Paste Backfill Plant
Precision Engineered Paste Backfill Plants for Modern Underground Mining
More Than a Paste Backfill Plant. A Better Mining Process.
Every hour your mine spends waiting on inconsistent backfill is an hour of lost production. Every pound of excess cement increases operating costs. Every interruption in the backfill process can delay mining schedules, reduce ore recovery, and impact profitability.
Your paste backfill plant shouldn’t become another challenge to manage. It should become one of your greatest operational advantages. That’s why mining companies around the world trust CMQ Engineering.
For more than 60 years, we’ve engineered complete material handling and batching systems that deliver reliable performance in some of the world’s most demanding environments. Our paste backfill plants are designed to produce consistent, accurately blended paste while maximizing uptime, minimizing binder consumption, and supporting continuous mining operations.

Static Backfill Paste Plant.
Every Mine Is Different.
Your Paste Backfill Plant Should Be Too.
No two underground mines operate under the same conditions. Tailings characteristics vary. Binder recipes change. Production rates differ. Pipeline lengths increase. Ore bodies evolve. Yet many manufacturers simply offer standardized equipment and expect it to perform under every condition.
CMQ Engineering takes a different approach.
Every paste backfill plant we build is engineered specifically around your operation. Our engineers work closely with your team to develop a system that matches your production goals, tailings characteristics, site layout, and long-term mining strategy.
Because when every mine is unique… Your backfill plant should be, too.

Precision That Pays for Itself
Better Blending. Lower Binder Costs.
In paste backfill production, accuracy matters. Cement is one of the highest operating costs in any backfill system. Even small variations in binder content can cost thousands of dollars over the life of a project.
CMQ Engineering paste backfill plants are designed to achieve blending accuracy within 0.5%, helping produce a consistent, repeatable paste while reducing unnecessary binder consumption.
The result is:
- Consistent paste quality
- Reduced cement waste
- Predictable compressive strength
- Lower operating costs
- Greater confidence in every batch
Precision isn’t simply about quality. It’s about profitability.

Engineered Around Reliability
Keep Your Mine Moving.
Underground mining doesn’t stop because a backfill plant isn’t ready. Every delay affects production. Every hour of downtime costs money. That’s why reliability is built into every CMQ Engineering system.
Our paste backfill plants are designed to deliver dependable production with industrial-duty components, proven batching technology, and intelligent automation that keeps your operation moving shift after shift.
Because the most productive mine is the one that keeps producing.

Designed for High-Production Mining Operations
Whether your operation requires hundreds of cubic yards of paste per hour or a custom-engineered solution for a specialized application, CMQ Engineering designs systems capable of supporting demanding production schedules.
Our paste backfill plants are available in capacities from 300 to 600 cubic yards per hour, providing the throughput needed for modern underground mining operations.
Higher production means:
- Faster stope filling
- Reduced production bottlenecks
- Improved mining cycle efficiency
- Increased ore recovery opportunities

Superior Mixing Produces Superior Paste
At the heart of every paste backfill plant is one critical process: Mixing.
Uniform binder distribution directly affects paste strength, pumpability, pipeline performance, and long-term reliability.
CMQ Engineering’s extensive experience in industrial batching and high-performance mixing enables us to produce consistently homogeneous paste that performs predictably underground.
The result is a paste that pumps efficiently, cures consistently, and helps support safe mining operations.

Complete Plant Integration
One Engineered System. One Trusted Partner.
A paste backfill plant isn’t simply a mixer. It’s an integrated production system. CMQ Engineering designs every component to work together as one coordinated operation, including:
- Tailings handling systems
- Binder storage
- Material weighing
- High-accuracy batching
- Industrial mixing
- Water dosing
- Plant automation
- Production reporting
- Pump feed integration
By engineering the complete process — not simply individual pieces of equipment — we help eliminate bottlenecks while simplifying operation, maintenance, and future expansion.
Built for the Real World
Mining environments are among the harshest industrial settings anywhere. Equipment must perform day after day under abrasive materials, demanding production schedules, and challenging operating conditions. That’s why CMQ Engineering designs equipment with durability, serviceability, and long-term reliability in mind. Because equipment that’s easy to maintain is equipment that spends more time producing.
Automation That Gives You Control
Every CMQ Engineering paste backfill plant includes sophisticated plant controls with comprehensive production reporting. Operators can monitor:
- Production rates
- Batch records
- Material usage
- Binder consumption
- Recipe management
- System diagnostics
The result is better operational visibility, improved quality control, and valuable production data for mine management.
Mobile or Permanent Installations
Every mining operation has unique requirements. CMQ Engineering offers both stationary and mobile paste backfill plant configurations to accommodate a wide variety of applications, production capacities, and project lifecycles. Whether you’re developing a permanent underground operation or supporting a temporary mining project, we’ll engineer a solution that fits your operation.
