Ultra Centrifugal Mill High Speed Laboratory Grinder for Fibrous and Brittle Sample Preparation

Product Overview

This high-speed ultra centrifugal mill represents a pinnacle in laboratory sample preparation, specifically engineered to handle a diverse spectrum of materials from soft and elastic to hard, brittle, and fibrous. By utilizing a sophisticated two-stage grinding process—combining initial impact with secondary shearing—this equipment delivers exceptional fineness in remarkably short processing times. The core value of the system lies in its ability to produce highly homogeneous samples while preserving the chemical and physical integrity of the material, a critical requirement for precise analytical results in material science.

The equipment is a versatile workhorse across numerous industrial and research sectors, including agriculture, environmental monitoring, RoHS testing, and chemical engineering. Whether processing plant stems for C.H.N determination, coal for thermal measurements, or plastic waste for heavy metal analysis, this unit provides the consistency needed for high-throughput laboratory environments. Its capability to perform both dry and wet grinding further expands its utility, making it an essential tool for laboratories focused on nutrition, pharmaceuticals, and polymer science.

Built for demanding industrial conditions, the system emphasizes operational reliability and user safety. The robust motor, protected by advanced sealing and overload safeguards, ensures long-term performance even when processing difficult, abrasive samples. Laboratory procurement teams can rely on the equipment's precision-engineered rotor-sieve system to deliver repeatable particle size distributions, minimizing user error and maximizing lab productivity. The combination of high-speed centrifugal force and durable construction positions this unit as a premium investment for facilities requiring uncompromising sample preparation standards.

Key Features

• Advanced Two-Stage Grinding Mechanism: This system utilizes a unique combination of high-speed impact and secondary shearing. Samples enter the grinding chamber and are first subjected to a massive impact force from the rotating knife, followed by intense shearing and friction between the rotor and the ring sieve, ensuring rapid reduction to the desired fineness.
• Variable Speed Control: The unit offers a wide adjustable speed range from 6,000 to 18,000 RPM. This allows operators to fine-tune the peripheral speed (up to 94.2 m/s) to match the specific fracture behavior of different materials, preventing thermal degradation of heat-sensitive samples.
• Precision Engineering and Fineness: Capable of achieving a final fineness of less than 40μm, the equipment relies on interchangeable ring sieves. This flexibility ensures that the particle size distribution can be strictly controlled for various analytical requirements, from simple feed analysis to complex RoHS compliance testing.
• Integrated Aerodynamic Cooling: A specially designed air passage maintains a constant airflow through the grinding chamber. This cooling effect is vital for protecting the motor and ensuring that the sample nature remains unchanged during high-energy processing, particularly for temperature-sensitive organic materials.
• Industrial-Grade Sealing Technology: To ensure longevity and prevent mechanical failure, a double-layer wear-proof seal ring is installed between the grinding chamber and the driving motor. This barrier prevents fine dust and abrasive particles from compromising the internal motor components.
• Smart Touch Control Interface: The modern touch-sensitive panel provides a convenient and intuitive interface for setting parameters. This digital control system enhances repeatability across different shifts and operators, ensuring that grinding protocols are followed precisely.
• Dual-Layer Safety Protection: The system incorporates both electronic and mechanical locks to protect the operator. The grinding chamber cannot be opened while the rotor is in motion, and the unit will not start unless the housing is fully secured, meeting stringent laboratory safety standards.
• Anti-Splashing Hopper Design: The feeding hopper is engineered to prevent feedstock from blocking or splashing back during the high-speed operation. This design also contributes to noise reduction, maintaining a more comfortable working environment in the laboratory.
• Automatic Feed Compatibility: For laboratories requiring high homogeneity and hands-free operation, the unit can be equipped with an optional automatic feeding device. This prevents overloading and ensures a steady, controlled material flow for the most consistent grinding results possible.
