CAMBELT INTRNATIONAL

Cambelt International is a major supplier to the mining, chemical processing, cement, transportation, pulp and paper, metals, rubber, hazardous waste disposal, and many other industries whose standards demand the finest conveying equipment available.Cambelt, known for its patented one-piece flexible sidewall belting, continues its commitment to provide customers with products of superior quality.

In the past, these belts had to be molded and cured as three separate components, and bonded together to form the desired configuration.  Historically, the single biggest problem with this type of belt construction has been delamination or separation of the sidewall and/or cleat from the base belt when put under the stresses inherent in flexing around pulleys and being put under load. With Cambelt's massive 2500-tn rubber press, the base belt, fabric, sidewall, and cleat or nubs of the CamWall and CamFlex belting are molded and vulcanized together under high pressure so you can now Say Goodbye, to separation problems and, Hello to one piece molded construction.

Cambelt International's breakthrough in fully molded rubber belt technology now offers a solution to all these costly and aggravating problems: 

• No Glued On Sidwalls
• No Glued On Cleats
• No Down Time
• No Lost Production
• No Costly Repairs Due To Sidewall Separation
• No Need For 24 Hour Emergency Service

Automated For Dome Storage

PROVEN PERFORMANCE
Cambelt International's automated reclaiming systems are in operation in concrete storage domes located in the United States and in many other countries throughout the world. This proven reclaiming technology allows the dome and its superior strength to be more fully utilized. Used for storing large quantities of bulk materials, this unique storage concept provides many advantages.

• Lower investment
• Reduced manpower
• Lower operating costs
• Lower maintenance costs
• Full utilization of dome
• Full reclaim of material
• High reclaim capacity
• Blending of product
• Operational safety
• Minimal product degradation
• Simple foundation requirements

AUTOMATED RECLAIMING
The reclaiming system pulls the stored material to the center of the dome and discharges to the load-out conveying system through a 72" to 96 " diameter opening. Initially, the stored material will gravity discharge without the use of the screw, until it approaches its angle of repose. The reclaim screw is then lowered to the pile and the screw begins to cut into the pile, gently assisting the material to the discharge opening. Only during the final phase of reclaim of material from the dome does the 'open' screw perform all of the work of drawing the material to the discharge opening.

The Cambelt Reclaimer is best suited to operation in a steel-reinforced concrete dome.

 

 

 

 

 

 

 

Bulk Storage That Is - VERSATILE, EFFICIENT, & IMPERVIOUS TO WEATHER

Versatility

The most common structural shapes for bulk storage are either vertical silos or horizontal "flat storage". The versatility of concrete dome construction allows a shape that will meet the intended storage requirements, whether tall like silos, with a low profile like flat storage, or any shape in between.

Efficiency

Concrete domes offer several advantages over conventional silos or flat storage:

• Less costly to construct than silos
• More self-unloading than flat storage
• Rapid construction, regardless of the weather
• Simple foundation requirements
• Automated reclaim is simple to install and economical to operate
• Superior insulation qualities
• Condensation is virtually eliminated
• Maximum waterproofing
• Structures are adaptable for multiple use

Capacity

Concrete domes have been constructed to store more than 90,000 tons of bulk material.

Environmental Control

The superior qualities of concrete domes are immediately evident in any setting where it is important to control temperature, humidity or air exchange.

Many bulk-stored products-including most fertilizers-are adversely affected by moisture. The concrete dome's single-ply roof membrane and insulation envelope assure water tightness, and virtually eliminate condensation. The insulation also prevents temperature cycling, which can cause product degradation.

The high-density shotcrete is fireproof, and extremely resistant to corrosion.

Filling and Reclaim of Concrete Domes

Concrete domes display great flexibility in both filling and reclaim methods.

Because a dome is typically filled by conveying material above and dropping it through one or more fill openings, product can be piled high against the walls. This means that a higher percentage of the dome's volume is utilized than is the case with flat structures, resulting in a correspondingly lower cost per ton of storage.

The Cambelt Radial Reclaimer

The Cambelt radial reclaimer, built by Cambelt International, is a simple, effective mechanical reclaim system that has been developed to take advantage of the dome's superior volume utilization and structural strength. The equipment occupies only a fraction of the interior space taken up by other mechanical reclaim systems, while allowing the automated extraction of virtually all of the product stored. The reclaiming equipment is designed to allow the dome to be completely filled, burying the reclaim equipment, and allowing maximum use of interior volume.

Service Access

Access for service of automated equipment is normally through a drive-in entrance. This entrance allows the use of front-end loaders as an auxiliary reclaim method. However, service access can be through an opening at the dome's apex, or anywhere else on the structure, as design and functionality requirements dictate.

Conveyor Support

The inherent strength of concrete domes also allows heavy loads from conveyors to be supported on top of the dome. As much as 175,000 lbs. (80 tons) of conveyor loads have been supported on the apex of the concrete domes. The dome's compact shape and high internal volume utilization mean that conveyors can be shorter than those used with more conventional structures. Another significant saving results from the absence of many of the structural supports commonly used with conveyors.
