Talking About Welding Equipment and Techniques

Hi there. I’m Nina. Welcome to my website about welding. The process of welding together metal takes a lot more than a hot iron and some metal wire. There are many different machines and practices people use to carefully and skillfully weld together metal. With the right techniques, you can create truly beautiful welds that hold up to the test of time. The strong metal welds are often stronger than the two metal pieces they join together. I would like to use this site to talk about the different types of welding equipment, techniques and safety gear used for this exciting industry. Thanks for visiting.

Why Crushing Needs Screening

by Matias Keranen

Crushers and screening plants help break down rocks and separate gravel from larger pieces. In quarries, these pieces of equipment help form those piles of differently-sized materials that will be packed up later and sold for construction, landscaping, and more. Sometimes there's not a lot of room for the equipment, and you may think you can get by with, say, just a crusher. Yet crushing needs screening, and not having a screening plant will only complicate the process of separating the materials.

The Additional Separation Step Makes the Process More Efficient

When you remove the smaller pieces of dirt and gravel that don't need to be crushed any further, you free up space in the crusher for the bigger rocks. You can fit more of the big rocks in there and go through the pile of material to be crushed a lot more efficiently. There's less power used and less time needed to turn those larger rocks into gravel. Overall, it's more efficient to have the screening plant first separate dirt dug out of a quarry.

Screening Can Be a Lot Faster Than Feeding Everything Through a Crusher

Related to efficiency is speed. Screening is often used to sift apart larger and smaller pieces after a bunch of rocks have been through the crusher. But if you're taking soil from a section of freshly dug dirt in a quarry, you may want to send all that through the screening plant first to separate all the smaller bits from the larger bits. If you feed everything into the crusher, that's going to take time as the gravel and rocks work their way through the whole crusher. There's no reason to place a lot of smaller dirt and sand particles in there if you can sift them out first. And a screening plant works fast. You are not adding a lot more time to the process if you use a screening plant before sending larger rocks through a crusher.

You're Just Not Going to Crush Everything to a Uniform Size

No matter how good a crusher you use, it's not going to crush everything to a uniform size. You're going to end up with rocks and gravel of varying sizes, albeit smaller than what you originally fed into the crusher, of course. You'll need to sort through the crushed rock to separate larger pieces from smaller pieces, and that's where screening plants come in. Just feed the newly crushed rock into the screening plant and let automatic sifting work its magic.

If you don't have a lot of room in which to place equipment, you can now find compact screening plants that have a much smaller footprint. Rather than choosing one piece of equipment and hoping you can get the rock sizes you need out of it, just look for compact crushers and screening plants that can fit in smaller spaces.
