Cone crusher product shape control

Cone crusher crushing equipment as often, their broken product shape is the main indicator of the quality of production. In particular, some applications require a cone crusher product needle tabular grains to meet certain standards, so crushed product particle shape control is necessary.

Cone crusher is widely used in metallurgy, mining, water and other buildings, and played a key role in the respective production process. Broken main object machine for ore material, its particle shape (geometry of the material particles) is the main indicator broken product quality evaluation, usually can be divided into a cubic shape and flakiness.

Elongated particles in crushed product share of the mass fraction of needle chip rate, is to evaluate the crushed product grain shape of quantitative indicators. Affect the rate of needle factors include ore type, type crushers, crushing stage, feed particle size, closed side discharge opening size ,and the amount of material fed into the eccentric shaft speed.

In the construction sector, the increase in concrete aggregate flakiness particles can lead to building overall compressive strength decline and increase in cement consumption in the building process; likewise, in the asphalt mix, the particles will increase flakiness resulting in decreased overall density of the mixture and the compressive and tensile strength. Thus, the needle piece rate for crusher product quality plays an important role.
