Building a Double Toggle Jaw Crusher (12 replies and 3 comments)
There you go,
I also updated the calculations a bit.
Hi,
Just a quick question what is the min max size piece you expect it to produce? From what I can tell it looks like almost 6" product is this correct? Also what is the throw of the eccentric? I think if you know what size product you want to make will predict the rest of the machine. Will also need to know the hardness of the material you plan on crushing. But then again this is a large crusher and I would think most soft rock as a majority of the rock.
For everyone's benefit, here are the images for this crusher fabrication project.

This may be useful: Due to their simple design and easy maintainability jaw crushers are widely used as primary size reduction equipments in mechanical and mining industries. As jaw crushers break minerals & ores of high strength and the economy of many industries depends on its performance; it is essential to improve the efficiency of the present design. The kinematic analysis of single toggle jaw crusher shows that the forces on the moving jaw plate at different crank angle are different and hence power generated varies with crank angle. One way to increase the efficiency is to store the energy in a flywheel when the supply is more than the rate of consumption and to utilize the same when the supply falls down. Hence efforts are made to design a flywheel to minimize the wastage of power and to improvise the performance parameters of single toggle jaw crusher.
Jaw plate wear has considerable affect on the life of jaw Crusher which is caused by the slipping motion between the fed material and the jaws. This wear is predominantly serious in the fixed plate and hence the liners of the fixed jaw should be properly chosen. In addition to this the toggle bar which acts as a safety lever has to be precisely designed. The design aspects of flywheel, spring of tension bar and toggle bar are discussed in this paper.

hello there.
I am civil engineer currently working on crushing quarry. I am getting a problem about my double toggle jaw crusher. the flywheel, toggles and everything is currently working well, but the problem is that its not crushing properly. in addition there are rubber or fiber parts at the front and rear of each toggle plate, so it destroyed those rubbers at the first time we started the machine to function.
so what is the problem, which type of troubleshooting should i have to start with, which places should i have to focus.
Hello there,
I need help with the Calculation of relevant bearing loads at the drive kinematics of a double toggle jaw crusher.
I'm a mechanical engineering student from germany and have to construct a double toggle jaw crusher for my construction project of my third semester.
I have to determine all relevant reaction forces in the bearings at the drive kinematics and I have an idea, but I'm clearly not sure if I'm doing it correctly.
In the attachment I'll give all relevant technical information. (I hope it is readable, Otherwise I'll give my calculations in digital format.)
Translation of all relevant given Dimensions:
PS: English is not my first language, so I apologize for any spelling or grammar mistakes. Thanks for helping my Build this Jaw Crusher.
