The main body of the rod mill is a low-speed rotating cylinder horizontally mounted on two large bearings. The rod mill is driven by the motor through the reducer and the surrounding large gears, or by the low-speed synchronous motor directly through the surrounding large gears to drive the rotary part to rotate. Steel rods are installed inside the cylinder as grinding media. Under the action of friction force, it is lifted to a certain height, and it falls down in a state of throwing or leaking. The ground material continuously enters the inside of the cylinder through the feeding port, is crushed by the moving grinding medium, and is discharged out of the machine through the force of overflow and continuous feeding for the next stage of processing.
Rod mill is an effective, practical and reliable stone crushing machine. It is one of the sand and gravel equipment widely used in the sand and gravel industry for construction sand. It is mainly used for the processing and crushing of feldspar, quartz, ores and other raw materials. It is suitable for the production of abrasives, refractory materials, cement, steel sand, slag powder, copper ore, iron ore, gold ore, concrete aggregate, asphalt aggregate and other hard and brittle materials. The high-efficiency and energy-saving crushed stone sand making equipment can save 50% energy compared with the traditional sand making machine.
