Dry Rod Mill

What is Dry Rod Mill?

Rod mill can be divided into dry rod mill, wet rod mill. Different from the ball mill is built-in rod mill is a steel rod type grinding body, the use of cylinder cyclotron rotation generates centrifugal force, the steel rod will be raised to a certain height and then thrown down to the ore impact crushing to achieve the grinding effect. Rod mill can also do fine crushing work, processing softer or hardness of the ore, configuration is simple and low cost, can be better to 19-30 mm ore grinding to 6-10 mesh.

In an open circuit grinding operation, the product size performance of a dry rod mill is almost comparable to that of a ball mill in a closed circuit grinding operation.

If you are a beginner and do not know about Dry Rod Mill, tell us your raw material characteristics, finished product requirements, site conditions, production budget, hourly production, and other requirements, we have professional engineers to equip you with a suitable model at a reasonable price. Next, let’s see the types of Dry Rod Mill we can supply.

What Is Dry Rod Mill Used For?

Rod mill is used as the initial open circuit grinding, suitable for nonferrous metal, ferrous metal, nonmetal ore dressing site and chemical industry, building materials and other industries grinding materials to use.

For example: Dry rod mill in a foreign sand and gravel plant processing plant, mainly responsible for open circuit grinding operations, feed size 45mm, discharge size 0.21mm, capacity of 150t/h, the overall effect is good, strong processing capacity, the current customer response all good.

Working Principle of Dry Rod Mill

The working principle of dry rod mill is the same as that of wet rod mill, which is to drive the cylinder to rotate through the motor and peripheral large gear deceleration drive. The cylinder is equipped with appropriate grinding media – steel rods. Under the action of centrifugal force and friction, the grinding media is lifted to a certain height, and falls down in the state of throwing or draining. The material to be ground enters into the inside of the cylinder continuously from the feeding port, is crushed by the moving grinding media, and the product is discharged out of the machine by the force of overflow and continuous feeding for the next section of the process operation.

Advantageous features of Dry Rod Mill

• Dry rod mill grinding particle size uniformity, in the open circuit grinding operation of the product size performance and ball mill closed circuit grinding operation state is almost the same.
• Advanced controllable feeding and discharging technology, combined with the actual user’s grinding materials with the appropriate grinding body, changing the previous surface contact to line contact, so that the rod mill discharge size is more uniform.
• Dry rod mill discharge size can be adjusted according to customer demand, there is a fineness control device, and the discharge can be added screening device to ensure that neither over-grinding nor unqualified products mixed into the finished product
• Dry rod mill material particle size characteristics related to its grinding situation, when the steel rod and ore impact, friction, the first will be polished coarse material, and then grinding smaller ore particles, so reduce the phenomenon of over-crushing.
• When the steel rods along the liner plate to the rise, between the coarse particles, as if the bar sieve, so that the fine particles from the gap between the rods through, which is also conducive to clamping the coarse particles, and make the coarse particles are concentrated in the steel rods sharpening place, therefore, the rod grinding product is more uniform.
