There are many aspects to be considered when selecting a cone crusher chamber profile to best suit your needs. An inadequate liner profile can lead to increased downtime through excess liner wear, low efficiency and, in some situations, even physical damage to the Mill Liners Foundry.
It is essential to have information that can support your decisions in order to be sure of the appropriateness and implementation of the liner profile. Let's look at five important points you need to know and why. Get optimum capacity and maximum wear-life of wear parts by considering these points from the perspective of your production and circuit. These aspects should not be considered the sole reason for selecting a liner.
There are many liners available for fine and coarse feeds. But which one you select will depend on a number of factors. The primary factor to consider in Cone Shredder Parts selection is the feed.
Grading of feed
Feed must be properly graded, with no gaps in the distribution of size. This usually means that the different sizes of the feed material need to be evenly distributed until the size that is maximum. Fines, such as less than 0-4mm, must be removed prior to feeding the crusher. This is called packing. It is result of force overload and is also known as adjustment ring movement. There are some differences between types of product, and Nordberg GP Secondary cone crushers, for instance, can take care of a certain amount of fines in the feed because of their vertically steep cavity and their adjustable stroke length.
A general rule of thumb:
Feed material that is excessively large can reduce the capacity and cause wear and tear on the lines.
The insufficient size of the feed to the cavity will increase the wear of the bottom part of the liners and may cause poor utilization of the wear parts.
Adjustment of the crusher (CSS).
The closed side setting (CSS) defines the reduction ratio in cone crushers. It also is a major influence on product quality, capacity, and power draw. The closed side setting is determined from the bottom of the mantle to the bottom of the bowl liner at their closest point in the gyrating cycle.
CSS should be near the required product. If the adjustment ring is moved over the main frame the adjustment will be too small. This blog post provides 12 tips to maximize the productivity of your cone crusher. In summary, larger settings will see the size of the product and capacity increase, while power draw decreases.
Feed type
The characteristics of the feed material such as the bulk density, gradation clay content, and moisture and crushability can have a major impact on the crusher's capacity.
For example, when the crushability of feed material changes from 40% to 20%, secondary and tertiary crushing load rise. The strain on closed circuits increases as the harder material Shredder Parts makes the product more coarse. The material's hardness causes the KW/ton product to increase. This kind of case is an example of the importance of liner materials. Different types of manganese alloys have been developed to match various feed materials.
Grading of the desired product
This is done in combination with the CSS (Crushing adjustment). To get the desired grade of product You adjust the crushing adjustments like CSS. For instance the Metso MX Multi-Action cone crusher includes a variety of other parameters that allow you to fine-tune the process of grading. This is taken into consideration alongside other factors when choosing the crusher in the first place, but it is also an important thing to consider in order to optimize your plant. It might be that the tertiary crushing plant is overloading and changing the liner of the secondary crusher reduces the load without significant changes to the process.
Operating speed of crushers (RPM).
A faster speed is likely to produce a more attractive product structure, as well as a more attractive shape for the product. Cone crushers are able to operate at a lower speed in order to increase cavity volumetric throughput. Additionally, the product gradation curve can also be altered to create smaller particles. It is possible to adjust the crusher's operation speed by altering the diameter of the crusher and also the motor sheaves.
There are numerous cavities for cone crushers. Each cavity has a different opening as well as setting range. Based on the size of feed as well as the setting and application you will be able to choose the appropriate cavity. It is crucial to keep in mind that the crusher is one part of the crushing system. The performance of the crusher is contingent on the operation of all parts of the crushing system, which includes screens, feeders electric motors, and drive components. To make the most of your manufacturing, be aware of all components.
