Unstable current of the biomass pellet making equipment
The ring die as well as journalism roller of the biomass pellet making maker rotate at a consistent rate, and also the working state of each immediate is generally the exact same. If the quantity of feed material is the same, the power consumption need to likewise be reasonably steady, and also the existing will certainly be reviewed the electric motor. Also relatively secure.
When the biomass pellet making machine equipment is working, we change the feeding quantity as long as the product thickness in the feeding area is less than the maximum starting point of the pressing area, it will directly affect the length of the efficient workplace of journalism location and the pressing location, and create the existing to stream.
The variation and the change of the hourly result of the biomass pellet making machine, and if the density of the product layer in the feeding location is above the optimum beginning factor of journalism area, in addition to increasing the thickness of the product layer in the feeding area, it will not impact the hourly result and also energy intake each time.
If there is any kind of influence, it will certainly no longer trigger adjustments in present as well as biomass pellet making maker output. Since the thickness of the product layer in the feeding zone surpasses the maximum beginning factor of the pressing zone, the interval between journalism area and journalism area is constant with no modification. In the interval where the multi-feed product lies, the securing angle is higher than the important friction angle, and the product will certainly not be pressed right into the pressing area.

By doing this, with the rise of the feeding amount of the biomass pellet making maker, the balance of in and out is damaged, and also the in is higher than the out, and the material layer in the feeding area is It will gather thicker and also thicker until all the voids are filled up and also obstructed to the feed port, to make sure that the biomass pellet equipment can not work typically. At this time, the current will enhance.
In the actual work of the biomass pellet making device, with the adjustment of the feeding quantity, the instantaneous result as well as the current of the major motor will transform appropriately. And when the feeding density does not go beyond the optimum starting point of the pressing location, it will certainly not trigger an increasing number of material layers in the feeding area because of the increase in the amount of powder we feed.
As has been claimed before, the location that can cause instant result and also power consumption modifications must be both locations of job and product layers - the compression area as well as the biomass pellet machine extrusion area, so we assume that the third location discussed over- - The reasonable presence of the feeding area has certain problems.

That is to claim, the fed product layer is dispersed in the compaction location, the extrusion area as well as the feeding area whose total thickness does not exceed the maximum entry point of the compaction location.
The biomass pellet making maker will certainly function generally under the permitted power. If the amount is as well huge and also exceeds the density of the maximum beginning factor of the compaction area, the material layer will gather and gradually increase, and also the biomass pellet making equipment will certainly not function usually. Existing is varying.
With the above analysis, allow's review some sensations showed by the biomass pellet making device under 2 feasible working problems:
( 1 )When the power of the major electric motor is not large sufficient compared with the equivalent biomass pellet making maker granulation specifications, the density of our feed is at completion of the extrusion zone and also the optimum entry factor of the compression area (this will vary with the raw products, compression ratio, reliable length-diameter ratio, moisture, pressure rollers and various other variable aspects to readjust accordingly), normally will not surpass the maximum beginning factor, with the rise of the feeding quantity, the compression location will transform appropriately.

The size of the period will certainly be shortened, and also the interval size of the capture location will gradually increase appropriately, and the current of the main motor will additionally progressively enhance till it reaches the maximum permitted usage. If the current reaches the defense worth we set, and the density of the feeding material has not surpassed the thickness of the maximum starting point of the biomass pellet equipment pressing location, if the feeding amount is increased, the safety and security system will act, and also the excess powder will be discharged. In order to ensure the regular function of biomass pellets.
( 2 ) Intend the power of the primary motor is large or the electric motor falls short to overload after the density of the feeding product goes beyond the thickness of the maximum beginning point of journalism location due to the thorough modifications of numerous variables. At this time, the powder fed to the people can not enhance the moment outcome, neither will it trigger the boost of the main motor existing, but can only continue to raise the powder pile built up in the machine till the internal cavity of the biomass pellet press device is blocked.
Trigger the biomass pellet making equipment to not work properly. Of course, this unique phenomenon rarely occurs in actual production (if the raw product moisture is too huge, the reliable element proportion is also tiny, the stress roller is seriously used and also the space is not readjusted properly, the raw product is changed, and so on, this sensation may happen), this is our unwanted conditions.

Extensive analysis of the initial frequently utilized working state, it is uncomplicated to understand that on the facility that the relevant problems are unmodified, with the adjustment of the feeding amount, the interval length of the compression zone and the extrusion area is within a certain variety Matching adjustments are likewise made (the feed circulation rate is minimized, the size of the extrusion area is lowered, and also the length of the compression zone is lengthened; or else, the extrusion area is expanded and the compression zone is shortened), and the feeding amount does not go beyond the stress. When the density of the maximum beginning point of the limited area is concerned, the lengths of the above two intervals are not a constant value when this article is written. The larger the extrusion zone length value, the higher the biomass pellet maker production efficiency and the longer the pellet length per extrusion per roller.
Therefore, it is concluded that the factors of current instability under the condition of controlling the feeding amount need to be investigated from the moisture content of the raw material, the effective aspect ratio is too small, the pressure roller is severely worn and the gap is not adjusted properly, and the raw materials are replaced.
