Whilst up in Scotland doing some video work for the Scottish Resources Group I thought I couldn't leave the stills camera at home!

Re: Scottish Coal
The grinding efficiency can be improved by use of a vertical roller mill, while reducing the energy consumption and improving the
product quality. The disclosed cement clinker grinding apparatus comprises a closed circuit for conveying the ground material from the
vertical roller mill (21) to the external separator (28) by the bucket elevator (29), for classifying the conveyed material into coarse
powder and fine powder, and further for returning the classified coarse powder into the vertical roller mill (21). That is, a part of
the ground material conveyed by the bucket elevator (29) is divided by the distributing damper (32) and then directly returned to the
vertical roller mill (21). Since the ground material are not conveyed by air flow conveyance (i.e., air sweep), it is possible to
prevent an increase of power consumption of the suction fan (31). Further, since a part of the ground material is distributed by the
distributing damper and then further ground again by the vertical roller mill, it is possible to obtain an optimum particle size
distribution of the cement products, so that the cement quality can be improved.
vertical roller mill is a new kind of large scale power mill which is designedspecially to solve the problems of low capacity and high consumption ofindustry mills. With a decade of years research of mills, Vertical Roller Mill is designed and manufactured based on our advanced designidea, and in combination with the European technology and the marketdemand. It adopts reliable structure and reasonable process flow,integrated with drying ,milling, classifier , elevator. Especially ,itcan fully meets the requirement of clients in the high production ofpowder and its main technical and economy indicator reaches theinternational level.
Application:
Specialized for the high production of superfine pyrophyllite powder making in glass fiber industry;
Specialized for the high production of gangue powder making in coal industry;
Specialized for the high production of various of chemical raw material powder making in the chemical industry.

Re: Scottish Coal
Hi Klaus,
The Bucyrus/Terex RH120E weighs in around 260-280t and handles a 15m3 bucket, or in the case of one of the Scottish Coal machines a 17m3 backhoe bucket.
The 9350 is a 320t machine and in the Scottish Coal application handles a 17m3. The bucket on the Liebherrs have been designed to have the capacity but not the added width that comes with such a bucket to enable it to load the 777F without too much spillage of material over the side of the truck bodies.
regards
Paul

Re: Scottish Coal
Not sure Joe. The 17m3 on the Bucyrus is a bit too wide to load the 777Fs but is ok for rock. When they load over the back of a truck they are getting too much overspill with the wide bucket. Capacity is fine on them, 3 passes and they should fill a 777.
