One component to an operation that often is overlooked but critical to moving aggregate is rubber. Rubber keeps material bouncing along in the form of conveyor belts and off-road tires. Here is a much deserved tribute to the neglected compound and related products that many take for granted.
RUBBER IS AN OVERLOOKED, BUT CRITICAL, MATERIAL USED TO BOOST THE BOTTOM LINE
Douglas Manufacturing's return roll guard Guardian3 has a 180-degree UHMW cage that provides pinch-point protection and catches the roll if it breaks away from the brackets. The UV stable cage has increased slot sizes and new self cleaning slots in the bottom to resist material build-up inside the guard. The company says the UHMW will not corrode and resists impact damage and wear from abrasion. A side shield encapsulates the roll and snaps into place to secure the provided heavy-gauge steel mounting brackets. It is compatible with CEMA B, C, D & E idlers 4-, 5-, 6- and 7-inch-diameter rolls with 1Ω-inch and 4Ω -inch drop brackets.
Two options are provided for mounting: galvanized-steel nuts, bolts and washers and optional pin and clevis for use on the back side of the roll. The end shield is snapped in place using the provided hanging brackets and integrated mounting system.
Superior Industries Slide-Pac conveyors are designed with a roll-style slide-off system for the unloading of the top two conveyors from the bottom trailer unit. From start to finish, the entire unloading process takes just minutes to complete, the company says. The three-in-one conveyor system is available in lengths of 60 feet, 70 feet and 80 feet for up to 240 feet of total conveyor length in one load. The trailer unit can be raised to a 14-foot discharge height, is equipped with air brakes, a fifth wheel hitch and travel lights. Superior manufactures its 70- and 80-foot units with tandem axles.
The ASGCO wash box is installed as a secondary belt cleaner and is designed to work on the return side of the conveyor belt. Each fully enclosed, galvanized or stainless steel box is equipped with a combination of pressure rollers, spray bars, Razor-Back belt cleaners and dry-wipes. The nozzles apply a low-volume, high-pressure water spray, which softens the carry-back and provides lubrication to maintain cleaning pressure. The wash-box system is fully enclosed to contain the waste fluid, which can be recycled or drained into the plant pump. Included in the box are two removable service doors on each side, along with a wash-down hose, for access and maintenance of the cleaners and sprays.
Schenck Process has five different belt conveyor types from simple frames consisting of channels tied and braced with a steel deck plate between the top and bottom run of belt to frames with double walkway galleries are part of the standard belt conveyor offerings. Modern, synthetic fibers used in the belt construction resist stretching, permitting high belt speeds with capacities from 100 to 5,000 tons per hour.
New Partek Wrap from Parker Hannifin is an abrasion-resistant sleeve that can be added after a hose has been installed. Partek Wrap also can be used to bundle multiple hoses/cables together or to protect cylinder rods from damage and contamination. The company says they are lightweight and flexible. Partek Wrap is made from a urethane-coated 1050 ballistic nylon. It comes on a 50-foot roll and its tight weave pattern prevents the fabric ends from fraying when cut. Partek Wrap cuts with household scissors. It has an ambient temperature range of -60∞F to 200∞F and is available in four sizes.
