Rod Mill

Production Capacity: 0.62-180t/h Feed Granularity: ≤50mm Motor Power: 18.5-630KW

The rod mill is a type of mill that uses steel rods loaded inside the cylinder as grinding media. Our company employs advanced controlled feeding and discharging technology, combined with suitable grinding media tailored to the actual grinding materials. By transforming the traditional surface contact into line contact, the discharge particle size becomes more uniform, the output is higher, and the price is more reasonable. It is widely applicable in industries such as metallurgy, chemicals, glass, and refractory materials, where high uniformity of the ground finished product is required. Applicable materials: pebbles, quartz sand, limestone, dolomite, granite, monazite, gold ore, iron ore, etc.

PRODUCT INTRODUCTION

Rod mills are generally of a wet overflow type and can be used as primary open circuit grinding. They are widely used in mineral processing plants, chemical plant power departments, and for grinding artificial stone sand. The mill consists of several parts, including a motor, main reducer, transmission department, cylinder department, main bearing, slow speed transmission department, feeding department, discharging department, ring seal, thin oil lubrication station, large and small gear jet lubrication, and foundation department.

ADVANTAGE

Power saving.Rod mills can save over 40% in power consumption compared to old-type equipment. The product size is more uniform and contains less coarse particles and mud.
Wide range of application.The equipment is suitable for ores of different hardness (Mohs hardness 5.5~12).
Adjustable discharge fineness.Simple adjustments can easily adjust the discharge fineness. The equipment is equipped with an embedded fineness control device and a sieving device to ensure that neither excessive fineness nor more unqualified products will be mixed into the finished product.
Uniform discharge and high output.Our rod mill is designed with advanced controlled inlet and outlet technology, utilizing a line contact method instead of the traditional surface contact method used in ball mills. We take into account the user’s grinding material and select a suitable grinding body to make the discharge size more uniform and increase the output.
Environment friendly.It is a low-noise and pollution-free machine suitable for artificial sand-making and coarse grinding of ores in mineral processing plants.
Avoid excessive grinding.Due to its high performance, the rod mill is often used for rare metal ores like tungsten and tin in re-election or magnetic separation plants. Rod mill sand-making machines are commonly used to prevent over-grinding hazards.

WORKING PRINCIPLE

The rod mill is an asynchronous motor connected with a small gear through a reducer, which directly drives the surrounding large gears to decelerate and rotate, and drives the rotary part to rotate. The cylinder is equipped with an appropriate grinding medium—steel rods. Under the action of the machine, the material to be ground continuously enters the inside of the cylinder from the feeding part, is crushed by the moving grinding medium, and the product is discharged out of the machine through the force of overflow and continuous feeding, so as to proceed to the next process deal with.
