The Dodge jaw crusher has a variable feed area and a fixed discharge area which leads to choking of the crusher and hence is used only for laboratory purposes and not for heavy-duty operations. The jaw crusher is usually made of cast steel because it is such a heavy-duty machine. Its outer frame is generally made of cast iron or steel.
Choke feeding a cone crusher is a method used to ensure that the crushing chamber is always full of material, allowing it to operate at its most efficient and productive capacity.
Cone crushers work at their best when the chamber is full and there is a constant feed of material. In many situations this is not the case. Feeds vary for many reasons such as, poor recovery …

below bunkers, for the connecting of shafts in tunnels under open stocks, or before the crusher for regular and continuous feeding. Since vibrating feeders are connected to the bunker or bulk material, an uninterrupted feed is provided to the next item of machinery in the line. This type of feed is most suitable when there is a need for ...
For a very large jaw crusher or a gyratory crusher, it can take nine months. Source: Jim Redpath; The desired grizzly opening for an underground jaw crusher is equal to 80% of the gape of the crusher. Source: Jack de la Vergne; The maximum feed size for a jaw crusher should be about 85% of the gape. Source: Arthur Taggart
In the following, we will share with you how to get your cone crusher a correct feeding so as to improve the output capacity and meet with the nominated as well. 1. Choke …
During the design stage, whether a new plant or plant extension or replacement crusher is being planned, careful consideration is required to the design of the feeding arrangement. Material …
The parameters used in the basic design of a gyratory crusher are nip angle, feed rate, feed opening, closed-side setting, work index, and horsepower. The combination of the nip angle, feed opening, and closed-side setting determine the length of the crushing chamber and indirectly the length of the main shaft. The crusher manufacturer
1. Choke feed level for GP secondary crusher is at the level of the mantle fixing nut 2. Choke feed level for GP fine crusher is max 1 meter above the top bearing arrangement • The feed must be distributed evenly 360° across the crushing chamber. Uneven feed distribution may cause unbalanced crushing forces and uneven wearing in the GP concave.
It keeps the crusher feed cavity full for best choke feeding. Here is cone crusher arranged with a Level Sensor interlocked with the feed conveyor. 911 Metallurgist is a trusted resource for practical insights, solutions, and support in mineral processing engineering, helping industry professionals succeed with proven expertise. | Choke Feed a ...
The best way to ensure optimal liner life is to choke feed your Cone Crusher. Choke feeding allows a full chamber with material on top to help force the material in the chamber through. Choke ...
"Fines in the crusher feed" is defined as material entering the top of the crusher, which is already equal to or smaller than the crusher's closed-side discharge setting. As a rule of thumb, the maximum number of fines in the crusher feed should not exceed 25 percent for secondary crushers or 10 percent for tertiary crushers.
Uniform distribution of feed material around the cone crusher inlet is a good practice. This allows production of a consistent product, as well as efficient, reliable operation of the crusher. Choke-feeding is important for cone crushers because it maintains a good particle shape by facilitating an inter-particle crushing action.
The key is to match the crusher throughput capacity with the feed capacity, which can easily be done with the agile cone crushers. Bridging. Description: Blocking occurs when a piece of material is too large to enter the chamber and gets stuck at the entrance. Bridging is a subtly different problem, and can often be trickier to resolve.
Foremost, material like aggregate, concrete, or asphalt should be sized appropriately before being fed into a portable crushing plant. If material is too large, it could lead to jamming or bridging in the hopper, impactor, or jaw …
application people is that the crusher must have an adequate amount of evenly distributed feed. Figure 8 shows the effect of poor and good feed distribution. If the feed is correct, the crusher will have maximum produc- tivity (highest average crushing force) for minimum mechanical stress. A crusher normally cannot be properly fed from a vibrat-
It is not always possible to feed the plant in this manner; a smooth flow of feed to the primary crusher is the exception, rather than the rule; therefore, if we are to smooth out the flow in the plant itself we must have elasticity in our flow line, and the logical way to obtain it is to provide surge storage ahead of each crushing stage. ...
The feed drop point needs to be aligned with the center point of the cone crusher feed port. When feeding, it is best to use a vertical guide plate to guide the feed drop point to the center of the cone crusher feed port. Otherwise, once the drop point is not at the center, one side of the crushing cavity is full of material while the other ...
The ore is to be broken down in a jaw crusher to pass through a 11.5 cm screen. The undersize is scalped before feeding to the jaw crusher. Assuming the maximum feed rate is maintained at 30 t/h and the shapes of feed and product are the same and the crusher set is 10 cm, estimate the size of jaw crusher required and the production rate.

The optimal arrangement for a cone crusher is to choke feed it with a non-segregated feed. This will help the crusher run more smoothly by lowering both power and pressure peaks and improving overall performance. Choke feeding is about maintaining a constantly high level of evenly distributed material in the feed hopper. The recommended level ...
The main purpose of a Vibrating Grizzly Feeder is to feed a primary crusher in a primary application. Vibrating Grizzly Feeders reduce the amount of material going into the crusher by scalping out the product size ahead of the crusher. This reduces the size of …
The effect of feed chute design on tertiary cone crusher performance at the Sarcheshmeh copper complex was studied by an in-house developed DEM software called KMPC DEM ©. To simulate the overall crushing circuit, the multi-geometry procedure by improving the routines of object files importing into the simulation environment was implemented in DEM codes.
If the ore feed to any gyratory or jaw crusher consisted entirely of large cubes or spheres of a size that would just barely enter the crushing chamber, the crusher could not be expected to produce anything like its normal rated capacity because the upper part of the crusher could not shatter the large pieces enough to keep the rest of the ...
