Crushing Plant Design and Layout Considerations
The life of the mine is a key element in the design of any crushing plant. Short-term mine lives (three to eight years) require a very careful approach to design, layout and construction. Since the crushing plant's structure and enclosure can represent the largest single cost element in a primary crushing plant, it is imperative to optimize ...

Dynamics in double roll crushers
Abstract. Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute medium-hard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.

What Type of Crusher Is Best for Primary Crushing?
Roll Crushers are compression-type machines, so output gradation is controlled mainly through the gap setting between the rolls. A wider setting results in a coarser product. A wider setting also provides greater throughput. Single Roll Crushers feature a low-speed crushing roll that crushes material against a curved crushing plate.
