McCloskey crusher inspired by customer feedback
12 October 2017
McCloskey International has introduced a new version of its I44R mobile impact crusher.
The I44Rv3 combines the productivity of a 1,117 mm (44 in) impactor with the versatility of a full screening and recirculating system, allowing operators to produce a crushed and screened final product with one machine.
Following worldwide field site visits, feedback from the customers has resulted in significant other changes, including direct drive, an enhanced material flow path, larger pre-screen, and a more open chassis.
The I44Rv3’s radial return conveyor features full length dust suppression control, allowing operators to recirculate oversize material from the screenbox back to the feed hopper or radial a complete 90° while running.
Other new features include a more open chassis for ease-of-access, a larger double deck prescreen for more efficient fines removal, and a direct drive crusher, delivering more power, along with lower fuel costs.
McCloskey says efficiency is boosted with the new design, particularly in the material flow path. Each sectional component is wider than the last to allow an unrestricted flow without funneling or narrowing, eliminating material bridging. The straight sided chutes manage the material as it passes through each section that is wider than the last – feeder, to prescreen, and chamber to a wider optional underpan.
The I44Rv3’s larger double deck prescreen brings more efficient fines removal to production, maximizes the crusher’s productivity, and delivers screened product via a straight chute to the 650mm side conveyor. In addition, the main conveyor is now wider at 1,200 mm (48 in) to accommodate a larger amount of prescreen material, and to allow for better discharge from the crushing chamber.
“Getting feedback from our customers allows us to continually improve our products based on their production and business needs,” said president and CEO Paschal McCloskey.
“The redesign of the impact crusher line has resulted from a collaboration between McCloskey and our customers.”
