Efficient mixing and pumping are essential for projects that require reliable material delivery and consistent placement. The Blastcrete MX-20CM combines a high-shear continuous mixer with a high-pressure swing tube piston pump, creating an integrated system for demanding refractory pump-cast and shotcrete applications.
While commonly described as a concrete mixer pump, the MX-20CM is specifically designed around refractory placement. Its two-stage mixing system and high-pressure pump can provide a practical solution for contractors handling refractory materials and suitable shotcrete applications.
What Is a Concrete Mixer Pump?
A concrete mixer pump combines material mixing and pumping functions in one machine. Instead of preparing material separately and then transferring it to a pump, an integrated system can continuously mix and deliver material through a pumping system.
The MX-20CM uses:
A high-shear continuous primary mixer
A medium-shear secondary mixer
A hydraulic receiving hopper
A 4-inch high-pressure swing tube piston pump
This configuration allows material to move through the system from mixing to pumping in a continuous process.
MX-20CM High Pressure Concrete Pump
The MX-20CM features a 4-inch x 36-inch ultra-high-pressure swing tube piston pump.
The pump is designed for rugged refractory pump-cast and shotcrete applications and has a stated piston face pressure of 2,200 PSI.
Pump Specifications
Pump size: 4" x 36"
Pump type: Ultra-high-pressure swing tube piston pump
Output: 0–25 tons/hour
Piston face pressure: 2,200 PSI
Receiving hopper capacity: 1,500 lb
Hydraulic hopper agitator
The pump's oversized differential cylinders are designed to provide high discharge pressure while requiring comparatively lower hydraulic pressure for operation.
Two-Stage Mixing Technology
One of the important features of the MX-20CM is its two-stage mixing process.
Primary High-Shear Mixer
The first stage uses a compact high-shear continuous mixer where the material is hydrated.
The mixer has a stated maximum output of 25 tons per hour.
Secondary Mixer
A medium-shear secondary mixer is mounted inside the receiving hopper.
This provides another stage of material mixing before the material enters the high-pressure pump.
The overall process is:
Dry Material → High-Shear Mixing → Secondary Mixing → Receiving Hopper → High-Pressure Pump → Placement
This integrated configuration is designed specifically to support continuous refractory material preparation and delivery.
High Pressure Concrete Pumping Capability
The high pressure concrete pump terminology is often used for equipment capable of delivering material through a pumping system at elevated pressure.
For the MX-20CM, the manufacturer specifies 2,200 PSI piston face pressure and a maximum pump output of 25 tons per hour.
Actual output and pumping performance can vary depending on:
Material formulation
Aggregate characteristics
Hose diameter
Hose length
Vertical lift
Material temperature
Jobsite conditions
Pump configuration
The machine should be operated according to the applicable material and equipment manufacturer's recommendations.
Applications for the MX-20CM
The MX-20CM is designed for refractory placement and can be suitable for various demanding industrial applications.
Potential applications include:
Refractory pump casting
Shotcrete applications
Furnace repair
Kiln maintenance
Boiler refractory work
Steel plant refractory installation
Foundry maintenance
Industrial furnace lining
Refractory repair
High-volume refractory placement
The MX-20CM should not be treated as a generic ready-mix concrete pump without confirming material compatibility. Its supplied specifications specifically emphasize refractory pump-cast and shotcrete applications.
Production Capacity
The MX-20CM is designed to accommodate different production requirements.
For smaller refractory installations, it can be used at approximately 2–3 tons per hour.
For high-volume installations, both the mixer and pump are rated for output of up to 25 tons per hour.
This range provides flexibility for contractors working on both smaller maintenance projects and larger industrial installations.
High-Shear Continuous Mixer
The high-shear continuous mixer is designed to hydrate the material before it reaches the receiving hopper.
This continuous mixing approach can help provide a steady material supply to the pumping system.
The stated mixer output is:
0–25 tons per hour
The two-stage design also includes a medium-shear secondary mixer in the receiving hopper.
Swing-Out Receiving Hopper
The MX-20CM includes a swing-out receiving hopper designed for convenient access to the swing tube section.
This design can make routine cleaning and maintenance easier.
The hopper arrangement can assist with:
Swing tube access
Cleaning
Inspection
Maintenance
Material removal
Forklift tubing is also mounted to the lower hopper for flat-pack removal.
Reduced Dust and Faster Cleanup
Charging a continuous mixer can potentially create dust and material waste.
The MX-20CM is designed to substantially reduce dust generated during charging. The manufacturer also states that cleanup of the continuous mixer is quicker and generates very little waste.
For industrial contractors, easier cleanup can help simplify equipment maintenance between applications.
MX-20CM Power Options
The MX-20CM is available with multiple power configurations.
Diesel Options
99 HP John Deere water-cooled diesel
102 HP Deutz water-cooled diesel
Electric Option
Dual electric motors
The machine's two-stage mixer and pump design requires approximately 100 HP.
The supplied information states that the design can reduce fuel consumption by 50% compared with competitive machines. Actual consumption will depend on operating conditions, material, workload, and configuration.
