Wood powder machine dust collector function:


Kefan wood powder making machine dust collector have many kinds model, generally we equipped round anto-pressure dust collector, pulse bag dust collector, bag dust collector. The bag dust collector equipped on the wood powder machine main function: filtration and dust cleaning two side. Dust collecting can clean all the materials like saw dust in the wood flour machine.
According to bag dust collector existing technology standard, making sure filtration effect achieve national standard isn't a difficult thing. But control wood powder machine bag dust collector equipment resistance at limited range is much more difficult. Make a general survey of bag dust collecting system appear working with bad effect problem, it has many relative about dust collecting with bad effect, so, clean dust is the determined factor relative to whether bag dust collecting system success or failure.
As wood powder making machine output products is powder condition, these powder is too fine, big adhesion and is difficult to clean. So, we suggestion that: after wood powder machine stop working, you can put bag dust collector to blow-off nozzle blowing, it sounds difficult but easy in fact. Or you can put the dust collecting device to water to soak, these powder will normal deposition and can be completely discharging.

Wood chipper application,feature and working tips:


The wood chipping machine main composed by swarf device, grinding device and blower. Wood material through swarf device, output products with small size granule, no need dry up and can feeding to grinding device to carry out futher grinding. Grinded wood dust products conveying to aggregate site by blower. The best wood chipper price whole equipment only need a motor to drive, simple structure, compact layout, best price, stable working, low energy consumption, high production capacity, good wood dust products, low investment. Can process bamboo, twitch-grass, cornstalk, sorghum stalk and other fiber stalk material. The machine can also process chipboard, saw dust board high density board raw material.
Wood chipping machine is according to our national industrial production requirement, through many years research developed wood material grinding series special equipment. As compact design and structure, safety, durable, high production efficiency, after popularize and using, with good effect, low noise, etc.
Wood chipper working principle:
Wood chipper for sale adopt blade cutting and high speed gas impact, collision dual crushing function in one and also can finish micro-material separating and processing. During blade cutting and crushing process, rotor produce high speed gas, rotation along with blade cutting direction, material increase working speed in gas and repeat impact material and suffering dual crushing, speed up material grinding rate.

High pressure suspension mill structure and working principle:


High pressure suspension mill working principle:
Inner high pressure suspension grinding mill, grinding roller hanger fixed 1000-1500kgs high pressure spring pressure. After start working, grinding roller rotation embrace around main shaft and under high pressure spring and centrifugal force function, roller cling grinding ring, under the same power condition, rolling pressure compared with raymond mill higher 1.2times. So, it's working capacity is improved greatly. After grinded material flow into grinding chamber, feed between grinding roller and grinding ring to press by blade. After grinded, powder along with blower recirculating air flow into analyzer. Qualified fine powder along with airflow to cyclone powder collector and get final products, big size granule re-falling to grinding chamber to grind. Recirculating air return blower repeat above process, remaining wind will flow to bag dust collector to purification. After high pressure suspension grinding mill grinding roller and grinding ring achieve a certain abrassion, adjust high pressure spring length, keep grinding roller and grinding ring constant pressure to make sure stable production capacity and fineness.
High pressure suspension mill structure introduction:
High pressure suspension grinding mill composed by main host, fineness analyzer, blower, final products cyclone powder collector, bag dust collector and airflow pipeline connection, etc. According to clients needs, it can equip crusher, elevator, silo, electric-vibration feeder and power distribution cabinet, etc. In the main host, grinding roller subassembly through cross arm shaft suspension on the grinding hanger, grinding roller hanger and main shaft blade frame keep fix connection, pressure spring outward grinding roller bearing chamber cantilever, put cross arm shaft as supporting point compel grinding roller tightenly press on grinding ring surface, when motor through driving device drive main shaft rotation, blade and grinding roller synchronous revolution, at the same time, grinding roller in grinding ring revolve on its axis. High pressure roller mill motor through driving device drive analyzer impeller rotation, the more the impeller rotation speed, the finer the separated powder.

How to improve raymond mill powder discharging capacity:


Raymond grinding mill is nowadays the most common industrial one of powder making equipment. The machine discharging capacity directly effect the whole project efficiency, you can find raymond mill production efficiency effects, for improve powder discharging capacity and each enterprise is very important, thus, henan kefan engineer summarizes the following tips to discuss;
Effect raymond mill discharging capacity factors:
Material too hard; harder material using raymond roller mill to grind is more difficult, and is more serious to abrassion the equipment, the machine working with slow speed, of course, with small capacity.
Material moisture: when material with big moisture, material is easy adhere to the raymond mill and easy to be blocked during discharging process, lead to working capacity reduced.
Raymond grinding mill output products fineness: high fineness requirement, the required raymond mill output material finer, the smaller working capacity.
Material compose: before grinding, more finer powder will have bigger effect on raymond mill, as these fine powder will easy adhere to conveying. For raw material with too much fine powder, you should screening once time before feeding to the machine.
Material viscosity: material with bigger viscosity will easy adhere to the machine.
Raymond mill spare parts(hammerhead, jaw board) with good wearable properties, the machine working with bigger capacity, if the spare parts is easy abrassion will effect working capacity.
Solve methods:
1. Raymond roller mill forward add fine crusher;
2. Improve powder grinding system, improve powder grinding effect;
3. Add high efficiency powder separator;
4. Check and adjust powder locker sealings, replace new blade;
5. After clean the airflow pipeline material, re-discharging again.
