With a powerful 3 HP single‑phase motor, 500 lb hopper capacity, and 1 cu ft per minute mixing performance, the Spin 30 Plus is built for medium and large construction sites that demand constant, on‑demand material production.

What is the IMER – SPIN 30 – Continuous Mixer for Premixed Materials – 1106152?

The IMER Spin 30 Plus (Model 1106152) is a continuous‑cycle mixer designed for premixed, bagged dry materials or for materials supplied from a silo via a conveying system. Unlike batch drum mixers, the SPIN 30 automatically blends dry product with water in a horizontal mixing chamber and discharges a steady stream of mixed material as long as the hopper is fed.

IMER describes the Spin 30 as a portable high‑output continuous mixer, ideal for pre‑blended plasters, masonry mortars, stuccos, grouts, self‑leveling underlayments (SLU), and pre‑blended conventional floor screeds. Contractors can also team the continuous mixer with an IMER spray and grout pump to create a semi‑automatic mixing and pumping station for large walls, floors, and fireproofing projects.

Materials the SPIN 30 is Designed to Mix

The Spin 30 Plus is specifically optimized for premixed dry products that require only water on site. IMER highlights the following materials as ideal for this mixer:

• Preblended plasters and rendering mortars

• Masonry mortars and stuccos

• High‑strength grouts and repair mortars

• Self‑leveling underlayments and toppings

• Preblended conventional floor screeds

• Fireproofing and fine mortars

For flooring specialists, IMER notes the Spin 30 Plus as “the ideal mixer solution for making self‑leveling underlayment or pre‑blended dry‑pack mortar beds on demand,” thanks to its high throughput and precise water control.

Because it uses a continuous mixing process, the SPIN 30 is especially effective when paired with pumps to spray plasters, stuccos, and fireproofing or to pump SLU and grout long distances.

Continuous Horizontal Mixing System and Gearbox

The IMER – SPIN 30 – Continuous Mixer for Premixed Materials – 1106152 uses a horizontal mixing system with an auger‑type batching screw and mixing paddles driven by a patented parallel‑axis gearmotor.

Key components described in the Spin 30 Plus technical manual include:

• Auger‑type batching system that conveys dry material from the hopper into the mixing chamber.

• Horizontal mixer with paddles that thoroughly blend dry material with water.

• Water circuit with pump and adjustable flow meter that injects water at the correct point into the chamber.

• Maintenance‑free patented parallel‑axis gearbox transmitting high torque from the 3 HP motor to the auger and paddles.

This system allows the Spin 30 to start under full load and maintain a constant 1 cu ft/min output, even with heavier mortars and grouts. The gearbox design also keeps operation relatively quiet while reducing maintenance compared to belt‑driven systems.

Water Pump, Flow Meter, and Consistency Control

Consistent water proportioning is crucial when working with premixed materials, and the Spin 30 Plus includes a complete water management system.

Standard water‑related features include:

• Stainless steel water pump (booster pump) to feed water from a tank or when jobsite water pressure is low.

• Adjustable water flow meter (liters per hour) for precise control of water dosage.

• Integrated water circuit that injects water directly into the mixing chamber at the proper stage.

Operators can calibrate the water flow to match manufacturer specifications for each product and fine‑tune consistency for different applications (stiffer for floor screeds and dry pack, more fluid for self‑leveling underlayments and some grouts). Once set, the Spin 30 maintains very consistent mix quality, batch after batch, as long as the hopper is fed regularly.

iDUST Dust Suppression Grate and Safety Features

To control silica dust and improve jobsite safety, the Spin 30 Plus comes standard with the IMER iDUST dust suppression grate.

• The iDUST grate covers the hopper opening and includes multiple vents designed to capture airborne dust as bags are emptied.

• A vacuum hose from an appropriate dust extractor connects to the grate, pulling dust downward and away from the operator.

This system “significantly reduces the dust created when loading the material while keeping the work environment clean,” especially during bag loading. The hopper grate also includes a bag splitter and safety interlock so the mixer cannot run with the grate open, enhancing operator safety.

These features make the IMER – SPIN 30 – Continuous Mixer for Premixed Materials – 1106152 well suited for indoor work and for job sites that must comply with strict dust control standards.

Hopper Capacity, Output Rate, and Productivity

With a 500 lb hopper and 1 cu ft/minute mixing performance, the Spin 30 Plus is built for high productivity.

From IMER and distributor descriptions:

• Hopper/tank capacity: 500 lb of dry material (approx. 110 liters).

• Mixing performance: 1 cu ft/min (around 30–35 liters/min).

• Throughput: Mix up to two 50 lb bags per minute when operated continuously.

This high‑output “on‑demand” mixing system allows crews to:

• Keep large SLU placements supplied without interruption.

• Feed plaster and stucco pumps for continuous wall spraying.

• Supply grout or screed crews with a steady flow of material.

Compared with smaller continuous mixers, the Spin 30 Plus is particularly suited to medium and large sites where downtime between batches would be costly.

Portability, Dimensions, and Jobsite Handling

Despite its output, the IMER – SPIN 30 – Continuous Mixer for Premixed Materials – 1106152 remains relatively compact and portable.

Key handling features:

• Dimensions: 71" long × 25" wide × 46" high.

• Weight: Approximately 281 lb.

• Oversized solid rubber wheels for easier transport, even on rough terrain.

• Integrated lifting hooks to move the unit with a crane or forklift on larger projects.

The frame is robust but straightforward, designed to be light enough to maneuver yet strong enough for daily use on commercial sites. Adjustable height positions are available to align the discharge with buckets, wheelbarrows, pump hoppers, or floor level for SLU work.

By providing a constant stream of mixed material, the Spin 30 reduces labor required for manual batching, minimizes waste, and improves overall jobsite efficiency.

Maintenance, Cleaning, and IMER Quality

The SPIN 30 Plus is designed for straightforward cleaning and low maintenance.

Important features for upkeep include:

• IMER maintenance‑free patented parallel‑axis gearbox with no routine lubrication points.

• Patented IMER mixer coupling for quick disassembly of the mixing section, simplifying cleaning and service.

• Water circuit and mixing chamber accessible for flushing at the end of each day.

The Spin 30 Plus manual explains that after use, operators should run clean water through the mixer, briefly operate the paddles, and clean any residual material from the chamber, hopper, and outlet. With proper care, the durable frame, motor, and gearbox are built for long life in demanding environments.

IMER’s reputation for Italian‑made, professional‑grade equipment is underscored in distributor notes that the Spin 30 Plus is “100% IMER production – Made in Italy.” Parts, technical support, and product documentation are available through IMER USA and its dealer network.
