Description
Technical field
The utility model relates to a kind of Raymond machine.
Background technology
Raymond machine is abrasive dust equipment commonly used, and applicable various breeze preparations, pulverized coal preparation, such as the fine powder processing of the materials such as raw material ore deposit, Gypsum Mine, coal.This owner of the Raymond mill scope of application will be for barite, calcite, potassic feldspar, lime stone, talcum, Bai Shi, gypsum etc.Mohs' hardness is not more than 9.3 grades, and humidity is at the non-inflammable and explosive mineral products below 6%, and the thin powder process of the height of hundreds of materials such as chemical industry, building material product is processed, and product granularity is 40 ... in 400 order scopes, regulate arbitrarily.These series of products are for different material, different fineness, and the requirements such as different output, be divided into high-pressure micronizer, suppresses overhang roll mill, tens kinds of types of common Raymond mill three large series.
At present, the operation principle of the illiteracy mill of existing Raymond machine is: crush roller under centrifugal action tightly roll extrusion on bull ring 2, on the circumference of bull ring 2, be evenly equipped with perching knife, by perching knife, scoop up material and deliver to grinding roller and bull ring 2 centres, material is broken into powder under the effect of grinding pressure, then the material that becomes powder is blown afloat through powder concentrator 7 under the effect of air blast 15, reach the material of fineness requirement by powder concentrator 7, the interior continuation in mill chamber 4 of returning that does not reach requirement is ground, and the material by powder concentrator 7 advances whirlwind classifier 8 separated and collected.
Raymond grinding powder grind materials process: large-block material is after jaw crusher is crushed to required granularity, by elevator, material is delivered to storage bin hopper 6, in the oscillating feeder equal and quantitative is sent into mainframe grinding chamber 4 continuously, grind, the powder after grinding is taken away by the air-flow of air blast 15 again.Through powder concentrator 7, carry out classification, the powder that meets fineness in pipeline enters willy-willy collector 8, carries out separated and collected with air-flow, then discharges and be the finished product powder through tube cell.Air-flow sucks air blast 15 by willy-willy collector upper end backwind tube again.The whole air flow system of the machine is sealing and circulating, and circulates under the positive/negative-pressure state.
The material that hardness is larger that mostly is due to the Raymond machine pulverizing, so in use need a large amount of electric energy of loss, as shown in Figure 3, the illiteracy of Raymond machine mill comprises two cover crush rollers at present, two cover crush rollers are rotatably installed on upper backup pad 23, upper backup pad 23De center is equipped with power transmission shaft 21, the lower end of power transmission shaft 21 is provided with lower supporting plate 24, power transmission shaft 21 drives upper backup pad 23 and rotates, two cover crush rollers rotate around power transmission shaft 21, self also under the effect of frictional force, rotate simultaneously, for better pulverizing, levigate material, the material of the larger grinding of diameter that experimental results show that ball milling 20 is thinner, quality is better, and ball milling 20 is larger, after rotating, inertia is larger, more power saving, but because the size of mill chamber 4 is certain, and power transmission shaft 21 also has certain diameter, thereby the diameter that increases ball milling 20 is just very difficult, can only increase by the diameter that chamber 4 is ground in increase the diameter of ball milling 20, but the method for this increase ball milling 20 diameters makes the size increased limited, effect is also not obvious.
In addition, Raymond machine in use, the electric energy that air blast 15 consumes is also very large, as shown in Figure 4, the air channel of traditional air blast 15 is in bull ring 2, after material enters mill chamber 4, wind passage mouth can be blocked, air blast 15 wind-force that needs are very large could blow material open, simultaneously levigate material is blown afloat, and this process need expends a large amount of electric energy could be realized.
Existing Raymond machine exhaust emissions does not generally have purifier, and tail gas contains the band dust and enters in the lump in air, has caused air pollution.
