A rod mill is a type of mill in which the grinding material loaded inside the cylinder is a steel rod. The rod mill is an asynchronous motor connected to a small gear through a

reducer, which directly drives the surrounding large gear to decelerate and rotate, driving the rotating part to rotate. The cylinder is equipped with an appropriate grinding medium, a steel rod, and the grinding medium is continuously fed into the cylinder by the feeding department under the action of centrifugal force and friction. The grinding medium is crushed by the moving grinding medium, and the product is discharged from the machine through overflow and continuous feeding force, To proceed to the next stage of processing.

Application scope

Widely used in primary grinding of artificial stone and sand, mineral processing plants, chemical plants, and power departments.

Main structure

The mill is mainly composed of a motor, main reducer, transmission part, cylinder part, main bearing, slow transmission part, feed part, discharge part, annular seal, thin oil lubrication station, and basic part for gear spray lubrication. The main reducer has a parallel shaft and a hard tooth surface.

Performance &characteristics

1. Power saving: Compared to older equipment, it saves over 40% of power. The particle size of the product is relatively uniform, with fewer coarse particles and

slime. Compared with the particle size characteristics of rod mill products and ball mill products, the particle size characteristic curve of rod mill products in

open circuit operation is almost the same as that of ball mill products in closed circuit operation.

2. Uniform discharge and high output: Advanced controllable inlet and outlet rod mill technology is adopted, combined with suitable grinding materials for

actual users. The traditional ball mill's surface contact is changed to line contact, ** the discharge particle size of the sand ** machine more uniform

and higher in output, suitable for ores with different hardness (Mohs hardness 5.5-12).

Comment:

The main power of the MBZ2736 and above sand ** rod mill in the table is selected according to the synchronous motor specifications. If an asynchronous

motor+reducer is used, the main power selection is more accurate and reasonable.

2. The processing capacity in the table is for medium hardness sand and gravel. The specific gravity of the sand and gravel pile is 1.6t/m3, the feed particle size is -20mm, and

the discharge particle size is -5mm. 3. The weight of the entire machine does not include the weight of auxiliary components such as the main motor, high and low voltage

electrical control parts, and rod loading devices.
