When designing and purchasing a spiral gravity chute, several interacting factors goes into the design of them. These design factors include flow rate, pitch, diameter, material, intended use, and environment. How do you choose the correct spiral gravity let down chute for your product? You test it. And, you test it again. Testing on spiral gravity chutes is very important because all products flow down differently. So come to Astro and experiment on our three samples, here at Astro in Hanover, MN. We would love to assist you in the right design because we care!

Testing the Flow Rate, Pitch and Diameter

It is important to know what flow rate you are trying to achieve. This is in order to design a spiral that can achieve it. Therefore, how your product behaves sliding down the chute is the biggest influence to take into account. The whole system is designed around this key element. The required pitch must be finessed to achieve the desired amount of flow that is needed, given the diameter of the chute.  The flow rate is the function of the width, and the pitch you can get on it.

The right pitch is needed for your product to flow faster, but at a safe speed for minimal breakage of the items. This pitch has much to do with how a flight is stretched. The more you stretch it, the more you get a larger pitch.  However, there is a limit to how much a given size flight can stretch.

Spiral Gravity Chute Material

Our spiral chutes are made with either stainless steel or mild steel. It depends on the intended use and environmental factors, of course.  Do you require food grade vs non-food grade material? Plus, consider temperature and atmosphere when choosing the material and finish.

Common Products to Test on Spiral Gravity Chutes

• Raw and roasted coffee beans
• Peanuts, cashews, nuts & seeds
• Fertilizer
• Packages
• Snacks & candy
• Crackers & cookies
• Dry pasta
• Cereals
• Grains
• Frozen prepared foods, i.e. frozen burgers
• Pet food & animal treats
• Airport baggage handling
• Parcel handling

Collaborative Design on Chutes

Designing spirals is not an exact science. That&#;s why we&#;re here to assist you. All our spiral chutes are customized and fitted precisely to each unique environment and specification. Our team collaborates with our customers on design, fabrication, and implementation. Plus, there are virtually no limitations on the length of our spirals.  However, maximum length of a spiral chute in &#;one piece&#; is 40&#;.

Choosing the Right Conveyor System: A Comprehensive Guide

--

When it comes to transporting materials efficiently, conveyor systems are crucial in various industries. They save time, reduce labor costs, and streamline operations. With many options available, choosing the right conveyor system can be daunting. Here&#;s a detailed guide to help you navigate through your choices, focusing on flexible gravity conveyor conveyor systems.

Telescopic Conveyors

Telescopic conveyors are a versatile solution for loading and unloading goods. Their extendable and retractable design makes them ideal for truck loading and unloading operations.

• Functionality: Telescopic conveyors can extend and retract, allowing for easy alignment with different truck sizes and cargo types. This flexibility reduces manual handling and speeds up loading and unloading processes.
• Applications: Commonly used in warehouses, distribution centers, and shipping docks, these conveyors can handle a range of products, from boxes to pallets.
• Manufacturers: Several manufacturers offer high-quality telescopic conveyors, ensuring durability and reliability. Companies like [Manufacturer A] and [Manufacturer B] are known for their robust designs and customization options.

Benefits:

• Reduces labor costs by minimizing manual handling.
• Enhances efficiency in loading and unloading operations.
• Can be easily adjusted to different truck sizes.

Gravity Conveyors

Gravity conveyors utilize the force of gravity to move products along a sloped surface. They are often employed in situations where powered systems aren&#;t necessary or practical.

• Types: There are various types of gravity conveyors, including:
• Roller Conveyors: Ideal for moving cartons and pallets.
• Skate Wheel Conveyors: Suitable for lighter items and easier maneuvering.
• Pallet Conveyors: Designed to handle heavy loads, including pallets and crates.
• Materials: These conveyors can be made from various materials, including stainless steel, which is preferred for its durability and resistance to corrosion.
• Cost: Gravity conveyors are typically more affordable than powered systems. Prices vary based on material and design but generally offer a cost-effective solution for moving goods.

Benefits:

• Low maintenance and operating costs.
• Simple design leads to easy installation and adjustment.
• Suitable for a wide range of applications and industries.

Spiral Conveyors

Spiral conveyors are designed to move products vertically or horizontally in a compact space. They are particularly useful in situations where floor space is limited.

• Types: Several designs include:
• Vertical Spiral Conveyors: Ideal for elevating products between floors.
• Spiral Roller Conveyors: Combine vertical movement with horizontal transport.
• Spiral Chute Conveyors: Use gravity to move items gently along a spiral path.
• Design Considerations: When choosing a spiral conveyor, consider factors such as the product size, weight, and the speed required. The design must accommodate the specific needs of the operation.

Benefits:

• Efficient use of space due to their compact design.
• Ideal for continuous operations and high throughput.
• Reduces the need for additional floor space and handling.

Modular Conveyors

Modular conveyors offer flexibility and customization in conveyor systems. These systems are designed using interchangeable modules, allowing for easy reconfiguration and expansion.

• Types:
• Plastic Modular Belts: Offer durability and ease of cleaning.
• Modular Belt Conveyor Systems: Allow for customization in length, width, and configuration.
• Expandable Conveyor Systems: Can be extended or retracted to fit different needs.
• Manufacturers: Leading companies such as [Manufacturer C] and [Manufacturer D] provide modular conveyor solutions with various customization options.

Benefits:

• High adaptability to changing needs and layouts.
• Easy to maintain and repair due to interchangeable parts.
• Can be tailored to specific operational requirements.

Key Considerations

When selecting a conveyor system, consider the following factors to ensure you choose the best option for your needs:

• Load Capacity: Ensure the conveyor can handle the weight and volume of products.
• Speed and Efficiency: Choose a system that meets your operational speed requirements.
• Space Availability: Select a design that fits within your operational space constraints.
• Maintenance Needs: Opt for a system with low maintenance requirements to reduce downtime.

Conclusion

Choosing the right conveyor system depends on your specific needs and operational requirements. Telescopic conveyors are excellent for dynamic loading and unloading, gravity conveyors offer cost-effective transport solutions, spiral conveyors maximize space efficiency, and modular conveyors provide flexibility and customization. By understanding the benefits and applications of each type, you can make an informed decision that enhances your operational efficiency and productivity.
