A new open-chute, high-capacity dumper, the High-Lift Bin Dumper, hydraulically raises and dumps mobile bins (weighing up to 3,000 pounds) into hoppers, which then feed integral flexible screw conveyors.
The bins are rolled into a three-sided pen; from there, lifting tongues (centered within casters) raise and seat the bins’ rims against grates which, along with paneled side bracing, steady the bins during the dumping cycle and then direct the materials’ discharge paths.
Then, the system automatically lifts mobile bins at variable heights (up to 10 feet above floor level), opens receiving hoppers’ gate-style lids, dumps all of the bins’ contents into the hoppers and then returns the bins to the plant floor once the hopper lids close.
Company Product Description
A new open-chute High-Lift Bin Dumper from Flexicon hydraulically raises and dumps mobile bins into a hopper that feeds an integral flexible screw conveyor operating under loss-of-weight control.
Bins weighing up to 3000 lbs (1350 kg) are rolled into a three-sided pen, where a lifting tongue centered inboard of the casters raises and seats the rim of the bin against a grate which, together with paneled side bracing, steadies the bin during the dumping cycle, and directs the discharge path of material.
The system automatically lifts a mobile bin at variable heights up to 10 ft (3 m) above floor level, opens the gate-style lid of the 60 cubic foot (1.7 m3) capacity receiving hopper, dumps the entire contents of the bin into the hopper, and returns the bin to the plant floor as the hopper lid closes, isolating the material from the plant environment.
A laser curtain prevents operation until the bin is secured and the area cleared, eliminating the need for a safety cage with interlocked doors.
The design of the receiving hopper includes a vibratory “live” bottom to promote the uninterrupted passage of non-free-flowing material through flexible downspouting into the material charging area of a flexible screw conveyor. This conveyor stops and starts based upon loss-of-weight signals from load cells to the system, delivering the desired weight of material to be transferred.
The unit is constructed of stainless steel finished to food, dairy, pharmaceutical or industrial standards, and is also available in carbon steel with material contact surfaces of stainless steel.
