All You Need To Know About Cone Crushers

The right maintenance requirements and operational parameters cone crushers are the best way to ensure your business produces aggregate cost-effectively. This is also something your employees need to be aware of, especially when you’re looking for cone crushers for sale. Here’s a list of some tips that can help you maximize cone crusher productivity.

Working at a Compatible Closed-side Discharge Setting

Operating cone crushers at a consistent closed-side discharge is the best way to gain a consistent combined quality, quantity and uniformity. It is also the best way to achieve a balanced circuit in your system. By doing so, it will result in more over-sized aggregate and far less production – especially if the cone crusher is operated at a wide-than-optimum setting even if it’s on a temporary basis.

Working at a Consistent Choke Fed Cavity Level

The cavity levels during the shift of the cone crusher will determine the shape consistency and production rates’ consistency. Low cavity, or half cavity, levels will always result in a much coarser in the product gradation. At this level, the product particles flatter and become more elongated, so it is essential that you have the right choke-fed cavity level to increase cone crusher’s throughput tonnage to achieve a more cubical product.

Ensure the Feed is evenly and vertically Distributed

Make sure that the incoming feed material is directed and distributed vertically into the centre of the cone crusher – by so doing, all sides of the crushing cavity stay evenly filled. Remember that if the feed is directed anywhere else other than the centre, it will result in over-sized products, flatter and elongated product particles with lower crusher throughput tonnage.

Minimize Surge Loading for Better and Efficient Circuit

Surge loading has a negative impact and effect on the production of any crusher, including cone crushers. The use of surge charge and feed hoppers as well as varying speed feeding devices can provide a better and more consistent feed control to the cone crusher. As a result, the cone crusher will be able to operate at a compatible and solid cavity level.

Know the Cone Crusher’s Design Limitations

Each cone crusher has design limitations and it is crucial that you’re familiar with these. They include the volume limit, horsepower limitations and the crushing for limit. Let’s look at these:

Volumetric Limit

Every crushing cavity has a volume limit that dictates the maximum throughput as well as the choke-feed crusher operating at a particular volume limit. When the feed material overflows the top of the cone crusher, the volume limit is exceeded.

Horsepower Limit

Cone crushers are made to operate at a certain maximum power capacity. The power draw will increase as the feed rate increases and end up with the feed material will be crushed finely. Whenever the crusher extracts more power than it is assessed for, the horsepower limit will be exceeded.

Crushing Force Limit

Finally, we need to look at the crushing force limit of the crusher. Much like the horsepower limit, crushing forces limit will be put in the mantle and the bowl liner will increase as the feed rate increases as well as when the feed material is crushed finer. The cone crushers crushing force limit will indicate it’s been crossed when the adaptation ring bounces, bumps, jumps, moves, or wiggles on the top of the main frame.
