BSW Machinery launches 20% lighter polypropylene woven bag 02 February 2016
Austria: BSW Machinery has presented a new type of woven polypropylene (PP) bag that is 20% lighter than comparable bags. Using its Light & Strong (LS) technology BSW has produced 64g bags that they say outperformed standard 80g bags commonly used in the cement industry in drop tests. Key elements of the LS technology include advanced extrusion technology for higher tape tenacity and indexed micro perforation.
The Vienna-based subsidiary of Windmöller & Hölscher has implemented new processing technology on BSW's tape extrusion line tiraTex to achieve higher strength without compromising elasticity. Tenacity values of 7g/den can be achieved with elongation at break values ranging be-tween 25% and 30% using standard PP grades commonly used in industry. The processing characteristics can be maintained at high outputs and production speeds of 500m/min or more.
The LS bags also have higher edge strength by protecting edges and other areas through indexed perforation. The perforation is disengaged whenever vulnerable sections of bag material are passing through the bag conversion machine. Synchronization ensures that the unperforated areas are matched to the print on the bag and are placed such that in the final bag the critical zones are built from un-perforated material.
Korfez announces recent orders in Turkey 02 February 2016
Turkey: KORFEZ ENG. has announced a series of contracts for cement mill components in Turkey. No values for the orders or client details were disclosed.
The cement and mining industries casing manufacturer has received an order to convert a cement mill from two grinding chambers to one by means of a new mill shell lining system. The new WAVE 35/55 mill shell lining will be installed in a cement mill with a diameter of 4.4m. This plate profile leads to an optimal fine grinding in the whole grinding compartment. This is the third major order for Korfez within two years from a private cement company north of Istanbul.
In January 2016 Korfez signed a contract to convert two cement mills at another cement plant near Istanbul. The two existing two-chamber cement mills will be modified to mono-chamber mills. The scope of supply includes the reconstruction of the complete mill inlet with a new step chute, a new wave mill shell lining system in high chromium alloyed steel casting and a new complete discharge diaphragm. Delivery and installation is planned for April - May 2016.
Finally, Korfez has signed an order to deliver a new shell lining system for another Turkish cement producer. The scope of the order is a complete replacement of a wear shell lining for a single-compartment mill Ø4.0m and 14.5m effective grinding length, the mill discharge and complete new manhole covers in modified execution. The complete lining is as a wave profile type: WAVE 35/50 in a highly wear-resistant steel castings with 27% chromium content. The complete contract scope is to be completed and delivered in six weeks.
Egypt: Suez Cement plans to spend US$77m to convert its Helwan and Torah cement plants to use coal and refuse derived fuel (RDF), according to local media. The Kattameya and Suez cement plants were converted in 2015.
The company intends to start the conversion process in February 2016 at Helwan and July 2016 at Torah. The upgrade is expected to take 12 - 18 months. Subsequently both plants would use 70% coal for their energy. Helwan Cement will supplement this with 20 – 25% RDF and 5% natural gas. Torah Cement will use 30% heavy fuel oil. These conversions are expected to reduce the company's operating costs.
