Jet Slingers

HMA Techniplan slingers are a tried and proven solution for stockpiling and ship loading applications. Techniplan slingers have been used successfully on the following bulk material:

  • Coal - washed and raw (Capacity up to 3000 tph)
  • Woodchips – hardwood and soft wood (Capacity up to 1500 tph)
  • Grains – Wheat, barley, Maize (Capacity up to 1000 tph)
  • Sugar (Capacity up to 3000 tph)
  • Mineral sands – ilmenite etc (Capacity up to 1000 tph)


Techniplan has developed a number of innovative concepts which set its slingers apart from others.

Quick Belt Change Facility

The quick belt change facility does away with the need to dismantle the slinger in order to change a conveyor belt. It also does away with the need for cranes and heavy lifting equipment. More importantly, the change can be effected in under an hour by an experienced crew. This means that an unscheduled belt change does not necessarily mean long interruptions and delays to ship loading or stockpiling operations.

Integral Bypass Chute

The integral bypass chute allows material to be directed to the belt or past the belt. The chute is not an obstructive flap valve. It is an open free flowing tilting chute without ledges or impediments to the passage of material.

Correct Geometry

Techniplan slingers load tangentially onto the belt, maintaining correct loading geometry under a wide range of trajectory luff angles. This is achieved without changes in the relationships between pulleys and consequently without changes of belt tension.
