In the double roll crusher the feed is distributed by a feeder over the entire roll width. The material is drawn into the crushing gap by appropriately shaped teeth projecting from the rolls. For special applications, teeth of different heights are available at option. The anticipated maximum feed size determines the roll diameter. The size of the desired product can be fixed by the adjustable gap width between tip and bottom of tooth. The throughput rate is a function of roll width, gap width and peripheral speed. Both swings systems are carried in the base frame. The crusher rolls are hollow cylinders with headwalls and bearing shafts. Webs fitted to the roll body parallel to the cylinder axis provide for additional securing of the crushing shells. The bearing journals run in self aligning roller bearings and are protected against dust by shaft sealing and labyrinth rings. Forces generated during crushing are transmitted via the bearing housings and absorbed by the swing retaining frame direct. The gap setting can be adjusted by way of a spindle with threaded sleeve. This adjusting device is normally combined with the mechanical overload protection. Each crusher roll is driven by a fly-wheel type pulley which serves at the same time as a V-belt pulley. The drive is installed vertically underneath the pulley. This arrangement eliminates re-tensioning of the V-belts and re-locating of the feeder with advancing wear of the crushing shells. The practical application of roller crushers for a multitude of duties has resulted in the development of a standard machine which, on request, can be modified to a special type of equipment for given comminution tasks. Special Characteristic features: Low machine weight due to the double swing system. No transmission into the foundation of the forces generated during the reduction process. Counter balancing by retraction of the crusher rolls. No re-location of the feeder required, not even in case of pronounced wear. Easy replacement of the crushing shells and simple removal of the crusher rolls. Effective protection of the bearings against dust and other contaminations. Vertical arrangements of the drive which eliminates the necessity of V-belt tensioning upon changes in the gap width or in case of overload. Application: Lignite coal Coal Salts Calcareous marl Coke Dolomite Lime stone Sintered material hot or cold
