Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are ...

The above signals are mostly time series data, while the sizer operating status can be assessed by the classification of the feed signal. The sizer operation signals differ when different materials enter the crushing cavity, therefore, the TSC method can be used to classify the crusher feed signals and thus identify harmful materials. 3.3.
