Mining screens

Screens are widely used in the mining, aggregates and recycling industry for classification of bulk materials. The common medium screened are mineral ores, natural stone, coal, sand, salt or waste. The medium is separated to different sizes in line with the equipment downstream.

thyssenkrupp Mining Technologies offers screens based on decades of expertise and cutting-edge technology – tailored to client demands and sustainable operations.

What are screens and how do the work?

Screens consist of a screen media, which separates fine from coarse particles as well as a drive system generating the necessary vibration or rotation in order to move, loosen and transport the screening material on the screen deck.

Screens are typically in operation in these industries:

  • Mining
  • Mineral processing / Aggregates
  • Recycling
  • Chemical / Pharmaceutical / Food
  • Metal / Plastics

Screening plays a key role in mining and mineral processing industry, where screening equipment is used in crushing and grinding circuits, for classification as well as for dewatering and de-pulping. The wide range of different screens from thyssenkrupp Mining Technologies is perfectly suited for these industries an offers the right screen type for every application.

Categories of screening equipment

Screens can be differentiated according to their working principle. They include vibrating screens, roller screens (wobblers) and rotary screens with each screen type being designated for certain purposes and applications. Roller screens are used for classification of sticky and fibrous material, e.g. in the coal or natural stone industry. Rotary screens are used for coarse screening in quarries, including materials that are difficult to screen. They also operate in waste and compost treatment plants.

However, with a broad range of applications and the ability of adaption to different feed materials and screening jobs, vibrating screens are the most widely used screen type.

thyssenkrupp vibrating screens portfolio

The main applications of thyssenkrupp vibrating screens are in the mining and mineral processing industry. From pre-scalping of ROM material up to fine screening in the gravel and sand production, in both dry and wet processes, vibrating screens can be found in numerous places in processing plants as well as in silo and dozing systems. Especially in crushing and grinding circuits, vibrating screens play a key role for the production of qualified products.

The wide range of different screens from thyssenkrupp Mining Technologies is perfectly suited for these industries. We offer the right screen type for every application.

Screens from thyssenkrupp Mining Technologies are based on a combination of state-of-the-art technology and decades of experience. They are particularly distinguished by their high screening efficiency and ease of maintenance. This makes them a sustainable solution for your operations.

Our screening equipment generates real added value by optimized weights and overall heights along with significant operational flexibility as well as product quality and performance.

Our experts, with their extensive knowledge and experience gained from a large number of installed screens around the globe, are at your disposal for advice and support.

thyssenkrupp Mining Technologies screens

We offer you the best and most innovative vibrating screens in the market.

Linear motion screens

thyssenkrupp linear motion screens are often called Banana screens due to the design with different inclinations of the screen decks and use the principle of thin layer screening.

They achieve high throughputs and high separation efficiency. They are built as single and double deck version and, of course, also with continuous straight screen decks as well as grizzly pre-scalpers. These are used in primary screening of coarse feed material at the highest loads.

Our linear screens meet versatile requirements, e.g. for dry and wet screening as well as dewatering of bulk materials. Such materials are hard rock, limestone, gravel, coal, mineral ore, phosphate, sand and salt. The infinitely variable stroke of the unbalance exciters and a vibration isolation frame are just two of the many features thyssenkrupp offers.

Grizzly screens

Grizzly screens are designed and reinforced to withstand the heavy duties typically present in primary applications. They can process run of mine material with up to 2m edge length with minimum downtime and thereby guarantee continuous operation.

We offer various types of grizzly screens, which can be equipped with grizzly bars or grizzly fingers for sticky and difficult-to-screen feed materials. Our grizzly bars are made of highly wear resistant steel and offer maximum lifetime of the screen decks.

Circular motion screens

Our circular vibrating screens are simple, robust designs characterized by high reliability and screening efficiency. For this reason, they have been successfully used worldwide for many years in the screening of gravel, crushed rock, ore, coal and in the recycling industry. The latest developments offer significant advantages in terms of acquisition, installation and operation. This is thanks to a large number of innovative detailed solutions.

Our circular vibrating screens are available with screen areas from 4 m² to 17 m². Also with up to three screen decks and with different screen linings. This can therefore be adapted to a wide range of requirements.
