Critical Conveyor Components
Idler rollers, belt won’t freeze
The Standard Style A-1 Belt Conveyor Hoods from Stephens-Adamson Conveyor cover and protect conveyor material from being windblown and exposed to moisture as well as protecting the belt and idlers. The cover section, which is supported on bands of heavier-gauge steel or aluminum, also protects the belt from being dried out by the sun and prevents idler rollers and the belt from freezing. The support bands bolt directly to the foot brackets, which are bolted to the top of channel stringers or top chords of truss frames.
According to the manufacturer, this is a simple design that lowers the cost and time of constructing it in the field. The hoods consist of cover sections that are supported on bands spaced at 4-foot centers, and the total length of the hoods should be in multiples of the same length. However, if the total required length is not in this spacing, a cover section can be custom cut in the field and can be secured to the support band by field drilling for self-tapping screws.
The steel specifications include 22-gauge cover sections, 12-gauge support bands up to 36-inch belt width, 10-gauge support bands for more than a 36-inch belt width, and 3/16-inch steel foot brackets, and a retaining bar. Belt widths in stock are available in 18-, 24-, 30-, 36-, 42-, and 48-inch increments. Optional aluminum choices include 40-inch thick hood material and 190-inch thick foot brackets and support band.
Ensure uniform blade contact
The Eliminator H-Type conveyor belt pre-cleaners from Flexible Steel Lacing Co. (Flexco) strip away carryback residue at the head pulley to keep more material in the product stream. The belt pre-cleaners are independent, segmented blades offered in two styles for both mechanically fastened or vulcanized belts, and self adjust to the irregular contours of belt surface wear patterns to maintain efficient cleaning throughout the life of the blades and avoid the need for frequent retensioning.
The cleaner automatically ensures that there is uniform blade contact across the belt by keeping each blade segment individually under constant pressure of a pre-tensioned rubber cushion. It is intended for installation with blade tips contacting the belt at a point 15 degrees below the head pulley’s centerline, offering a compact design that allows for mounting either on the conveyor frame or inside nearly any discharge chutes. Any tension adjustments that are needed can be performed from the side of the conveyor or from the outside of the chute.
Eliminates stops and lockouts
InterSystems’ RS Mid Belt Sampler for sand and other aggregates material is designed to take representative samples up to 4 inches from moving belts. A rotating scoop makes a pass at pre-determined intervals across the moving belt taking the sample. The sample is then deposited into a gravity side chute for delivery to a collection system.
According to the manufacturer, the sampler eliminates the need to have an individual assigned to the sampling process, time-consuming production stops and lockouts, and wear and tear caused by frequent stops and starts. The sampler meets ASTM specifications for automatic sampling. The power requirements are an electric 110-volt single-phase control; one-phase and three-phase motors are available in 3 to 15 horsepower motor drives.
