Description

The vertical roller grinder of micropowders

The utility model relates to vertical roller grinder, refers in particular to a kind of finished product and exempts from through other classification, can once make the roller grinder structure of micropowders in machine.

Existing advanced fine powder is made machinery, with the rotary cup pulverizer is representative, its structure all includes a vertical machine trunk that is composed in series by majority, one vertically is located at the main shaft in the machine trunk, one is located at the suction dust feeder in the machine trunk of top, one is located at the separator of inhaling the dust feeder below, one is located at the muller device under the separator, reach a deceleration device with motor drive grinding, only its structure has following shortcoming: (1) its separator is just patted the large-scale groups body that blade connects by several, parallel being located in the trunk, with the direct path of the passage in the trunk as thin choosing, cause that the powder that separation screening produced through separator still is that thickness mixes in the manufacturing process, can not meet the requirement of specific use ultrafine dust, therefore generally can only be made for the function of the most basic grounds travel essence, can't once make ultra-fine micro mist.(2) as making with extra care, its made powder still needs can tell through the secondary classifying equipoment again, its finished product powder need load to come and go at refining stage and transport automatically between pulverizer and secondary classifying equipoment, can't once reach, lose time and shipment and delivery cost, and the fineness of its most products only can belong to low-value product in 10000 squares of branch public affairs/below the gram, will eliminate gradually because of material is of poor quality with the development trend of additive.(3) with calcium carbonate be example, its fine particles not only can be improved rerum natura, and can significantly reduce cost because of the equivalent different main fillers that can be used as plastics, rubber, coating, building materials, papermaking, food, medicine, agricultural, feed etc. of fineness.The range of application that contains is too numerous to enumerate, and more and more wider trend is arranged, and fundamentally how being made into fine powder is a big key of applying, and by the product that existing structure is produced, can only be the low-grades fine powder at most.Very limited in the application.In addition, though existing ultra-fine levigation can be made by ball mill, only its operation is gone up needs to use high power consumption, does not therefore meet economic benefit, will also can slowly lose competitiveness.

It is a kind of without the secondary classification that the purpose of this utility model is to provide, and can once grind the vertical roller grinder of producing super fine.

For reaching above-mentioned purpose, the utility model mainly comprises main body, mill, motor, reductor, feed pipe, the tube cell of giving vent to anger, and is characterized in:

One enclosed three-dimensional main body, the top is provided with feed pipe, the tube cell of giving vent to anger, and the side is provided with more than one air induction conduit; Lid covers one and is penetrated in the bend pipe by straight tube above main body, makes charging form the tap that consubstantiality links to each other with discharging; Also sheathed feed back center material is bored below the body interior feed pipe, be provided with the feed back endless tube below the mill ring encloses, feed back endless tube end face connects air induction conduit, and the side is provided with the material toggling scraper plate under the mill side, to scrape the buildup in the feed back endless tube, make the feed back outlet under the ring; One is located at the mill of body interior below over against the charging outlet, and the mill downside links reductor by a CD-ROM drive motor; One group of above mill roller that sets with mill, each roller promotes a pressure arm by oil hydraulic cylinder and is operated, and is pressed against during start to roll on the mill face to move; One is located at the guide ring that the mill ring encloses, and for the air induction conduit air inlet, gas blows on down; One group of above sorting mechanism is located at the main body upper interior, every group of sorting mechanism is made up of the classifying turbine that motor drives, the classifying turbine rear end connects the tube cell of giving vent to anger, motor then is arranged on the outer support of main body, the axis of affixed classifying turbine is arranged in the axle sleeve by bearing, axle envelope, and an end of axis is provided with belt pulley, by motor with belt drives.

Above-mentioned sorting mechanism, visual micro mist fineness requirement is being interval with above the main body more than 3 groups at least, and best is the 3-6 group, and is that horizontal arrangement is around the upper strata that is located at main body, to horizontal rotational shaft.

The utility model has the advantages that: 1, tumbling mill of the present utility model top is provided with sorting mechanism, can be directly and milling production stably, its finished product reaches the fine powder degree, does not need to screen through the secondary classifying equipoment again.2, the super fine sorting mechanism is to be horizontally disposed with, and the difference that requires according to thin choosing is the best with equidistant intervals configuration 3-6 group.This effective configuration adds the action that utilizes barreling, air blowing and sorting mechanism to accomplish without any letup in main body, make the grainding capacity that the utlity model has micropowders, with calcium carbonate is example, the fine powder specific area value that institute's barreling goes out can reach between 10000-18000 square centimeter/gram, if handle through ultra-fine smart powder concentrator, can tell the top grade powder of 25000 square centimeters of fineness/gram easily.The utility model is if compare with the ball mill that can make with extra care micro mist equally, and overall work can be saved 50% electric power.
