Bulk bag discharger solves dust problem
Manufacturer of high quality bathroom products Thomas Dudley has created a safer working environment and inmproved performance since taking delivery of a bulk bag discharger and flexible screw conveyor from specialists in handling of bulk dry materials Spiroflow

ounded in 1920, Thomas Dudley manufactures high quality bath- room products, plastic toilet cis- terns, and ferrous castings said to be innovative and reliable. Today, this commitment is as strong as ever, result- ing in the continued introduction of new toilet cisterns, and ferrous castings that challenge conventional thinking.
It was these commitments which, in 2012, led Thomas Dudley to develop ‘Resan’, a range of resin cast vandal- resistant sanitary-ware products for use in high security units and public areas. In the early stages of the ‘Resan’ product development, additives were delivered in bulk bags yet were hand- weighed and mixed to the correct con-
Crane systems boost efficiency T
erex Material Handling has supplied two Demag overhead travelling cranes for CMS Cepcor’s
Technical Centre, located near its head office in Coalville, Leicestershire. CMS Cepcor is an aftermarket supplier of premium crusher components to the mining, quarrying, aggregate, demolition and recycling industries. The company exports to more than 100 countries and has recently received the Queen’s Award for Enterprise: International Trade 2012.
The company’s £3 million investment in the development of the 30,000ft2 Technical Centre includes state-of-the-art CNC machine tools and infrastructure, which provide additional resources for increased production capacity, facilitating further growth of export business. A wide range of spare
part components, in various grades of carbon steel, is manufactured at the plant. To meet CMS Cepcor’s specific material handling requirements, Terex Material Handling supplied two Demag 24.5m span, 12.5t SWL single girder overhead travelling cranes, each with a Demag DR-Pro 10 electric wire rope hoist. The crane systems have two long travel speeds of 20 and 5m/min, variable cross travel speeds of 5 to 30m/min and hoisting speeds of 4.0/0.7m/min. Operation is via a Demag DRC-10 radio remote control, for smooth movement and accurate positioning of components within the CNC machining centres. CMS Cepcor’s technical director, Chris Sydenham, reported that the crane systems had
improved manufacturing efficiency considerably. “Many of the components we produce are one offs and set up represents a large proportion of the manufacturing cycle. Accurate movement and positioning of heavy and often awkward shaped components, within the machining centres, has helped us reduce set up times for improved productivity.”
Demag engineers worked closely with installation contractor, Lifting Systems, in addressing technical aspects of the project, created by the constraints of the existing building structure. Low headroom and a requirement for a minimum of five metre height to the underside of the crane girder, to ensure clearance above machines, were included amongst the engineering and installation issues. Chris Sydenham adds: “We have been very impressed by the high standards of customer service and attention to detail, which we have received throughout the process.” Demag Cranes & Components

Materials Handling & Logistics MARCH/ APRIL 2013
Thomas Dudley has taken delivery of a bulk bag discharger and flexible screw conveyor from Spiroflow
sistency before being poured into cast- ings. This process was time consum- ing and created high levels of dust, hence, the need for an effective bulk bag discharge system.
After evaluating various bulk bag dis- charger manufacturers, Spiroflow was identified as the preferred supplier; it was able to meet the required delivery, guarantee performance and supply loan equipment during the manufacture process. Tests witnessed by Mike Mohr, works director and Neil Ward, produc- tion engineer, at Spiroflow’s Test Centre confirmed that a ‘Spiroflow’ T5 Bulk Bag Discharger and 67 Flexible Screw Conveyor was the correct combination to unload the bulk bags and deliver the additives to the inlet at the top of a con- tinuous casting machine where bulk material is mixed with solid fillers and liquid binders.
The ‘Spiroflow’ T5 bulk bag dis- charger is designed for installations where restricted headroom causes problems in lifting bulk bags in to position on the discharger or where only a low lift forklift truck is avail- able. The discharger can be coupled directly to a flexible spiral or other suitable conveyor to meter product from the bulk bag either volumetri- cally or by weight.
Materials may then be fed direct to either mixing or other process equip- ment to provide a fully automatic powder unloading, proportioning and transfer system.
Mohr confirms: “Our biggest worry was dust control and air contamina- tion. The Spiroflow Bulk Bag Discharger has surpassed our expecta- tions, created a safer working environ- ment and increased our flow of production.

“Once Spiroflow had commissioned the conveyor its service engineer spent a day training our operatives on the correct usage and preventative mainte- nance procedures to ensure we con- tinue to receive optimum performance from our equipment,” says Mohr.
