POLYGON MACHINE
MOBILE CEMENT SILO ON WHEELS
Polygon Machine’s mobile cement silos combine the convenience of trailer-mounted transport with the capacity of a fixed storage plant. These wheeled silo units allow contractors to store bulk cement securely and move it on demand, essentially acting as “cement storage trailers” for any site. Built from thick anti-corrosion steel, each cylindrical silo body protects cement from moisture and contamination, while integrated flow features (cones, aeration pads and vibrators) ensure continuous discharge. Unlike stationary tanks, a Polygonmachine wheeled silo can be dragged into position, leveled, and commissioned in minutes without a foundation. In practice this means sites get cement on tap immediately – boosting productivity and reducing labor. Modern mobile silos include all the technology of a bulk plant (blowers, valves, gauges, filters) in a compact, mobile package, setting a new standard for on-site storage.

OVERVIEW & KEYFEATURES
Polygon Machine’s Mobile Cement Silos are designed to provide high-capacity, portable cement storage solutions that combine the performance of stationary silos with the convenience of trailer-mounted mobility. These silos are perfect for modern construction sites that demand flexibility, fast setup, and reliable bulk cement handling.
High Capacity
Polygon Machine silos are offered in multiple sizes to match project needs. Typical mobile models range from a few dozen up to around 150–200 metric tons of cement (roughly 20–150 m³ of material). The steel silo body (often 4–6 mm thick ST37 grade plate) holds the bulk material and tapers to a cone for positive flow. Heavy-duty frames and welded bases ensure each silo can reliably store large volumes for weeks at a time.
Mobility & Setup
Each silo mounts on a rugged frame with wheels or a towing hitch, plus built-in jacks or skids for leveling. No concrete pad or crane is needed – crews simply drive or lift the silo onto flat ground, engage the stabilizers, and it’s ready to use. Transport dimensions (typically ~3.8–4.0 m wide by ~5–6 m long) allow highway towing under 4 m height, then the silo is raised into ~12–15 m operational height for filling. This rapid setup (often under 30 minutes) avoids site delays.
Discharge System
A built-in pneumatic/screw conveyor system lets cement flow out smoothly. Standard configurations use a 7–10″ diameter screw conveyor powered by a ~5–10 HP motor, plus a linked blower/vane feeder for high throughput. This design provides full-cylinder discharge without bridging. Critical components (pressure-relief valves, rotary airlocks, pinch valves) keep the material flow steady and safe. Polygon Machine silos also include level indicators and alarms so operators always know the inventory.
Dust Collection & Environment
To meet environmental standards, each mobile silo is fitted with a dust-filter assembly on the top inlet. In practice this is a baghouse/cartridge collector (e.g. a ~250–500 m³/h AirMax system) coupled with automatic vibrators or blowers to purge the filters. All loading and discharge are enclosed, so airborne cement is captured and clean air is exhausted. Industry sources note that such silos “come with dust control features that keep the area clean and safe,” dramatically reducing health hazards and cleanup needs. By preventing spillage and emissions, Polygon Machine’s designs are inherently eco-friendly, complying with EPA and EU dust regulations.
MOBILITY & INSTALLATION
Polygon Machine’s mobile silos emphasize flexibility. Their wheeled chassis or sliding-skid design lets one truck tow the silo directly into position. Setup is straightforward: using a forklift, crane or truck, the silo is placed on firm ground, then the integrated jacks and anchor points are extended to level it. Installers then align the silo’s discharge spout with the plant or mixer inlet to avoid spillage. Once locked down, pneumatic fill hoses and electrical cables (pre-wired at the factory) are attached and the silo is ready. Industry guides confirm that with proper preparation this process can take “under minutes”. No civil foundation or crane rental is required – the steel base itself acts as the support pad, saving both time and cost (site prep is limited to a flat pad or simple cribbing). This “plug-and-play” ease means downtime is minimized when moving between work sites.
