Combined telescopic loading spouts are used for dust free loading of powdered and granular bulk solids both into tanker trucks and flatbed open trucks. Free flowing dry bulk solids in powder and granule form are easily transferred from silos, hoppers, containers, screw feeder to trucks. There exists flexible dust skirt and poliurethane coated discharge cone together at the same loading spout unit. Combined loading spouts are suitable for applications where incoming truck types vary.
Operation of Combined Truck Loading Spouts
Combined truck loading spouts have two operation modes selected from control panel at the beginning of truck loading. Depending on type of truck (open truck or tanker truck) loading spout operation scheme changes.
Open Truck Loading Mode
At the beginning of open truck loading, spout is lowered towards the flatbed of truck and stops at the bottom. Flexible dust skirt located at the bottom side of spout keeps the dust content inside the loading region. During material discharge, it provides a closed containment for dust. Dust collection system collects any fugitive dust in the region and prevents dust emission to surrounding. Collected dust is sent back to the product stream continuously and no material is wasted during loading. Built in level sensors monitor the product level below the loading spout dust skirt. When the material level increases, spout is retracted upwards automatically and it maintains a space to let the material flow rapidly. After truck loading is finished, product discharge valve above the loading spout is closed. System waits for few seconds to complete product flow and to collect remaining dust by dust collector. Loading spout automatically retracts to the top position afterwards.
Tanker Truck Loading Mode
At the beginning of tanker loading, spout is lowered and stopped when it reaches to the tanker inlet automatically. Poliurethane coated discharge cone fits vessel inlet to prevent any dust emission during tanker loading. Material falls freely through the inner side of the spout. After bulk tanker filling is started, built in vacuum fan evacuates the air trapped in the vessel to increase product flow rate. This vacuumed air passes through the dust collector. Dust content in the air is trapped by filter units and sent back to the tanker with the help of automatically operated pulse jet valves. Level sensor placed at the bottom monitors the product level in the tanker truck. Level sensor sends a signal to stop loading, when the tanker is full. Product discharge valve above the loading spout is closed. System waits for few seconds to complete product flow and to collect remaining dust by dust collector. Loading spout retracts to the top position automatically.

Cement, fly ash, mining minerals, calcium carbonate, pvc, plastic pellets, plastic powders, alumina, bentonite, bauxite, coal, cement clinker, gypsium, kaolin, limestone, marble powder, soda ash, quartz, urea, sodium sulphate, wheat, flour, animal feed, seed, corn, rice, sugar, salt and similar powdered and granular dry bulk solids.
Extensive range of loading spouts are available for wide range of applications. Open truck loading, bulk tanker filling, stockpile loading and bulk ship loading spouts provide dust free outloading of bulk materials for industrial applications.
Bulk solid transfer equipment are used to transfer powdered and granular materials to loading spouts. Bulk materials are discharged from silos, hoppers, production lines with these transfer and conveying equipment.
Loading spouts 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.
