ATM INDUSTRY AJM series modular jaw crusher adopted and improved the original design, technology and fabricating process of international famous crusher brand, all components perfectly interchangeable. AJM is used in a wide range of applications, both stationary and mobile, quarry, mining, building materials, recycling, power station, metallurgy. Powerful moving jaw and a longer stroke from the steep toggle angle ensure high efficiency and capacity; Modular structure design does not only eliminate welding stress concentration that traditional welded frames always have effectively, but is also easier to transport, install, operate and maintenance; Hydraulic adjustment setting wedge is easier and more effective than traditional adjustment shim, where the crusher setting can be manually adjusted with tools that are supplied with the crusher in a matter of minutes without having to handle dirty and bulky shims; Integral motor bolted with main frame reduces installation space and shorter V-belts shall apply than that of separate motor base, additionally, flywheel protection cover could be used optionally; Optimal nip angle between moving and fixed jaw provides more crushing power, and minimizes abrasion of jaw plates greatly; Robust and reliable structure results from premium material and fabricating process, that casting steel is adopted for the pitman, flywheels and frame bearing housings, which also bears unnecessary loads.
