A new way of securing vibrating screen and crusher motor bolts has been shown in service to save two-thirds of the time previously taken for the installation and maintenance of the drives of this comminution equipment, according to Australia-based Technofast.

Technofast EziTite® Hydraulic Nuts are used to secure vibrating mechanisms and drive motors to sieves, screens and comminution equipment so as to avoid downtime and maintenance. They are actuated simultaneously to give accurate, even and simultaneous torquing across sets of bolts used in crusher screen applications such as mineral processing and the sorting of industrial materials.

The EziTite fasteners for vibrating and crusher applications incorporate a poly washer for extended service, eliminating problems such as hex nuts vibrating loose, lack of control of the bolt load, and physically demanding and hazardous use of flogging spanners, the company says.

Technofast Founder and CEO, John Bucknell, said: “One of the issues facing operators of this type of equipment is the propensity for bolts to loosen under the constant vibration and cyclic loading. We have alleviated this issue by incorporating a flexible poly washer to augment the outstanding performance of the EziTite fasteners in service.

“One typical quarry and mining application in Western Australia dramatically cut the installation time of the motor bolts from a six-hour operation needing two or three personnel, to a two-hour operation involving two people. The machine operator involved reported that using the poly washer as a shock-resistant component and tensioning them simultaneously with precise accuracy is a game changer.”

He added: “Not only did the application benefit from easy installation and safer handling, but also the simultaneous and precise tensioning of the EziTite nuts produced highly accurate bolt loadings without the ‘cross talk’ coming from individual torque tightening. This resulted in a safer, more secure and longer-lasting joint.”

Technofast has more than doubled the size of its Brisbane, Australia, premises in recent years as a result of expanded global demand for its products, which are typically used where rapid, simplified, and safe maintenance is important and secure and long-lasting joints are integral to safety. Applications range from the servicing of nuclear reactors and conventional turbines, through to partnerships with the likes of Framatome and Siemens in areas such as mineral processing, motors, crushers, dragline drums, cranes, mantle nuts and gearbox coupler.

Checkproof app to help digitise FLSmidth’s maintenance, service workflow

Software as a service company, Checkproof, says it has expanded its agreement with FLSmidth as the mining OEM looks to streamline its maintenance and service work across the globe.

The move follows Checkproof’s work on digitising FLSmidth’s front line work on sites in China, India, Kazakhstan and Arizona (USA), it said.

To support FLSmidth’s work on maintenance and service inspections of its product lines, the CheckProof app is used to perform and report front line daily tasks in any mobile device, securing routines, traceability and follow-up work, the company says.

Checkproof has also been implemented to digitise processes and to support company improvements for quality control of final assembly inspections at FLSmidth’s manufacturing facilities, it said.

Having first implemented the app in China, in 2017, FLSmidth has now gone global with CheckProof.

Tony Durant, Head of Mining Service Execution Europe, Russia and North Africa, FLSmidth, says: “CheckProof has given us the opportunity to change the way we work; to build a coherent and standard methodology to digitise our maintenance services deliverables at one of our customer’s sites. It offers an easy way for us to monitor the status of equipment and all daily maintenance activities.

“The tool itself is easy to use and can be quickly adopted for different kinds of equipment maintenance scenarios. This, combined with the ability to construct libraries within CheckProof, allows working procedures with only minor adaption needs to be scaled quickly, so minimising repeated work creation effort.”

Håkan Holmgren, CEO and Founder of CheckProof said the latest global agreement with FLSmidth represented both a natural and exciting step for the company.

“It’s an acknowledgment that CheckProof generates results, and we are particularly glad to have the confidence of a world-leading player such as FLSmidth,” he said. “We will continue to work hard to support their day-to-day operations and to improve performance, for FLSmidth to reach their goals and offer sustainable productivity worldwide.”
