Kleemann technology performs impressively at an altitude of 3000 m

Shangri-La (Yunnan province), China: In Shangri-La in Yunnan province, a Kleemann MOBIREX MR 130 Z EVO2 impact crusher crushes limestone and, in conjunction with a Kleemann MOBISCREEN MS 953 EVO classifying screening plant, produces four different, high-quality end products. Despite being used at altitudes higher than 3000 m above sea level, the Kleemann plants work reliably and efficiently.

Extracting aggregates for road and path construction

Even just the construction of roads at high altitudes represents a challenge. However, extracting the raw materials required to produce asphalt and concrete is particularly challenging. This is also true in Shangri-La in Yunnan province. At an altitude higher than 3000 m above sea level, a road construction company in the region successfully tackles this problem by using Kleemann's mobile crushing and screening plants.

A MOBIREX MR 130 Z EVO2 mobile impact crusher and a MOBISCREEN MS 953 EVO mobile screening plant crush and classify limestone precisely in four specified aggregate fractions. Both plants also perform impressively at high altitudes. The Kleemann plants guarantee fast production progress. Crucial factors in this are not only a constant crushing process but also high machine availability.

MOBIREX EVO2 impact crushers can run for 16 hours a day

The first MOBIREX EVO2 impact crusher, which a customer of the Wirtgen Group in China acquired some time ago, has already completed over 9000 operating hours and demonstrated a strong performance and a high level of reliability.

The second mobile impact crusher plant, likewise a MOBIREX MR 130 Z EVO2, is also subject to heavy demands. For between 15 and 16 hours a day on average, the quarrying team uses the plant to produce aggregates for road construction. With cost-effective operation, the machine offers an important Kleemann advantage – it makes efficient use of fuel. The powerful diesel direct drive ensures minimal consumption per ton of end product.

Using interlinked operation means that the MOBIREX EVO2 impact crusher communicates with the MOBISCREEN EVO screening plant. In doing so, the impact crusher adapts its speed in order to optimally supply the screening plant with material. This ensures the best possible material flow and therefore reduced wear, low fuel consumption and, ultimately, low production costs.

Easy transportation

In addition to its efficiency and high performance, users in Yunnan province also appreciate other benefits, especially the machine's versatility, robustness and ease of transportation. For example, the MOBIREX EVO2 impact crusher's post screening unit is easy to remove and can be transported separately. This enables a transport width in compact container dimensions of under 3 m. This means that conventional low-loaders can transport the MR 130 Z EVO2 and the MOBISCREEN MS 953 EVO mobile screening plant from one site to another.

Environmentally-friendly operation

Kleemann has also ensured that plant operation is as quiet and produces as little dust as possible. The ergonomic power pack enclosure, which is available as an option, effectively insulates noise sources from the crusher. A water spray system largely traps the generated dust at various material transfer points in the plant, such as on the crusher inlet, the crusher discharge conveyor, the side discharge conveyor and the post screening unit. As a result, the MOBIREX MR 130 Z EVO2 lays the basis for environmentally-friendly production. In many markets, these provisions also enable the plant to be used in urban areas.
