Manitex Jib Crane 50155s
One of the newest companies that are taking over the crane market is a company named Manitex. A company that originates in 1993 and went public in 2006. Manitex produces heavy machinery handlers with a great quality, thus, gaining a lot of good reputation the last few years. Recently, they presented their jib crane - the Manitex 50155S, that features 50 tonne platform, a 47 meters - 5 section boom etc.

Roll Crusher Explained
Roll crusher is a specific type of
heavy-duty equipment and is widely used in industrial and mining
processes. A common roller crusher consists a couple of big
cylinders, positioned on a horizontal axis. Between these two
cylinders, the raw materials are being crushed in small pieces. So,
the roll crusher is suitable to a broad range of applications and
most suitable to coal mining, concrete recycling and mineral
production applications.
A typical roll crusher is consisted of two cylinders, both featuring a ceramic or steel finish. Above the two rollers, there is a hopper that drops the materials down through the gap between the cylinders. To crush the materials, the rolling cylinders rotate in opposite directions and so smash the materials between as they fall downwards. The friction between the cylinders efficiently crushes any material, then falls down into a so-called collection bin. But prior any use, the contractors must adjust the space between the rolling cylinders in order to get the desired size of the crushed particles.
The roll crusher surface is usually smooth, but some models feature a textured surface. That depends on the application; for crushing more delicate materials (metals, minerals, etc.), smooth roll crusher surface is most suitable, while for crushing rocks and similar heavy materials, textured surface is recommended. Some applications can not be efficiently carried out with a double roll crusher. However, there is a way to carry out such application using a roll crusher with four cylinders. A four-cylinder roll crusher takes a material to pass through the first two cylinders first, and then into the second pair of cylinders, mounted just below the first pair. The second pair of cylinders is used for crushing the materials once again, in order to achieve a better and finer product.
Four-cylinder roll crushers have a very simple and compact design, which contributes to very small maintenance costs. Also, they effectively produce materials of same size, in order to make the rest of the production process easier. The roll crusher might be the most cost-efficient unit for processing small loads of materials, but it surely is not a good choice for large production capacity. The roll crusher surface is not made from heavy-duty materials, which means it can easily get damaged by some abrasive or rough material, leading to expensive repair or part replacement.
So, when considering a roll crusher, the prospective operators must think about the total production capacity of the unit they expect. Also, they need to consider the size, the abrasiveness and the roughness of the materials they will process with the roll crusher.
