Jun 26, 2017 Immense excavator machines rip up the lignite; these can be seen at the west end of the face in the high-resolution download of the image. At this mine, the machines scrape off the overlying non-fuel rock layer (known as overburden), dig up the lignite, and then replace the mined strip with the overburden material as the rockface advances.
Jul 30, 2018 Germany has been the largest lignite producer in the world since the beginning of industrial lignite mining. It still is, followed by China, Russia, and the United States. The softer and moister lignite (also called brown or soft coal) has a lower calorific value than hard coal and can only be mined in opencast operations. When burned, it is more CO2 intensive than hard coal.
Jun 29, 2021 The mining company RWE is already being paid more than $3 billion by Germany's government to phase out its coal mines. GUIDO STEFFEN: And if politics say we paint the town red, then everybody will

Discover Bagger 258: The "Blue Wonder" in Schipkau, Germany: The industrial monstrosity known as Bagger 258 is a colossal mining machine built in the DDR but now left for dead in a German field.
Bagger 288 (Excavator 288), built by the German company Krupp for the energy and mining firm Rheinbraun, is a bucket-wheel excavator or mobile strip mining machine. When its construction was completed in 1978, Bagger 288 superseded Big Muskieas the heaviest land vehicle in the world, at 13,500 tons. It took five years to design and manufacture, and five years to assemble with total cost reaching $100 million. In 19

The three types of crushers most commonly used for crushing CDW materials are the jaw crusher, the impact crusher and the gyratory crusher (Figure 4.4).A jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle (Figure 4.4(a)) and it is the most widely used in primary crushing stages (Behera et al., 2014).
Impact crusher is a kind of crushing machine which uses impact energy to break materials. It is suitable for handling brittle materials of medium hardness with side length not exceeding 500mm and compressive strength not exceeding 350 mpa. The impact machine has the characteristic of large crushing ratio, low energy consumption, high efficiency
The impact crusher is a new and high-efficient cement crusher, with advantages of small size, simple structure, and large reduction ratio, less energy consumption, uniform practical size and flexible selectivity.The remarkable features of impact crusher is large feeding mouth, impact crusher own 1.5 times or even 2 times larger crushing cavity than that of other crushers.
