Keestrack B4 Crushing Granite
The Keestrack B4 breaking down granite rock through 2 vibrating pre-screens and a patented non-stop system for continuous production.
For primary crushing, landfill recycling, and concrete recycling, the Keestrack B4 (previously known as Apollo) Mobile Jaw Crusher includes a patented non-stop system ensuring continuous processing while protecting the machines when working through uncrushable materials. This powerhouse is suitable for a wide array of applications including most medium and hard stones, quarrying and mining, construction and demolition waste, and many more including coal, gravel and slag.
The B4 is designed with an independent double deck vibrating prescreen and automatic feeding system. This system ensures an optimal supply within the crushing chamber by detecting an overload and slowing down the feed for best results and prevention of jamming. Load sensing hydraulics reduce fuel usage by 25% and if environmental responsibility is important for your business, the B4 is also available in a a full-hybrid e-version.
The hybrid model includes a 242 kW diesel engine and a 225kVA on-board generator. During plug-in operation the diesel engine doesn’t have to be started, and complete energy management is controlled automatically, including the electric supply of a secondary unit such as a screener or stacker. This results in greatly reduced fuel consumption and maintenance.
