to match the target powder specification. Highly abrasive or very hard materials (e.g. rigid UPVC pipe) are better suited to the PNMP series.
