Pilot Plant Pulverizer 5-7.5 HP
As a complete system mounted on a portable stand, our versatile laboratory-to-production scale pulverizer allows you to validate your process and begin small-scale manufacturing with a single, reliable machine.
It enables your business to overcome:
- Process validation risk: Our solution uses the same proven impact milling principles as our large-scale industrial machines. This design maintains consistent particle characteristics as volume increases, simplifying the validation process and promoting a predictable path to full production.
- Difficulties handling different or diverse materials: We have built our overhead feed screw small pulverizer for real-world feedstock, allowing your team to handle larger, bulkier materials up to 2 inches. It also supports cryogenic compatibility for effectively milling heat-sensitive or tough polymers.
- Missing throughput control: The standard variable speed drive on the feed screw provides direct control over material flow and residence time, allowing your crew to optimize grind quality and production rates for different materials.
- Fixed-asset inefficiency: As a caster-mounted system with integrated motors and starters, you can easily move the Model A between development labs and production lines, maximizing its utility and your return on investment.
How Our Production Pulverizer Works
See how our portable industrial pulverizer, 5-7.5 HP, operates as a seamless system in your daily operations:
- Controlled feed: The 1-¾-inch screw feeds clay, pharmaceutical ingredients, recycling waste or other materials into the chamber while the variable speed drive precisely manages its rate to prevent surges and facilitate consistency.
- High-energy reduction: Inside the chamber, the robust 8-inch rotor assembly impacts the material with high kinetic energy, reducing material size.
- Consistent classification: Only particles that meet the size specification can pass through the 44-square-inch screen for collection.
- Steady discharge: The pulverizer discharges the finished product, ready for the next manufacturing stage, from blending to packaging.
Industries That Benefit From the Model A
The power and adaptability of our pulverizer make it a critical asset for creating pilot batches, validating processes and running continuous, small-scale manufacturing lines.
Examples of industries that use this solution include:
- Specialty chemicals and pharmaceuticals: Produce pilot-scale batches of active pharmaceutical ingredients and specialty chemicals and seamlessly transition from R&D to clinical trials.
- Nutraceuticals and food production: Our small continuous production pulverizer produces the larger batches of functional food ingredients, supplements or spices needed for consumer trials and initial product launches.
- Advanced polymers and minerals: The robust design and optional overhead feed screw are ideal for handling challenging feedstock as you prepare for full-scale mineral processing or polymer manufacturing.
