Overview
The document provides technical specifications and features of the Wynveen Hammer Mill Type GHM, designed for grinding raw materials in the feed industry, including aqua feed and pet food production. It highlights the mill's innovative design, safety features, and performance capabilities.

Specifications
The hammer mill is available in three models: GHM-750B(A), GHM-1000B(A), and GHM-1250B(A), with motor power ranging from 132 to 400 kW. The screen surface area varies from 1.2 to 2.0 m², and the number of hammers ranges from 90 to 132. The capacity for maize and barley processing is specified, with weights ranging from 2700 to 4500 kg.

Design and Features
The mill features adjustable breaker plates that create an asymmetric grinding chamber, enhancing impact forces and material flow. It supports dual rotation directions and includes a robust construction with anti-vibration shock absorbers. The rotor is carefully balanced and can accommodate 6 or 8 beater rows.

Performance
The asymmetric grinding chamber design increases capacity by 20-30% compared to conventional mills. It maintains product temperature, minimizing moisture loss. The mill can grind high-fat materials to 100% <800µ with capacities up to 18 t/h. Specific power consumption details for different materials are provided.

Safety and Options
Safety features include large inspection doors with electromechanical interlocks and temperature sensors on main bearings to prevent explosion risks, complying with Atex 137 guidelines. Optional features include automatic screen changing, explosion detection devices, and frequency conversion for motor speed control.

Feeding System
The feeding roll ensures even material flow, driven by a 1.5 kW geared motor. It includes a stone trap and a strong magnet for removing heavy trash and iron particles. A multiple dosing screw conveyor is available for materials with high fat content.

Conclusion
The Wynveen Hammer Mill Type GHM is a versatile and efficient solution for feed processing, offering enhanced capacity, safety, and adaptability to various materials and conditions.
