Ball mills and rod mills are grinding equipment widely used in concentrators The two have similarities in shape and grinding principles but there are differences in structure performance and use This article analyzes their similarities and differences from seven aspects and tells you how to choose ball mill 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

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded For an equivalent grind a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore The rod charge must be maintained in good working condition and broken and worn rods must be removed Rod mills usually require greater operator attention It is important

Ball mills are often operated at higher speeds than rod mills so that the larger balls cataract and impact on the ore particles The work input to a mill increases in proportion to the speed and ball mills are run at as high a speed as is possible without centrifuging

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

BallRod Mills have heavy rolled steel plate shells which are arc welded inside and outside to the steel heads or to rolled steel flanges depending upon the type of mill The double welding not only gives increased structural strength but eliminates any possibility of leakage

Ball mills are a similar shape to that of the rod mills except that they are shorter with length to diameter ratios of 1 to 15 As the name implies the grinding media in these mills are steel balls The particles size of the feed usually does not exceed 25 cm

A ball mill is a cylindrical device used in grinding or mixing materials like ores chemicals ceramic raw materials and paints Ball mills rotate around a horizontal axis partially filled with the material to be ground plus the grinding medium Different materials are

In the ball mill commonly used have the lattice ball mill and overflow ball mill named from different drainage structure and the rod mill does not use the grid plate drainore only overflow type and opening type two kinds the diameter of the hollow shaft at the drainage and  end is generally larger than the same specification ball mill

Nov 23 2019 · Recommendation of ball mill and rod mill Ball mill and rod mill are suitable for different materials 1 Selection by materials hardness Ball mill has a strong adaptation of material and it is suitable for grinding hard materials such as slag iron ore copper ore etc Rod mill is suitable for grinding brittle material such as rare metals

ball and rod mills Effective means for grinding and blending materials in preparation for mineral liberation from rock to dust Available at a small to large scale

Rod mill Unlike the ball mill the grinding medium in the rod mill is a steel rod so the working characteristics are significantly different from those of the ball mill Since the steel balls are in point contact the steel rods are in line contact

What is the difference between the ball mill and rod mill I’m just not sure that you will believe this leap of logic A ball mill contains balls A rod mill contains rods

The Ball Mill and Rod Mill Modules are used for fine grinding of solid matter by impact and friction in wet or dry condition The drum which contains the sample

BallRod mill Literature The BallRod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level They are the most effective laboratory mills for batchwise rapid grinding of mediumhard to very hard samples down to finest particle sizes

The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter Figure 811The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight

A ball mill is a cylindrical device used in grinding or mixing materials like ores chemicals ceramic raw materials and paints Ball mills rotate around a horizontal axis partially filled with the material to be ground plus the grinding medium Different materials are

Grinding mills spare parts Your mill is at the heart of your production process When a part fails you need to make the right decision to get your plant up and running Metso provides grinding mill parts for equipment previously sold under a variety of trade names and has OEM parts to fit seamlessly with your existing mill and process

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 rod mill to tell you how to choose the ball mill and rod mill

The mill product can either be finished size ready for  processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill AGSAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill

A ball mill a type of grinder is a cylindrical device used in grinding or mixing materials like ores chemicals ceramic raw materials and mills rotate around a horizontal axis partially filled with the material to be ground plus the grinding medium Different materials are used as media including ceramic balls flint pebbles and stainless steel balls

Whereas a SAG and ball mill may be ideal for larger operations the Rod Mill is ideal for low tonnage applications Product Features Durable lowfootprint Rod Mills
