VSI sand maker, also called VSI crusher, is the major machine for sand making plant.
Ball mill is the key machine to grind the crushed materials. Ball mill machine is widely used to process cement, silicate product, building material, refractory material, fertilizer, ceramics and glass, etc.
On the basis of domestic mills, fote raymond mill is produced. The raymond roller mill enjoys the features of high working efficiency, low energy consumption, small floor space and small cost.
Configuration of ball mill and rod mill. the proportion of cylinder shape is different. the cylinder length-diameter ratio of rod mill is generally 1.5-2.0, while the cylinder length-diameter ratio of ball mill is smaller, only slightly greater than 1.
Technical performance and application of ball mill and rod mill author:dahua1 time:2018-10-10 . ball mill. it is a low level forced discharge type grinding equipment. the slurry stored in the mill has less pulp, and the fine particles can be discharged in time, so that the possibility of over-grinding is small. at the same time, due to the grid ...
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.
Jan 01, 2016 in recent times, these mills have successfully replaced the conventional rod mill–ball mill configurations. in australia, the number of ag/sag mills increased from about six in 1984 to more than 40 in the following 5-year period . the number of installations worldwide by mid 1989 was about 471, and presently the number is growing.
A rod mill differs from a ball mill in that the comparatively rigid grinding media operate in a relatively fixed path and reduction results fram line rather than point contact between grinding surfaces. conventional rod mills are either high or law discharge. in the high discharge mill, the discharge trunnion. is. the same size or only slightly

Sepor’s 16 x 32 continuous ball or rod mill is ideal for pilot plant studies or small scale milling. the unique hinged ‘torpedo tube’ end plate on the discharge side allows the unit to be changed from continuous to batch mode within minutes.
Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. ball mills may be primary or secondary grinders. primary grinders are fed from crushers such as a jaw crusher. secondary grinders are fed from other grinders e.g. a rod mill. ball mills are usually either of the grate (diaphragm) or overflow type.
The rod mill usually uses the steel rod with a diameter of 50-100mm as the grinding medium, while the ball mill usually uses the steel ball as the grinding medium. the steel balls of ball mill are in point contact, while the steel rods of rod mill are in linear contact, so …
Rod mill is widely used grinding mill to grind all kinds of ore and rocks in metal and nonmetal mining, water conservation, building materials,sand making industry and so on. rod mill grinds ore into fine size, the output could be reach 0.2mm-5mm. it often worked in first-stage grinding before ball mill.
Apr 10, 2017 rod mill b. ball mill c. tube mill 3. # rod mill • description the rod mill is a tumbling mill but having a large percentage of its volume (30 - 40%) loaded with steel rods. the rods are placed axially in the mill and are loose and free to move within the mill. 4. # inside & the outside of a rod mill 5.
Recommendation of ball mill and rod mill ball mill and rod mill are suitable for different materials 1. the daily maintenance requires constant addition of a certain amount of steel balls, while the rod mill only needs to be inspected and replaced in a period of time.the product of the rod mill is rough, but the particle size is uniform, coarse particles and slime are less, the over ...
Aug 17, 2018 rod mills — these rotating mills use rods for grinding media causing friction and attrition between steel rods and ore particles. rod mills can accept feed up to approximately 50 mm. (2 in.) and ...
Introduction. the rod mill is loaded with the grinding media of steel bars. it consists of five parts including cylinder shell, feeding system, discharge system, main bearing and transmission system. it is available for both of the dry grinding and wet grinding fashion as the customer’s needs.

Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. it is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. figure 2 shows that there is no linear relation between
The ball and rod mill type lmbrm is a process and laboratory machine, which is suitable for milling and homogenizing soft, fibrous, hard and brittle materials in dry and wet phase. the lmbrm is suitable for normal and bond grinding, depending on the (size) drum. because the machine has a changeable opening, different sizes of drums can be ...
Open circuit rod mill-open circuit ball mill. this configuration is employed when it is desired to produce a final ground product having a very high pulp density. this situation can be useful for various types of leaching circuits but does not normally apply to flotation concentrators. single stage ball mill. single stage ball milling has proven to be very popular in recent years.
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.
Jan 14, 2019 rod mill liners are also generally of alloyed steel or cast iron, and of the wave type, although nihard step liners may be used with rods up to 4 cm in diameter. lorain liners are extensively used for coarse grinding in rod and ball mills, and consist of high carbon rolled steel plates held in place by manganese or hard alloy steel lifter bars.
Although they have the similar working principle, there are many differences between ball mill and rod mill on details. 1. configuration of ball mill and rod mill. the proportion of cylinder shape is different. the cylinder length-diameter ratio of rod mill is generally 1.5-2.0, while the cylinder length-diameter ratio of ball mill is smaller, only slightly greater than 1.
Sizes are limited to 3’6” x 4’ for steel ball mills, and 4’ x 5’ for lined mills. “td” mills are available with or without water-jacketing. continuous feed and discharge mills. patterson offers a variety of continuous ball, rod, and pebble mills for open or closed circuit grinding applications.
Grinding medium of rod mill. grinding medium of rod mill. the rod of diameter from 50 to 100 mm is often used as the grinding medium, and the filling rate of rod mill is 35% to 45%, while filling rate of ball mill is 40% to 50%. rod is mainly made of several materials: a high carbon steel.
