Imer Outer Blade for Mortarman 120 Plus

Features

• Outer metal paddle for the Mortarman 120 Plus
• Does not include rubber scraper

The Imer Outer Blade for Mortarman 120 Plus is a genuine OEM metal paddle designed specifically for the Imer Mortarman 120 Plus (also known as the Imer Mix 120 Plus) vertical shaft mixer, ensuring optimal mixing performance and long service life for masonry and construction professionals.

What Is the Imer Outer Blade for Mortarman 120 Plus?

The Imer Outer Blade for Mortarman 120 Plus is the outer metal paddle that mounts inside the drum of the Mortarman 120 Plus vertical shaft mixer. It works in combination with the inner and middle paddles to thoroughly mix mortar, grout, stucco, and similar materials. The part is typically identified by Imer as the “Outer Paddle” or “Outer Blade,” with part number PN 3229588 for the MIX 120 Plus / Mortarman 120 Plus.

This blade is engineered to match the mixer’s 120-liter drum and approximate 90-liter mixing capacity, rotating at about 38 rpm in a clockwise direction when viewed from the loading mouth. Because it is an OEM component, the blade maintains the correct geometry, clearances, and durability that the mixer was designed for, preventing issues associated with non‑genuine or modified parts.

Key Features and Specifications

The Imer outer blade is built to handle demanding jobsite conditions while providing consistent, homogeneous mixes batch after batch. While exact dimensions are specified in Imer’s technical documentation, several core characteristics define this part.

• Outer metal paddle for Mortarman 120 Plus / MIX 120 Plus vertical shaft mixer.

• Designed to mount on the mixer head assembly along with inner and middle blades.

• Heavy‑duty metal construction for high wear resistance in abrasive mixes.

• Intended for use with the rubber outer blade scraper in some configurations, where a rubber component bolts to the metal paddle or is supplied as part of a kit.

• OEM part number PN 3229588, listed as “Outer Paddle for IMER MIX 120 Plus Vertical Shaft Mixer.”

This blade integrates into the mixer’s vertical shaft system, which includes the mixer head, inner blade (PN 3229594), middle blade (PN 3230023), and shaft scraper (PN 3230013). Together, these components deliver a planetary‑style mixing action that scrapes the sides and bottom of the drum for a thorough blend.

Role of the Outer Blade in Mixing Performance

The outer blade has a critical role in how the Mortarman 120 Plus mixes materials, particularly along the drum wall and perimeter.

• It sweeps along the inner surface of the drum, helping to pull material from the sides back into the main mixing zone.

• In setups that include rubber scrapers or rubber paddle kits, the outer blade and its attached rubber section improve cleaning action and reduce material build‑up on the walls.

• By working in combination with the inner and middle paddles, the outer blade contributes to fast, consistent mixing and helps eliminate cold spots or unmixed pockets.

The Mortarman 120 Plus is designed as a vertical shaft mixer specifically to achieve uniform mixing in relatively small, controlled batches, and the outer blade is an essential component of that system. A worn or damaged outer blade can reduce efficiency, lengthen mixing times, and increase manual cleaning requirements, which is why keeping this part in good condition is important.

Outer Blade vs. Rubber Blades and Paddle Kits

When researching or purchasing an Imer outer blade for the Mortarman 120 Plus, it is important to distinguish between the bare metal outer blade and the various rubber blade kits and accessory paddle kits offered for the mixer.

• The “Outer Blade” or “Outer Paddle” (PN 3229588) is the metal paddle component that mounts to the mixer head.

• The “Outer Blade Rubber” or similar rubber components (for example, external blade rubber) are separate parts that attach to metal blades or are supplied as part of a rubber kit.

• The Imer 1107618 rubber paddle kit for the Mix 120 Plus / Mortarman 120 Plus includes metal face plates, rubber scrapers, and mounting hardware to upgrade or refresh the paddle system with rubber scrapers.

