High-Efficiency Centrifugal Mill
High-performance Pin Mill provides a precise and cost-effective solution for grinding, sizing, and homogenizing friable materials. Designed for versatility, it delivers a narrow particle size distribution—ranging from coarse to 400 mesh—completely eliminating the need for traditional screens, hammers, or knives.
The material enters through a central inlet and is accelerated by high-speed centrifugal force. It passes through a series of alternating stationary and rotating pins, undergoing thousands of high-impact collisions. By simply adjusting the rotor speed (up to 5000+ RPM), operators can achieve exact particle sizes without changing any physical parts.
Technical Versatility
- Broad Application: Ideal for food, chemicals, pharmaceuticals, minerals, and agricultural products.
- Precision Control: Adjustable disc speeds allow for seamless transitions between coarse grinding and fine powdering.
- Cooler Operation: Minimal material retention and constant airflow prevent heat buildup, protecting heat-sensitive products.
- Easy Sanitary Design: Features smooth interior surfaces and a hinged vertical disc for easy access, total gravity discharge, and rapid cleaning. Designed for industries that require frequent wash-downs and strict sanitation protocols.
- Superior Accuracy: Achieve tight, consistent particle size ranges without the hassle of screens.
- Efficiency & Speed: High-capacity throughput in a compact, space-saving footprint.
- Low Maintenance: A simple, rugged design with no complex moving parts like hammers or rolls ensures near-zero maintenance.
- Ultimate Flexibility: One machine can handle everything from de-lumping agglomerates to fine pulverizing.
Specifications
- Materials: Available in Carbon Steel and Stainless Steel (Industrial or Sanitary/Pharma standards).
- Sizes: Disc diameters available in 8, 18, 24, and 34 inches.
- Power: High-capacity motors ranging from 5 to 125 hp.
Why Choose Pin Mill?
Pin Mill stands out as a versatile and cost-effective solution for industries requiring precise particle size control without the complexity of traditional milling equipment. By eliminating screens, hammers, and knives, it minimizes mechanical wear and simplifies the entire production process. Whether you are processing food-grade flour or specialized chemicals, the ability to adjust output from coarse to 400 mesh via simple speed control ensures that a single unit can adapt to your evolving production needs with ease.
Beyond performance, its design prioritizes operational efficiency and hygiene. The compact footprint houses a high-capacity system that remains cool during operation, protecting the integrity of your heat-sensitive materials. Maintenance is virtually non-existent thanks to the rugged, simplified internal structure, while the hinged disc design allows for rapid cleaning and total gravity discharge. Choosing Pin Mill means investing in a reliable, low-maintenance asset that ensures consistent product quality and maximum uptime for your facility.
Pins on the Chamber
Centrifugal force drives material through hundreds of pins, resulting in thousands of impacts as it moves outward toward the chamber walls—ensuring a uniform and controlled grind.
Pin Mill Model CIM-24-SS, Pin & Disc Assembly, Vertical Design
High-precision rotating impactor pin and disc assembly for both fine and ultra-fine particle reduction, offering excellent de-agglomeration performance when operated at lower speeds. Features a 24-inch (610 mm) rotating disc supported by heavy-duty, oversized pillow-block bearings. Powered by a 30 to 60 hp (22 to 45 kw) motor and a high-performance V-belt drive, this system delivers significantly higher throughput per kilowatt than traditional mills using screens, hammers, or knives. To minimize downtime, the mill housing is vertically oriented with a hinged outer disc.
PinMill Model CIM-24-MS, Open-Chamber: Hinged Housing & Optional Davit Arms
Pin Mill with 24 in. (61 cm) discs. The open-chamber view reveals specialized abrasion-resistant impactor pins, engineered to withstand wear while maintaining peak milling performance. The mill’s vertical housing is designed with a convenient hinge system, allowing it to swing open for quick inspections and rapid cleaning of all product-contact surfaces. For even greater ease of maintenance, offers an optional davit arm for the housing and a second davit arm for the removable rotor disc, making part handling effortless.
Pin Mill Model CIM-24-MS, Closed Chamber: Infeed Elbow & Support Arm
Pin Mill in closed position. This 24-inch (61 cm) disc model utilizes a cantilevered support arm and a 90-degree infeed elbow, engineered for streamlined material intake and structural integrity during high-capacity operation.
PinMill Model CIM-18-SS, Compact Direct-Drive
This 18-inch (457 mm) model provides precise sizing and conditioning for dry solids, capable of reaching fine 400 mesh powder. By utilizing an efficient direct drive system, this unit cuts the required installation space in half compared to belt-driven machines, making it the perfect choice for facilities where floor space is at a premium.
Pin Mill Model CIM-18-S316, Pharmaceutical-Grade
Designed for the most stringent hygiene requirements, the pharmaceutical-grade this model features both removable inner and outer discs. This dual-removable design provides unobstructed access to all disc surfaces and the mill housing, ensuring comprehensive cleaning and effortless sanitization. Equipped with a wash-down motor and sanitary fittings, it allows for fast sanitizing cycles and minimal downtime.
