Cleat specifications are a very important aspect of the conveyor productivity. The cleat style, height and spacing must be matched with the material type, length and weight to ensure proper performance.
The cleat style can greatly impact the effectiveness of the conveyor belt. There are several belt cleat patterns and styles.
- Chevron pattern cleats can help center the material while conveying up inclines. Chevron has a wide variety of patterns to meet material requirements. Some patterns include open chevron, close chevron, herringbone, u-shaped, cleat top and multi-chev patterns.
- Steep climb patterns (another form of a Chevron) are good for medium to steep inclines and metering material. Steep climb belts also allow for the use of standard drum return rollers which minimizes maintenance and complexity.
- PVC & Rubber cleated belts are best suited for conveying material on inclines (no greater than 45 degrees) These are typically used for baler infeed conveyors and other applications where a deep burden depth is ideal.
- PVC & Rubber combination belts can be furnished with steel bar cleats and angle cleats. These belt and cleat combinations are used for conveying high tonnages of material for baler infeeds, sort station infeeds, and many other applications.
The height of the cleats can be used to create many outcomes. Cleat height can be determined to best convey small or large items with no tumble back (material rolling back down the incline causing a snowball effect). Cleat height (with conveyor incline angle) can also be used to intentionally cause tumble back for metering and singulation.
The spacing of cleats is imperative to ensure the desired tonnages and carrying of material. Example, if the OCC is 5’ long and the belt only has 24” cleat spacing the cleats will never be able to effectively grab the pieces of cardboard and they will slide back down the incline. If the application is to carry both small and large items belts can be furnished with alternating high and low cleats allowing for large gaps between the higher cleats but still carry material in shorter intervals.
