Types of Crushers: What You Need to Know
Cone crushers. Cone crushers are one of the main choices for secondary crushing. A cone crusher is a powerful machine that is used in large-scale industries for crushing various types of materials into smaller sizes. It works by applying pressure onto the material and squeezing it against a rotating mantle to create compression and force.

A fundamental model of an industrial-scale jaw crusher
Abstract. In this study, an analytical perspective is used to develop a fundamental model of a jaw crusher. Previously, jaw crushers were modelled in regard to certain aspects, for example, energy consumption (Legendre and Zevenhoven, 2014) or kinematics (Oduori et al., 2015). Approaches to date have been mainly property specific.

Considering Industrial Fan Noise | Air Solutions, Inc.
Values are given for the sound pressure levels of sounds commonly heard in our environment. When comparing noise levels, bear in mind that noise at 120 dBA or higher for an extended period of time can result in pain or potential hearing loss. Industrial fan noise levels range anywhere from 70 dBA to 90 dBA at 10 feet.

Advanced comminution modelling: Part 1 – Crushers☆
Crushing is usually more energy efficient, but this becomes less clear for very fine crushing in tertiary or later stages. Commonly used machines for large scale crushing include gyratory and twin roll crushers (for primary crushing) and high pressure grinding rolls (HPGR) and cone crushers (for secondary crushing).
