PRODUCT INTRODUCTION

Sand making rod mill, also referred to as rod mill, is one of the widely used sand and gravel equipment in the sand and gravel industry. It is mainly suitable for making abrasives, refractory materials, cement, quartz sand, steel sand, iron ore, slag powder, For the fine and medium crushing of various hard and brittle materials such as gold ore, concrete aggregate, asphalt aggregate, etc., the rod mill can save energy by 50% compared with the traditional sand making machine. It is currently the most advanced sand making equipment in the world.

ADVANTAGES

Save energy

40% less power than traditional models, and improved operating efficiency

Automation

Low energy consumption in production reduces cost input in production.

Adjustable output fineness

The discharge granularity can be changed, the built-in fineness control device, and the discharge can be equipped with a screening device.

Wide range of applications

It adopts advanced controllable feeding and discharging materials, which is suitable for ores with different hardness.

WORKING PRINCIPLE

The rod mill type sand making machine is driven by the motor through the reducer and the surrounding large gears or the low-speed synchronous motor directly through the surrounding large gears to drive the cylinder to rotate. The barrel is fitted with suitable steel rods. Under the action of centrifugal force and frictional force, the steel rod is lifted to a certain height and falls in the state of throwing or falling. The material to be ground enters the cylinder continuously from the feed port, is crushed by the moving steel rod, and the powder is discharged through the discharge grate to complete the sand making operation.
