Shotcrete applications require reliable equipment for mixing, preparing, and delivering material to the placement area. In refractory construction and repair, the ability to maintain consistent material flow and high-pressure delivery can be particularly important.
The Blastcrete MX-20CM is a combined mixer and pump designed for refractory placement, including rugged shotcrete applications. As a shotcrete pump and shotcrete mixer pump, the MX-20CM integrates a high-shear continuous mixer with a secondary mixer and a 4-inch high-pressure swing tube piston pump.
With a stated output range of approximately 2–3 tons per hour for smaller installations and up to 25 tons per hour for high-volume applications, the MX-20CM provides flexibility for different project requirements.
What Is a Shotcrete Pump?
A shotcrete pump is equipment used to transport prepared concrete or refractory material through a delivery system to the placement area. Pumping allows material to be delivered to locations where conventional placement methods may be difficult or inefficient.
The MX-20CM is specifically designed for refractory placement and is suitable for rugged refractory pump-cast and shotcrete applications.
Its high-pressure pumping system includes:
4" x 36" swing tube piston pump
2,200 PSI piston face pressure
0–25 tons/hour pump output
Hydraulic receiving hopper agitator
Swing-out receiving hopper
MX-20CM Shotcrete Mixer Pump
The MX-20CM combines mixing and pumping into one integrated machine.
Instead of relying on separate equipment for material preparation and pumping, the system incorporates:
Dry material hopper
High-shear continuous mixer
Secondary mixer
Receiving hopper
High-pressure swing tube pump
The material flow can be summarized as:
Dry Material → High-Shear Mixer → Secondary Mixer → Receiving Hopper → Pump → Shotcrete Placement
This configuration is designed to provide continuous material preparation and delivery.
High-Shear Continuous Mixer
A key component of the MX-20CM is its compact, high-shear continuous mixer.
The primary mixer is designed to hydrate the material before it reaches the receiving hopper.
Mixer Capacity
The mixer has a stated output of up to 25 tons per hour.
This makes the MX-20CM suitable for both smaller shotcrete-related refractory projects and higher-volume applications, depending on the material and installation requirements.
Secondary Mixing Stage
The MX-20CM also incorporates a medium-shear secondary mixer mounted in the receiving hopper.
This provides an additional stage of material processing before pumping.
The two-stage mixing system is designed to help prepare the material for the high-pressure pumping process.
High-Pressure Shotcrete Pump
The MX-20CM uses a 4-inch x 36-inch ultra-high-pressure swing tube pump.
The pump is designed for demanding refractory pump-cast and shotcrete applications.
Pump Performance
Pump output: 0–25 tons/hour
Piston face pressure: 2,200 PSI
Pump: 4" x 36" swing tube piston pump
Receiving hopper: 1,500 lb capacity
Hopper agitator: Hydraulic
The pump's oversized differential cylinders are designed to provide high discharge pressure while operating at comparatively lower hydraulic pressure.
Shotcrete Applications
The MX-20CM can support suitable shotcrete applications in demanding industrial environments.
Potential applications include:
Refractory shotcrete
Furnace repair
Kiln maintenance
Industrial refractory installation
Steel plant refractory work
Foundry furnace maintenance
Boiler refractory repair
High-temperature equipment repair
Pump-cast refractory placement
Industrial maintenance projects
The specific material and shotcrete process should always be matched to the manufacturer's recommendations for the refractory product being installed.
Refractory Shotcrete Pump for Industrial Applications
Industrial refractory applications often involve challenging working environments and large quantities of material.
The MX-20CM's integrated mixer and pump can help simplify material handling by combining preparation and delivery in one machine.
The system can support:
Continuous material mixing
High-pressure material delivery
High-volume refractory placement
Smaller repair applications
Pump-cast applications
Shotcrete installation
Actual output will depend on the material, mix design, hose arrangement, pumping distance, and jobsite conditions.
Swing-Out Receiving Hopper
The MX-20CM features a swing-out receiving hopper designed to provide easier access to the swing tube section.
This feature can simplify:
Pump cleaning
Swing tube inspection
Routine maintenance
Material removal
Service access
Forklift tubing is mounted to the lower hopper to assist with flat-pack removal.
Reduced Dust During Material Charging
The continuous mixer is designed to minimize dust generated during charging.
The supplied manufacturer information also states that the continuous mixer can be cleaned more quickly and generates very little waste during cleanup.
For contractors performing multiple shotcrete or refractory projects, simplified cleaning can help reduce equipment downtime.
Shotcrete Mixer Pump Output
The MX-20CM is designed to handle a broad range of production requirements.
Smaller Applications
The machine can be used for smaller refractory installations at approximately 2–3 tons per hour.
High-Volume Applications
The mixer and pump have a stated maximum output of 25 tons per hour.
This allows one machine to be used across different project scales, subject to material and application requirements.
MX-20CM Power Options
The MX-20CM is available with multiple power configurations.
Diesel Power
99 HP John Deere water-cooled diesel
102 HP Deutz water-cooled diesel
Electric Power
Dual electric motors
The integrated mixer and pump system is designed to require approximately 100 HP.
The supplied information states that fuel consumption can be reduced by 50% compared with competitive machines. Actual fuel consumption depends on operating conditions, material, workload, and machine configuration.
