tarting with news from the coal handling sector and
Siwertell, part of Cargotec, has received an order from
Hyundai Engineering Co. Ltd for a rail-travelling Siwertell
ST 790-D unloader for installation at the Therma Visayas
power plant in Toledo, Cebu, Philippines. The fully enclosed, screw-type
unloader will be used to discharge coal from vessels of up to
92 500 DWT at a rated capacity of 1500 tph.
This is Siwertell's third recent contract for Philippine coal-fired power
plants, according to Ola Jeppsson, Sales Manager at Siwertell. “It follows
unloader contracts for the Pagbilao and Therma South power plants,”
said Jeppsson. “In all cases the customers needed a high-efficiency,
environmentally-friendly unloader. They chose Siwertell because we are
the world's leading supplier of unloaders meeting these important
requirements.”
The unloader will be constructed at Siwertell's sub-contractor's
premises in Nantong, China. Delivery of the fully-constructed machine
by heavy lift vessel is anticipated for mid-December 2016. Final
commissioning and performance tests will then be carried out at the
power plant.
Return idler cage
One of the most easily preventable conveyor accident sources is a
dislodged return idler falling onto an unsuspecting worker. Misaligned
belts often come into contact with return idler brackets, shearing them
off and allowing the idler to break free. To solve this safety hazard,
ASGCO
®
has developed the ASGCO Safe-Guard
®
return idler cage.
According to the company, the Safe-Guard
®
return idler cage is
designed to catch the return idler from falling onto workers or
equipment, preventing injuries and damage to critical components. The
cage is made of durable powder coated A36 steel and requires no
welding, while the open design allows for fugitive material to pass
through, preventing additional complications from build up.
The Safe-Guard
®
return idler cage is easy to install and remove for
belt maintenance using the quick mounting kit, which includes beam
clamps, links and adjustable chains, concluded the company. It is
available in various sizes to fit most belt conveyors and is OSHA/MSHA
approved.
New FMS medium-duty secondary cleaner
Staying with conveyors and Flexco has introduced the FMS
medium-duty secondary cleaner to its line of belt cleaning products.
Made with heavy-duty steel with a corrosion-resistant powder coating,
the FMS is ideal for use on mining conveyors with belt speeds up to
1000 ft/min. (5 m/sec.), the company said in a press release. It can be
used for belt widths ranging from 18 in. to 72 in. (450 mm to 1800 mm),
with additional sizes available upon request.
The thin hard edges of the 6 in. (150 mm) wide metal blades deliver
high cleaning efficiency and long wear life, while the spring tensioner
ensures that there is consistent blade-to-belt interaction and constant
pressure on the belt. Impact-resistant C-Tip tungsten carbide blades are
available for use with Flexco mechanical splices.
“The spring cushion allows the C-tips to move away from a passing
splice without damage and with minimal cleaning disruption,” said
Ryan Grevenstuk, Senior Product Manager for Flexco. “V-tips, for use
with vulcanised belts, are also available on the FMS.”
When combined with the MSP standard mine-duty precleaner and/or
the MMP medium mine-duty pecleaner, the system provides optimal
