Proper material flow in silos is important for more than just production schedules. Issues with material flow can cause increased stress on silo walls that may go beyond what the silo was designed to withstand. Not only does this cause cracking, spalling and possible wall separation, it can also lead to structural failure.
 
Silos that were initially designed with internal reinforcement sometimes face cracking or delamination of the concrete. When this is seen on the silo exterior, it is important to schedule a silo inspection as soon as possible. Such damages are often caused by overstressing of the horizontal reinforcing as a result of material flow issues.
 

What is silo post-tensioning?

Tension is a critical component in silo repair. If the silo is still structurally sound, certain damages caused by failing interior steel reinforcement can be repaired by post-tensioning. Post-tensioning silo repair uses high-strength post-tensioning strands that are placed around the exterior of the silo. These tensioned bands essential take over the structural support of the original internal steel by keeping walls sturdy against additional stress caused by asymmetric flow.
 
During this restoration process, a qualified engineer uses factors such as silo size, stored material weight and how the silo is used to determine tension specifications necessary specifications for wall reinforcement. After the strands are properly tensioned through a hydraulic process, steel lock couplers are positioned and tightened. Once completed, the tensioning assures that the silo can be safely used. Once the silo is restored through post-tensioning, it can then be returned to its actual load capacity.

Silo cleaning is an essential part of silo ownership. It also saves you money and maximizes production and profit. Avoiding compaction and hydration of material through regular emptying and cleaning keeps your silo in proper working order. When stored material becomes too compacted, it must be removed by a professional cleaning company. An efficiently working silo helps you meet production goals.
 
By removing material buildup, silos are returned to their original storage capacity, and material flow issues that can slow down production are corrected. Clogged or slow running silos are a problem that will interfere with efficiency and profitability. Material buildup deters the silo from reaching its full capacity. Once a silo begins to lose flow, this accelerates the buildup over time and can lead to additional blockages. Removing this buildup can also allow you to recover lost material. Our professional team maximizes the cost-effectiveness of your silo cleaning operations by supplying the necessary industrial vacuum truck services to meet the requirements of your situation.
 

The Boss - Silo Cleaning Techniques

Professional silo cleaning companies typically use a remote, dry cleaning system to remove stubborn material buildup. The most powerful system available in the U.S. is a unique clean-out head, The Boss, proprietary to USA Silo Service that is 65% more powerful than other pneumatic systems. By removing more material faster and more efficiently than any other clean-out method, including the whip system, The Boss accelerates the cleaning process. This minimizes downtime and time spent on-site, providing immediate cost savings.
 
The Boss is a unique clean-out head designed to accommodate variable attachments selected by our field crews to match the type of material being removed. Our silo cleaning technique includes operating in a systematic pattern within the silo to remove the toughest buildups.
 

The Takeaway

Regularly cleaning your silo can help keep it operating efficiently and limit potential liabilities. Regular cleanings also increase your silo's usable lifespan, minimize big-ticket repairs, and avoid more costly cleaning expenses. In addition, professional silo cleaning saves you time and money by removing buildup and recovering lost material.
 
USA Silo Service, Inc. is a silo and bin cleaning, bulk storage removal/clean-out and industrial coating corporation that has serviced the needs of the industry for almost thirty years. Our silo cleaning services have been successfully performed throughout the United States and Canada and have proven benefits for our customers. USA Silo Service also provides vacuum truck and material disposal services to assist in removing and relocating silo debris. Our professional team also responds quickly to emergency silo cleaning needs.

Jumpform silo construction is a newer construction method that has been used for the last 30 to 40 years. While it is a more economical solution to silo construction, the end result is also one of the strongest construction types available.
 
The system relies on a Jumpform machine, or rig, consisting of a form and scaffolding system. This reusable silo framework is set up in just a few days. The system is available in a variety of diameter sizes, from 10' to 65'. Once the desired diameter is selected, the system is assembled on site. Once in place, reinforcement steel is set, quality control is checked, and the inside form is created. Concrete is then poured into this frame in a slow, controlled process in 4' tall intervals until the desired height is reached.
 
The ability to ensure the quality of the reinforcement steel placement and equipment before pouring the concrete directly results in a high-quality concrete silo. Once completed, the silo will retain a grid-like pattern on the exterior where the form had been in place.
 
What makes Jumpform silo construction so economical? In addition to the reusable frame, the incremental schedule, rather than the continuous schedule used in Slipform construction, reduces costs by approximately 20%.
 
Additional benefits:
 
  • The construction process is not adversely affected by weather events. Since the silo is constructed in 4' segments, it is easy to halt construction and pick up where it left off.
  • The incremental process also allows staggered delivery of construction materials. This keeps the construction area smaller.
