Introduction- What is grinding media?

Grinding media are instruments used to break down or pulverize material in a mill. This could be material from mining, construction materials and more. It comes in different forms such as:

• Alumina oxide balls
• Cast-iron balls
• Ceramic balls and cylinders
• Soda lime glass.

We have three types of grinding media which we produce at Camasteel:

●    Forged steel grinding balls

Steel balls are components used as grinding media and as a rolling mechanism in rotary motion components like wheels and bearing. Steel balls are commonly used in automobiles for semi-precision bearings, as well as for other commercial uses.

●    Cast iron grinding balls

Cast iron grinding balls are grinding media with the geometric shape of a ball. They are manufactured  by casting molten iron tino chill molds or sand molds. They are used in large quantities in grinding mills for crushing coal, ores, cement, and many other objects.

●    Steel grinding rod

Grinding rods are a type of grinding media, made of steel, that has gone through specific degrees of heat treatments to enhance the wear and impact resistance of the material. Grinding rods are usually used in rod mills.

What is a Steel Grinding Rod?

Steel grinding rods are high quality steel rods that have undergone various heat treatments to maximize the wear and impact resistance.

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.

What is a Forged Steel Grinding Ball?

Forged Steel Grinding Balls are used in metallurgy and gold mining for grinding the ores. It is used for enrichment of extracted raw materials in drum mills. It used for the preparation of pulverized coal

Forged Steel Grinding Balls

What is a  Steel Ball Mill?

The ball mill is made up of a hollow section that spins down either a horizontal or a vertical axis. The section is packed with balls. The materials to be crushed are added and the balls move around inside the mill, colliding with the materials. Grinding balls are used to grind materials into fine powders.

Ball Mill for Mining

What is a Steel Grinding Rod Used For?

Steel Grinding Rods are used in metallurgy and mining for grinding metal ores such as iron, copper, and gold. Further uses are listed below:

• It is used for the processing of extracted minerals.
• It can be used for grinding coke and friable non-metals.
• It is used to grind material for glass.
• It is also used to grind gravel to produce sand

Fine Crushing

Rod mill can be used as the fine crushing equipment to replace short-type cone crushers when crushing soft ores. It has a simple configuration, less costs and low dust pollution, which can save a lot of investment in dust removal machines.

Prevention of Over-Crushing

When the tungsten ore, tin ore or other rare metal ores are selected by gravity separation or magnetic separation, rod mill is often used to prevent over crushing.

Preliminary Grinding for Larger Capacity

In the two-stage grinding process, rod grinding machine is generally used as the first grinding equipment, which has the advantages of larger production capacity and higher efficiency.

What are Steel Grinding Balls used for?

Steel Grinding balls are used in the mining, coal, construction (for example, to make cement) and other industries: in ball mills as grinding bodies for grinding materials by impact, abrasion and crushing. Some of the uses are listed below:

• It is used for enrichment of extracted raw materials in drum mills.
• It is used for the preparation of pulverized coal.
• It is used for grinding materials for pottery in ball mills.
• It is used for making cement in cement industries.
• It is also used for oil processing.

The uses can also be placed into categories. Let's take a further look:

Steel balls for mining

Ball mill has a wide range of applications. It can grind metal ore and non-mental ores, which is suitable for hard materials, such as quartz, gold ore, copper ore, iron ore, potash feldspar, etc.

Construction and Industrial uses of steel balls

A steel ball mill can also be applied in the industries such as cement, construction materials, fireproofing materials, chemical fertilizer, ore beneficiation, glass and ceramics. And the fineness of the finished product can reach 800 meshes.

What is the difference between Steel Rods and Steel Balls?

The difference between grinding media steel rods and steel balls is that the ball mill and the rod mill are suitable for grinding different materials. This along with characteristics like the density and size of each product differentiates them.

Quality Steel Grinding Balls and Steel Rods For Mining

These differences between steel balls and steel rods can be measured by:

1. Selection by material's 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.

2. Selection by required particle size

The steel ball and the mineral material are in point contact, so the finished product has a high degree of fineness, but it is also prone to over-grinding. Therefore, it is suitable for the production with high material fineness and is not suitable for the gravity beneficiation of metal ores. When the required particle size of the finished product is less than 0.5mm, it is recommended to use a ball mill.

The steel rod and the material are in line or surface contact, and most of the coarse particles are first crushed and then ground. Therefore, the finished product is uniform in quality, excellent in particle size, and high in qualification rate.

When the finished product size is required to be 1 to 3mm, it is recommended to use a rod mill.

3. Selection by the work site

In the design of the dressing plant, it is usually necessary to design the floor plan of the grinding workshop in advance, so it is necessary to consider the shape and size of the equipment. The cylinder shape of the rod mill and the ball mill is different: the cylinder of the rod mill is a long type, and the floor area is large. The ratio of the length to the diameter of the cylinder is generally 1.5 to 2.0; The cylinder of the ball mill is a barrel or a cone. And the ratio of the length to the diameter of the cylinder is small, and in most cases the ratio is only slightly larger than 1, and the floor area is small, too.

Which is better- Steel Balls or Grinding Rods?

Due to the similarities of both steel rods and steel balls, it may be quite a task determining which is better. Both bring about efficiency but to decide which grinding media type is better for you, It should be considered whether the equipment installation conditions can be met when selecting.

