FOUR HIGH-TECH HAZEMAG IMPACTORS FOR THE SÜDWESTDEUTSCHE SALZWERKE

The Südwestdeutsche Salzwerke, Germany, have recently installed a complete new underground rock salt (NaCl) processing plant, at the centre of which are 4 high-tech impactors supplied by HAZEMAG & EPR GmbH, Dülmen, Germany.

The concept for the processing plant was evolved in close consultation with the Technical University at Aachen. The plant comprises 2 production lines, each with a two-stage crushing system. The 1st crushing stage is a selective crushing process, and is effected by HAZEMAG impactors Type AP-SAH 1020. Thanks to the selective impact crushing, the rock salt is reduced to a finer granulation than that of the accompanying clay, stones and anhydrite, allowing the salt to be separated without problem in the downstream screening unit. This combination of selective crushing and screening results in a salt of very high purity.
Secondary crushing is carried out by HAZEMAG impactors, Type AP-SAH 1010, in which the generation of unmarketable salt dust is kept to a minimum.
The HAZEMAG impactors are equipped with an "intelligent" control system, comprising hydraulic gap setting and integrated speed control facilities, which permits optimum alignment in response to any changes in feed material characteristics. Thanks to the automatic control of the HAZEMAG impactors, the result is a product of unvarying high quality and purity. In addition, the high costs involved in the necessary disposal of unwanted waste material underground are reduced to a minimum.

SUCCESS FOR HAZEMAG'S NEW STYLE ROTOR AT UK QUARRIES

HAZEMAG & EPR GmbH has supplied TARMAC with its latest GSK-type rotor as a replacement rotor for a HAZEMAG AP5Br Impactor, which has been operating for many years at the company's Stancombe Quarry. Built and delivered in just 5 months, the new style rotor has been installed under the watchful eye of an experienced HAZEMAG engineer and the upgraded Impactor now has the capacity to handle limestone of up to 1000mm edge length at rates up to 450 tonnes per hour. It is the second GSK-type rotor to be supplied into the UK, the first being supplied to HANSON'S Tytherington Quarry, also retro-fitted as a replacement rotor for a HAZEMAG AP5Br Impactor.

Since its launch, the GSK-type rotor, has proved a resounding success, in total 13 orders have been secured, 8 of which have been supplied as retro-fits to existing HAZEMAG and other impactors employed on primary and secondary applications.

The GSK-type rotor combines the crushing qualities of the Hazemag S-type rotor and the K-type rotor. It is a welded cast design with mechanically-clamped blow bars and is designed to give a higher degree of blow bar utilisation. Quick and simple blow bar turning / changing in both the axial and radial direction is possible with the provision of specially designed blow bar changing devices. The system enables radial blow bars to be turned through two axes without any setting down.

In contrast to the K-type (open disc) rotor, this new rotor can be used for primary crushing applications with no restrictions whatsoever. Furthermore, time-consuming cutting of bolts during blow bar changing operations is not necessary.

Much of the success of this new generation rotor is down to its efficiency and high degree of availability which results in an extremely favourable cost / performance ratio.

Both HANSON and TARMAC have agreed inspection contracts with HAZEMAG for their upgraded impactors. Such contracts cover the detailed inspections of the machines and plant at fixed intervals as determined by the operating conditions according to prior agreement. The preventative and conditional maintenance carried out by highly-trained and experienced personnel from HAZEMAG & EPR GmbH greatly contribute to the avoidance of expensive repairs. By the early recognition of potential danger areas and problems, damage to machines with consequent downtime and production loss can be reduced to a minimum.
