A rod mill is a mill in which the grinding body is a steel rod. The rod mill is generally a wet overflow type, which can be used as a first-stage open-circuit grinding. It is widely used in the first-grade grinding of artificial stone sand, concentrating plants and chemical power plants.
Application
Iron ore, steel slag, quartz, tungsten tin, dolomite, coal water slurry, copper ore, limestone, gold, manganese, bauxite, lead-zinc.
The rod mill is an asynchronous motor connected to the pinion through a reducer, which directly drives the peripheral large gear to decelerate and rotate, and drives the rotary part to rotate. The inside of the cylinder is equipped with a suitable grinding medium - steel rod, grinding medium in centrifugal force and friction Under the action of the material, the material to be ground continuously enters the inside of the cylinder from the feeding part, is crushed by the moving grinding medium, and discharges the product out of the machine by the force of overflow and continuous feeding to carry out the next process.
Technical characteristics
▲ The transmission type of the barrel mill has the following types: edge leaflet, center drive, multi-point meshing edge drive, etc. The drive type includes asynchronous motor + reducer + pinion + large gear and synchronous motor + air clutch + pinion + large gear;
▲ Generally adopt the support method of static pressure bearing at both ends, adopt fully enclosed self-aligning 1200 line contact 'rocker type' bearing, or use single sliding, double sliding static pressure support or full static Pressure support
▲ The large open gear is designed by American AGMA standard, equipped with a sealed and reliable gear cover, and equipped with glycerin automatic spray lubrication device;
▲ The cylinder is the key part of the mill, and it is finite element analysis by computer to ensure the reliability of its use;
▲ Large and medium-sized mills are equipped with slow drive devices;
▲ Large and medium-sized mills are equipped with high and low pressure lubrication stations;
▲ Control and protection system adopts PLC control;
