If a single-stage reduction is required, then depending on the feed-to-product-size ratio of reduction, either a Single or Double Roll Crusher can be selected. Regardless of the crusher type selected, Roll Crushers allow for the material to fracture along naturally occurring cleavage lines, which helps with minimizing fines generation.
Crushers are machines used to reduce the size of rocks, stones and ore. They are often utilized in aggregates production, construction material recycling and in mining …
When larger feed sizes require up to a 6:1 ratio of reduction to achieve the final product, a Triple Roll Crusher should be chosen due to the inherent design, which allows the larger feed sizes to be readily grabbed in the large throat opening between the top (primary) roll and crushing plate.

However this type of crusher is not commonly used due to its tendency to choke. The larger opening at the top enables it to take very large feed and to effect a large size reduction. This crusher is usually made in smaller sizes than the Blake-Jaw Crusher due to high fluctuating stresses that are produced in the members of the machine.

Industrial crushers reduce large rocks, ore or waste materials to smaller sizes by impact or pressure to fracture or deform the material. During the primary crushing operation, boulder size feeds from 20 to 100 in. are reduced to secondary crusher sizes of 1 to 20 in. or mill feed size of .5 to 3 in.
However, size reduction equipment are not only used in food processing industries. It is also widely used in construction industries. Common examples are; Jaw crusher and Gyratory crusher. Jaw crushers: Jaw crushers are used to bring very big particle into reasonably small size of crushing of ores; lime, stone etc. The moving jaw …
4.2. Criteria for Size Reduction Crushers and grinders are used for size reduction (also known as comminution). An ideal crusher or grinder should have a large capacity, consume as little energy as possible and the product particles should practically have the same size. In practice all these criteria are hardly met.
Jaw Crushers 7 The BB 50 is designed for a very efficient and convenient size reduction pro-cess. The variable speed can be set between 550 and 950 min-1 to adapt the crushing process to sample requirements. The possibility to reverse the rotat- ing direction is helpful if too much sample material has been fed to the crusher causing it to block.
A stone crusher is a type of size reduction equipment designed to break down or compress large stones. Known for their high output and significant crushing capacity, stone crushers are used both as primary crushers and in secondary or tertiary stages of crushing.
What Impact Crusher Do I Need? Selecting an ideal impact crusher for your size reduction project is determined by the industry you are in, the project scope, and the final product size you desire. In the building and construction industry, an impact crusher is used to create smaller rock particles such as sand and gravel.
Finished particle size is determined by a combination of the following: screen (or bar grate) size, shaft speed, hammer size, and hammer configuration. For example, a fast shaft speed, small screen and large number of hammers typically produces a fine end product. Conversely, a larger screen, fewer
