Types of Crushing Equipment models

Crushing equipment is used to reduce the size of material into much smaller pieces. The equipment is designed with heavy plates or jaws used to apply pressure to whatever material has been fed into the chamber. The crusher equipment is predominantly used by the mining industry to carry out operations like the crushing of rocks, building materials, solid waste, etc. Modern crusher models adopt self-drive mode, possess advanced technology, and complete function. The newer models use a direct drive system for optimum fuel efficiency and low operating costs and include several user-friendly features. This ensures that they’re both simple to operate, and easy to maintain. Mobility and versatility have been key factors in the development of new models, with many companies also offering new options of hybrid drive systems.

The static plants, which take days to set up and dismantle, have slowly become redundant with the advent of portable devices with higher capacity. There is a growing requirement of aggregated equipment in the coming years to meet the demand from the construction and infrastructure sector. This anticipates an increased demand for crushers. In the construction sector, growth in roads, railways, irrigation, and other infra projects will drive the material processing equipment industry. The rising use of artificial sand for construction work after the ban on river sand mining is expected to have a positive impact on the growth of the crushing equipment market. The coal sector is set to grow rapidly for the next few years. Different types of crusher models are available for different applications, each of them is discussed below.

Different types of crusher equipments

Jaw crusher featuring hydraulic discharge setting adjustment

Modern jaw crushers feature hydraulic discharge setting adjustment, adjust-on-the-fly chamber clearing in the event the site loses power (once power is restored) and hydraulic relief for overload events with auto-reset. Machines have an aggressive nip angle that provides consistent crushing throughout the entire crushing chamber, which leads to increased production and less downtime on maintenance. Hydraulic separation and individual lifting of shells are a trend that creates a better environment for any workers on-site working with the equipment. The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws. Primary jaw crushers are typical of the square opening design, and secondary jaw crushers are of the rectangular opening design. Jaw Crushers can be used in stationary, wheeled portable and track-mounted locations. The Jaw Crusher is well suited for a variety of applications, including rock quarries, sand and gravel, mining, construction and demolition recycling, construction aggregates, road and railway construction.
