The crushers are particularly suited to aggregates, construction and demolition recycling, and site preparation.
The crushing and screening equipment manufacturer says the J4 builds on the robust features of its existing product range, with a line-up of features aimed at boosting productivity and offering enhanced durability across applications.
Designed to withstand the toughest conditions, the J4 delivers high production due to its jaw chamber design and enhanced material flow, the company says. The large 1060mm x 700mm jaw opening accommodates large feed sizes, contributing to higher production in material processing.
The material path is improved with the 1064mm x 4247mm grizzly pan feeder under the hopper that allows for better sizing of material with a variety of mesh options. Options of either a short pan feeder to suit the pre-screen or a double-deck grizzly pre-screen are available, ensuring suitability and better sizing of material based on the application.
McCloskey says the J4 delivers effective stockpiling, with wide main and side conveyors for enhanced material flow. The angle-adjustable 1200mm-wide ToughFlex main conveyor features a 3.912m-high stockpile and, with quick release and ground level access, the belt is designed to be easy to maintain and service.
ToughFlex is constructed with a special weave of two fabric plies and an additional binder warp (without the need for steel wire) resulting in reduced belt weight. The plies are reinforced to resist puncturing and are protected with heavy-duty, wear-resistant top and bottom covers.
McCloskey says that portability has not been compromised with the J4, despite its powerful capabilities. Mobility on-site and between sites continues to be a feature, with remote control tracks to move and position the crusher and maximise efficiency.
The company adds that technology has been a key factor in the development of the J4, with a DSE control panel for the highest operational performance and reliability providing push-button control of the jaw, track and feeder functions. The crusher is fitted with a telematics modem for the new 365SiteConnex programme, a connectivity solution for accurate monitoring of McCloskey products.
365SiteConnex is based on the latest communication technologies to collect, analyse and deliver information on the crushers, screeners and stackers.
“The J4 continues the momentum for our jaw-crushing product range, as we continue to develop new products that meet the evolving needs of our customers across industries,” said Toni Laaksonen, senior vice president, McCloskey International.
“As a company that is involved in the handling and processing of the Earth’s resources, we also have our sights set on sustainability. Our next commitment to an environmentally responsible strategy will be the introduction of our electric crushers, scheduled to be available in 2023.”
