Efficient use of cone crushers
A cone crusher is often used in the second to third crushing stage and operates according to the pressure crushing principle. It is suitable primarily for use in medium-hard to hard and abrasive natural stone and in mining applications. In the second and third crushing stage cone crushers produce a very high final grain quality.
Increasing demands on the final product make intelligent machines that support operators with their work necessary. Plants therefore become increasingly more complex, however, long periods of instruction for operators are often not possible in practice. As an innovative manufacturer of crushing and screen plants, KLEEMANN has therefore set itself the objective of adapting its machines to user requirements and of developing user-friendly elements.
The KLEEMANN design offers numerous different features that facilitate work for the operator. For example, the Continuous Feed System guarantees a continuous crusher load. This system monitors the crusher fill level with a sensor and automatically controls the supply of the feed material. The machine can also automatically adjust the crushing gap in an overload situation. The integrated overload system protects the crusher against uncrushable material such as wood or metal and also operates automatically.
As a general rule, operation of KLEEMANN plants is designed in a simple and intuitive manner. The control concept SPECTIVE allows the machines to be operated conveniently at a touch panel. All components and functions can be controlled comfortably from the ground. The standard series radio remote control even makes ergonomic operation from the excavator or wheel loader possible.
Our local contact partners provide you with comprehensive support for all applications and questions related to our products. Thanks to our closely-knit, global WIRTGEN GROUP network, we guarantee short reaction times and quick solutions. Original parts and accessories on site assure the high reliability and availability of the machines.
Do’s
Fill evenly and avoid running empty
A material layer should always be present in the feed hopper because this reduces wear. Avoid overfilling and ensure that filling is even because this guarantees a constant load and prevents serious fluctuations. Your process and plant run more stably.
Observe the maintenance and inspection intervals
Regular maintenance and observance of the inspection intervals increase plant availability and thus the productivity.
Monitor the process regularly during operation
Regular monitoring allows operators to detect overloads in good time and to adapt process parameters. Overfilling of hoppers must be avoided, also in the case of material return sections.
Prior to starting: check the process
Before using in a new application, you have to check whether the installed tool is suitable for the task and which crushing gap can be operated. Process simulation can provide support in this area.
Dont’s
Avoid loading wet and sticky feed material
This can lead to a blockage of the crushing process which, in turn, increases the risk of overloading and permanent damage to the crusher.
Observe the correct feed size
Feed sizes that are too large or too small can both have negative effects on the process and can damage the cone crusher. Select the tool to match the feed size and the final product and adapt the feed size to match the tool. Ensure that only material of the same type is loaded and avoid gap grading.
Adapt the processes in case of overload
Overloading of the crusher is characterised by strong movements on the bowl and by briquetted material on the crusher discharge conveyor. Prior to feeding, the feed material must be pre-crushed to make it smaller or fine material must be prescreened. If necessary, the crushing gap must be increased. An increase in speed can also have a positive effect.
Avoid fines
When fine material is fed in, tool wear and the crusher load is significantly higher than with prescreened feed material. Therefore activate the primary screening at the upstream jaw crusher or, alternatively, position a screen machine before the cone crusher to separate fine material.
