Double toggle jaw crushers are usually used for crushing hard, abrasive rocks, glass and ferrous metals. Unlike single ones, double toggle jaw crushers are much heavier and have a lot of moving parts. Plus they dont include rotary motion. Instead they crush materials between two massive jaw plates.
Jaw crusher has a large crushing force and fast running speed. Under the action of the huge impact and crushing stress, it withstands long term and periodic contact fatigue load and is prone to fatigue crack. Therefore, fatigue spalling is also one of the causes of wear. Corrosion wear
JAW CRUSHERS The Universal Overhead Eccentric Jaw Crushers are constructed from top quality material for rugged service in a tough industry! Universal Jaw Crushers are the most efficient on the market today. A deeper crushing chamber provides better nip angle while reducing rebound, ensuring continuous crushing action with less abrasive wear.
3 A double toggle jaw crusher crushes stone only by two jaw plates, which mean that the feeding material would be reduced when the two jaws compressed with each other. 4 Eccentric is behind the swinging jaws, which can protect the eccentric form damages. Single toggle Jaw Crushers
A double toggle jaw crusher is much larger, heavier, more moving parts and lower throughput than modern single toggle jaw crushers. The lower throughput statement is a bit misleading because its partially attributed to the type of bearings they have versus modern crushers, so if one was to upgrade the bearings, throughput could be closer to that of a modern jaw. Anyway, double toggle jaw ...
A jaw crushers flywheel, toggle plates, pitman, eccentric shaft, and driving motor generate the crushing action and provide the energy needed to break the material. There are some different styles of Jaw Crushers, the most common being the overhead eccentric jaw or a double toggle jaw.
