Rotors, Teeth, & Screens
Our commitment to “Perfect In One Pass” solutions extends through every level of our company, from dedicated R & D to a responsive customer support team that keeps your operation running with knowledgeable advice and the right teeth and screens for the results you need.
Our rotor, tooth, and screen designs offer practical solutions for processing a wide range of materials with low operating costs and consistent uptime.
Screen Installation System
Each of our grinders and chip processors allows fast, convenient screen changes using only the simple tools provided with the machine. Rotochopper customers who have operated other grinders quickly come to appreciate the simplicity and reliability of our patented screen change system. The ability to quickly change screens limits downtime and enhances versatility, allowing operators to easily swap screens to meet different end product size specs.
Where most screen installation systems use bolts or other fasteners to hold screens in place, our unique system utilizes cam arms to quickly secure screens in operating position, minimizing operator stress and downtime. Integrated shear protection limits damage from severe rotor impacts.
This exclusive system has served Rotochopper owners with reliability and convenience for over ten years.
Screens
For any application with demanding end product specs, the right screen is absolutely critical. We offer a wide selection of screens to make sure you get the right match for your raw materials and finished product needs.
In each of our grinders and chip processors, the size and relationship of the screen to the rotor are all designed for single-pass particle size consistency. The way the feedstock transitions from the feed conveyor to the grinding chamber is another critical factor in the finished product quality that sets our grinders apart from the competition. Learn more about our unique infeed transition system.
Square-hole screens (standard) offer particle size control for a wide range of raw materials.
Round-hole screens help achieve even greater particle uniformity than standard square-hole screens. Because round-hole screens also help produce fewer jagged edges, they are often used for animal bedding, playground cushion, and other products with tight specifications.
Baffled screens help produce more uniform particle lengths. Baffled screens feature curved louvers welded into place behind the screen openings to inhibit over-length particles from exiting the screen. Available with square or round holes.
Graduated screens prevent over-grinding for some materials and allow better passage of tramp objects. The holes in graduated screens widen from the bottom of the screen to the top, allowing ground particles (and un-grindable objects like steel) to exit the screen more easily as the material moves toward the top of the screen. Graduated screens are also sometimes used in applications for which particle size control is not critical.
Radial cut screens (for shingle grinders only) reduce the resistance of material exiting the screen holes to allow properly sized particles to quickly pass from the grinding chamber, decreasing wear and increasing throughput rates.
Rotors & Teeth
Each of our horizontal grinders is available with multiple tooth and rotor styles to maximize efficiency, versatility, particle size control, and wear life for different raw materials. Our specialized grinding equipment, the CP-118 Chip Processor and RG-1 Asphalt Shingle Grinder, utilize rotors designed specifically for their unique applications.
