is a rod mill an open circuit
rod ball mill closed circuit
Figure shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier. This is a normal setup as the primary function of a rod mill is to provide a uniform sized feed to the ball mill.
BASIC ENGINEERING SURVEYS FOR CONSERVATION .
A backsight is a rod reading taken on a point of known elevation. It is the first reading taken on a bench mark or turning point. Backsights are sometimes recorded in the (+) column, because they are added to bench mark and turning point elevations. A foresight is a rod reading taken on any point on which an elevation is to be determined.
Mill (grinding) Wikipedia
F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.

In the above circuits, material is fed from hoppers to ball mill to reduce the size to microns. In closed circuit, micro particles are fed to classifier for segregation of desired material (based on its size). The rejected ones are once again passed through the ball mill. In open circuit, however, segregation through classifier is not considered.

AMIT 135: Lesson 8 Rod Mills – Mining Mill Operator Training
Reading Lecture. Introduction. Used as the primary comminution unit in a grinding circuit. Rods are placed parallel along the length of the rod mill. Rods are 150mm shorter than the mill length. Breakage occurs more from cascading than cateracting. The product size distribution is narrower than a ball mill but significantly coarser.
Grinding in Ball Mills: Modeling and Process Control
Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.

Main Features of a modern Wire Rod Mill – IspatGuru
Jan 03, 2014· Modern wire rod mills are high speed mills capable of rolling of smaller dimensions at high production rates, while at the same time keeping investments and operating costs at the reasonable levels. As a rule, wire rod mills are designed for an annual output of between 300,000 t and over 800,000 t (two strand mills).

Circuit Diagram For Ball Mills And Rod Mill
Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.
