ESSROC – ITALCEMENTI orders a HAZEMAG primary crushing plant

Friday, September 28th, 2007

The ESSROC CEMENT CORPORATION of Nazareth/PA; USA, a member of the ITALCEMENTI Group, has placed an order with HAZEMAG & EPR GmbH in Dülmen for a 1,000 tons/h primary crushing plant. The plant comprises an apron feeder and single-rotor AP-PMH 2022 primary impactor, and is intended to replace an existing system.
The apron feeder with under-mounted scraper chain conveyor for spillage material is equipped with a variable-speed drive, which allows the conveying rate to be adjusted immediately in response to changing operating conditions.
The impactor, which is fitted with a grinding path, can handle feed material of up to 1 m edge length, to generate a product 97 % <100 mm in a single pass. The grinding path and impact aprons are provided with an electro-hydraulic gap setting adjustment system. The impactor rotor is a GSK-type rotor with a diameter of 2,000 mm and a width of 2,200 mm. This rugged rotor is of welded cast steel construction and is characterised by a particularly high mass moment of inertia, which means that any material flow peaks which may arise can be handled without difficulty. The plant is due for delivery in July, 2008. For further information visit:
