The KHODIYAR INFRATECH Jumbo Bag Unloading System, also known as Jumbo bag dischargers and super sack unloaders are specifically designed to provide an easy, clean and economical way to discharge the entire contents of bulk and semi-bulk bags, especially when the material is less than free-flowing. Jumbo bags can be placed in the Jumbo bag unloader by fork lift, hoist or crane from floor level. An integral hoist on a monorail can be furnished if desired. Material can discharge by gravity into storage, a process vessel or a conveying system for transfer to another location. Modular construction of the discharge portion underneath the bed facilitates the use of a wide range of devices such as feed screws, rotary valves, lump breakers. http://www.khodiyarinfratech.com/jumbo-bag-unloading-system.html
