A comparison of jaw crushers with the same capacity reveals that double-toggle jaw crushers are more expensive than ordinary jaw crushers. For this reason, mostly single-toggle jaw crushers are used in the aggregate sector, while double-toggle jaw crushers are used mostly for crushing very hard and highly abrasive materials.

Jaw-crusher Construction. Jaw crushers are heavy-duty machines and hence must be robustly constructed. The main frame is often made from cast iron or steel, connected with tie-bolts. It is commonly made in sections so that it can be transported underground for installation. Modern jaw crushers may have a main frame of welded mild steel plate.
The Eskay Creek deposit is an unusual high-grade precious and base metal volcanogenic massive sulphide and sulphosalt deposit hosted in volcanic and sedimentary rocks of the Lower to Middle Jurassic Hazelton Group. This deposit consists of several zones distinguished by differing ore mineralogies and grades. Published geological reserves for the deposit are 4.3 million tonnes grading 28.8 ...

Name is about as close as one can get to a "novel" that was written by a machine and for a machine: it seems especially primed to attract and repel spam-blockers with its pseudo-porn opening, and yet it also tosses a distracting bone to the bots with its stream of seemingly random verbiage after its first paragraphs. But far as we can tell, Name is the exorbitant creation of a single human ...
