Definitions
- the invention relates to a material bed grinding equipment, in particular to an external circulation roller type vertical mill.
- the equipment for these grinding operations is the grinding equipment.
- common grinding equipments include tube mills, roller presses and roller vertical mills. Because the roller press and the roller vertical mill belong to the material layer grinding equipment, their grinding efficiency is higher than that of the tube mill, so they have reached a wide range of applications in the grinding operation.
- Roller vertical mill is a kind of grinding machine that uses the principle of material layer grinding to grind materials. It has been widely used in cement, coal, electric power, metallurgy, mineral processing and other industries. At present, the common vertical mill is a full-air-swept mill. The material is crushed by the relative movement of the grinding roller and the grinding disc, and the ground material is dried by hot air and carried upward into the powder concentrator. It is classified in the mill, and the coarse powder falls on the grinding disc to be smashed again; the finished product is sent out of the mill by air flow and collected by the dust collector. Specific process: After the material is squeezed, as the grinding disc rotates, the material falls from the edge of the grinding disc to the nozzle ring under the action of centrifugal force.
- the high-speed swirling wind blows and blows away, and the metal and heavy ore will settle. Discharge under the spout ring.
- the fine powder is brought to the upper part of the vertical mill and is sorted by the powder separator.
- the finished product enters the dust collector along with the gas and is collected.
- the sorted coarse particles fall into the grinding disc and grind again, and the high-speed swirling wind at the nozzle ring throws those coarse particles up, and as the wind speed decreases during the ascent process, they gradually lose support and settle on the grinding disc. , Relying on centrifugal force to enter the rolling area of the grinding roller and the grinding disc again for rolling and grinding.
- heat transfer between the particles and the gas causes the moisture to evaporate.
- the vertical mill is composed of six parts: the casing and the base, the grinding roller and the grinding disc, the pressure device, the grading device, the transmission device and the lubrication system.
- Roller type vertical mill is a kind of full air swept mill.
- the material ground between the grinding roller and the grinding disc is blown and dispersed by high-speed gas at the nozzle ring, and then lifted upwards.
- the coarser particles are When it is lifted and blown upwards, due to its gravity, it is affected by the bottom-up high-speed airflow during the falling process.
- Some materials are always in a suspended state, and some materials fall onto the grinding disc during the lifting process, and then fall from the edge of the grinding disc.
- the airflow at the nozzle ring blows up, so a large amount of internal circulation is formed, which causes the internal dust concentration to be too high, which will cause the airflow resistance to move upwards.
- the wind speed at the nozzle ring is higher, and its resistance is also Higher, the overall pressure difference of the vertical mill is generally higher, generally between 7000-10000Pa.
- the use of air force to bring a large amount of materials from the bottom up requires a lot of energy consumption, which directly increases the energy consumption. The rise.
- the finer materials in the mill are brought up by the gas and enter the classifier for classification.
- the coarser powders that are separated fall into the inner ash hopper and enter the grinding disc for re-grinding.
