IMER – MIX 750 (MORTARMAN) – Towable 18CF Output, Vertical Shaft Mortar Mixer is a high‑capacity, mini batch‑plant style mixer built for contractors and precast operations that need to mix up to 18 cubic feet (about 1,600–1,700 lbs) of mortar, dry pack, stucco, sand‑cement, or small‑aggregate concrete every three to four minutes. With a 22 cu ft drum, powerful gas or electric drive options, and a towable chassis, it delivers production levels far beyond conventional mortar mixers while maintaining excellent mix quality and jobsite safety.

Overview of the IMER MIX 750 (Mortarman) Vertical Shaft Mortar Mixer

The IMER Mix 750 (also known as Mortarman 750 or Mix 750 Plus) is a towable vertical shaft mixer that uses batch‑plant technology in a compact, jobsite‑ready format. Instead of rotating a barrel, the MIX 750 keeps its 22 cu ft drum stationary and uses a vertical shaft with multi‑arm paddles to create intense forced‑action mixing.

IMER describes the MIX 750 as a “mini batch plant” designed to produce between 9 and 18 cubic feet of mud every three to four minutes, making it a perfect partner for busy precast operations and large masonry, stucco, or refractory jobs. The safety grate, discharge system, and frame have been refined over time to improve access for cleanup, protect the outlet from mud buckets or forklifts, and enhance towing stability.

Drum Capacity, Output, and Power Options

As a Towable 18CF Output, Vertical Shaft Mortar Mixer, the MIX 750 offers some of the highest capacity in IMER’s Mortarman lineup.

Drum and output

From IMER and major distributors:

• Drum capacity: 22 cu ft

• Batch output: 16–18 cu ft (approx. 1,600–1,700 lbs of material)

• Minimum batch: around 6–7 cu ft (useful for smaller runs)

• Drum diameter: 51–52 in

• Maximum aggregate size: 3/8 in

This means the MIX 750 can mix up to about 1,600 lbs of mortar, dry pack, stucco, or sand‑cement per batch, with enough torque to handle very low‑slump materials.

Motor and engine options

Different configurations are available to match jobsite power and application needs:

• Gas engine:

  • 13 HP Honda gas engine with electric start (e.g., model 1194648).

• Electric motors:

  • 5 HP 220V single‑phase electric motor.

  • 7.5 HP 220V 3‑phase electric motor (and some 440V 3‑phase options in certain spec listings).

• “Mixer without motor” option (1194640) for integrating with existing power sources.

The powerful 5–7.5 HP electric motors or 13 HP Honda engine are paired with “monster” gearboxes developed in IMER’s batch‑plant division to deliver enormous mixing torque for tough mixes.

Vertical Shaft Forced‑Action Mixing System

The MIX 750’s key advantage is its vertical shaft mixing system, which works like a mini batch plant rather than a typical mortar mixer.

Mixing system features:

• Vertical shaft with multiple arms and blades that sweep the entire drum diameter and depth.

• Rubber inserts on the blades that scrape the drum bottom and sides, helping to clean the mixing drum and reduce buildup.

• Generously sized drum bottom designed to reduce wear and improve discharge.

• Newer gearbox design guaranteeing high torque even with the most difficult mixes.

Because the paddles cut through the mix, the MIX 750 can handle materials from dry to wet, including:

• Mortar (block, brick, stone)

• Dry pack/deck mud

• Stucco and plaster

• Sand‑cement screeds and toppings

• Concrete with up to 3/8 in aggregate

• Refractory and specialty mixes

IMER’s marketing and dealer descriptions repeatedly emphasize that the Mortarman 750 can “mix 1600 lbs of mortar, dry pack, stucco, or sand & cement” and can mix concrete up to 3/8 in aggregate size.

Towable Chassis, Suspension, and Discharge

The IMER – MIX 750 (MORTARMAN) – Towable 18CF Output, Vertical Shaft Mortar Mixer is built on a robust towable frame for highway and jobsite use.

Tow and chassis features:

• Tow package included: bar and hitch, with a low and wide design for towing safety and speed.

• Pneumatic highway tires: 22 in tires with torsion bar suspension for improved ride quality and stability.

• Forklift pockets: built‑in pockets allow safe loading, unloading, and repositioning with a forklift.

