   Tanker and Truck Loading Bellow

 


Tanker and open truck loading bellows are also known as loading chute and loading spout. Open truck and tanker loading bellows are used for rapid and efficient dust free loading of dry bulk solids to tankers and open trucks. Free flowing bulk solids in powder and granule form are easily transferred from silos, hoppers, containers, screw feeder to tankers, open trucks, ships or stockpiles

Tanker Loading Bellow


Tanker loading bellows are used to fill the tanker trucks without any dust emmission. The lower discharge cone of the bellow is placed on inlet flange of the tanker. The product in powder or granule form is automatically discharged into the tank. When the tank is full the sensor of the bellow generates a signal to stop the product flow. An optional dust collector vacuums any remaining dust.

How Tanker Loading Bellow Works?

Bulk solid in powder or granular form is transferred from silo, hopper or conveyor to loading bellow. It directly falls down through the inner side of the bellow. The tank is filled by the product. Air content of the tanker is transferred through the outer piping of the bellow. It is then discharged through the air vent. An optional filter system is used to filter the air. A limit sensor is used to stop the loading operation when the tank is full.

The loading bellow is retracted before the tanker is placed below the silo. Feeding devices or valves are in closed position during this period.

After the tanker is placed below the silo, the bellow is moved downside. When it reaches to the tanker inlet, it stops. After that product flow is started. The sensor of the bellow waits for the filling and stops the operation when the tank is full. The bellow is retracted again and stops.

Depending on the flowing properties, bulk materials cannot be completely filled into the tank. For materials which have low bulk density (like animal feed, wheat etc), the tanker cannot be filled up to its maximum carrying capacity.

A spreading system is developed to solve this problem. The spreader is positioned near the outlet spout in loaders for loading to tanks. It is particularly suitable for use with powdery, light materials since, owing to the rotation of a fan, the material is distributed uniformly inside the tanker allowing entry of a larger quantity of material. Since the filling efficiency of the tanker is increased, the overall transportation cost will decrease.

Open Truck Loading Bellow


Open truck loading bellows are used to fill the flatbed open trucks without any dust emmission.The loading bellow outlet is placed on the truck base. The free falling product is transferred to the truck. The flexible dust skirt prevents the dust coming outside of the loading region. When the level of product in the truck increases the system automatically rises. An optional fan and dust collection system collects any dust in the region and prevents dust emmission.

How Open Truck Loading Bellow Works?


At the beginning of open truck loading, bellow is lowered towards the flatbed of truck and stops at the bottom. Flexible dust skirt located at the bottom side of bellow keeps the dust content inside the loading region. During material discharge, it provides a closed containment for dust. Dust collector 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 bellow dust skirt. When the material level increases, bellow 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 bellow is closed. System waits for few seconds to complete product flow and to collect remaining dust by dust collector. Loading bellow automatically retracts to the top position afterwards.

Ship Loading Bellow


Ship loading bellows are used to fill the bulk solid carrier ships without any dust emmission.The loading bellow outlet is placed on the ship base. The free falling product is transferred to the ship. The flexible dust skirt prevents the dust coming outside of the loading region. When the level of product in the ship  increases the system automatically rises. An optional fan and dust collection system collects any dust in the region and prevents dust emmission.

Stockpile Loading Bellows


Stockpile loading bellows are used to fill the stockpiles without any dust emmission.The loading bellow outlet is placed on the basement of the stockyard. The free falling product is transferred to the stock region. The flexible dust skirt prevents the dust coming outside of the loading region. When the level of product in the stockpile  increases the system automatically rises. An optional fan and dust collection system collects any dust in the region and prevents dust emmission during stockpiling.
