Jaw crusher is used for coarse crushing (feed size: 40 mm -50 mm; product size: 2 -10 mm). The crusher has a fixed jaw and a moving jaw pivoted at the top with the crushing faces made of manganese steel.
The jaw crusher will handle sticky,'or dirty feed better than the gyratory, there being no diaphragm below the crushing chamber on which such material can pack. Routine maintenance and repair jobs are generally more easily accomplished on the jaw crusher than on the gyratory. Major repairs are about a stand-off.
The crusher model ERC 25-25 selected for this purpose has a crushing roll measuring 2,500mm in diameter and width. The feed opening to the crushing chamber is 2,500mm wide and 1,230mm high (see table 1). Both the coarse and fine run-of-mine feed were processed, together with selected lumps of up to 5 tonnes. The equipment …
Primary crushers reduce large run-of-mine material, such as rocks and ore lumps, into smaller sizes for further processing downstream, whether that be transport to additional crushers or to a wet processing plant. It is the first stage in the crushing process that can sometimes include secondary, tertiary and even quaternary crushing stages, …

Double Roll Crusher Brochure. Typically used as secondary or tertiary crushers, McLanahan Double Roll Crushers provide a 4:1 reduction ratio and can be used following other McLanahan equipment, such as Feeder-Breakers, Rotary Breakers, primary DDC-Sizers, or Single Roll Crushers, when further reduction of primary crushed material is …
By comparing the results obtained from two crushers, it is found that the products sizes obtained by the roll crusher are much more uniform than those obtained by the jaw crusher.
The document summarizes information about a roll crusher supplied by ThyssenKrupp to Nordkalk in Sweden in 1988. The roll crusher has a throughput rate of 800 tons per hour and crushes limestone with a feed size of 90-250/300 mm to a product size of less than 150 mm. The crusher is powered by two 132 kW drives and uses shear and tensile forces to …

A critical review of the most typical designs of roll crushers and mills proposed by scientists, designers and inventors of the world's leading countries has been performed. The designs are ...
Jaw crushers and cone crushers are two of the most common types of stone crushers used in mining and construction. Both types of crushers use compressive force to break down rocks, but they have different advantages and disadvantages. Which is right for you? Read this article.
The roll crusher WB is used as a secondary and tertiary crusher. Depending on feed material and application – soft or hard, abrasive material – we have the right type of roll crusher. Depending on the requirements, the rolls are smooth or toothed. Due to its sturdy and simple construction, low energy consumption per ton produced, and simple ...
The single roll design is much more effective in reducing slabby material in comparison to jaw or gyratory crushers. When properly maintained, the "interrupted opening" between …
