DYMOT DEVELOPS AUTOMATIC CONVEYOR BELT TENSIONING SYSTEM WITH VFD

Product News Monday, March 6, 2017: Dymot Engineering Co. (Pty) Ltd.

GENERAL INFORMATION

The modern high speed, large capacity, long length conveyors have created a need for an alternative to gravity TAKE UP SYSTEMS for TENSIONING these high production machines.

DYMOT ENGINEERING has developed an electronic tension control system specifically for this purpose.

A VFD is incorporated into the system which offers multiple advantages as listed below.

ADVANTAGES

• Controlled Starting via VFD.
• Mechanical Life of Winch and related equipment prolonged.
• Less Power Consumption as Torque is limited in the Drive.
• Almost No Brake Wear as the Motor will be held under full Torque at 0Hz when Brake is applied for Parking.
• Faster Response due to the Winch Active in Startup – Pre Tension Phase.
• Tension controlled more precisely - Drive speed automatically adjusts in relation to Torque Level.

SYSTEM INCLUSIONS

• I.P. 65 Enclosure.
• Lockable Isolator.
• V.F.D.
• Motor Protection Unit for above.
• Control Transformer + Protection
• Brake Contactor + Protection.
• Cooling Fan Contactor + Protection.
• Power Supply + Protection.
• PLC Fully Programmed.
• H.M.I. Panel Mounted Touch Screen for operator information and control.
• Emergency Stop Button.
• Remote P.L.C. Interposing Relays.
• 25% Resistor Bank.

All the above will lead to less maintenance time and cost for both the conveyor and the tensioning equipment thus increasing the availability of the belt.

Dymot is involved with the majority of Mining Projects and have products in more than 40 countries.
