Surface miner  It is a Continuous surface mining machine which is used in coal mines, lime stone mines and also in sand stone this machine is made by wirgton, takaraf, and vovest alpine company.  Applicability  1. It is applicable where the strength of materials is from 12 to 50 Mpa 2. It can be operate 2.5 cm thin coal seam or other bedded deposits and climbing inclination not greater than 15". 3. It can be used in flat surface not hilly terrains. 4. This machine is very effective developed areas where drilling and blasting is prohibited.  Advantages  1. Selective mining is possible.. 2. Better exploitation due to lower mining cost. 3. Lower processing cost because the coal doesn't need pass through the beneficiary small plant.  Production  Q = Vm x h x b x 60 m ^ 3/h Q = Quantity cut, (m ^ 3) / h Vm= Machine speed, m/min. h = Milling depth, m b = Milling drum width, m

The dramatic output in the volume of the bulk material during the past few decades has generated an increase need of Heavy Earth Moving Machinery (HEMM) in the field like mining project, Irrigation project ports, big cities etc throughout the world. Heavy Earth Moving Machinery (HEMM) comprise of machines which cut and extract earth, blast rocks, sand and other loose materials and then transfer them to a predetermined position and finally dischange the material on dumping points through dumpers, belt conveyors, etc. Heavy Earth Moving Machinery (HEMM) are the combinations of various mechanisms designed to perform the special type of work as mentioned above. The mechanisms are ▪️A prime mover (diesel engines or electrical motors). ▪️A power transmission system including clutches, gear boxes, chain sprockets, etc. ▪️Control systems, and ▪️Mechanical linkages BUCKET WHEEL EXCAVATOR   Introduction    Bucket wheel excavator is a multi bucket continuous excavator.
