Although it was developed nearly 50 years ago, Bond's method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. This paper discusses the basic development of the Bond method, the determination of the efficiency correction factors based on mill dimensions and feed characteristics, and the application of the results to designing grinding circuits.
M = tonnage of ore in mill discharge and Ds, Do, and Dm are the liquidtosolid ratios of the sand, overflow, and classifier feed at the points where they leave or enter the classifier. Then circulating load ratio = (DoDm)/ (DmDs) (8) And circulating load tonnage = F (DoDm)/ (DmDs) (9)
Haßfurt ( German pronunciation: [ˈhasˌfʊʁt] ⓘ; English: Hassfurt) is a town in Bavaria, Germany, capital of the Haßberge district. It is situated on the river Main, 20 km east of Schweinfurt and 30 km northwest of Bamberg. In 1852, Ludwig's Western Railway reached the town and between 1892 and 1995, which also had a branch line to Hofheim.

The processing plants have followed suit with large 42 ft diameter mills, 500700 m 3 flotation cells along with larger dewatering and tailings pond facilities. The trend of increasing throughput and larger equipment is continuing despite all associated challenges along with an ongoing trend of extremely high waste generation.
There are places to stop for refreshments along the route. The starting point of the route can be reached by bus and train (Bahnhof Zeil am Main).
The primarily used equipment in crushing are jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, usually closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant.
