A PVC granulation project should begin with the formulation, incoming material form and required pellet. Rigid and flexible compounds, virgin and returned material, filler level, additives and heat sensitivity can lead to different feeding, mixing, venting, pelletizing and cooling requirements.
RUNNING MACHINE asks buyers to define the material workflow before selecting a machine configuration. The proposal should state what arrives at the line, which preparation steps already exist and what pellet condition is required for the next process.
Typical equipment scope
- Material mixing, cooling, dosing and feeding equipment when required
- Extruder selected for the defined PVC compound and process
- Venting, filtration or melt-handling components when applicable
- Pelletizing system selected after pellet form and formulation are confirmed
- Cooling, conveying and screening equipment
- Collection and storage equipment
- Optional dust control and material-return auxiliaries
The final equipment scope is project-specific. A quotation should distinguish included machinery, optional items, wear parts, controls and buyer-supplied utilities.
Information needed for a proposal
- Rigid or flexible PVC application
- Complete formulation information available, including filler and additives
- Virgin, dry-blend, regrind or other incoming material form
- Required pellet shape and accepted sample when available
- Color range and changeover expectations
- Required feeding, venting, filtration, cooling and screening steps
- Target production rate
- Next process that will use the pellets
- Dust collection and material-return plan
- Voltage, cooling-water, compressed-air and workshop conditions
Frequently asked questions
Which pelletizing method should be selected?
The method should follow the formulation, material temperature behavior, required pellet form and cooling plan. Share the compound and accepted pellet sample so the process can be reviewed.
Can one line make rigid and flexible PVC compounds?
Do not assume identical equipment and settings. Provide both formulations, production mix and changeover requirements so shared and product-specific components can be identified.
Can returned material be processed?
Describe its source, particle size, cleanliness, moisture, previous processing history and intended proportion. The preparation route and quality controls must be discussed before it is included in the equipment scope.
