Amount utilizes the kiln tail gas of preheater kiln, and saves energy consumption, and mill efficiency is high, compared with milling system, has floor space
Small, process system is simple, capital expenditure save, low energy consumption, and metal consumption is few, low noise, either system or single machine relative to
Weight is all small for ball mill, can save a large amount of metal material.
Roller type vertical mill is widely used at home, in outer manufacture of cement in recent years, domestic at present all to be adopted there are many producer
With roller type vertical mill come materials such as pulverizing cement raw material, raw coal, clinker and slags, and adequately affirmed.Roll-type is vertical
Mill is a kind of material bed extruding disintegrating apparatus, and mill makes it be revolved around center by retarder by motor or hydraulic motor to drive
Turn, is fed to after the central point of mill by drawing-in device by the material of grinding and spins wire type movement outward with the mill being rotating
Diffusion is spread out, and is pressed from hydraulic loading system driving grinding roller to the material of mill disk, so that material is extruded, crushed, pass
The roller type vertical mill of system be typically organism bottom connection air-heater, the material of crushing is blown afloat, the powder concentrator structure through organism bottom and
Air-introduced machine is attracted to engine body exterior collection, but the external mode attracted is less efficient, and attraction power is to be improved.
Invention content
The purpose of this utility model be to provide for a kind of structure design it is more reasonable, using energy saving reliable vertical roller grinder
Machine fundamentally solves the problems, such as that external suction powder existing for conventional roller-type Vertical Mill is less efficient.
The technical solution of the utility model is：
A kind of vertical roll grinder, including body, in body the mill of bottom, surround the equally distributed multiple mills of mill
Roller, the powder concentrator structure being built at the top of body, the underpart are equipped with the hot-wind inlet being connected with air-heater, and feature exists
In：The body top center is provided with the support base of bearing, at the top of the body using support base be supported by axial line with
The upper port outside of the vertical feed pipe that the center line of mill overlaps, the vertical feed pipe utilizes transmission mechanism and driving motor
It is connected, the vertical feed pipe is stretched into mill top in body, and the powder concentrator structure is by being fixed in the middle part of vertical feed pipe
Select powder rotor, set on select powder rotor outer periphery helical blade, set on select powder rotor bottom cone-shaped collection bucket, be set to cone-shaped collection
Struggle against the refeed line composition of bottom, and the cone-shaped collection bucket and refeed line are enclosed on the outside of vertical feed pipe, the refeed line and
Returning charge channel is formed between vertical feed pipe, it is described to select powder rotor that internal body is separated into epicoele and cavity of resorption, it is described that powder is selected to turn
Sealing ring is equipped between sub- upper surface and the lower face of epicoele, the top side of the epicoele is equipped with powder outlet.
The utility model has the beneficial effects that：
1, helical blade is set on the outside of powder rotor due to selecting, in rotation process, helical blade generates upward attraction naturally, matches
Conjunction air-heater work suction effect is preferable, and grinding efficiency is higher.
2, the mode of top center charging ensure that charging is uniform, prevent grinding machine from vibrating.
3, returning charge channel is formed between refeed line and vertical feed pipe, realizes that regrinding provides channel, structure for coarse powder
It is ingenious in design.
4, entire machine is compact-sized, and production efficiency is high.
