Air Cannon Valves & Accessories

In bulk material handling systems such as cement, mining, quicklime, or chemicals, blockages and high temperatures in silos, rotary kilns, and preheater towers are constant challenges. To enhance the reliability and efficiency of Air Cannon systems, manufacturers have developed a range of specialized Air Cannon Valves and accessories, helping to improve safety, reduce costs for air cannon operations, and optimize performance.

Air Cannon Valves & Upgrade Accessories

Below is a selection of air cannon valves as well as upgrade and replacement accessories for air cannon systems.

1. Thermo Safety Shield

What is the Thermo Safety Shield?

• The Thermo Safety Shield is a sliding gate installed between the air cannon discharge valve and the mounting flange. It is designed to protect workers during maintenance in high-temperature environments such as preheaters, clinker coolers, and other hot spots in the production line.

Technical Specifications:

• Compatibility: Compatible with air cannons featuring 4-inch and 6-inch discharge diameters.
• Safety Construction: Heat-resistant steel structure equipped with safety bars and lock-out/tag-out capabilities.
• Mechanism: Mechanical sliding mechanism, requiring no external power source.
• Installation: Simple connection between the valve and flange without affecting the original structure.

Advantages:

• Allows for safe air cannon maintenance even while the equipment is active and hot.
• Prevents leakage of hot gases, toxic fumes, and protects against radiant heat.
• Easy-to-install design, ensuring convenient operation for maintenance personnel.

Applications:

• Air Cannon systems operating in high-heat zones such as: Clinker silos, cement rotary kilns, preheater towers, quicklime processing, and chemical plants.

2. Piston Return Reservoir – Tornado Air Return Reservoir

Concept:

• An air return reservoir designed for Tornado Air Cannons, helping to increase refill speed and reduce compressed air consumption while maintaining maximum blast force.

Technical Specifications:

• Retrofit Design: Integrates a canister piston directly into the Tornado valve.
• Automatic Closure: After discharge, the piston automatically closes the valve at approximately ~50% of the tank volume (preserving the remaining pressure).
• Cycle Optimization: Optimizes the refill cycle without compromising peak pressure.

Advantages:

• Reduces Air Consumption: Cuts compressed air usage by up to 50%.
• Faster Cycle Times: Increases continuous firing speed, enhancing overall system efficiency.
• Cost Savings: Significantly lowers compressed air operating costs.

Applications:

• Tornado Air Cannon systems installed in raw material silos, coal chutes, and ore hoppers.

3. XHV Retrofit Valve – High-Performance XHV Upgrade Valve

Concept:

• A retrofit valve kit designed to upgrade existing Air Cannon systems using Extra-High-Velocity (XHV) technology. Compatible with various air valve systems, it is engineered to increase blast force and reduce maintenance requirements.

Technical Specifications:

• Short Stroke Design: Features a short 16 mm (5/8-inch) piston stroke requiring no lubrication.
• High-Temp Seals: Utilizes a Nylatron® polymer seal capable of withstanding temperatures up to ~200°F.
• Installation: 8-bolt “bolt-on” design, complete with gaskets and necessary mounting hardware.
• Compatibility: Compatible with 2”, 4”, and 6” discharge outlets.

Advantages:

• High Output & Durability: Delivers a powerful air pulse with a service life rated up to 2 million cycles.
• Simple Retrofit: Easy installation that allows for upgrades without replacing the entire tank/system.
• Cost-Effective: Reduces maintenance costs and significantly enhances system reliability.

Applications:

• Upgrading air cannon systems in cement plants, recycling facilities, coal handling, and chemical plants.
• Ideal for upgrading older XHV valves while retaining the existing air tanks.

4. Tornado Exhaust Upgrade Kit

Concept:

• A retrofit kit designed to convert standard XHV valves to the Tornado exhaust valve system, featuring a positive-acting valve mechanism. This upgrade enhances response speed, improves safety, and boosts overall performance.

Technical Specifications:

• Components: Includes a piston, spring, and the Tornado exhaust valve assembly.
• Activation Mechanism: Requires a secondary positive pressure signal to trigger the discharge (blast).
• Sizing: Available in 3 size options compatible with various XHV valve models.

Advantages:

• Increased Power: Boosts blast force by approximately ~20%.
• Reliability: Provides rapid response and eliminates accidental firing (misfires) caused by pressure drops.
• Remote Operation: Allows the control solenoid to be positioned up to ~60 meters (200 ft) away, keeping sensitive electronics out of high-heat zones.
• Flexibility: Increases flexibility in the layout of the control system.

Applications:

• Used for existing Tornado systems or retrofitting XHV systems requiring upgrades for enhanced blast efficiency and safety.
• Particularly effective in cement, coal, and chemical processing applications.

General Features of Air Cannon Replacement & Upgrade Accessories

To maintain optimal performance and minimize downtime in bulk material handling systems, Focus offers a comprehensive portfolio of specialized replacement and upgrade accessories for Air Cannons. These solutions are designed to not only enhance operational efficiency but also simplify maintenance procedures.

• Replacement Valves: Designed for rapid installation, these blast valves allow for quick interchangeability between product lines. The average replacement time is approximately 10 minutes, significantly minimizing production interruptions.
• Air Cannon Controllers: Supply power to solenoids and enable precise control over air discharge sequencing. The control system can simultaneously operate up to 10 air cannons, ensuring synchronization and high performance.
• Smart Nozzles: An innovative solution that eliminates the need to cut holes or break through refractory brick or silo walls to replace worn nozzles. This smart design results in significant savings in labor costs and maintenance time.
• 360° Retractable Nozzles: Developed for high-temperature applications such as preheaters and clinker silos. The nozzle fully retracts after firing, protecting it from the harsh environment, extending equipment life, and reducing mechanical wear.
• Thermo Safety Shield: A safety accessory designed to protect personnel in high-temperature environments. It allows for air cannon maintenance without system shutdown while effectively preventing the leakage of hot gases and toxic fumes.
