Industrial Silo Cleaning Tools: The Right Equipment for the Job

Choosing the right industrial silo cleaning tools is essential for safe and efficient maintenance. Each project varies based on several factors, including silo size, shape, material type, and discharge system. Understanding these factors helps streamline the cleaning process while preventing damage and costly delays. Moreover, it ensures that the cleaning method aligns with the specific needs of each silo.

Key Factors Affecting Industrial Silo Cleaning Tools

Silo size: Cleaning methods differ depending on the silo’s diameter and number of discharge points. Larger silos need more advanced industrial silo cleaning tools than smaller ones. Therefore, it’s important to assess the silo size before selecting equipment.
Silo shape: The bottom design and internal structures affect the flow characteristics. Flat-bottom silos require different cleaning techniques than those with steep cone angles. As a result, understanding the silo shape helps determine the most effective approach.
Material type: Cleaning hydrated cement requires different techniques than cleaning grain or pet food. Consequently, the type of stored material directly influences the cleaning strategy and the necessary industrial silo cleaning tools.
Discharge system: How the loosened material exits the silo depends on whether the system uses air slides, conveyor belts, truck loadouts, or free-flow setups. Thus, understanding the discharge system ensures efficient material removal.

For over three decades, Mole•Master has cleaned silos worldwide. Our success comes from understanding which tools work best for each project. Knowing the process helps silo owners address concerns early during project planning. Furthermore, it allows for better resource allocation and cost management.

Interior Industrial Silo Cleaning Tools

Interior cleaning focuses on removing non-flowing or contaminated material from a silo. It may also involve clearing rust, construction debris, or oil residue from manufacturing. Excessive buildup can weaken the structure, leading to potential failure. Moreover, proper cleaning prevents contamination when switching stored materials.

Failure to clean the interior can reduce storage capacity, spoil products, and cause production delays. Therefore, regular cleaning is vital for maintaining operational efficiency. Additionally, it supports product quality and extends the silo’s lifespan.

OSHA-Compliant Confined Space Entry

The most basic cleaning method involves trained professionals entering the silo to remove blockages, dust, or contaminants manually. Workers use harnesses, retrieval systems, and suspension gear to ensure safety. Since confined space entry can be hazardous, expertise is crucial for this approach. Therefore, professional oversight is essential.

To enhance safety, Mole•Master prioritizes non-entry cleaning whenever possible. Our proprietary equipment reduces the need for confined space access, making the process safer and more efficient. For more information on confined space safety standards, visit OSHA’s official site.

Whip Machines: Junior 360™

Pneumatic or hydraulic whip machines are ideal for silos with buildup and an existing flow channel. The cleaning head, powered by compressed air or hydraulics, features two to four whips or chains. Operators control the whips from outside the silo, reducing the need for confined space entry. As the head spins, it dislodges material from the walls while lowering from the roof.

Mole•Master has manufactured the Junior 360™ for 29 years. This system works for silos of varying sizes and configurations. We also offer explosion-proof options for hazardous environments. Learn more here.

CO₂ Blasting: Safe-T-Shot™

CO₂ blasting breaks up material using a powerful carbon dioxide stream. This method works well for hardened materials like hydrated lime, coal, and compacted grain. The process involves sealing liquefied CO₂ inside a heavy-duty steel tube. An electrical current activates a sealed generator, heating the liquid and converting it into gas. As a result, the gas expands rapidly, exiting the tube at pressures exceeding 25,000 psi.

Mole•Master uses the trademarked Safe-T-Shot™. Unlike explosives, this system is safe for dusty, combustible environments and won’t damage or contaminate silo linings. Moreover, it offers a reliable solution for challenging cleaning projects.

Drills and Portable Auger Systems: Arch•Master™

For silos with arched or bridged material, a drill or auger system offers the best solution. Arching occurs when material builds up, blocking discharge without a flow channel. In such cases, drilling through the blockage becomes necessary before using other cleaning tools. Therefore, selecting the right drilling equipment ensures successful cleaning.

Mole•Master recommends the Arch•Master™. This miniaturized rock drill creates flow channels up to 152 feet (45 meters) deep. Its high-torque, variable-speed hydraulic power head pairs with heavy-duty auger bits to drill holes up to 10 inches in diameter. Consequently, it ensures efficient material removal while preserving silo integrity.

Efficient Material Removal with Industrial Silo Cleaning Tools

Vacuum Trucks and Industrial Vacuum Systems

Using a silo’s discharge system for cleanout isn’t always ideal. Loosened material may not meet quality standards or flow properly. In other cases, the discharge rate may slow the cleaning process, increasing costs. High-volume vacuum trucks address these challenges effectively. Moreover, they streamline material removal, saving both time and money.

Mole•Master relies on the UltraVac HVV-4915, the T-475, and the electric HiVac 250 for most industrial vacuum applications. In addition, we use the DK Vacuum Transfer Unit for projects involving grain or plastic pellet removal. As a result, material removal becomes faster and more efficient.

Hydroblasting and Power Washing

While many projects benefit from dry cleaning methods, some require high-pressure water to remove stubborn residue. Hydroblasting tools range from handheld nozzles to remote-controlled machines. The appropriate tool depends on the material and the pressure needed for effective cleaning. Therefore, choosing the right hydroblasting equipment ensures optimal results.
