WR240 Milling Drum 2209684 FB2400 BNT11D22 Holders For WR240/WR240i Milling Machine

Product Details

The part numbers 2209684, FB2400, and BNT11D22 refer to the tool holder system (commonly known as  in Chinese) for the milling drum of WR240 and WR240i machines. These holders are critical components that mount onto the milling drum and securely retain the cutting tools (tool bits) during operation.

While the WR series machines are primarily known as soil stabilizers and recyclers , they share similar holder technology with cold planers. The BNT11D22 designation specifically indicates a quick-change tool holder system designed for high-performance milling and mixing applications

Function and Purpose

The WR240 Milling Drum Holders serve several essential functions within the machine's mixing and milling rotor:

• Tool Retention: The primary function is to securely hold the carbide-tipped cutting tools (bits) in the correct orientation on the rotating drum. The holder features a precisely machined bore that accepts the tool bit shank, allowing the bit to rotate freely while remaining firmly retained.

• Impact Force Transfer: During operation, the holders experience tremendous (impact forces) as the cutting tools engage with asphalt, concrete, or soil. The holder's design transfers these forces from the tool into the drum body, protecting the drum from direct wear and damage .

• Material Mixing: In soil stabilization applications, the holders work in conjunction with the tools to break up existing pavement or soil and mix it thoroughly with binding agents (cement, lime, or foam bitumen).

• Wear Protection: As a sacrificial component, the holder absorbs abrasion from the material mix, protecting the more expensive drum body and base blocks from premature wear .

2. Applicable Machines

These holders are specifically engineered for:

• Primary Models: WR240 and WR240i cold recyclers/soil stabilizers.

• Related Models: Also compatible with WR200, WR200i, and WR250 series machines, as these models share similar rotor designs and holder systems .

The WR series represents Road Milling  range of heavy-duty road recyclers and stabilizers, capable of milling existing pavement structures to depths of up to 500mm while simultaneously mixing in binding agents.

3. Technical Specifications and Design Features

The BNT11D22 quick-change holder system incorporates advanced engineering features for optimal performance :

Material Composition

• Base Material: Manufactured from AISI 8740H high-strength alloy steel, providing exceptional toughness and wear resistance .

• Heat Treatment: Subjected to specialized heat treatment processes to achieve optimal hardness distribution—tough at the core for impact resistance, yet hard on the surface for wear protection.
