Crushing and Sizing Components
Crushing and sizing components must be hardfaced with high performance materials and overlays to do their job reliably and with long service life. But the access to these materials can be challenging. Oerlikon Metco's innovative weld hardfacing alloys for crushing components are breaking new ground in the mining industry.

repeatedly lifted and dropped that crushes and breaks the formation. Figure shows the basic elements of a cable tool rig (Anderson Lund, 1979). With a cable tool rig, an experienced driller can drill through any formation, including large crevices and caverns that can cause problems with other drilling methods.

Design and Calculation of a Concrete Mixer (100 kg)
mixer uses a revolving drum to mix the components. The compressive strength of concrete depends on the aggregate grading, aggregate/cement ratio as well as the water/cement ratio. The freshly mixed concrete should be workable to be properly placed and the hardened concrete needs to be durable and attain a specific compressive strength.

Crushers
Both cone and gyratory crushers, as shown in Figure, have an oscillating shaft. The material is crushed in a crushing cavity, between an external fixed element (bowl liner) and an internal moving element (mantle) mounted on the oscillating shaft assembly.
Concrete Slab Surface Defects: Causes, Prevention, Repair
3. Warm the subgrade before placing concrete on it during cold weather. 4. Avoid placing a slab directly on polyethylene film or other vapor barriers. Use a 100mm (4in.) layer of compactible, drainable fill (not sand). A "crusher run" material, usually graded from 38 mm to 50 mm (11/2 in. to 2 in.) down to rock dust, is suitable.
