Jan 01, 2016 Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing is employed.
Roll Crushers are compression type crushers, and were once widely used in mining. They have, within the last 10 or so years, fallen into dis-favor among mining and processing companies. The probable reason is because the large mines require very large crushed product output with minimal cost, makes the roll crusher uncompetitive.

Oct 04, 2017 The new crusher features a particularly flat and robust design and high throughputs of up to 3,000 tons per hour, enabling it to process hard rock and ores efficiently and economically in underground mining operations. As the centerpiece of a mobile or semi- mobile system the eccentric roll crusher also enhances cost efficiency in surface mining.
The bottom of the Pennsylvania Crusher reversible impactor is open and the sized material passes through almost instantaneously. Liberal clearance between hammers and the breaker blocks eliminates attrition and crushing is by impact only. Pennsylvania Crusher single roll crushers reduce large input by a combination of shear, impact and compression.
Apr 23, 2016 In conventional mining, double-roll crushers are sometimes referred to as mineral sizers since they reduce the size of the largest chunks without pulverizing the smaller particles. These types of crushers or sizers are commonly used in reducing the top-size of soft or sticky material, such as limestone or lignite brown coal.