These kits are designed to add or replace rubber scrapers on the paddles so they clean the drum more effectively and reduce residue. For many users, the ideal setup is an OEM outer blade combined with the appropriate rubber scrapers and mounting hardware, which yields both durability and excellent scraping performance.

Compatibility: Mortarman 120 Plus and MIX 120 Plus

Imer references this mixer under both “Mortarman 120 Plus” and “MIX 120 Plus,” but they refer to the same vertical shaft mixer platform. Parts sites and manuals consistently list the outer paddle PN 3229588 for this model, confirming compatibility across both name variants.

• The Mortarman 120 Plus vertical shaft mixer features a 120‑liter drum and approximately 90‑liter mix capacity.

• The outer blade is part of the standard paddle assembly for this mixer and appears in the OEM parts diagram and parts list.

• Dedicated Imer parts suppliers and Imer’s own parts listings categorize PN 3229588 specifically under Mortarman 120 Plus / MIX 120 Plus mixer parts.

If your mixer is labeled Mortarman 120 Plus, MIX 120 Plus, or Mortarman 120 Plus vertical shaft mixer, PN 3229588 is the correct OEM outer blade in most standard configurations. Always confirm the model plate on your machine and cross‑check with the parts breakdown for complete certainty.

OEM Part Numbers and Related Components

For maintenance and ordering, knowing the correct part number and related components is essential. The Mortarman 120 Plus parts diagram lists several key items associated with the outer blade:

• Outer blade / outer paddle: PN 3229588.

• Inner blade: PN 3229594.

• Middle blade: PN 3230023.

• Scraper: PN 3230013.

• External blade rubber / outer blade rubber: separate part numbers in the rubber blades kit (e.g., 3235359 or similar, depending on configuration).

There is also a full rubber paddle kit, part number 1107618, marketed as the Mix 120 Plus / Mortarman Rubber Paddle Kit or Accessory Paddle Kit. This kit adds rubber scrapers to the mixer, including metal face plates, rubber scrapers, and mounting hardware, and is installed with a 3/8‑inch drill bit in most cases.

Benefits of Using a Genuine Imer Outer Blade

Using a genuine Imer outer blade for the Mortarman 120 Plus offers several advantages over generic or improvised alternatives.

• Correct fit and alignment: The OEM blade aligns properly with the inner and middle paddles, preventing interference and ensuring smooth rotation at the specified paddle rpm.

• Optimal mixing performance: The geometry of the blade is matched to the drum design, which promotes thorough mixing and reduces the risk of unmixed material sticking to the sides.

• Durability and longevity: Genuine blades are built to withstand abrasive aggregates and repeated use, particularly when combined with rubber scrapers that reduce direct metal‑to‑drum contact.

• Protecting the gearbox and drive: Properly balanced and correctly installed paddles reduce stress on the mixer’s gearbox, main shaft, and bearings, which are detailed in the gearbox parts list.

Many professional contractors choose to maintain their Mortarman 120 Plus mixers with OEM parts because downtime on the jobsite can be costly, and a correctly functioning paddle system is central to mixer performance.

Installation and Replacement Considerations

While specific step‑by‑step instructions for replacing the outer blade should always come from the official Imer manual, the overall process follows general mixer maintenance guidelines.

• Disconnect power and ensure the mixer is fully switched off before performing any maintenance or repairs.

• Access the mixer head and paddles by following the manual’s safety and disassembly instructions, including removing guards where required.

• Remove the hardware holding the existing outer blade and note the order and orientation of any washers, spacers, and rubber components.

• Install the new OEM outer blade (PN 3229588) using the recommended bolts and nuts, tightening them to the appropriate torque as indicated in Imer’s documentation.

• If you are adding or replacing rubber scrapers with the 1107618 kit, mount the metal face plates, rubber scrapers, and hardware according to the kit instructions, typically using a 3/8‑inch bit with a drill.

After installation, operators should perform a brief test run without load to verify that the paddles rotate freely, the outer blade clears the drum correctly, and there is no abnormal noise or vibration. Regular checks for wear and for build‑up of material on the blades are recommended in the maintenance sections of the manual.
