General 640 — Mobile Crushing & Screening Plant (Jaw + Impact)

The General 640 is a tow-behind, closed-circuit wheeled crushing and screening plant that pairs a GPJ 60 jaw with a GNR 50 impactor at 40-70 tph. It takes 500 mm feed, travels on one truck and is up and running within minutes on its hydraulic legs. As the smallest and most affordable model in the range, it is tuned for a steady, reliable rate on hard, abrasive rock. Main Equipment The General 640 is the compact entry point of the range: a tow-behind, closed-circuit wheeled crushing and screening plant that pairs a jaw with an impactor at 40-70 tph. It swallows 500 mm feed on a single truckload of equipment and keeps a calm, dependable pace on the hardest abrasive stone — the smallest, most affordable member of the family. Working principle Technical data Screen meshes and the final gradation are tailored to each job and the stone being fed. Where it is used Small and mid-size quarries, roadworks and general construction are its home ground, and it copes well with tough, grinding minerals. Running at a modest rate, it is kind to wear parts. Everything folds onto hydraulic legs, so the unit can be lifted from one job and dropped onto the next without fuss. 640 vs 800 The 640 is the economical entry model; when capacity needs grow, the 800 is the next step up.

The 640 slots straight into such a line together with extra crushers and screens, so you deal with a single team that owns the result and keeps every spare part in step.
