Once you've determined what material you'll be crushing, you'll need to choose which sort of crusher is best for you. Crushers of the compression type, such as a jaw crusher or a cone crusher, are often employed with abrasive materials. These machines break down rocks by compressing them between two surfaces, which crushes the rocks into smaller pieces.
Impact crushers, on the other hand, are designed to crush materials that are not conducive to being crushed by other types of crushers. For example, screeners and refiners use impact crushers to break down rock materials that would otherwise need to be screened or refined by other methods.
The choice of crusher will depend on several factors, including the type of material you're trying to crush, its size, and how much you can spend. If you have large quantities of small material to process, then an impact crusher may be the most efficient method. These machines are easy to operate and require little maintenance. However, they do produce some sparks when breaking rocks in contact with one another, so you’ll want to ensure that you have a clear area around where you’re operating your impact crusher.
If you plan to process materials that are larger than 35 mm (1.4 inches), then you’ll need a jaw or gyratory crusher.
The compression concept is used by jaw crushers, gyratory crushers, and cone crushers. The impact concept is then used by impact crushers. Jaw crushers are used mostly as primary crushers. They can be single- or double-headed, with either a horizontal or vertical shaft. Gyratory crushers are used for medium to high crushing duties where compaction is a problem. They have a rotating head that rocks back and forth like a gyroscope to break down material into smaller pieces. Cones are used as secondary or tertiary crushers. They usually have three cones that rotate around the central axis of the machine. Each cone has a hole in its center through which a ball is dropped. As the balls roll across the surface they hit each cone hard, causing them to rotate. The direction of rotation is such that the balls move from the outside toward the inside of the cone.
Impact crushers use an impacting member called an impeller or hammer to crush materials such as rock, ore, and coal. These machines use a large amount of energy because much of their operating cost is associated with the impact itself. Impact crushers can be single- or double-ended, with either a horizontal or vertical shaft. They range in size from small portable units for mining applications to huge structures used in quarrying operations.
The conventional crushing equipment with several variants and a high output is the jaw crusher. The PE jaw crusher is mostly used for primary crushing of different ores and raw materials, but it can also be used for fine crushing. PE jaw crushers come in a variety of sizes, with the most popular being the PE-750x1060, PE-600x900, and PE-150x250. These machines have a long service life because they use wear parts that are replaceable instead of irreplaceable metal components.
The impactor is another efficient primary crusher used for grinding minerals or rocks into smaller pieces by using an impact mechanism. This machine works on the same principle as a hammer: one rock is thrown against another to produce more crushed material than would otherwise be possible with a jaw crusher. Impactors are available in two main designs: single-stage and dual-stage. In the first case, the material is crushed from medium size to very small, while in the second case there is a possibility to increase the fineness of the product further by repeating the process twice or three times.
The gyratory crusher is a device that uses rotating cups or balls to crush materials such as rocks, ore, and minerals. These machines are designed to reduce the size of the material while lifting it out of the way so that other portions of the material can be crushed as well. This action repeats continuously until only small particles remain which can then be moved by a secondary crusher.
