Overview

The document presents technical specifications and features of the MBW series of "FLEXFLO" Micro-Batch Feeders manufactured by WAM S.p.A. These feeders are designed for precise micro-batching of dry materials with facilitated flow and self-cleaning capabilities.

Product Description

• MBW Micro-Batch Feeders: Monoblock units featuring a non-stick inlet hopper surface to facilitate material flow.
• Self-Cleaning: Assisted pneumatically via compressed air injection to enhance hopper wall movement and prevent material sticking.
• Screw (Dosierwendel) in SINT®EX: Made from non-stick material with a tapered shape, integrated with the center pipe. The screw has a constant flexing between flight and shaft to avoid material adhesion.
• Flexible Hopper Walls: Made from plastic casting with flexible walls to optimize material discharge, further improved by interval-controlled pneumatic actuation.

Key Features

• Screws with Different Pitches: Available to accommodate various material flow requirements.
• Casing Material: Made from SINT®AL, suitable for dry food products.
• Round Inlet Hopper with Agitator: Ensures consistent feeding and prevents material bridging.
• Minimum Clearance: Tight clearance between screw flight and outlet pipe to ensure precise dosing.
• Offset Outlet Pipe: Positioned off-center to optimize material discharge.
• Standard Seal: Incorporates multiple rings for effective sealing, including integrated labyrinth ring seals.

Technical Data and Performance

• Feed Rates at 1 RPM: Examples include MBW 015 at 0.05 dm³/h, MBW 042 at 0.64 dm³/h, and MBW 073 at 7.40 dm³/h.
• Internal Hopper Design: Walls have varied inclinations and geometries to facilitate extraction of difficult or poorly flowing materials.
• Compressed Air Cavity: Enables pneumatic activation to assist self-cleaning and maintain consistent filling of the screw.

Options and Accessories

• Mechanical Variable Speed Drive: Hand wheel adjustment for precise speed control.
• Pneumatic Activator: Pneumatic hammer to assist material flow and prevent clogging.

Dimensions and Weights

The document includes detailed dimensional drawings and weight specifications for various MBW models, indicating measurements such as inlet and outlet diameters, overall length, and mounting dimensions. Weights range from approximately 8 kg to 85 kg depending on model size.

Critical Notes

• The non-stick materials and tapered screw design are critical to preventing material adhesion and ensuring consistent dosing.
• Pneumatic self-cleaning is recommended for materials prone to sticking or bridging.
• Selection of screw pitch and accessories should be based on material characteristics and required feed rates.
• Standard sealing ensures operational reliability and prevents contamination.
