Essentially, material is reduced in size by squeezing the material until it breaks. Specifically, the material is compressed between a moving piece of steel, the mantle, and a stationary piece of steel, the bowl liner. The final product''s size is determined by the closedside gap setting between the two crushing members at the bottom.
what is crusher closed size setting sagarhotel . Crusher Wikipedia. A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw
The widest distance is known as the open side setting (OSS) and the narrowest, the closed side setting (CSS). These settings are important. The OSS is the largest distance between the concave and the mantle at the bottom of the crusher, so it determines the largest particle size of the outgoing product.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
4. Check the closed side setting. The setting should be close to the required product. The setting is too small if the adjustment ring is moving on the main frame (ring bounce). • Larger setting > Product size increases • Larger setting > Capacity increases • Larger setting > Power draw decreases 5. Check the crusher operating speed.

Jaw Crushers. Jaw Crushers are used to reduce the size of many different types of materials in many appliions. The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a doubletoggle Jaw Crusher. Introduced in 1906, McLanahan''s Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers.

Dec 05, 2016 · An example of the effect that crusher setting has on the product gradation is as follows: If the target crusher setting is 3/8 in. (10 mm) but the setting is not checked and it wears open to 1/2 in. (13 mm), then the end result is a 15 percent decrease in the minus 3/8in. (10 mm) material size. This is a substantial decrease in productivity.
crusher Whenever a jaw crusher is off and at rest (stopped), it will remain in the open position at its openside setting (OSS). However, the adjustment of your crusher is performed at its closedside setting (CSS). OSS is measured while the crusher is stopped. CSS is calculated by deducting a certain amount (the average stroke) from the OSS.
The three main types of crushers are the cone crusher, the jaw crusher, and the impact crusher. Make sure you understand all of the differences between these kinds before choosing one for your project. Regardless of which type of machine you choose, you should be
Typically crusher run is available in sizes from 3/4″ to a #200 sieve.

A Cone Crusher will deliver a 4:1 to 6:1 reduction ratio. As we set the closed side setting tighter to create a finer output, we also reduce the volume or throughput capacity of the machine. Generally speaking, multiplying the closed side setting by two is a good guide to the top size of the gradation exiting the machine.
Jaw crushers are a popular alternative to primary gyratory crushers, since they can process large amounts of hard material efficiently. Due to their smaller physical size, jaw crushers are also ideal for tight spaces, such as underground mining and mobile crushing appliions.
