Martin Engineering reveals new secondary belt cleaner

September 24, 2014, Neponset, Ill. – Martin Engineering has
announced a secondary conveyor belt cleaner engineered to improve performance
and reduce maintenance time, even as average belt speeds and loads continue to
increase. The Martin SQC2S Cleaner features individually cushioned tungsten
carbide blades for effective cleaning without risk to the belt or splices. 

September 24, 2014, Neponset, Ill. – Martin Engineering has
announced a secondary conveyor belt cleaner engineered to improve performance
and reduce maintenance time, even as average belt speeds and loads continue to
increase. The Martin SQC2S Cleaner features individually cushioned tungsten
carbide blades for effective cleaning without risk to the belt or splices. 

The new design forms a single sealing edge that maintains
steady, adjustable pressure. Patented rubber buffers maintain the cleaning
pressure throughout the blade’s life, while deflecting sufficiently to allow
splices to pass without harm and ensuring compatibility with reversing belts or
those that experience backup at shutdown. Moving parts are zinc plated to
resist seizing or rusting.

“The blades conform to the belt profile, adjusting individually
to deliver continuous contact across the belt,” explained Dave Mueller, Senior
Product Specialist at Martin Engineering. “In a perfect world, bulk materials
would load uniformly, wearing the blade evenly, but that rarely happens. By
having multiple segments attached to a single rigid assembly, the tension can
be maintained and adjusted accurately, quickly and safely.”

The rugged construction is engineered to withstand punishing
conditions, such as high belt speeds, high-impact transfers and high tonnage
loads. Designed for a maximum belt speed of 1000 fpm (5.08 m/sec), the cleaner
is suited for belt widths from 18 to 96 inches (~400 to 2400 mm). 

To match the requirements of specific applications, the unit
features straight 5.91 inch (151 mm) individual blade sections or 3 inch (76.2
mm) individual blade sections, attached to a sturdy square mainframe. Replaceable
urethane blades are color-coded according to their continuous temperature
rating, ranging between -40° to 350°F (-40° to 177°C). Tungsten carbide tips
can be specified for normal, acidic or high-impact conditions. The rubber wear
strip is supplied in continuous lengths up to 100 feet (30.48 m).

Blade removal and replacement is a simple operation on the
SQC2S by removing the lock pin from the main assembly and sliding out the
cartridge. The lock pins are a key component to Martin Engineering’s “no-reach
design,” which allows workers to conduct their lockout / tag-out procedure more
safely. This innovation is one reason why the unit is a member of Martin
Engineering’s Safety First family of products, helping customers achieve OSHA
compliance.

“We work with all types of bulk material, from biomass to
aggregate to sticky sand, each with different requirements,” said Mueller. “So
our products are developed to improve efficiency and safety, without
compromising belt health. This design gives customers more options, regardless
of the nature of the bulk material being conveyed.”
