simply for strength and more rigidity of the frames. ■

Izharis!!



That is what bhaskar is also asking.

How is a rectangle stronger than a circle pipe, both sharing the same thickness and the same perimeter/circumference.

This happens to be a fundamental question.

Suppose we go in for circle pipe instead of a rectangle then what has to be done to get the same rigidity as rectangle pipes.

There is no difference. you can use both. Many companies using square profiles because fabrication is more easy.

We, as consultaces has developed other systems than frame structures. In case of vibrations, keep care of weldings.

There is a really good book "Hollow Profiles" for design and calculations. ■

Greetings Sandeep,

there is more weld area using a square tube, but one must be very carefull not to over heat the side plates while welding-especially in repair of an old side plate. When you set up your welding job be sure to tack weld the tube on the flats in several places dependiing on the size of the tube to prevent twisting of the tube while welding.

This is one of the many reasons I prefer the Bradford Breaker from Pennsylvanis crusher as it is simple to repair, maintain and the design has be in use for almost a century.

The simpler the better, the less complicated the better, the fewer parts the better, and the less maintenance the better. That is why I am interested in capsule pipelines so much.






Square tubing allows one to weld gussets in center of the flat and their is no reason you cannot weld three gussets on each flat side of the square tubing to increase the strength of the screen, but this does not eliminate inspecting the screen sideplates for cracks around the shaker arm hole etc. or making sure the rubbers are free of packed material if you use isolation rubbers in the shaker arms. Happy welding.■

The vibrating screen manufacturers that I have worked for since 1977 use BOTH. BOTH are quite acceptable.

1. Typically reduction of overall mfg cost is the reason change is done. Reduce mfg cost> increase profit margin.

2. Round pipe sheds material better, less static load being carried

3. Must be careful on welding techniques on round to ensure any rails welded are NOT TOO STIFF or RIGID to avoid cracking off

4. Round pipes are typically SCHED 40 mtl, must be careful at ends to ensure no WARPING or TWISTING....squareness, typically using a welding JIG to ensure SQUARENESS is kinda mandatory in vibrating screen manufacture. ■
