H W T Calculate Crushing Ratios Of Coal
Reduction Ratio/ Milling Stages Calculator
· Total reduction ratio. Source: metso. Crushing is done in three, or four stages while grinding is done in one, or three stages. If you don't have many stages as shown on the app put 1 in the stages that you are not using. Calculate the total reduction ratio of a milling circuit by multiplying the reduction ratios of every stage.
Determining Stripping Ratio
· SR (Overall) = Volume of Waste/Volume of Ore. For Example: Determine the Stripping Ratio of the ore section (green zone) shown below: We know; SR = Waste/Ore, therefore; SR = 2500/5000 = 1:2 ( ) ( one unit of waste is removed to recover 2 units of ore) Note: We proceed by determining the area of waste materials by calculating the ...

The strength of hardrock pillars
design of coal pillars is ''backcalculation'', an approach that has been used extensively in geotechnical engineering [2]. This approach has led to the development of empirical pillar strength formulas but can only be implemented by observing and documenting failed pillars. The design of hardrock pillars has not received the same research attention as coal pillar design. This is ...
USING THE POINT LOAD TEST TO DETERMINE THE UNIAXIAL ...
the Coal Mine Roof Rating (CMRR). INTRODUCTION The point load test (PLT) is an accepted rock mechanics testing procedure used for the calculation of a rock strength index. This index can be used to estimate other rock strength parameters. The focus of this paper is to present the data analysis used to correlate the point load test index (Is50) with
How to Calculate Ratios: A StepByStep Guide ...
· This makes it easier to use the ratio to inform your calculations. Ratios are used in maps to provide scale. Usually expressed as 1:10,000 or similar, this tells you that for every 1 unit on the map, the real distance is 10,000 units. If you measure 1 cm on the map, the real distance would be 10,000 cm (or 100 m). Ratios are also used in drawings, such as architectural designs, to show perspec

Rankin's Formula Example for Column Crushing/Buckling Load ...
· If column is short, calculated load will be known as crushing load. And load will be buckling or crippling load, in case of long column. This formula only gives the ultimate load, but columns are design on safe load. In order to get safe load, divide ultimate load ( Load obtained from Rankin's Formula) with factor of safety (). Rankin's Formula. Mathematically, Rankin's formula can ...
