Stacker conveyors are used for stacking bulk materials into piles or creating stockpiles in industries like mining, quarrying, and material handling. We provide stacker conveyor for sale. The cost of a stacker conveyor can vary widely depending on various factors such as the conveyor's specifications, size, capacity, design complexity, brand, and the supplier or manufacturer.
Core Component of Stacker Conveyor
Each stacker conveyor is composed of essential components that ensure its reliability and efficiency in operation. Additionally, there are optional features designed to cater to specific user requirements.
- Fabricated Truss
Functioning as the conveyor's fundamental support structure, the fabricated truss plays a pivotal role in sustaining both the conveyor and the transported load. At SKE Industries, our trusses are meticulously engineered to endure diverse loads, including those induced by factors such as snow and wind, ensuring the stacker conveyor's robust and long-lasting performance.
- Frame-Mounted Idlers
These conveyor idlers play a crucial role in supporting the conveyor belt, maintaining its alignment, and facilitating the smooth transport of materials.
- Conveyor Belt
The conveyor belt serves as the dynamic platform for transporting materials. Its precise specifications are determined by the type and properties of the material destined for stockpiling.
- Head Section
Situated at the discharge point, the head section is where materials are unloaded from the conveyor.
- Drive Unit
Positioned at the head and connected to the discharge pulley, the drive unit supplies the necessary power for the conveyor's seamless operation.
- Tail Section
Functioning as the loading point for materials onto the conveyor belt, the tail section is a critical component.
Provided at the tail section and beneath the truss, skirting serves as a protective measure against any materials that might potentially fall from the conveyor. This feature enhances safety and containment during the material transport process.
Key Factors Influence The Cost of a Stacker Conveyor
- Conveyor Length and Size
Longer conveyors with larger dimensions generally cost more due to the increased material and manufacturing requirements.
- Capacity and Throughput
Conveyors with higher capacities and throughput capabilities typically have more robust designs and may involve larger components, affecting the overall cost.
- Material and Construction
The choice of materials for the conveyor structure, belt, and other components can impact the cost. High-quality materials and construction may result in a higher upfront cost but can contribute to durability and longevity.
- Automation and Features
Conveyors with advanced automation features, such as programmable logic controllers (PLCs), remote monitoring, and variable speed controls, may be more expensive.
- Mobility and Track Mounted
If the stacker conveyor is designed to be mobile or track-mounted for easy relocation, it may involve additional features that could affect the cost.
- Brand and Manufacturer
Established brands with a reputation for quality may have higher initial costs. However, they often provide reliable and durable equipment.
- Installation and Commissioning
Installation and commissioning costs may vary based on the complexity of the conveyor system and the services offered by the supplier or manufacturer.
- Customization and Special Requirements
If the stacker conveyor requires customization or has special design requirements to meet specific industry standards or regulations, it may affect the overall cost.
- Shipping and Logistics
The location of the manufacturing facility or supplier in relation to the installation site can impact shipping and logistics costs.
- Maintenance and Operating Costs
Consideration of long-term maintenance and operating costs is essential. Higher-quality components may result in lower maintenance costs over the conveyor's lifespan.
Evaluating the Cost of Stacker Conveyors
Gaining insight into the intricate dynamics of the components influencing the design and cost of a stacker conveyor is paramount. Let's delve into the impact of various considerations, ranging from the conveyor belt to the fabricated truss, on the design and, ultimately, the pricing of your stacker conveyor.
The optimal throughput (TPH) of your stacker conveyor, in conjunction with diverse material properties, dictates the width and speed of your conveyor belt. Key material properties include:
- Weight and density of the material
- Sharpness, granularity, and cohesion of the material
- Moisture and dust levels
- Belt troughing for efficient transport of materials with varying weights
Conveyor belts are available in widths ranging from 24 to 60 inches, and their construction (steel-belted or multi-ply) is contingent on the required load capacity. At SKE Industries, we estimate that the conveyor belt directly contributes to 3-5% of the total stacker cost, impacting various other machine specifications.
The fabricated framework supporting the conveyor system, inclusive of its drive, reducer, and idlers, is a pivotal factor. The structure's dimensions hinge on the elevation needed by the radial stacker, considering the maximum gradient for efficient material transport.
Conveyor structures can span 50-190 feet or more, achieving discharge heights of up to 65 feet with elevation grades of 18-20°.
For larger conveyor structures, truss construction is imperative, whereas smaller units may utilize 10×25 channel support structures. Notably, truss-built structures can cost approximately 20% more than channel-supported conveyors.
Irrespective of the construction method, the structure must effectively support the total weight of the equipment, the maximum rated load, and additional temporary loads from factors such as snow or wind.
The radial undercarriage, allowing the conveyor to rotate and discharge material along an arc, contributes to roughly 15% of the unit's cost. Larger conveyors with dedicated hydraulic rise systems can incur an additional 5-10% in costs.
Drive Unit and Reducer
The capacity and elevation of your conveyor system influence the required minimum size of the drive unit and reducer. Typically mounted at the discharge head and attached to the discharge pulley, these components collectively account for 7-10% of the total conveyor cost.
Other essential components that impact the unit's cost encompass:
- Frame-mounted idlers supporting the belt (approximately 7% of the unit cost)
- Head section, including discharge pulley, take-up screw, and additional idlers (5-10% of the total cost)
- Tail section, comprising hoppers and other loading and safety equipment (5-10% of the conveyor's price)
- Catwalks for accessing the conveyor belts on larger units
- Additional cleaners and skirting on the conveyor belt for dust control and worker safety
Mobile Stacker Conveyors
For those necessitating mobility, lightweight stackers can be supplied in a "street-ready" trailer format, towable to the site by a large truck or semi. Equipped with specialized folding mechanisms, brakes, and lighting, these units are typically pricier than similar-sized fixed conveyors.
Certain stacker conveyor systems incorporate a hopper mounted over the tail, holding the material before loading it onto the belt. The system can be engineered to load directly from an overland conveyor, belt feeder, transfer chute, or a Bobcat, based on user requirements.
For enhanced convenience and safety during operation and maintenance, a catwalk can be installed on one or both sides of the truss. SKE Industries is adept at customizing any stacker conveyor to meet specific operational requirements.
Given the various factors influencing the cost, it's advisable to consult with conveyor manufacturers or suppliers to obtain accurate and customized price quotes based on the specific requirements of your project. Additionally, comparing quotes from different suppliers can help you make an informed decision based on your budget and project needs.
