Description
|
The ring die and also the pressing roller of the biomass pellet making equipment turn at a constant speed, and the functioning state of each immediate is basically the exact same. If the quantity of feed material is the same, the energy consumption should likewise be relatively steady, and the existing will be reflected on the motor. Also fairly secure.
When the biomass pellet making maker device is functioning, we adjust the feeding quantity as long as the material thickness in the feeding location is less than the maximum starting point of journalism location, it will straight affect the size of the effective working area of the pressing area and also journalism location, as well as create the existing to stream.
The change as well as the modification of the per hour result of the biomass pellet making device, and if the thickness of the product layer in the feeding area is higher than the optimum beginning point of journalism area, in addition to raising the density of the product layer in the feeding location, it will certainly not influence the hourly result and power usage per unit time.
If there is any impact, it will certainly no more create modifications in current as well as biomass pellet making maker outcome. Because the thickness of the material layer in the feeding area exceeds the optimum starting factor of journalism zone, the period between the pressing zone as well as the pressing area is constant without any change. In the interval where the multi-feed material is located, the securing angle is higher than the vital rubbing angle, and also the material will certainly not be squeezed into journalism area.
By doing this, with the increase of the feeding quantity of the biomass pellet making device, the balance of in and out is broken, and the in is above the out, and also the material layer in the feeding area is It will certainly collect thicker and thicker till all the voids are loaded as well as obstructed to the feed port, to ensure that the biomass pellet equipment can not work generally. Right now, the current will certainly boost.
In the actual job of the biomass pellet making equipment, with the change of the feeding quantity, the instant result as well as the current of the major electric motor will transform appropriately. As well as when the feeding thickness does not exceed the maximum starting point of journalism location, it will not trigger more and more worldly layers in the feeding location as a result of the boost in the quantity of powder we feed.
As has actually been said prior to, the location that can cause instant outcome and also energy intake changes should be the two locations of work and also material layers - the compression area and also the biomass pellet equipment extrusion location, so we assume that the 3rd area discussed over- - The practical presence of the feeding location has certain conditions.
That is to state, the fed product layer is distributed in the compaction location, the extrusion area and the feeding area whose total density does not go beyond the optimum access point of the compaction location.
The biomass pellet making device will certainly function normally under the allowed power. If the quantity is also huge and goes beyond the density of the optimum starting factor of the compaction area, the material layer will build up and also gradually rise, as well as the biomass pellet making device will certainly not work normally. Existing is changing.
With the above evaluation, allow's review some phenomena showed by the biomass pellet making maker under two feasible working conditions:
( 1 )When the power of the main motor is not large sufficient compared with the matching biomass pellet making machine granulation criteria, the thickness of our feed is at completion of the extrusion zone as well as the maximum entry factor of the compression zone (this will vary with the raw materials, compression ratio, efficient length-diameter proportion, moisture, stress rollers and other variable factors to change appropriately), normally will not go beyond the maximum starting factor, with the boost of the feeding quantity, the compression location will certainly alter as necessary.
The size of the interval will be reduced, and the interval length of the press area will slowly boost as necessary, and the current of the main electric motor will certainly likewise slowly boost until it reaches the maximum allowed usage. If the current reaches the security worth we set, as well as the thickness of the feeding product has actually not exceeded the thickness of the maximum starting factor of the biomass pellet machine pressing area, if the feeding quantity is increased, the safety system will act, and the excess powder will be discharged. In order to guarantee the regular feature of biomass pellets.
( 2 ) Intend the power of the primary motor is very large or the electric motor falls short to overload after the thickness of the feeding material surpasses the thickness of the optimum starting point of the pressing area because of the comprehensive adjustments of several variables. Currently, the powder fed to the people can not increase the moment result, neither will it create the increase of the main motor current, but can just remain to boost the powder pile gathered in the equipment until the internal cavity of the biomass pellet press device is blocked.
Create the biomass pellet making machine to not function properly. Obviously, this special phenomenon rarely occurs in real production (if the raw material moisture is as well big, the efficient facet ratio is too tiny, the pressure roller is seriously used and the void is not readjusted correctly, the raw product is replaced, etc, this phenomenon might take place), this is our unwanted conditions.
Extensive analysis of the first generally used working state, it is not difficult to understand that on the facility that the appropriate conditions are the same, with the adjustment of the feeding amount, the interval size of the compression zone as well as the extrusion zone is within a certain range Matching changes are likewise made (the feed flow rate is minimized, the size of the extrusion area is minimized, and also the size of the compression area is lengthened; or else, the extrusion zone is extended and also the compression zone is reduced), and also the feeding amount does not exceed the pressure. When the thickness of the optimum 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.