DISCHARGE SYSTEMS &CONTROLS
High-Capacity Discharge System
Each mobile silo includes a high-capacity discharge system. Typically, cement is metered out by a heavy-duty screw conveyor at the silo bottom.
For example, an exemplar design uses a 10″×17′ screw conveyor driven by a 5 HP motor and gear reducer. An upstream blower package (e.g. 60 HP vane feeder) pneumatically transfers cement into the silo during filling.
This dual screw/blower setup ensures blockage-free flow: if cement begins to bridge, internal air pads and vibrators activate to fluidize the powder. The result is a steady, controlled output – ideal for feeding batching plants or mixers continuously.
Electronics and Instrumentation
Electronics and instrumentation are factory-integrated.
A smart control panel (often Allen-Bradley or equivalent) with pre-mounted pushbuttons and gauges runs the silos. Operators can switch between manual or automatic modes, receive high/low level alarms, and monitor silo pressure.
Safety and Operational Features
Overfill sensors and relief vents prevent dangerous pressure buildup.
In practice, Polygon Machine silos match these specs: pressure safety valves and level-warning lights are standard. In short, the mobile silo functions like a fixed batch plant silo, but in a package you can drive.
DUST COLLECTION & ENVIRONMENTAL BENEFITS
An advantage of mobile silos is the environmental control they provide. Polygon Machine designs incorporate a baghouse dust collector on the fill port to trap fine cement dust. In use, the collector’s filter elements capture airborne particles from filling or internal aeration, then pulsate clean with vibrators. For example, one system uses an AirMax™ dust filter rated ~225–500 m³/h, with electric vibrators timed to clear the filter media. Industry reports emphasize that such silos make the site “cleaner and safer” by capturing dust at the source. This not only protects worker health but also ensures compliance with strict emission standards. Cleaner job sites mean less cleanup time and reduced waste. In fact, the “eco-friendly” aspect of mobile silos is often highlighted: by preventing spills and containing dust, they mitigate pollution compared to unconstrained loading methods. Because the silo sits on a rigid steel base, site preparation is minimal.
No drilling or concrete is needed, eliminating leachate risks or excavations. Some models even include steel skid beams so the unit can be slid on and off trucks directly. Combined with enclosed conveyors and filters, the entire system greatly cuts fugitive dust.Compared to bag dumping or tankers, these silos keep nearly all cement contained. The end result is a smaller environmental footprint — an important selling point for Polygon Machine in both U.S. and European markets.Because the silo sits on a rigid steel base, site preparation is minimal.

APPLICATIONS AND DEPLOYMENT
Global Deployment and Use Cases
Polygon Machine mobile silos have been deployed worldwide wherever on-demand cement storage is needed. In the United States, highway and road contractors use them to keep asphalt patching and concrete paving plants running longer between bulk deliveries. Fast-moving projects like new bridge decks or power plant sites leverage the silos to avoid batching delays.
Popularity in Europe
In Europe, where construction sites often move and available space is limited, low-profile mobile silos are especially popular. Polish and German contractors, for instance, use them on urban projects to keep delivery trucks off congested streets. Road builders in Scandinavia mount Polygon Machine silos on trailers to support cold-weather paving in remote areas. Across both regions, typical uses include remote residential developments, temporary airport expansions, and emergency repairs — anywhere that a fixed cement plant cannot be built.
Efficiency and Cost Benefits
By one account, a mobile silo can replace multiple truckloads of bagged cement in a single setting. Polygon Machine reports that customers in the U.S. Midwest and southern Europe have reduced material handling by ~30–50% after switching to silo storage. This yields faster work (continuous dosing instead of intermittent dumps) and lower unit costs. The combination of portability and capacity means operations in both short-term jobs and long-running projects benefit. In short, Polygon Machine mobile silos fit “the ultimate solution for mobile construction” as one manufacturer phrased it — freeing contractors from conventional supply constraints.