Importing niche steel products, like steel balls, can not only be time consuming, but also daunting and confusing. Thankfully , Camasteel has strong company values that guides us to provide the best service possible and handle the entire importing process for our clients.

How to Choose Grinding Steel Balls?

The selection of grinding steel balls depends on the hardness and coarse particle size of the ore material. Harder material requires a steel ball of larger diameter for greater impact force.

How to Measure the Performance of Grinding Steel Balls?

The effectiveness of steel balls is determined by calculating the efficiency of the ball mill which considers multiple factors. The power per tonne of the ball mill is determined by the ball mill fill rate. Good Steel balls will have:

• Greater hardness
• Greater endurance and wear resistance
• Smooth surface
• The low circle loss rate
• And low splintering rate.

The Grinding steel balls supplied by Camasteel go through full-scale industrial tests that ensure abrasion resistance and robustness of the media.

What is the Price of Grinding Steel Balls?

The price of steel balls for grinding depends on the diameter. On average,  8mm stainless steel balls cost around $6 per Kg, and 20mm steel balls cost around $1000 per tonne. For heavier media, companies usually only entertain bulk orders.

What are the Advantages of Using Grinding Steel Balls?

Grinding steel balls deal with materials too hard for cast iron balls. They are most robust, have better surface quality, and have higher abrasion resistance.

Steel balls are a recommended choice for heavy-duty and long-term work.

How Big are the Balls in a Ball Mill?

Ball mill performance is critically dependent on the ball size. Larger balls are effective for large-sized and hard particles while smaller balls are effective for the breakage of lighter and fine particles.

How to Calculate Grinding Media in Ball Mill?

Generally, steel balls must not fill more than 35% of the ball mill. The size selection of grinding balls can be calculated using the following formula:

Dm <= 6 (log dk) * d^0.5

Here, Dm = the diameter in mm of a single ball.

d = the diameter in mm of the biggest ore piece ore in the mill.

What is a Grinding Rod?

Grinding rods are a type of grinding media, made of steel, that has gone through specific degrees of heat treatments to enhance the wear and impact resistance of the material. Grinding rods are usually used in rod mills. However, there are other types of grinding media, which include Cast Iron Grinding Balls and Forged Steel Grinding Balls. These different grinding media are differentiated in terms of shape and usage.

Quality grinding rods for bulk purchase

What are Grinding Rods used for?

Grinding rods are widely used in rod mills. They are essential steel products used for :

• Grinding materials for glass
• Processing of extracted minerals
• Grinding coke and friable non-minerals
• Grinding gravel to produce sand
• Grinding ores such as iron, copper and gold in the mining industry.

Quality forged steel grinding rod

What are Grinding Rods made of?

Steel grinding rods are manufactured from a specific steel which has the characteristic of breaking up without twisting when wear occurs. This property is essential in maintaining full grinding capacity and avoiding the difficulty of taking out wire-like, worn rods that usually twist and bend into a mass of intertwined wires, if breaking does not occur.

What are the Qualities of a Good Grinding Rod?

Good quality grinding rods have the following properties;

• Quality grinding rods have wear resistance effects up to 150% stronger, when compared on rolled steel bars.
• Grinding rods have high durability and strength.
• They do not crack or wear out easily.
• Grinding rods have high resistance to bending and breakage.

What is Rod Mill for Grinding?

Rod mills use long rods for grinding media. These rods are used in grinding ore by tumbling  within the mill. The act of grinding is by line contact with the rods extending the length of the mill. The spinning and tumbling of the rods in roughly parallel alignment results in the selective grinding of coarse materials and the reduction of slime production.

Wet Rod Mill for Grinding Raw Materials

What are the differences between Rod Mill and Ball Mill?

The differences between ball mill and rod mill can be analyzed in terms of performance, grinding medium and application. However, ball mill and rod mill are also quite similar in appearance, as both grinding tools have cylindrical structures.

Differences in performance

Based on performance, rod mills can be divided into three types; center and side discharge rod mill, end and side discharge rod mill, and shaft neck overflow discharge rod mill. These types of rod mills are differentiated by the part through which the rod mills are fed, as their names imply. However, ball mills are divided into two types, in accordance to their discharging ways, these types are the overflow discharge ball mills and the grate discharge ball mills.

Difference in grinding medium

Ball mills are made of materials such as high manganese steel, low carbon alloy and high carbon and high manganese alloy, giving the device its high toughness and manufacturability qualities. However, rod mills are made up of rods from high carbon steel and 42 Cr Mo steel. This rod, used as a grinding medium ,is usually 50 to 100 mm in diameter.

Difference in application

Basically, rod mill is used for coarse grinding, while ball mill is used for fine grinding. Ball mill is used in grinding metal ore and non-metal ore and also applicable in industries such as cement, construction, glass and ceramics, and chemical fertilizer industries. However, rod mill can be applied as a fine crushing equipment when crushing soft ores.

Ball Mill for Dry Grinding

Where to buy Grinding Rods?

You may be able to find grinding rods in small quantities in your area. But if you want to buy large quantities of grinding rod, it is preferable to import directly from the manufacturers. This guarantees the issuing of certifications and cost savings, making it better than purchasing grinding rods in small quantities locally or from a distributor.