• Extra‑wide stability legs: telescopic foot stands slide outward to accommodate a wide variety of mud pans and can be adjusted up or down to fine‑tune discharge height.

Discharge outlet:

• Discharge outlet height: around 29–30 in max / 23 in min, depending on leg adjustment.

• Protected outlet: the discharge system is designed to be easier to open and close and is better protected from being struck by mud buckets or forklifts, improving durability.

Together, these features allow the MIX 750 to function like a mini batch plant, feeding mud tubs, wheelbarrows, or precast molds with precise control.

Safety Grate, iDust Option, and Low‑Maintenance Gearbox

Safety and ease of use are central to the Mortarman 750 design.

Safety grate and access:

• One‑piece hinged safety grate:

  • Improved and now hinged, providing quick, full access for cleanup.

  • Auto‑shutoff: Lifting the grate automatically stops the paddles, protecting operators from contact while loading or cleaning.

  • Integrated bag splitter: Grate bars and blades help split bags, speeding up loading without extra tools.

Dust control (on newer or optional setups):

• iDUST style grates (used across IMER mixers) can be paired with a HEPA vacuum to pull dust down during loading, helping reduce airborne silica.

Low‑maintenance drivetrain:

• Sealed shaft bearings and heavy‑duty gearboxes reduce lubrication points and wear.

• Oil‑bath gearbox requires far less daily attention than exposed crown gears and external bearings on older mixers.

These features make the MIX 750 safer and easier to own compared to traditional mortar mixers with open gears and minimal guarding.

Typical Applications and Ideal Users

The IMER MIX 750 (Mortarman) is positioned as a high‑capacity mixer for professional and industrial users.

Ideal users include:

• Precast plants and GFRC operations: Fast, thorough mixing for precast panels, architectural elements, and GFRC backer/face coats.

• Masonry contractors: Large‑scale block, brick, and stone projects where high mortar volumes are needed.

• Stucco and façade contractors: Large residential and commercial stucco jobs requiring continuous production.

• Refractory and industrial maintenance crews: Mixing refractory castables and repair mortars for kilns, furnaces, and industrial plants.

• Decorative and specialty concrete shops: Mixing sand‑cement blends, toppings, and small‑aggregate concrete with tight quality control.

For operations that have outgrown mid‑size mixers like the Mix 120 or Mix 360, the MIX 750 offers a significant step up in capacity and throughput without the cost and footprint of a full‑scale batching plant.

Productivity Advantages of the Towable 18CF Output Vertical Shaft Design

The MIX 750’s Towable 18CF Output, Vertical Shaft Mortar Mixer design offers several productivity advantages:

• High‑volume mixing: Up to 18 cu ft per batch, or roughly 1,600–1,700 lbs, every three to four minutes.

• Forced‑action blending: Vertical shaft paddles ensure fast, homogeneous mixes, especially with low‑slump or high‑strength materials.

• From dry to wet: Can mix materials from very dry pack to fluid mortars and concretes.

• Quick discharge and recharging: Efficient discharge system clears the drum fast so you can start the next batch almost immediately.

Dealers and IMER literature describe the MIX 750 as providing “mini batch plant production for the cost of a mortar mixer,” highlighting its ability to keep up with busy crews and precast operations.

Maintenance, Durability, and Long-Term Value

The IMER – MIX 750 (MORTARMAN) – Towable 18CF Output, Vertical Shaft Mortar Mixer is engineered for durability in high‑duty environments.

Durability features:

• Heavy, welded steel frame and drum designed to withstand constant loading, mixing, and discharge.

• Telescopic stability legs and torsion bar suspension built for repeated towing and jobsite setup.

• Rubber‑tipped paddles and generously sized drum bottom reduce wear and help keep the drum cleaner.

Maintenance best practices:

• Clean the drum and paddles thoroughly after each use, especially when mixing dry pack or refractory materials.

• Inspect gearbox seals, shafts, and paddle hardware periodically according to IMER’s Mortarman manuals.

• Service gas engines (where applicable) per Honda’s schedule, and ensure proper voltage for electric motors.

With proper care, the MIX 750 can serve as a central production unit for many years, providing strong ROI for contractors and plant operators.
