Tough lining protects quarry equipment
Abrasion resistant chromium carbide wearplate fitted in a giant vibratory feeder under a stockpile feeder at Lafarge Aggregates' Mountsorrel quarry.
Ace Arc has supplied a tough lining to protect quarry equipment as it is battered by 2500tonne of granite an hour The abrasion resistant chromium carbide wearplate - Ace 600 - is fitted in a giant vibratory feeder under a stockpile feeder at Lafarge Aggregates' Mountsorrel quarry
The Mogensen machine powered by twin Invicta vibrators and manufactured at its Grantham facility is the third to be installed on the site but has 60% more capacity than the other two.
Another machine fitted with the wearplate has been sold to European Metal Recycling where it is installed under a fragmenting shredder managing hundreds of tonnes of scrap metal an hour.
Mogensen showed a machine fitted with Ace Arc wearplate at Hillhead 2005, Europe's biggest quarry show.
Kevin Bennett, Applications Engineer at Mogensen, said: "The Ace 600 material is very high quality".
"It's a premium product but it means you spend less time replacing and maintaining it".
"Because it's supplied in a modular form, you can replace sections from hard wearing areas and extend the life of the wearplate by swapping modules from hardwearing areas to lighter wearing areas".
Mogensen has found that the chrome polishes during use encourage the smooth passage of material through the equipment.
Ace Arc recently increased its capacity to produce wearplate by 50% in response to demand by the quarrying, mining and construction industry for short turnaround times and competitive pricing.
An investment of over £40,000 in technology doubled the existing production capacity of one of the firm's two wearplate manufacturing machines.
Ace Arc Managing Director Frank Fairbrother said: "This investment and the resulting increase in capacity allows us to work to even shorter deadlines and produce one-off and standard orders more quickly and competitively - vital for our continuing success in export markets".
Manufactured to customer specifications, Ace 600 wearplate meets the arduous operating conditions encountered in quarrying, mining, construction and other engineering applications where equipment is subject to excessive abrasion and wear.
It comprises a chromium carbide overlay material fused to a mild steel backing plate.
During the computer-controlled manufacturing, a homogenous layer is formed between the welded surface and the backing plate, creating a strong metallurgical bond.
The result is an extremely abrasion resistant wearplate with a typical hardness of 58 to 62RC.
The upgraded machine has four welding heads instead of two and a computer system enabling it to memorise welding parameters for individual plate specifications.
To ensure optimum high-wear resistance, chrome levels combined with the size and distribution of the carbide content are carefully formulated to achieve material compositions providing maximum wear life.
Various grades of chromium carbide plate are manufactured to meet demanding applications covering heavy abrasion, high temperatures, chemical attack or corrosion.
Production is carried out within closely monitored parameters - more than 25 separate checks are made on hardness and thickness during manufacture to guarantee consistent product quality and ensure that ISO 9001:2000 quality standards are met.
The wearplate can be supplied in a range of sizes and thickness, with optional thickness ratios of hard facing to backing plate also available on thicknesses over 10mm.
Fixing is achieved by conventional welding, countersunk bolts or with stud fixings onto the mild steel backing plate.
A design and cladding service is also available where wearplates have specific needs, for instance a double layer on a feed or impact point.
This is a fully customised service using CNC manufacturing equipment.
Repair and rebuild work for primary and secondary crusher parts can be carried out, as either an on-site or workshop operation.
