The feed is at one end of the cylinder and the discharge is at the other. Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing. Industrial ball mills can be as large as m (28 ft) in diameter with a 22 MW motor, drawing approximately % of the total world''s power (see List of countries by electricity consumption). However, small versions of ball
Ball mill and rod mill are the common grinding equipment widely used in the mineral processing plant. They are similar in shape and grinding principle, but also different in structure, performance and application. Here are seven differences between ball mill and
Sep 28 2018#183; Ball mills and rod mills are both excellent mining machines for grinding ores into fine powders and of ball mill machine for gold ore stone crusher Gold Ore Wet Plant Ball . Chat Online; Function Of A Mining Ball Mill. Function Of A Mining Ball Mill . function of a mining ball millbnbinc. the function of ball
Here are seven differences between ball mill and rod mill to tell you how to choose the ball mill and rod mill. According to the grinding mechanism, the grinding media (steel ball or steel rod) in the cylinder is lifted to a certain height with the cylinder rotation under the effect of friction force and centrifugal force, then falls down with a certain line speed, which has a grinding impact
The 21 Liter (5 gallon) 911METALLURGY 911MPE21BM dual function Laboratory Rod Mill / Ball Mill is designed to meet the industrial requirements to grind coal, cement and a wide variety of ores. The dual duty Laboratory Grinding Mill consists of a gear motor mounted on a high precision solid steel underframe complete with outlet funnel and a set of separation screens plus sample collector.
1/1/2016#0183;#32;This is a normal setup as the primary function of a rod mill is to provide a uniform sized feed to the ball mill. Figure shows that the rod mill product is classified and a more uniform feed size is, therefore, discharged to the ball mill whose primary function is to reduce the size of ore, suitable for downstream use. Such a circuit increases the efficiency of the ball mill grinding.
Rod Mill Grinding Machine Ball Mill(id ). Buy China . Rod Mill Grinding Machine Ball Mill The rod mill is driven by motor with speed reducer and peripheral large gear or low speed synchronous motor with peripheral large gear. The grinding medium steel rod is put into the cylinder which is lifted and then fall under the action of . Get Price; Bond Index Ball Mill / Rod Mill BT 100 XLRETSCH
The Operating Principle Of The Ball Mill. Energy consumption for ball mills is a function of many factors the physical properties of the ground material its specific gravity and hardness the degree of drum filling by grinding balls the number of drum rotations etc ball mills have low efficiency no more than 15
19/11/2019#0183;#32;The rod mill adopts overflow type and open type discharge, does not use grate type discharge. The diameter of the rod mill discharge end is larger than that of the same size ball mill. When the rod mill speed is lower than the working speed of the same size ball mill, the medium in the rod mill is in a sloping working state.
Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill. The action of other grinding
Sepors 16 x 32 continuous ball or rod mill is ideal for pilot plant studies of ore grinding and processing or just regular small scale grinding requirements you may have. The mill can be used in a closed circuit, with a spiral classifier, screen or cyclones or as a single pass grinding mill. The spiral classifier is popular in pilot plant grinding
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.
more function mining machine ball mill. A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is
The grinding medium of the ball mill machine is steel ball (or alumina ball, zirconia ball, etc.), the grinding medium of the rod mill is steel rod, and the autogenous mill doesn''t need the grinding medium, it achieves the grinding effect through the collision of the material itself, and the gravel mill achieves the grinding through the gravel to the material.
200350mm. Product improvement. Highefficiency autogenous mill can realize the second and third stage crushing and screening, and part or all crushing and grinding of rod mill or ball mil. Low power consumption, no dust pollution, less auxiliary equipment, easy

The rod mill usually uses 50100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium. The length of steel rod is 2550mm shorter than the cylinder, and it is usually made of high carbon steel with carbon content of % 1%; the loading capacity of rod is about 35% 45% of the effective volume of rod mill.
