Patents pending on two of CDE’s many improvements to its Evowash plant

Materials washing specialist CDE is displaying three updated machines at bauma 2013 – the Evowash, the M2500 and the Agg Max 83R. All three machines have benefitted from CDE’s in-house ‘Worldbeater’ programme, which sees teams of staff pitted against each other to come up with new ideas.

CDE’s latest Evowash plant boasts two patented items among its many changes.
Materials washing specialist 3168 CDE Global is displaying three updated machines at bauma 2013 – the Evowash, the M2500 and the Agg Max 83R.

All three machines have benefitted from CDE’s in-house ‘Worldbeater’ programme, which sees teams of staff pitted against each other to come up with new ideas.

Although all the machines boast improvements compared to previous versions, Evowash has benefited from the most changes, including two ideas with patents pending.

“We have been evolving the Evowash ever since we invented it 20 years ago, hence it’s name,” said Iain Walker, technical sales manager for the Middle East. “But this is the first time we have made such a large number of changes at once.”

CDE has made radical changes to the dewatering screen. First, the whole structure is bolted rather than welded, since welds are a potential weak spot when the screen is vibrating.

Second, rather than mounting the motors on a bridge structure which spans either side of the screen to brace the metal sides, the motors are an integral part of the structure. This reduces the weight of the screen by 30% and means that it requires 30% less power.

Finally, the feed box is on rails, which means it can be moved forward to provide more space for maintenance.

Improvements on other areas of the plant include mounting the pump on a turntable so that it can be swivelled round to allow easy access for maintenance. A built-in boom arm means that no additional lifting gear, and only one person, is required to work on the pump. The boom can be dismantled, unbolted and re-erected next to the screen to aid maintenance of the motors.

The M2500, first launched by CDE in 2010, combines a loading hopper, inclined feed conveyor, two-desk washing screen and integrated Evowash. “It was the first of its type,” said Walker.

The latest version incorporates a number of modifications, most of them aimed to make maintenance easier, safer and faster. Some of the improvements made on the newest Evowash have already fed through into the M2500.

The AggMax 83R is a scrubbing machine, which has found most of its customers in the UK, but is now being bought by operators in other European countries and the Middle East. Here again, CDE has made a tranche of improvements, including changes to the design of the logwasher to increase its efficiency and durability.

“Customers are finding that material from quarries which they would previously have considered as waste can now be turned into useful sand and aggregate,” says Walker. “It’s a way of conserving resources.”

The Evowash on the stand is a concept machine which will be tested by one of CDE’s customers based locally to the firm in Northern Ireland. The aim is to start producing them by the end of the year.

Before the new Evowash sand washing plant was installed, Wopfinger were working two shifts at Eggendorf to meet the capacity requirements of the ready mix concrete plant located at the sand and gravel pit. This has now been reduced to one shift as a result of both the quality and quantity of the wa
