The crushing chamber, or crushing cavity, is the confined space within the cone crusher where the actual size reduction of the feed material takes place. The chamber geometry, along with the configuration of the mantle and concave, directly influences the crusher's capacity, product gradation, power draw, and overall efficiency.
Measurement of the crusher's closed side setting varies depending on the jaw profile that is being used and has an impact on the crusher's capacity and product gradation. The following factors will enhance crusher capacity and performance:* Smaller closed side settings can be often used depending on application and production requirements.
reduction through the crusher and the end-product shape. Closed side setting (CSS) The closed side setting has a significant effect on the product gradation, capacity, and power draw of an MP Series™ cone crusher. The closed side setting is measured from the bottom of the mantle to the bottom of the bowl liner at their closest point during the
HP cone crusher at the lower end of its speed range will increase the chamber volumetric throughput and the product gradation curve can be altered to produce fewer fines. The allowed speed limits can be found in the ® HP Series cone crusher instruction manual. Before changing the speed of the crusher, consult product support
Crusher run is typically made of gneiss, granite, limestone, or trap rock. It may include recycled concrete or asphalt depending on the quarry. Strength and Load Bearing. The crushed stone particles, angularity, and dense gradation give the crusher run high compressive strength. Its California Bearing Ratio (CBR) typically ranges from 60-80%.
Too many shades of "sand" and also "crusher dust." Either supplier should be able to give gradations and moisture-density relations (i.e., Standard or Modified Proctor).
To maintain the maximum levels of capacity, gradation and cubical product, a CMB Cone Crusher must be choke fed at all times. The best way to keep a choke feed to the CMB Cone Crusher is with a surge bin or hopper and Feeder that are located prior to the crusher. Choke feeding is almost impossible to achieve without a hopper and Feeder.

Feed gradation should be stable (no gaps in feed). Too big feed material. Too small feed material. Note: Feed material characteristics such as gradation, bulk density, moisture, clay content, and crushability have a significant impact on the crusher capacity.

The gradation of the finished product can be very important. Most state DOTs have a specific gradation range that must be adhered to in order to meet the DOT requirements. The type of crusher you use can and will change the gradation of the material and the material quality.
The sand gradation is characterized by uniformity coefficient of host sand (C us) and grain size ratio (R d), which is defined as the ratio of the mean grain size of sand to that of fines. The effects of fines content (FC) and sand gradation on small strain shear modulus G 0 are analyzed from the experimental results.
From the test results of crusher dust, the following identifications are made. The grain size distribution of crusher dust shows that it consists of 92% of sand size and 4% of silt size …
For the primary crusher a jaw crusher will probably be most economical. A jaw crusher, like 2036 in the Jaw Crusher Table here above, would be able to take the maximum 12 in. size quarry stone but it would not have the …
The following factors will detract from crusher capacity and performance: 1. Sticky material in crusher feed. 2. Fines in crusher feed (smaller than crusher setting) exceeding 10% of crusher capacity. 3. Excessive feed moisture. 4. Feed segregation in crusher cavity. 5. Improper feed distribution around circumference of crusher cavity. 6. Lack ...

In addition, based on the standard gradation, a continuous gradation with a Talbot index of 0.4 was selected as gradation 4 for comparison [24]. In order to eliminate the particle size effect, the maximum particle size of the design sample is less than 1/5 of the diameter of the test container, and the maximum particle size is 15 mm ( Fig. 2 ).
gradation with greater percentage passing the closed-side setting. This is helpful in situations where the cone has the correct liner, but the crusher can't produce enough power to maintain a choke feed. Increasing the speed chokes the cone, producing more material of the proper gradation for better overall throughput. 1 4 Analyze crusher ...
