Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

A pitman of a jaw crusher comprising an upper part, which comprises an upper supporting point for supporting the pitman in the body of the jaw crusher, and a lower part comprising a lower supporting point for supporting the pitman in the body of the jaw crusher through a toggle plate. The lower part of the pitman comprises sidewalls and …
Description. The pitman is the main moving part in a jaw crusher, which forms the moving side of the jaw.. A jaw crusher pitman has two supporting points for supporting it in the body of the jaw crusher, the upper supporting parts of the pitman consists of flywheel and eccentric shaft.And the lower supporting parts consists of toggle …
These non-choking jaw plates have been developed in two styles, reversible and non-reversible. The advantage of the reversible design has been outlined in connection with its application to the gyratory reduction crusher. For both types of jaw plate, the effective receiving opening is reduced, as compared to the standard, straight-plate setup.
® C130™ jaw crusher is the latest addition to the successful ® C Series jaw crushers range. The small nip angle and excellent kinematics ensure aggressive crushing along the whole length of the …
1.2.3 Hammer crushers 1.2.3.1 Principle of operation Single-shaft and double-shaft hammer crushers have been used for many decades to crush a variety of materials As primary and secondary crushers, they are used for crushing bulk materials, e. g. limestone, marl, coal, gypsum, clay, etc. Huge hammer crushers in quarries can reduce material with ...
Average throughput rate of single-toggle jaw crusher, standard version, tolerance ± 10% Double-toggle jaw crushers Design Double-toggle jaw crushers are equipped with a double-toggle system, which is con - trolled by a pitman that moves up and down under the influence of an eccentric shaft, causing the toggle plates to alternately flex and ...
Jaw crushers are mainly used as primary crushers to produce material that can be transported by belt conveyors to the next crushing stages. The crushing process takes place between a fixed jaw and a moving jaw. The moving jaw dies are mounted on a pitman that has a reciprocating motion. The jaw dies must be replaced regularly due to wear.
Crushing occurs when the pitman moves toward the stationary jaw. There are two main types of jaw crushers – single toggle and double toggle. The single toggle jaw crusher features a pitman …
Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.
improper definition of the problem will cause the engineer to waste time or arrive at an incorrect solution. It is important that the stated needs be real needs. A great design may be worthless if it duplicates other known designs or doesn't benefit many people. Broadly define the needs and distinguish them from possible solutions. An example ...
The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It …
I really appreciate these responses. So my main interest in the high pinion front isn't the added strength; who doesn't like the dea of added strength but I hope that I'm not testing it that hard. But, I do like the SOA and I don't like the dropped pitman or lowered transfer case. You indicated "may" cause a clearance problem.
In a typical jaw crusher, two outer bearings located on either side of the main frame support an eccentric shaft, while two inner bearings support a movable jaw. These are commonly known as "Pitman" bearings. The reciprocating motion of the shaft moves the Pitman against a second, stationary jaw.
Indeed, installing a dropped Pitman arm by itself will cause bumpsteer which it sounds like you're experiencing. 2) That your toe-in is set between 1/16" and 1/8". Also if you have an automatic locker in the rear, that will make it want to move left/right a bit as you get on/get off the gas.
