Keestrack is launching a new B7H heavy-duty hydraulic jaw crusher, specially designed for the US market and the toughest of rock conditions in quarrying and mining applications.
The 70-tonne B7H hydraulic jaw crusher has a 30-tonne jaw and is adapted from Keestrack’s existing B7 electric jaw crusher which was launched in 2018. It has a vibrating feeder with 2-step grizzly of 2,200mm x 1,080mm (LxW) and a bottom deck in wire mesh of 1,450mm x 870mm (LxW) to optimise crushing results and to reduce wear.
The feed size of the material is up to 700mm, the feed opening is 1,200mm x 830mm and the outlet adjustment CSS is min.-max. 75mm–250mm.
The jaw crusher is equipped with the patented NSS, non-stop system, which protects the crusher from uncrushable feed and resets the CSS automatic during operations.
Keestrack sales director Frederik Hoogendoorn says the mobile crushing and screening equipment company is a pioneer in electric quarrying and mining machinery, having launched its first electric machine in 2006.
He adds that 90% of Keestrack machines are available in three versions: hydraulic, electric, and zero-emissions plug-in.
“A focus on sustainability is at the core of our company as this is the origin of our business,” Hoogendoorn said.
“Producing and recycling valuable raw materials is what mobile crushing and screening is all about, and our efforts are definitely having a positive impact on the ecological footprint.”
