IMER – MIX 200 FP (MORTARMAN) – Portable Vertical Shaft Mixer is a high‑performance specialty mixer engineered to handle demanding mixes like dry pack, mason’s mortar, high‑strength grouts, and fireproofing using standard 120V power. With a powerful 1.5 HP electric motor, 5 cu ft drum capacity, and vertical shaft paddle system, it delivers forced‑action mixing for up to two bags of fireproofing or roughly 170 liters of material per batch.

Overview of the IMER MIX 200 FP Portable Vertical Shaft Mixer

The IMER MIX 200 FP (Fireproofing) is a portable, non‑towable vertical shaft paddle mixer designed to sit directly over sprayer or fireproofing pump hoppers for efficient discharge. It uses IMER’s proven vertical shaft technology from the Mortarman series to provide powerful, forced‑action mixing for premixed bagged materials and traditional mortars that are too stiff or too specialized for ordinary drum mixers.

IMER describes the MIX 200 FP as a vertical shaft mixer “with a powerful mixing action for fireproofing,” capable of mixing two bags of fireproofing per batch on 120V. Its iDUST dust suppression grate, adjustable discharge heights, and compact footprint make it ideal for interior, high‑rise, and large commercial jobs where dust control, consistency, and mobility matter.

Key Specifications: Capacity, Power, and Dimensions

The IMER – MIX 200 FP (MORTARMAN) – Portable Vertical Shaft Mixer is built as a serious contractor‑duty machine with substantial capacity and a robust drive system.

These specs position the MIX 200 FP as a high‑capacity, vertical shaft mixer that still runs on standard 115–120V power, making it uniquely useful on interior and high‑rise jobs.

Vertical Shaft Forced‑Action Mixing System

Like other Mortarman vertical shaft mixers, the MIX 200 FP uses a stationary drum and a vertical shaft with aggressive paddles to deliver forced‑action mixing.

Key mixing design details include:

• Stationary steel tank: The 240 L (approx. 5–6 cu ft) tank does not rotate, reducing splash and making loading/unloading easier.

• Vertical paddle group: A central shaft with multiple paddles sweeps through the full diameter and depth of the tank, cutting, folding, and shearing material for thorough mixing.

• Gear reduction group: A reduction gearbox between the motor and shaft provides high torque at low speed (around 31–32 RPM), ideal for stiff mixes and fireproofing products.

This vertical shaft system is specifically designed for mixes that traditional drum mixers struggle with, such as dry pack mortar, mason’s mortar, high‑strength grouts, and spray‑applied fireproofing materials. It ensures a consistent, lump‑free, well‑hydrated mix every batch.

iDUST Dust Suppression Grate and Loading

The MIX 200 FP is factory‑equipped with IMER’s iDUST dust suppression grate, which is critical for fireproofing and mortar work where silica dust is a major concern.

Features of the iDUST grate:

• Extra‑large opening that allows contractors to quickly load bags of premixed fireproofing or mortar.

• Integrated dust suppression design that works with a vacuum or dust extractor to pull airborne dust down and away from the operator as bags are emptied.

• Protective function: The grate and tank protection prevent access to the mixing area while the mixer is running and also include a bag‑splitting blade to easily open premixed bags during loading.

This makes the IMER – MIX 200 FP (MORTARMAN) – Portable Vertical Shaft Mixer particularly suited for indoor and enclosed environments where dust control is essential.

Adjustable Discharge Heights and Pump Integration

One of the key design goals of the MIX 200 FP is direct integration with fireproofing and spray pumps.

• Adjustable discharge heights: The machine offers three discharge height settings—22 in, 27 in, and 32 in—so you can align the outlet precisely with the hopper of a sprayer or fireproofing pump.

• Non‑towable, stand‑over design: The frame is configured so the mixer can be positioned over pump hoppers or collection containers while remaining stable.

This setup lets crews continuously mix material and discharge directly into the pump, creating a semi‑automatic fireproofing or mortar spraying system that greatly increases productivity.

Materials and Applications

Although the Model MIX 200 FP is marketed primarily for fireproofing, it is a Mortarman‑class vertical shaft mixer suitable for a range of stiff and specialty materials.

According to IMER and dealers, it is ideal for:

• Fireproofing mixes: Designed to handle two bags of premixed fireproofing per batch on 120V.

• Dry pack mortar and floor screeds: Stiff mixes for floor leveling and sloped beds.

• Mason’s mortar: Mortar for block, brick, and stone masonry.

• High‑strength grouts and repair mortars.

• Traditional mortars and other premixed bagged materials that need forced‑action mixing.

IMER’s vertical shaft mixers are known as “the mixer for impossible jobs,” able to mix up to 3/8 in aggregate and even mix stiff mud dry, which also applies to the MIX 200 FP’s capabilities.

Portability and Jobsite Handling

Despite its 573 lb weight, the MIX 200 FP is categorized as a portable vertical shaft mixer rather than a towable trailer unit.

Portability features include:

• Transport wheel kit with 15 in wheels for moving the mixer around the jobsite.

• Compact footprint of about 54 in long and 30 in wide, allowing it to fit into tighter spaces than full‑size towable mixers.

• Designed to be loaded by forklift or hoist using the support frame for placement over pump hoppers in multi‑story or large commercial projects.

This configuration makes the IMER – MIX 200 FP (MORTARMAN) – Portable Vertical Shaft Mixer particularly useful on large interior jobs, high‑rise fireproofing projects, and industrial sites where traditional tow‑behind mixers are impractical.

Safety, Noise, and Electrical Protection

The MIX 200 FP is built to meet modern safety and electrical standards for construction equipment.

From the instruction manual:

• Electrical safety:

  • Complies with EN 60204‑1, with an electrical safety device that prevents operation when the drum protection is open.

  • Includes a system to prevent automatic restart after a power interruption.

  • Features a thermal‑magnetic protection switch for electrical equipment.

• Mechanical safety:

  • Protective guards over drive belts and hazardous points.

  • Tank protection and chute guards prevent access to the mixing area during operation.

• Noise levels:

  • Sound pressure level at operator ear: 70 dB(A).

  • Guaranteed sound power level: 81 dB(A).

These measures help protect operators from accidental contact, unexpected restarts, and excessive noise, making day‑to‑day operation safer and more comfortable.

Maintenance and Durability

The MIX 200 FP is a Mortarman‑class vertical shaft mixer, designed for long service life with demanding mixes.

Key durability and maintenance points:

• Heavy‑duty support frame, tank, and paddles built to withstand abrasive materials like fireproofing and dry pack.

• Easy access to belt guards for checking and tensioning drive belts as needed.

• External pillow‑block bearings support the shaft and are accessible for inspection.

• Recommended cleaning procedure:

  • Always stop the machine before cleaning.

  • Flush and scrape the tank after each batch or at the end of the day to prevent buildup.

  • Avoid inserting tools or body parts into the drum while in operation.

Following IMER’s maintenance guidelines helps ensure consistent mixing performance and extends the life of belts, paddles, and the drive system.
