Overview: IMER – SPIN 15 Continuous Mixer for Premixed Materials

The IMER – SPIN 15 is a continuous‑cycle mixer that combines dry bagged materials with water in a controlled mixing chamber, then discharges the mixed product continuously at the outlet. Instead of batching one load at a time like a drum mixer, the Spin 15 lets you pour in premixed material and keep the machine running, producing a steady flow as long as you feed it.

IMER describes the Spin 15A (North American model 1106340) as an “industry‑changing, high‑output continuous mixer” specifically built for premixed products in bags. It is simple to use, lightweight for handling, easy to clean, and can be combined with IMER pumps for semi‑automatic spraying or grouting setups.

Key Specifications: IMER SPIN 15

The SPIN 15 is engineered to deliver high output from a compact, 110V‑powered machine.

• Weight (with packing): Approx. 187–196 lb

• Noise level: Under 79 dB, with mixer itself under about 65 dB

These specs show that the IMER – SPIN 15 – Continuous Mixer for Premixed Materials is built for continuous, on‑demand production from a standard 110V outlet.

What the SPIN 15 Mixes and Typical Applications

The SPIN 15 is purpose‑built for premixed, bagged dry materials that only require water at the point of use. IMER specifically lists the following as ideal applications:

• Preblended plasters and rendering mortars

• Premixed masonry mortars and stuccos

• Cementitious and gypsum‑based grouts

• Self‑leveling underlayments (SLU) and toppings

• Preblended conventional floor screeds

• Fine mortars and fireproofing materials

For flooring contractors, IMER notes that the Spin 15 is “the ideal mixer solution” for self‑leveling underlayment or preblended dry‑pack mortar beds on demand. With the ability to mix up to a 50 lb bag per minute and keep material flowing, it is excellent for continuous pours, pump feeding, and spray applications.

Typical use cases include:

• Leveling interior floors before tile, carpet, or wood installations

• Pump‑fed self‑leveling underlayments into large rooms or corridors

• Continuous mixing for spray‑applied plasters, stuccos, and fireproofing when paired with an IMER pump

• Grouting and repair work where a consistent stream of mixed material is needed

Continuous Mixing System and Gearbox Design

The IMER – SPIN 15 – Continuous Mixer for Premixed Materials uses a horizontal mixing chamber and a rotating paddle system to blend material continuously as it moves from the hopper toward the discharge outlet. Dry material is loaded into the top hopper, water is introduced through a regulated water system, and the paddles mix the product as it travels through the chamber.

The mixer is driven by IMER’s maintenance‑free patented parallel‑axis gearbox, which transfers power efficiently from the 1.75 HP motor directly to the paddles. This design offers:

• High torque for starting under load and maintaining throughput

• Reduced maintenance because there are no exposed belts or chains

• Quiet operation with noise levels under typical construction thresholds

Material exits the discharge outlet ready to be collected in buckets, wheelbarrows, or directly into pump hoppers. This continuous flow allows crews to work steadily instead of stopping and starting for each batch.

Water System, Optional Pump, and Mixing Control

Consistent water dosing is critical when mixing premixed materials, and the SPIN 15 offers integrated water management features.

Key water system elements include:

• Micrometric water flow regulator for fine adjustment of water volume

• Optional self‑priming stainless steel electric water pump to pull water from a tank when supply pressure is inadequate

• 10 m water hose with quick couplers (on certain Spin 15A packages)

Operators can adjust water flow to match the manufacturer’s mix ratio and the consistency required for the job (stiffer for floor screeds or dry pack, more fluid for SLU and grouts). Once dialed in, the mixer maintains a very consistent mix as long as bags are loaded steadily into the hopper.

Adjustable Height, Portability, and Jobsite Setup

The IMER SPIN 15 features adjustable legs with three height settings, allowing the loading and unloading height to be tailored to the job. This helps reduce lifting effort when loading bags and makes it easier to discharge material into buckets, wheelbarrows, or pump hoppers.

The machine is compact and designed for easy handling:

• Overall footprint around 28–27.5 inches wide and 54 inches long

• Height adjustable between roughly 37.5 inches and 46 inches depending on leg setting

• Total weight about 187 lb, making it manageable for two people to move with proper equipment

These features make the IMER – SPIN 15 – Continuous Mixer for Premixed Materials well‑suited for interior floors, high‑rise construction (when moved by elevator or hoist), and tight urban jobsites.

Dust Control with iDUST Grate

To address silica dust and air quality concerns, the Spin 15 includes a patented iDUST dust grate system.

• The iDUST grate covers the hopper opening and features multiple vents designed to capture airborne dust.

• A vacuum hose from a suitable shop vac or dust extractor connects to the grate, pulling dust downward as dry bags are dumped in.

This system significantly reduces airborne dust during loading, improving worker comfort and helping sites comply with dust control standards. For indoor SLU, grout, and plaster work, dust management is especially important.

Spin 15 vs. Other Continuous Mixers

Within IMER’s Spin series, the Spin 15 is the more compact continuous mixer compared with the larger Spin 30 Plus. Key distinctions:

• Spin 15:

  • Hopper capacity: 2.12 cu ft / about 250 lb

  • Mixing performance: 0.5 cu ft per minute

  • Ideal for premixed materials, fine mortars, SLU, and grout on small to mid‑sized jobs

• Spin 30 Plus:

  • Larger hopper and higher throughput, suited for bigger projects and when teaming with larger pumps.

Compared to batch drum mixers, the SPIN 15 offers continuous, on‑demand production, tighter control of water ratio, and a cleaner workflow with integrated dust control.

Maintenance, Cleaning, and Z‑Clean Version

The SPIN 15 is designed for easy end‑of‑day cleaning, which is crucial for continuous mixers. IMER also offers a Z‑Clean version with a rubber mixing chamber that further simplifies cleanup and reduces material buildup.

General maintenance and cleaning features:

• Patented IMER mixer coupling for quick disassembly of the mixing section for cleaning

• Rubber mixing chamber (Z‑Clean) option that reduces residual material and noise

• Simple access to paddles and water system for rinsing at the end of each day

Following the Spin 15 manual, operators should flush the mixer with clean water after use and check paddles, seals, and hoses regularly. The maintenance‑free gearbox means fewer lubrication points and less downtime.
