Abstract
The present invention relates to a roller type mill with medium speed used for the electric power plant, metallurgy, chemical industry and cement powder making filed. The working principle is that: the milling bowl and the impeller device are rotated in a clockwise manner under the driving of the reducer, and the material falls to the milling bowl by the central falling coal tube, and then moves towards outside along the radial direction under the action of the centrifugal force, and a layer of material bed is formed on the milling bowl, and the material bed is through under the milling roller equipment which can rotate around the shaft. At this time, the milling force produced by the loading unit is pressed on the material by the rotating milling roller. The material is milled to the powder between the milling bowl liner and the milling roller. The material moving in a radial and surround manner carries the powder to pass the edge of the milling bowl to enter the transmission medium channel. The invention is of a novel and scientific design, which adopts hydraulic pressure turning to loading protecting the material with strong adaptability. The milling roller adopts the cone shaped roller shape, and using the special tool directly to turn the outside of the machine body for exchanging the milling roller sleeve, the milling roller bearing and the milling roller oil seal. Exchanging and overhauling the milling bowl liner is convenient, and the inner installing type coal powder separator structure is improved to the hopper shape, and the service life of the coal powder separator is prolonged, and the invention reduces the height of the milling machine and weight as well as the total investment of the project.
Description
Technical field:
The present invention relates to a kind of roll-type middling speed grinding machine in power station, metallurgy, chemical industry, the cement powder process industry.
Background technology:
At present, both at home and abroad medium-speed pulverizer has several major types, and MPS, ZGM, MPS-HP-II, RP, HP type are arranged, and wherein MPS, ZGM, MPS-HP-II type grinding machine are that German BABCOCK company art designs makes, grinding roller is a rubber-tyred, and load mode adopts hydraulic loaded; RP, HP type grinding machine are the manufacturings of U.S. ALSTOM company art designs, and grinding roller is a tapered roller, and load mode RP type hydraulic loaded, HP type are that spring becomes loading.MPS, ZGM, MPS-HP-II type medium-speed pulverizer are better to the adaptability of material, but volume is big, and maintenance workload is big, and the cost of investment height; RP, HP type medium-speed pulverizer volume are little, and maintenance is inconvenient, but the consumable accessory life-span is short, and be poor to the adaptability of the material of milling.Therefore, develop a kind of roll-type middling speed grinding machine is home and abroad new problem anxious to be solved always.
Summary of the invention:
The purpose of this invention is to provide a kind of novel science, adopting hydraulic pressure to become and loading keeps material adaptability strong, grinding roller adopts the tapered roller shape, the service life that major diameter slow-speed of revolution technology improves grinding roller, utilize specific purpose tool directly in body, to rout up and change the grinding roller roller shell outside the body, the grinding roller bearing, the grinding roller oil sealing, it is convenient to change the maintenance of mill bowl liner plate, the inner cone material adopts wear-resisting steel plate, increase the service life, save cost, built-in pulverized coal distributor architecture advances funneling shape, reduce exit velocity, prolong pulverized coal distributor service life, reduce the grinding machine height, reduce grinding machine weight, reduce total investment of engineering roll-type middling speed grinding machine.
The object of the present invention is achieved like this: a kind of roll-type middling speed grinding machine, operation principle is, mill bowl and impeller unit turn clockwise under the driving of reduction box, after material falls on the mill bowl by the center coal spout, radial outward moves in the action of centrifugal force lower edge, form a layered material bed on the mill bowl, the material bed passes through under the Burnisher apparatus that can rotate around the axis; At this moment, the power of milling that charger produces is applied on the material by the grinding roller that rotates, material is milled into powder between mill bowl liner plate and grinding roller, do radially and the material that circumferentially moves is carrying the powder that is broken and crosses the mill bowl edge and enter the pumped (conveying) medium passage, pumped (conveying) medium, be typically hot-air, mainly contain three effects: the one, it separates powder for necessary power is provided in the grinding machine; The 2nd, hot-air constantly makes coal be easy to mill to its drying in the mill processes of material; The 3rd, it is bearing the responsibility of carrying powder; In the mill processes of material, less lighter material particles is blown afloat from the mill bowl by the gaseous conveying medium hot-air continuously, carry air to be supplied with by primary air fan that is positioned at the grinding machine upstream or the independently mill exhauster that is positioned at the grinding machine downstream, primary air fan provides malleation, and mill exhauster provides negative pressure;
