Telescopic loading chutes are coupled with product feeding equipment. Depending on application requirements, wide range of bulk solids handling equipment can be utilized for feeding loading chutes.
Butterfly valves are generally installed below silos or hoppers. Product discharge outlet can be completely opened or closed in short time with the help of butterfly valves installed above telescopic loading chutes. In truck filling applications, butterfly valves serve to control amount of product loaded.
Slidegate valves are generally located at the silo and hopper outlets. Pneumatic piston controlled slidegate valves are used to start and stop product loading in short time. Screw and gearbox controlled slidegate valves can be used to adjust bulk material loading speed by adjusting gate opening size.
Screw conveyors are used for transferring bulk solids from hoppers, silos or plant machinery to loading chutes with controlled speed and capacity. Depending on loading area conditions, screw conveyors can be used to move the bulk solids to higher levels before entering into loading chutes to save some height for trucks.
Belt conveyors can be utilized to transfer bulk materials to telescopic loading chutes. They are generally preferred in open regions and stockpile loadings. Special designed intermediate hoppers are used for smooth discharge of bulk materials from conveyor belt outlet to loading chute. Depending on dust load of the conveyed material, extra dust collectors can be utilized.
Rotary valves are used for discharging bulk materials from silos and hoppers with controlled speed into the telescopic loading chute systems.
Pneumatic Conveying System
Pneumatic conveying systems are preferred in plants where loading area is far from the bulk material storage equipment. Pneumatic conveying systems transfer bulk materials from storage units to telescopic loading chutes within pipelines with air pressure or vacuum. Pneumatic conveying capacity is determined and equipment is selected with respect to transfer distance and loading chute capacity.
Airslide conveyors are utilized in high capacity loading of fine powdered materials such as cement loading to tanker trucks in cement plants. Telescopic loading chutes installed are below the outlet of air slide conveyors. Bulk material is fluidized within airslide conveyors with the help of pressurized air coming from the bottom. By the help of gravity, they move towards the downside direction. The inclination of airslide conveyor directly effects the flow speed.
Extensive range of telescopic chutes are available for wide range of applications. Open truck loading, bulk tanker filling, stockpile loading and bulk ship loading chutes provide dust free outloading of bulk materials for industrial applications.
Bulk solid transfer equipment are used to transfer powdered and granular materials to telescopic chutes. Bulk materials are discharged from silos, hoppers, production lines with these transfer and conveying equipment.
Telescopic loading chutes and bulk solid discharge systems can be provided with extensive range of optional components and accessories for different application needs. Proper selection of accessories is essential for efficient and dust-free loading.
