The Portabatch is a very robust plant and highly regarded in the construction and mining industries worldwide.  There have been innovations and upgrades for performance and safety over the years which has been recommended by the people on the ground using CMQ’s mobile plants.  This makes them easier to operate, set up and maintain.  A unique feature on the CMQ Portabatch and Mobile Silos is the shut-off plate above the horizontal screw.  This allows you to empty the screw and leave some product in the Silo prior to travel which is a great advantage at the end of a project.

CMQ delivers world class innovation and design.

We have designed and manufactured this state of the art plant which is currently being installed in Idaho

Features:

• The Tailings Hopper and Conveyor will feed product into our Pugmill.
• The Silo will discharge into the Loss of Weigh Hopper.
• The Paste Hopper and Screen will receive, regulate and condition the paste material
• Completely automated paste control

CMQ has proudly designed and manufactured its first 100 Tonne (GP cement) Mobile Silo.

The discharge rate is 105 tonnes of GP cement per hour.

As with all our Mobile Silos:

• The plant can be towed by a standard prime mover without an escort
• The sliding shut off plate above the horizontal screw allows the screw to be emptied for transport and maintenance with product remaining in the silo
• The plant is wired to Australian Standards, using steel wire armoured cable,

What are Cement Storage Silos?

Cement silos are specialised storage structures designed to hold bulk powdered materials such as cement, fly ash, or lime. They play a central role in batching plants, quarries, and large-scale construction projects by protecting stored products from moisture and environmental exposure. Well-executed cement storage silo design helps preserve product integrity, reduces operational downtime, and ensures a consistent feed into mixers or processing systems.

Without properly designed silos, materials can clump, degrade, or fail to discharge effectively, leading to higher maintenance costs and production inefficiencies. This makes silo design a crucial consideration for plant operators.

Why Cement Storage Silo Design Matters

The purpose of a silo goes beyond containment. A well-engineered design should:

• Maintain the quality and flow characteristics of the stored material.
• Reduce the risk of blockages and downtime.
• Allow safe filling and discharge under variable load conditions.
• Meet compliance standards for structural integrity and workplace safety.

When assessing cement storage silo design, operators must consider how the system integrates into the wider plant, from conveyors and batching equipment to dust collection systems. Poor integration can create bottlenecks that slow production and increase costs.

Important Factors in Cement Storage Silo Design

Several key factors determine whether a silo will operate effectively across its service life:

1. Capacity and Dimensions

Sizing a silo correctly is the foundation of good design. Undersized silos can cause supply interruptions, while oversized silos may add unnecessary cost. Capacity should align with batching cycles, supply logistics, and peak production demands.

2. Structural Integrity

Silos must be engineered to withstand external loads such as wind and seismic activity, as well as internal pressures from filling and discharge. Compliance with local design codes and safety standards is essential.

3. Flow Efficiency

Material flow is at the heart of cement storage silo design. Hoppers, cone angles, and aeration systems must be optimised to prevent bridging, rat-holing, or inconsistent discharge rates. Flow aids such as fluidising pads or vibration systems are often incorporated.

4. Environmental Protection

Because cement and other powders are highly sensitive to moisture, silos should incorporate weatherproofing, appropriate sealing, and efficient dust collection systems. This protects product quality and minimises environmental emissions.

5. Safety Features

Safe access ladders, platforms, pressure relief valves, and monitoring systems should all form part of modern silo construction. These features reduce risks during filling, inspection, and maintenance.

6. Integration with Plant Systems

The best cement storage silo design considers how the silo interacts with feeders, weigh hoppers, and pneumatic transfer systems. A well-integrated silo keeps materials moving smoothly through the plant, supporting higher productivity and lower maintenance costs.

Choosing the Right Partner

Selecting experienced silo manufacturers ensures these design factors are built into your project from the outset. With more than 50 years of engineering experience, CMQ Engineering is a trusted mining engineering company delivering turnkey solutions across concrete, quarrying, mining, and agricultural sectors. From design and fabrication to installation and commissioning, we ensure silos and supporting systems are tailored to the unique needs of Australian operations.
