Estimate the hourly production in LCY of a 3 CY articulated wheel loader excavating hard materials from a pit and moving it to a stockpile. The average haul distance is 350 ft and the grade is 10%. The bucket fill factor is 1 and the efficiency is 45 min/hr. Find hourly production in LCY/HR. Please help me with right solution... Urgenttttttttt... Thank you
What is the difference between a roughage and a concentrate? Give an example for each category.
The crushed stone output from a 36-by 42-in. crusher, with a closed opening of 2 ½ in (output is 50 tph)., is passed over a single horizontal vibrating screen with 1 ½ in. openings. If the permissible screen efficiency is 90%, use the information from Peurifoy to determine the minimum-size screen, expressed in square feet, required to handle the output of the crusher. please show complete solution use 4 decimal places
A belt conveyor is required to deliver crushed limestone having a bulk density of 75 lb/cu ft at the rate of 200 tons/hr. The conveyor is to be 200 ft between center of pulleys with a rise of 25 ft. The largest lumps are 4 in. and constitute 15% of the total. The conveyor will discharge over the end. For a belt speed of 200 fpm, what is the minimum width of belt that can be used? Calculate the horsepower for the drive motor.
A contractor needs 403 m3 of aggregate material for a highway construction project. The required dryunit weight of the compacted fill is 20.82 kN/m3. The aggregate material is available at a local supplyyard and is sold by measuring in tons and not by volume. The moisture content of the stock is 7%. Thecost of the aggregate material per ton is 60.B.1.1 Determine the amount of water present in the aggregate stock of the local supplyyard.B.1.2 Determine the amount of aggregate material the contractor should purchase in tonsto have exactly the correct volume of compacted material.B.1.3 Estimate the total cost the contractor has to bear for the purchase of the material.
A customer estimates that he is getting 30 cubic yards(loose) of gypsum in his scraper. Determine the percentoverload if the load estimate is correct. The maximum loadcapacity of the scraper is 84,000 pounds.
A bottom dump hydraulic shovel with a 5 cubic yard heaped capacity bucket is excavating in hard clay. The depth of the excavation is 12 feet. The shovel has a maximum rated digging depth of 34 feet. The haul units can be positioned so that the swing angle is 60 degrees. The job efficiency is 50 minutes per hour. Find the expected production per hour.
