What Are Telescopic Loading Spouts Used For?

Telescopic loading spouts are typically utilised for gravity dust free feeding of a wide range of diverse products from storage silos to static or movable tanks. The loading spout will have a fixed filling head that is attached to a discharge valve of a silo. There is a retractable head used for the filling that is fitted to this, which when needed will be lowered onto a road tanker for filling and once the job has been completed, can retract either automatically or manually.

Specific Uses:

  • Loading spouts have been designed to load dry, dusty products into closed railway cars and trucks.
  • Loading dusty bulk solids into trucks when efficiency is paramount and the need for minimum wastage is a critical issue.
  • Loading spouts that have been created for efficient dust-free loading of dusty and dry bulk solids onto large stockpiles.
  • The ship-loader is a telescopic loading spout that enables high-capacity ship loading.
  • The loading sprout can load large amounts of cargo into holds of river and seagoing ships. The machinery is designed so that the weight is evenly distributed in the hold in a relatively short space of time.
  • Combined loading sprouts have been designed for use in open vehicles, tankers, and rail cars.

Different Types of Telescopic Loading Spounts for Various Purposes

A loading spout that is manually operated has a lightweight filling head that is lowered manually into the manhole of a tanker. There is a sleeve that gives vertical and horizontal travel, which enables easy positioning onto a truck’s filling hatch. Because it is manually operated, this device will not have any level detection monitor. This is, therefore, best suited to a silo, which is placed on ‘load cells’, or if the tanker is being weighed on a weighbridge.

With an automated system, the loading sprout can be manoeuvred by the operator and comes with an electric brake geared motor and sensors that automatically stop the flow of material. The loading head is protected by a sleeve to make sure that the sensor is not damaged when it is being lowered, and the switch level ensures that the process cuts out when the tanker has reached its maximum capacity.

Loading heads are made of rubber. This makes sure that there is a seal that is tight, to stop dust escaping during the loading process. For abrasive or hot materials, the sprout can still be used with a metal head.

Why Use Loading Spouts?

  • The advantage of a loading sprout is particularly noticed when it is employed in a dust free area, as there is no dust leakage to pollute the air.
  • The loading sprout is highly adaptable for use in all types of bulk solid transfers and stock systems.
  • It is possible to use different equipment such as conveyors, screw feeders, hoppers, and silos.
  • There is a broad range of different models on the market for diverse operations. There are also loading sprout systems that can be used for several types of loading operations.
  • One of the advantages of using telescopic sprouts is that wastage is kept to a minimum, which in the harsh economic climate of today can make a big difference between profit and loss accounts.
  • Loading sprouts are very versatile, and the conical discharges will fit into all tanker inlets
  • The sprout loading system can be used for materials that have temperatures of up to 250-degree centigrade.
  • There are numerous food grade sprout systems available that offer a sterile solution to storage and transport.

The loading sprout is particularly suited to materials in powder and granule form such as:

  • Cement
  • Calcium carbonate
  • Mining materials
  • Fly ash
  • Coal dust
  • Gypsum
  • Perlite
  • Ceramic powders
  • Plastics and polyethylene
  • Foodstuffs – flour, wheat, salt, corn, sugar and seeds

A lot of the time these types of loading sprout systems will be operated in conjunction with diverter valves, spin-loaders and slide gates, to control the flow of material during loading. You will see them in constant use in grain elevators, cement plants, ship and river ports though in the industrial sector their applications are boundless and very versatile. From an environmental perspective, airborne fugitive dusting is a major concern and can result in a substantial penalty or a company being shut down. Having a telescopic loading spout system in operation for loading gives peace of mind for enterprises because they are assured of good air quality during the loading process and after.
