Overview

The document presents detailed technical information about the Pulsotronic-Anlagentechnik GmbH metal separator, specifically the KR series with models KR100 to KR300, equipped with M-Pulse2pro or Digital2 electronics. These separators are designed for high-precision metal detection in free-falling bulk materials, suitable for various industries including food processing.

Specific Characteristics

• Maintenance-free mechanical design
• External operating panel with 5 m cable (optionally up to 10 m)
• Large transmission ports up to 300 mm diameter for high throughput
• Robust pneumatic-driven ejection mechanics (optional)
• Available with or without ejection mechanics
• Protection class IP65 ensuring dust and water resistance
• Stainless steel housing suitable for hygienic environments
• Supporting frame can be integrated into existing constructions

Technical Data

Mechanical and Material Specifications:

• Material of ejection unit and base frame: Stainless steel
• Protection tube material: POM (other materials available)

Operating Conditions:

• Storage temperature: -10 to 60°C
• Operating temperature: 0 to 50°C
• Protection class: IP65
• Pneumatic connection: 4–6 bar, filtered, free of water and oil, with self-sealing coupling NW 7.2

Performance:

• Throughput ranges from 12,000 l/h (KR100) up to 100,000 l/h (KR300), measured with PET granulate (2-3 mm grain size)
• Bulk material must be free-flowing

Sensitivity (minimum detectable metal size in mm):

Note: Sensitivity depends on environmental conditions, vibrations, and conductive properties of the test material.

Functional Description

The metal detector sensor coil is positioned at the upper part of the separator. Upon detecting metal, the electronics trigger the ejection flap to divert contaminated material through a bad outlet, ensuring safe removal from the product stream. The ejection function can be monitored depending on the electronics used. The pneumatic-driven ejection mechanism is robust and durable, with optional wear-resistant versions for abrasive products.

The control panel can be mounted remotely up to 10 meters away for ease of operation in difficult-to-access locations. A pressure control device can monitor the correct function of the pneumatic system.

Delivery Program and Accessories

All KR series devices are delivered without ejection mechanics by default. Ejection mechanics are available separately for all sizes. Optional accessories include:

• Pneumatic guard
• Ejector guard (indicates malfunction)
• Compressed air cooling (60–100°C)
• Wear-resistant product pipes (glass)
• Antistatic/food-grade product pipes
• External operating panel with 10 m cable
• Various ejection flaps (dustproof, wear-resistant, different angles)
• Connecting kits for installation with or without ejector

Dimensions

The document provides detailed dimensional data for each KR model (KR100 to KR300), including length (Dimension A), width (B), height (C), and other relevant measurements (D, E, F). Dimensions increase with model size, supporting throughput capacity.

Standards and Notes

• Protection class IP65 compliant
• Materials and manufacturing comply with ISO standards (ISO 16016, ISO 2768 - m)
• Delivery times depend on timely confirmation of order documents (within 2 working days)

Summary

The Pulsotronic KR metal separator series offers high-precision metal detection for free-falling bulk materials with robust stainless steel construction and flexible installation options. Its modular design allows customization with or without ejection mechanics and various accessories to suit different industrial applications, including food processing. The system ensures reliable metal detection with adjustable sensitivity and durable pneumatic ejection, supported by remote operation capabilities and comprehensive accessory options.
