CEMENT DISAB case study: H & T Services “Although we do a huge amount of ‘vacuumation’, as we like to call it, of spillages within cement plants with our DISABs, what we also do - as opposed to other contractors - is that we then use the blowing facility on our DISAB units to blow material back into the process etc. This facility reduces the need for tipping on-site and prevents any dust escaping into the atmosphere- allowing the materials to be re-used.” Based near Rugby, a major part of the business undertaken by H&T Labour and Vacuumation Services is with some of the biggest names in the cement industry, and H&T plays a significant role when it comes to these companies setting, improving and achieving very high standards of environmental performance. The H&T DISAB Vacloader fleet H&T operates five DISAB Centurion LN200 8-1812 machines, along with a DISAB-Tella SDW 3.5 tonne ‘Big-Bag’ machine, identical to the BagVACs deployed by the UK subsidiary of the DISAB Group, Gotland Ltd. According to Dave Blundell, Operations Manager at H&T: “The DISABs are unique – they provide higher levels of performance and a greater range of capabilities compared to any other similar truck-mounted machine. There’s nothing quite like a DISAB.” “We are also big users of the DISA FLOW couplings system. These are light-weight and easy to handle by one man. We like the idea of the smooth inner surface which assists with the speed of material movement and reduces the possibility of build-up. Another advantage of this coupling system is that we only have to purchase male couplings which are joined flange-to-flange

Unique capabilities “To give you an idea of what that means, we recently carried out a job major cement plant in Rugby that involved their large storage silo that’s used to hold clinker, the material that’s then ground with gypsum to form cement. This silo is 50 metres in diameter and around 45 metres high to the top of the side wall, and that’s where we had to get the suction hose from the DISAB on the ground.” “The problem was that the rubber seal around the top of the silo wall where the roof sat was filled with dust. The seal itself was failing and allowing dust to escape into the atmosphere,...
