McCloskey International will unveil the new J4 as the latest entry into McCloskey’s jaw crusher line. Launching into the European market at bauma 22, October 24-30, the J4 builds on the robust features of the existing product range, with an exciting line-up of features aimed at boosting productivity and offering enhanced durability across applications.
Designed to withstand the toughest conditions worldwide, the J4 delivers high production due to its innovative jaw chamber design and enhanced material flow. The large 1060mm x 700mm (42” x 28”) jaw opening accommodates large feed sizes, contributing to higher production in material processing.
The material path is enhanced with the 1064mm x 4247mm (41.9” x 167.2”) 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.
The J4 delivers industry-leading stockpiling, with wide main and side conveyors for enhanced material flow. The angle adjustable 1200mm (48”) wide ToughFlex main conveyor boasts a 3.912m (12’ x 10”) high stockpile, and with quick release and ground level access, the belt is easy to maintain and service. ToughFlex is constructed with a special weave of 2 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. At the end of it’s lifespan, ToughFlex belts can be easily recycled unlike belts reinforced with a metal ply.
While a side conveyor remains an option for many jaw crushers in its class, the J4’s integral folding conveyor is standard and has an 650mm (26”) adjustable sped belt fueling a stockpile height of 3.44m (11’ x 3.6”).
McCloskey engineers have designed the J4 to meet the evolving requirements of today’s projects and operations. Despite the position of the J4 as a powerhouse, portability has not been compromised. Mobility on-site and between sites continues to be a feature with remote control tracks to easily move and position the crusher and maximize the efficiency of any project site. Also contributing to efficiency, particularly in remote locations, is the high volume fuel tank, sufficient to run the J4 for approximately (20?) hours.
Technology has been a key factor in the development of the J4, with a 12” 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 program, a complete connectivity solution for highly accurate monitoring of McCloskey products. 365SiteConnex is based on the latest leading-edge communication technologies to collect, analyze and deliver information on the crushers, screeners and stackers customers rely on to produce the highest quality products with the least amount of downtime.
As with all McCloskey equipment, safety is paramount, and the J4 is equipped with a number of features to ensure the workplace and the operator are secure. Engine safety shutdown systems, start-up alarms, full safety guarding, external maintenance access and a tagout capability on the isolator all contribute to the safe operation and maintenance of the equipment. Ground level access also promotes safety, and allows for quick service and maintenance, reducing the downtime for the operation.
“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. We have always designed our equipment to ensure it contributes to the productivity and business success of these operations. 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. ”
said Toni Laaksonen, Senior Vice President, McCloskey International.
The J4 jaw crusher will be formally introduced bauma 2022, October 24-30, 2022 in Munch, Germany. The crushers are suited particularly to aggregates, construction and demolition recycling, and site preparation.
