Roller mill operation principle be grinding roller under centrifugal action tightly roll extrusion on bull ring, scooping up material by perching knife delivers in the middle of grinding roller and bull ring, material is broken into powder under the effect of grinding pressure, then under the effect of blower fan, the material of one-tenth powder is blown afloat machine by analysis, the material reaching fineness requirement passes through analytical engine, the mill chamber of returning not reaching requirement continues grinding, enters whirlwind classifier separated and collected by the material of analytical engine.Air draft adopts industrial filter cloth isolation air draft once to become powder.This machine of the Raymond mill scope of application is mainly used in barite, calcite, potassic feldspar, lime stone, talcum, Bai Shi, gypsum etc.Mohs' hardness is not more than 9.3 grades, the mineral products that the non-flammable of humidity below 6% is explosive, the thin powder process processing of height of hundreds of material such as chemical industry, building material product, and product granularity is 40 ... regulate arbitrarily within the scope of 400 orders.These series of products are for different material, and different fineness, the requirements such as different output, are divided into high-pressure micronizer, suppress overhang roll mill, the large series of common Raymond mill three tens kinds of types.
The a whole set of structure of roller mill is made up of main frame, analytical engine (powder concentrator), plumbing installation, air blast, finished product cyclone separator, jaw crusher, bucket elevator, electro-vibrating feeder, electronically controlled motors etc.Wherein Raymond mill main frame is made up of frame, air intake spiral case, perching knife, grinding roller, bull ring, case and motor.
The a whole set of course of work (grinding material process) of roller mill: large-block material is crushed to after required granularity through jaw crusher, by elevator, material is delivered to storage bin hopper, send in mainframe grinding chamber continuously through oscillating feeder equal and quantitative and grind, the powder after grinding is taken away by fan airflow.Machine carries out classification by analysis, and the powder meeting fineness enters in willy-willy collector with air-flow through pipeline, carries out separated and collected, then is finished product powder through tube cell discharge.Air-flow sucks air blast by willy-willy collector upper end backwind tube again.The whole air flow system of the machine is sealing and circulating, and circulates under positive/negative-pressure state.
The dedusting method of existing roller mill is being blown afloat by material after roller mill after entering roller mill blower fan by natural wind, and then collect in cyclone dust collectors, and dust that is unnecessary or that do not collect is collected through secondary cyclone deduster.Its structure as shown in Figure 1, unnecessary dust entered secondary cyclone deduster when collecting, because original system only has a Fans to carry out power transmission, the too small words that blower fan leaves, material after pulverizing can not be collected, it is excessive that fan delivery is opened, and easily escapes out from places such as the bolted on part of machine and observation doors by material, cause very large dust pollution.
Summary of the invention
The object of the invention is to provide a kind of roller mill system reducing dust, solves the problem that existing roller mill system easily causes dust pollution.
Technical scheme of the present invention is: a kind of roller mill system reducing dust, comprise roller mill blower fan, main machine for roller mill, cyclone dust collectors, sack cleaner, bag-type dust blower fan, described roller mill blower fan, main machine for roller mill, cyclone collector, sack cleaner, bag-type dust blower fan connect in turn.
Further, described bag-type dust blower fan is negative pressure roots blower.
In the utility model, by the adjustment of the air quantity of roller mill blower fan, make the material entering main machine for roller mill just can enter in cyclone dust collectors fast after pulverizing, the material that granularity is less simultaneously can directly enter in sack cleaner, simultaneously by power that the negative pressure roots blower of sack cleaner provides, small grain size material can be made to precipitate in cloth bag, then collect at sack cleaner discharge port place, contrasted by practical operation, the material that the original whirly deduster of material ratio at sack cleaner discharge port place is collected reduces 1/3rd, simultaneously, large-area airborne dust situation is now stopped.
The present invention compared with prior art tool has the following advantages:
The invention solves airborne dust in puzzled roller mill powder process for a long time and effectively cannot carry out the problem processed, solve from root the condition that roller mill airborne dust produces, thus provide good environment for the working environment of workman.
Accompanying drawing explanation
Fig. 1 is roller mill system architecture schematic diagram of the prior art;
Fig. 2 is roller mill system architecture schematic diagram of the present utility model.
In figure, Reference numeral is: 1-roller mill blower fan, 2-main machine for roller mill, 3-cyclone dust collectors, 4-whirly deduster, 5-sack cleaner, 6 sack cleaner blower fans.
Detailed description of the invention
Embodiment
As shown in Figure 2, a kind of roller mill system reducing dust, comprise roller mill blower fan 1, main machine for roller mill 2, cyclone dust collectors 3, sack cleaner 5, bag-type dust blower fan 6, described roller mill blower fan 1, main machine for roller mill 2, cyclone collector 3, sack cleaner 5, bag-type dust blower fan 6 connect in turn.
Fig. 1 is the roller mill system of prior art, during medium and small cyclone dust collectors 4 collection material of this system, because the raw meal particle size collected of secondary gathering system is less and flow velocity fast, causes collecting effect good, easily forms the circulating collection of small grain size material.Now the secondary cyclone duster system of former roller mill system and whirly deduster 4 are carried out dismounting transformation, after transforming sack cleaner 5 as, Be very effective.Connect sack cleaner 5 from the wind pipe of cyclone dust collectors 3, sack cleaner 5 is outer with negative pressure roots blower, by regulating the size of roller mill blower fan 1 and sack cleaner blower fan 6 power, thus can balance and the generation reducing dust.
