Crushing and screening at an altitude of 4600 m

On a high plateau in Yushu (China), three Kleemann plants crush and screen rock and recycling material

The prevailing conditions in Yushu are already extreme for humans: In Yushu, Qinghai province (China), at an altitude of 4600 m, three Kleemann plants crush and classify limestone. The reliable, robust and modern Kleemann technology ensures that the two MOBIREX MR 110 Z EVO2 impact crushers and the MOBISCREEN MS 953 EVO screening plant do not run out of air – and hourly capacities of around 300 t/h are achieved.

Heavy-duty work on a high plateau: Two Kleemann MOBIREX MR 110 Z EVO2 impact crushers and one MOBISCREEN MS 953 EVO screening plant demonstrate strong performance even at an altitude of 4600 m.

Use of two MOBIREX impact crushers and one MOBISCREEN screening plant

When operating machines at high altitudes, it quickly becomes apparent how sophisticated and high-quality the technology is. Plants that want to excel even here must be uncompromisingly reliable and, above all, robust. Three Kleemann plants operate at high altitudes of 4600 m in Yushu in the Chinese province of Qinghai. Here, they must withstand extreme sub-zero temperatures and large temperature differences between day and night, and must cope with the low-oxygen air. In view of these conditions, the Kleemann plants are doing a great job: Two MOBIREX MR 110 Z EVO2 impact crushers and one MOBISCREEN MS 953 EVO screening plant crush and classify approx. 300 t/h aggregates for road construction.

MOBIREX MR 110 Z EVO2

The MOBIREX MR 110 Z EVO2 mobile impact crusher can be deployed universally and produces first-class final product quality. With a crusher inlet of 1100 mm and numerous technical highlights, a formidable production rate can be achieved with optimum cost effectiveness. Thanks to the compact design, the machine is easy to transport and can be assembled and disassembled again quickly.

Processing of natural stone and recycling material

The mobile MOBIREX MR 110 Z EVO2 crushing plants are used in Yushu in the processing of soft to medium-hard natural rock and in the recycling of construction materials. A two-stage crushing process produces a wide range of high-quality aggregates for asphalt and concrete mixes for road construction and building construction. In these fields of application, Kleemann plants have earned an excellent reputation in China.

The great efficiency of the technology, its efficient use of fuel, and its ease of operation thanks to the intuitive SPECTIVE operating concept are key advantages that the MR 110 Z EVO2 also demonstrates in Yushu. The MOBIREX mobile impact crusher can be deployed universally and, in doing so, produces first-class final product quality.

  • Optimised material flow as a result of extending system widths
  • Hydraulic gap setting
  • Simple and intuitive SPECTIVE control concept
  • Efficient and powerful diesel direct drive
  • High-performance post screening unit with oversize grain returning (option)

MOBISCREEN MS 953 EVO

The MOBISCREEN MS 953 EVO screening plant can classify up to 500 t/h of material and delivers a strong performance even under extreme conditions.

The MOBISCREEN screening plant classifies up to four grain sizes

A MOBISCREEN MS 953 EVO screening plant is responsible for precise end products on the high plateau in Yushu. It can discharge up to four graded aggregates. MOBISCREEN EVO screening plants from Kleemann are characterised by their flexibility of use, excellent transport properties, fast installation times, efficient operation and impressive performance values. The triple-deck screening plant can process up to 500 t/h of material. Operation is by means of a modern control system. This makes all functions easy to control, and operating statuses and machine functions can be viewed at any time.
