Coal mill dynamic separator Which is better? Yancheng takeoff environmental technology

I. Overview TMD coal mill dynamic separator is mainly used for cement plant coal preparation (grinding) system grading equipment, FMD coal mill dynamic separator both coarse separator and separator functionally performance, to achieve the feed gas go the same way to go to achieve the purpose of simplifying the system. TMD coal mill dynamic separator swirl grading, grading inertia, centrifugal classification principles of learning science together to improve the particle distribution, improving the quality of pulverized coal. At the same classification efficiency than conventional high efficiency separator increased by 10%. Additional vortex adjusting means in the rotor. Avoid the vortex pressure drop, reducing wear and tear, while reducing power consumption. Second, the specifications and performance parameters Model capacity (t / h) air volume (m3 / h) Rotor speed (rpm) Motor power (kw) TMD350 10-14 21000-24000 200-500 15 TMD500 14-24 24000-36000 200- 400 18.5 TMD700 24-30 36000-48000 200-350 22 TMD1000 30-40 55000-70000 200-350 45 TMD1500 43-52 80000-110000 200-300 55 Note: 1, according to user needs, the actual configuration may be configured in the table slightly different. 2, a conventional pulley deceleration deceleration configured, users can request the use of Gearbox. 3, the conventional lubricating oil pump is configured to dry, according to user requirements with thin oil station. 4, the conventional configuration without the cyclone dust collector, according to user requirements with a cyclone dust collector. Third, the principle to the air by a coal mill with material from the lower part of the duct into the separator, after rectifying the cone along the outer annular passage between the cone and the cone slowdown rise, which by gravity meal Settlement realize the gravity slide along the outer cone meal close barrel sorting, gravity separation after air with material particles in the rotation around the role of diversion and the rotor, the rotor is formed between the guide blades and stable level vortex separator area. Vortex movement of dust particles in the same time by the action of gravity, wind and rotating centrifugal force, the fine particles of light is sucked into the rotor with the air flowing through the air duct into the interior behind the role of the finished powder dust collector is separated. Heavy particles then fall through the cone collection to receive meal barrel, return the mill and then grinding. Changing rotor speed can effectively regulate product fineness. Fourth, the main structure and technical characteristics 1, the main structure of TMD coal mill dynamic separator, turning part, which mainly consists of driving part, part, lubrication systems and electronic control portion of the housing. (1) constituted by a driving section driving section driving motor and reduction gear. The driving portion is generally vertical motor with pulley deceleration devices, according to user requirements can be horizontal orthogonal axis motor plus reduction gear box. Motor Y series motor is changed by the current frequency AC drive motor, the motor speed change greater range. (2) the return part of the return part is separated from the core grade separator separator, which is composed of the main shaft and the rotor, after the slowdown driven by a motor. Spindle mounted on the hub sleeve, the upper hub sleeve mounted vertically on the bracket, the lower part of the rotor is coupled. To ensure the hub sleeve bearings have sufficient profits and prevent gray material into the ends of the sleeve has a dust-proof, anti-spill lip seals. The outer surface of the hub sleeve stick with wear-resistant ceramic, anti-wear on the outer surface of the receiving stream. The rotor has upper, middle and lower three separator plate with sealing ring, rotor blades welded between the upper and lower plates, evenly distributed along the circumference of the rotor is installed inside the vortex break up the vortex air after sorting rectification, reducing wear and tear on the air duct. To ensure the smooth working of the rotor body from "Shen one gram" electronic balancing machines for a delicate balance. Hub sleeve is equipped with temperature measurement devices to monitor the bearing temperature. (3) the housing portion of the case is the separator main load-bearing parts and the gas flow path, mainly sheet metal weldment. To facilitate the observation and maintenance, provided with a plurality individual holes on the housing. Installed inside the housing gap is even guide blades, steering flow to form a stable horizontal vortex strength Yang. In the guide blades of the inner ring with blocking plate and seal groove. To reduce airflow wear, guide blades, wear the cone so after technical treatment. (4) lubrication system TMD coal mill dynamic separator main bearing with dual dry pumps filling disulfide lithium grease lubrication, according to user requirements can be thin oil lubrication. As with oil lubrication is recommended when using N-68 anti-wear hydraulic oil, supporting the selection of XYZ series of thin oil station. Reduction gear box with LSOVg320 mineral oil. (5) Main cabinet AC drive by the main cabinet, bearing temperature meter and indicator lights. User-supplied inverter can also be supplied by the company, the central control room may be performed remotely through the cabinet. When the bearing temperature exceeds the limit temperature, so shiny lights, running lights off, a host stops running, when the oil station malfunction, can cause a host stops running. 2, the technical characteristics of our company on the basis of drawing the most advanced separator technology, the use of aviation aerodynamics analysis of TMD coal mill dynamic separator structure was further optimized parameters, I produced the coal mill TMD Separator reasonable internal structure management, higher separator efficiency, energy saving effect is more obvious. It mainly has the following characteristics: (1) production, working conditions TMD system wide configuration coal mill coal mill dynamic separator of 10-20% compared to configure a static separator system of coal mill output, advanced and reasonable separator structure allows air flow, changes in the larger scope of production without affecting the powder efficiency, its classification performance is very stable. TMD coal mill dynamic separator by air aerodynamic analysis of the entire flow field optimization design, making the device significantly reduced resistance and higher efficiency separator drive motor power consumption is greatly reduced, energy saving effect very obvious. Separator rotor built with vortex break, a gas flow within the rotor relative to the rotor is not rotating only rise, due to the use of rotational moment of momentum after the airflow is reduced impetus to the rotor drive power savings and reduce wear, many users feedback It shows that more than using my company's TMD coal mill dynamic separator 30-40% energy savings, users benefited. (3) simple operation, easy to adjust fineness TMD coal mill dynamic separator main motor remote control, easy to operate. By changing the separator main drive motor speed can be adjusted by the fineness of the product in a wide range. (4) wear a small, low maintenance costs TMD coal mill dynamic separator is easy to wear as part of the cone, hub sets, guide vanes and rotor blades etc. with wear-resistant material handling or abrasion process, the wear rate is very small, so its very low maintenance costs.
