· So if a die has 1000 inches of cutting rule and is rubbered in strips of ½" wide on each side of the knife, it will calculate to 1000 x 300 and 1000 x 50 or 350,000 lbs of pressure or 175 tons. We use a factor of 400 pounds per linear inch of rule up to 500 pound per inch depending upon material being cut. Paper is 400 pounds.
Double-articulation cranes, which can load at a rate of 1,000 tons per hour, represent a widely used method, and the use of shore-based gantry cranes, reaching 2,000 tons per hour, is growing. A crane''s discharge rate is limited by the bucket''s capacity (from 6 to 40 tons) and by the speed at which the crane can take a load, deposit it at the ...
· Using the values for inside diameter of the raceway and the outside diameter of the individual conductor from the example, you get the following value: 1.05 x (D ÷ d) 1.05 x (5.07 in. ÷ 1.60 in.) = 3.33. Because this calculation results in a number greater than 3.0, you probably won''t have a jamming problem. Conductors need headroom, too
Where belt drive fan speed can be altered by adjusting the motor pulley, direct drive fans (since they have no pulleys) must use a different method. To adjust a direct drive fan''s speed (also motor speed) or to provide a means of meeting an exact performance requirements, a speed control can be
This is the correct speed at which the 14″ conveyor with cut and folded, and short pitch flights will convey the actual capacity of 323 cu. ft. per hour. Graphic selection of this conveyor could also be accomplished by use of the 30% A nomograph on page 22 and the selection capacity of 1817 cu. ft. per hour.
The historical method that CEMA provides to calculate T2 slip is as follows: T2 slip = Te x Cw, where Cw is the CEMA wrap factor for a rubber surfaced belt. The wrap factor can be as small as 0.08 for dual drive systems with rubber-lagged drive pulleys, an automatic take-up, and 420° of wrap angle, or as large as 1.2 for a single drive system ...
efficient replacement, you need to determine operating hours, efficiency improvement values, and load. Part-load is a term used to describe the actual load served by the motor as compared to the rated full-load capability of the motor. Motor part-loads may be estimated through using input power, amperage, or speed measurements.
Recovered papers can use considerably less energy in pulping than wood-based pulp, so making secondary fibers competitive with ones can save significant energy. A 20-ton per day FRT pulper now operating commercially annually saves about 7,000 tons of waste fiber from being land filled, and requires 11 to 30 kWh per ton for pulping. By
4. Select a suitable conveyor belt speed. 5. Convert the desired tonnage per hour (tph) to be conveyed to the equivalent in cubic feet per hour (ft3/hr). (ex. 1000 tph x 2000 / 60 = 33333 ft3/hr) 6. Convert the desired capacity in cubic feet per hour to the equivalent capacity at a belt speed of 100 fpm.
the work piece. The cut produced by plasma jet is very clean and its quality can be improved by using a water injection arc plasma torch. Plasma cutting can be used on thicknesses upto about 150 mm but the process is very slow. 2.2.4 Cold Sawing When a section cannot be cut to length by cropping or shearing, then it is normally sawn.
The calculation of density is quite straightforward. However, it is important to pay special attention to the units used for density calculations. There are many different ways to express density, and not using or converting into the proper units will result in an incorrect value.

· A faster belt speed—4.5 m/sec—is used to reduce the belt width from 1,600 mm to 1,500 mm to form a smaller 427-mm-diameter pipe to transport 1,000 T/hr of coal, which reduces the belt …
Force on Driver in Example Car Crash. For the car crash scenario where a car stops in 1 foot from a speed of 30 mi/hr, what is the force on the driver? Assume a 160 lb (mass = 5 slugs) driver. If firmly held in non-stretching seatbelt harness: Stopping distance 1 ft.
· For example, let''s say you have a scale that totalizes in tenths of a ton (0.1 tons per count) and you try to test it with a 1 ton material sample. If the scale is just about to increment to the next count (1.1 tons), the totalizer will read 1 ton when you actually have 1.0999 tons.
· The selection of pulley takes into account the wrap angle (180), belt speed (1.5 m/sec), method of belt strain, belt tension T, belt width (1200 mm) and type of splice of the conveyor belt. Pulley wraps length at terminals= 2 X Π X D 11.
3. BELT CONVEYORS - BASIC CALCULATIONS: 1. Mass of the Load per Unit Length: Load per unit length. Given the production capacity Qt = tph, the weight of the load per unit length (kg/m) – (lbs per ft) is calculated by: Wm = 2000. Qt or Wm = 33.333.Qt = (lb/ft) 60 x v v

· Calculation of Safe Working Load (SWL): For wire rope, FS is 6 for general purpose and 7 for heavy industry. A thumb rule formula is. SWL = (Wire rope dia)2 × 8 kgs. Example – For 12 mm dia wire rope. SWL = 12 × 12 × 8 = 1152kgs.
· If you don''t have BOD data, you can use your COD data and a COD/BOD ratio of 2.1 as a starting point. Use the 2.1 ratio value with caution though as it is highly variable from one wastewater system to another. The equation below assumes you also don''t have MLVSS data so you can use your MLSS data estimating that the MLVSS is 72% of the MLSS.
· Heating airflow can be calculated several ways. The easiest method we have found is the cfm per 10,000 Btu of input method. Example: An induced draft furnace should move 130 cfm per 10,000 Btu at sea level. So, say we have a 100,000 Btu Input induced draft furnace.
· Capacities for conveyors usingother troughing angles or materials can be obtained by multiplying the capacity shown in Table 3 by theappropriate CAPACITY FACTOR obtained from Table 1 below.3 equal roll idlers: Capacity - tonnes per hour = Capacity (Table 3) x Material Density (kg/m3) x Capacity factor (Table 1) x Belt Speed (m/s) / 1000 ...
3.1 Introduction. The unit cost of logging or road construction is essentially derived by dividing cost by production. In its simplest case, if you rented a tractor with operator for $60 per hour - including all fuel and other costs - and you excavated 100 cubic meters per hour, your unit cost for excavation would be $0.60 per cubic meter.
Then its capacity considered is ( (1x10)/0.04125) = 242.4242 m 3 / day. That means, a hydraulic excavator can excavate 242.4242 m 3 of soil in one day. Its cost per day including driver and fuel is Rs. 5000. Then the cost of 10m 3 of excavation can be calculated as: No. of days required for 10m 3 excavation = 10/242.4242 = 0.04125 days.
