By far the greater number of crusher applications involve feeds which are either graded (a mixture of large, medium, and small particles), or sized to a top dimension well within the effective receiving-opening dimension of the crusher.

The moving jaw moves back and forward against the fixed jaw, and material fed from the top of the machine is compressed between the two, breaking it into smaller pieces. As the moving jaw moves away from the fixed jaw, the crushed material is discharged from the crusher at the bottom, with the size of the ejected material determined by the gap …

Quarry rock of 12 in. maximum size is to be handled in a two-stage crusher plant at the rate of 70 tons per hour. The maximum size of output is to be 1½ in., and separation of materials over 1 in. size and the minus 1 in. in the output is required. Select a jaw crusher like those included in this table.

How you select your primary crusher will be based on factors like moisture content, maximum rock lump size, material density SG, abrasion index, degradability and it being prone to dusting or not. The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 …

Once the material reaches the desired size, it exits the crusher through the discharge opening at the bottom.

The narrower bottom opening of the crushing chamber is used to size the discharge material. A toggle plate and tension rods hold the pitman tight near the bottom of the moving swing jaw. The toggle plate is designed to …

Crusher Discharge Product Size & Shape. A striking feature of the non-choking concave, is the character of the product. So far we have been dealing with crushers whose eccentric speeds are low enough to permit the material to fall, with each receding stroke of the active crushing member, the full distance allowed by the close CSS and …

Selecting a crusher that is too narrow compared to the size of the incoming feed can result in the bridging of the feed material across the crusher opening. When this occurs, once again, throughput …

The selection of the best jaw crusher for your application will naturally be governed by the particle size, volume, and properties of your bulk material, along with the desired particle size and quantity of the final sample. The size of the jaw plates limits the particle size capacity and determines the size of the feed opening.

Crusher manufacturers publish grid charts, particle size cumulative distribution curves, and/or product size distribution tables to help predict the gradation of the crusher product. These charts, curves, and tables give the percentages passing or retained on standard size screens for each given setting of the crusher.

Cone crusher basics in 4 minutes. This is the starting point for understanding how cone crushers work – and how they can make your mine or quarry more productive. Elsewhere on the site you can find detailed information about all aspects of crushing and screening, but to make sense of these it helps to understand the basics of cone crushing.

y, reduced energy consumption and lower operating costs. With the two-machines-in-one concept, combining a crusher and a screen, the ERC 22-20 has a compact design tha. n, installation and maintenance.Flexible machine settingThe crushing jaw of the ERC 22-20 features a patented fully hydraulic ga. setting/retraction system with a wide gap ...

Jaw Crushers typically have a reduction ratio of 6:1, which means a 30" feed will be reduced down to 5" at the smallest size. The product size can be adjusted by …

The width of the discharge opening dictates the size of a crusher's product output. The size of a crusher's product output can be varied by raising or lowering the upper casing.

The maximum feed size for a primary jaw crusher depends on the machine's capacity and the material being crushed. Generally, the feed size should be less than 80% of the crusher's opening size.

90- passing the closed-side feed opening. Some people look at 80% of the open side as well and select the smaller of the two. 40-60% passing the midpoint. 0-10% passing the closed-side setting. A well-graded feed to the Cone Crusher. You want to match the entire feed gradation, not just the feed size, so that you utilize the entire …

For example, consider a crusher set to turn out a product 70% of which will pass a 5/8″ square opening, and in closed circuit with a screen which is equipped to remove the minus 3/4″ product. The curve …

It also has a narrower feed opening and a longer parallel section at the discharge, and delivers a product of ca. 0.3–2.0 cm. Contemporary secondary ( Figure 6.9 (c)) and tertiary ( Figure 6.9 (d)) cone crusher designs have evolved and geometry varies depending on the ore type, feed rate, and feed and product particle size.

The feed size, which often varies from small, fine pebbles to larger rocks up to 80 centimeters in diameter, greatly determines the crusher's throughput. Matching the feed size to the jaw opening ensures maximum efficiency – for mining operations.

Screening equipment is commonly used to size and separate material throughout the production process. Screens used ahead of a primary crusher can remove fine material, like abrasive stone or sand, which can cause wear and tear on the crusher's liners. They can also keep material that is already to size from entering the crusher feed, which …
