Ibstock Brick are the UK’s leading manufacturers of clay products and
employ nearly 1400 people in the UK spread over 19 sites.
The sites are located throughout the UK and most have associated
quarrying operations at or near to them.
In order to meet the increasing demand for the supply of bricks, Ibstock
Brick have extended their manufacturing capability at the new Ibstock site
in Coalville, Leicestershire.
The new factory can produce 100 million bricks per annum, coupled with
the existing manufacturing on site; it will mean 190 million bricks per
annum total output from the Ibstock site, or an amount equivalent to
around 28,000 new homes per year.
Silica is a natural substance found in materials common on construction
sites, like concrete, rocks and sand. The dust created by cutting,
grinding or drilling concrete products can contain respirable crystalline
silica. Over time, exposure to these silica particles causes scarring in
The control of airborne silica dust is a constant challenge for
industries that create the dust. The key to preventing silica exposure is
to keep silica dust out of the air. That’s a tall order for giant
manufacturing sites like Ibstock Brick.Former methods like broom sweeping
are neither efficient nor effective, which is why Ibstock Brick contacted
Tennant to help find a solution.
Tennant offers three types of dust control methods that can be used to
support silica control housekeeping requirements. As Tennant developed
it’s offering, they worked closely with Ibstock Brick to test their HEPA
enabled S20 sweeper.
The Tennant S20 is a versatile and durable mid-sized industrial sweeper
with a three-stage primary filter system, plus the option was made
available for a 4th stage HEPA dust filter.
"A HEPA filter has a special filter media that can clean to a very high
standard by removing microscopic particulate from the air" - Jamie Harris
Tennant National Account Manager.
Based on Ibstock Bricks testing, the HEPA filter should last at least six
months, possibly up to a year depending on the customer’s application.
Proper usage and maintenance practices will help increase the
effectiveness of the machine’s filtration stages and the life of the HEPA
Stage 1 – Perma-Filter™ Tennant engineered design helps
keep bulky debris, moisture and dirt in the hopper removing 90% of
particulates from the air stream.
Stage 2 – SweepMax® Plus Cyclonics Longer filter life
with exclusive cyclonics dust control that removes an additional 90% of
dust particles from the air stream before reaching the filter.
Stage 3 – Canister Nanofiber Filter MERV 15-rated, flame
retardant Donaldson Ultra-Web® filter loads and shakes-back 70%more
effectively, and provides cleaner air from filtering sub-micron dust
particulates down to .5 microns at 99% efficiency.
Stage 4 – HEPA Dust Filter Dry system providing a
filtration efficiency of 99.97% to .3 microns.
Ibstock Brick’s new Eclipse site was awarded the Industry Pledge Award
for measures to control dust within a factory.
Mike Wardle – Hygiene and Cleaning Supervisor Ibstock Eclipse:
Without the Tennant Machines we would not be able to keep the site clean
and safe, the S20 and T20 in particular helps us maintain a clean site and
are easy to use and do a great job helping us keep the dust levels low on
site and help us keep the floors clean and safe"
Michael Caughey - Senior Production Manager Ibstock Eclipse:
"Tennant have provide us support and helped us identify machines that have
helped us in keeping the new factory clean. The Tennant equipment helped
us gain the Industry Pledge Award for measures to control dust within a
factory in December 2018 which is something that we are very proud of and
would have not achieved this without the Tennant machines that we have on
