Typical tonnage factors can range from 2 to 8 tons per square inch, depending on the material. For example, if we have a 6" X 6" part, the surface area is 36 square inches. Let''s further assume that our material calls for a 5X mold clamp factor. 36 times 5 equals 180, so based on our calculations up to this point, we will need to run these parts on an injection molding machine capable of

Andesite with an estimated production of about 120,000 tonnes per month. What is the estimated requirement of explosives per month? Assume that the SG of Andesite is and the powder factor for andesite is kg/m3. Solution: Volume of andesite to be produced = 120,000/ = 44,444 m3 Explosives required = 44,444 x = 31,111 kg . 7 Backbreak or overbreak: This is when the
Calculating availability of machinery is one of the crucial considerations for ensuring a company''s stellar performance. Calculate availability of machinery as one component of overall machinery productivity performance. Establish the total available hours for the machine. This can be represented by the total number of hours the machinery can be used in a day or shift normally 8, 10 or 12
used to determine machine productivity. It shows how to calculate production onthejob or estimate production offthejob. Machine performance is usually measured on an hourly basis in terms of machine productivity and machine owning and operating cost. Optimum machine performance can be expressed as follows: Lowest Possible Hourly Costs Lowest cost per ton = _____ Highest Possible Hourly

Estimating 6 working hours per day, the total man hours is obtained from multiplying the following: 15 x 10 x 6 = 900 hours. Therefore, productivity is equal to 800/900 = units per hour. As we know with the cost of manhours, it is easy to calculate how the labor force contributes to the unit cost and the profitability of the product line.
SCREEN CAPACITY CALCULATION by Larry Olsen and Bob Carnes TJCI201 SCREEN CAPACITY CALCULATION . ASTEC encourages its engineers and executives to author articles that will be of value to members of the Aggregate, Mining and Recycle industries. The company also sponsors independent research when appropriate and has coordinated joint authorship between industry competitors.
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically – m (2 ft 0 in–3 ft 3 in) thick). The longwall panel (the block of coal that is being mined) is typically 3–4 km (– mi) long and 250–400 m (820–1,310 ft) wide. History. Plan of longwall mine before conveyors – the hoist is at the center of the central
Total 200 machines and the working shift is 10 hours per day. Total factory capacity per day is 2000 hours (200 machines * 10 hours). If the factory is producing only one style (Shirt) of SAM 25 minutes and used all 200 machines daily production capacity at 50% = (2000*60/25)*50% Pieces = (2000*60*50) / (25*100) Pieces = (/2500) Pieces

Coal Transportation Since the distance between the energy supply point and the energy demand point for coal is often long, many coal utilization projects require that transporta tion technology and costs be considered. For long distances the cost of transpor tation can greatly exceed the mining cost. As the nation uses and exports greater amounts of coal from more remote locations, coal
Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the
The average load on the axle is 75 tonnes which is tonnes per tyre. If the average speed of the truck is 20km/h, the tyre rating would need to be *20 or 750 TKPH in order to not be a limiting factor. How TKPH affects haulage in Spry. TKPH is calculated per schedule step. If the calculated TKPH is higher than the tyre''s rating, TKPH
Calculate the annual costs of these, then divide by total labor or machine hours for the year. This will be your overhead cost per hour This will be your overhead cost per hour Once the above costs are calculated you can use the formulas and guidelines below to arrive at either a "general" shop hourly rate or an hourly rate based on a specific piece of equipment.

If a single machine rate were used to estimate the unit cost for truck transport and this value was converted to a tonkm cost or /m 3km cost without removing the "fixed" cost of loading and unloading then the "variable" cost of transport would be overestimated. This could lead to erroneous results when choosing between road standards or haul routes. Animal Rates. The calculation of the
Basically OEE is about (as the name says) effectiveness: it is the rate between what a machine theoretically could produce and what it actually did. So the fastest way to calculate it is simple: If you take the theoretical maximum speed (for example 60 products per minute) you know that at the end of a 480 minutes shift there should be 28,800
Machine Hours Rate: Formula and Calculation (With Illustration) Article shared by: ADVERTISEMENTS: If factory overhead is Rs 3, 00,000 and total machine hours are 1,500, the machine hour rate is Rs 200 per machine hour (Rs 3, 00,000 ÷ 1500 hours). Advantages: This method can be used advantageously where the machine is the major factor in production. In capital intensive
Powder Factor = Tons of rock (or cubic yards) per pounds of explosive. Normal range = 4 to 7 Shallow holes = 1 to 2 External loads = .3 Tons of Rock = Powder Factor lbs of Explosives The higher the powder factor, the lighter the load. Lower powder factor means more explosives. Example: tons = PF of BURDENSPACING CALCULATION From Powder Factor of 1 lb./ 1. Determine borehole
