The 700t/d Gold Concentration Plant in Sudan is designed by Henan Fote Heavy Machinery Co., Ltd. Fote Machinery has provided the whole service including ore beneficiation test, plant design and construction drawing design, complete equipment manufacture a

In this plant, gold ore is mainly natural gold among the ore to be processed, but it is mostly distributed in the crack of poisonous sand, pyrrhotite and quartz crystal gap, which significantly improves the processing difficulty of the gold ore. The custo

Open circuit grinding consists of one or more grinding mills either parallel or in series that discharges a final ground product without classification equipment and no return of coarse discharge back to the mill Some very simplistic examples of open circuit grinding are see below and are made of a Rod mill Ball Mill or a Rod mill ball mill combination

Apr 15 2004 · The characteristic differences between open and closedcircuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier For the same median diameter of the product the rate of powder production in the closedcircuit is about 5 higher than that of the opencircuit

operate the mill in open circuit greatly simplifies the operating and maintenance strategies of the circuit Figure 4 illustrates a typical IsaMill product distribution in open circuit at varying power inputs – note the steepness of the curve and the lack of ultra fines that would be expected from a Tower Mill

The GD and 2D hammer mills are designed for the animal feed industry to grind raw materials into small particles and meal Both the GD and 2D hammer mill series cover capacities ranging from 5 – 100 tons per hour dependent on type of raw material formula and required grinding structure and can be incorporated in a pregrinding as well as a post

In open circuit grinding passage of material is only once through the mill Consequently a consistent product fineness is difficult to achieve Installations having a hydraulic roll press prior to mills are common In closed circuit grinding a high efficiency separator OSepa or Sepax Sepol is in operation which separates the material

Open Circuit Configuration Page Content While other grinding require closed circuit cyclones and high recirculating loads the IsaMill achieves a much steeper product sizes distribution in only a single pass Feed to the IsaMill passes through 8 consecutive grinding stages between the discs before it reaches the internal classifier

Question A Twostage Grinding Circuit Using A Rod Mill In An Open Circuit With A Ball Mill In A Closed Circuit With A Cyclone Classifier Is Used To Grind 100 Tonnes Per Hour Of Ore SG 3 The Circuit Layout Is Illustrated In The Figure Below Assuming That The Circuit Is Sampled And The Results Are Shown In The Table Below Rod Mill Discharge Ball Mill

In a simple grinding circuit there will be a ball mill and a classifier Some circuits especially in large mills have more units or two or three stages of grinding but whatever is said here will apply to the complicated circuits as well as the simple ones The two types of ball mill in general use are the grate mill and the openend mill

Autogenous grinding or semiautogenous grinding mills can be operated in open or closed circuit However even in open circuit a coarse classifier such as a trommel attached to the mill or a vibrating screen can be used The oversize material is recycled either externally or internally
