How To Select Pellet Machine Mold Compression Ratio
Just How To Select Pellet Maker Mold Compression Ratio?

Prior to the pellet equipment mold is used, the compression ratio have to be adjusted and also determined. This is mostly to adjust the diameter of the mold, the thickness, the taper as well as reaming degree of the bell mouth, the product of the mold, the firmness of the mold, and various materials, there are various mold compression ratios.

So we have to adjust and also compute according to our real circumstance, so what is the modification estimation approach of the pellet equipment mold compression ratio?

Compression Ratio Of Pellet Machine Mold

The compression ratio of the pellet equipment die describes the ratio of the reliable size of the die opening of the die to the die size, and also is an index showing the extrusion toughness of the pellet maker.


Pellet maker mold compression ratio = mold hole diameter/ effective working size of mold opening

For a mold with a straight opening, the reliable length of the mold hole is the total thickness of the mold, and the tiny size is the diameter of the mold opening itself.

Presumption: The diameter of the die opening is 6mm, as well as the density of the ring die is 45mm

Compression ratio= 6/45= 1:7.5.

The ring mode compression ratio is 1:7.5.

For the release action opening and the external conical hole, the effective size of the die opening is the complete density of the mold minus the size of the release hole or the length of the outer tapered hole, and the aperture of the little size area is the aperture for calculating the compression ratio.

Assumption: the diameter of the ring die opening is 8mm, the die thickness is 66mm, and also the release hole is 18mm.

Compression ratio= 8/( 66-18)= 1:6.

The ring mode compression ratio is 1:6.

Compression ratio is a ratio. For small pellet mill price , its aperture and reliable functioning length may be various.

How To Pick a Suitable Mold Compression Ratio?

1. The aperture size as well as outcome of the mold are closely pertaining to the internal size of the pellet machine mold and also the make-up of the raw products. The common aperture of 8-10 mm usually utilized in the market is called standard information.

The pellet maker larger than 10 mm needs higher pressure for molding., Relatively speaking, the wear is likewise large, users generally call it a biomass rod making equipment or a pole making machine.

2. The efficient density of the mold is very vital for the molding of raw materials.

If the mold is as well thick, the molding time of the raw product is longer, the thickness of the fragments is relatively large, the extrusion is harder, the mold is slim as well as easy to damage, as well as the density of the particles is fairly little.

Journalism temperature level is reduced, the outcome is high, yet the molding price is reduced or the molding is poor.

3. The compression ratio of unpleasant tools is determined according to the raw products. The compression ratio of poplar wood is 1:6, the compression ratio of yearn wood is 1:7, the compression ratio of hard wood is 1:5, and also the compression ratio of shavings is 1.: 5.5, the compression ratio of corn stalk is 1:6.5.

From these straightforward numbers, the compression ratio of different raw materials is different. The tougher the raw product, the smaller sized the compression ratio, and also the cosy the raw product, the greater the compression ratio.

That is to say, the much more fluffy the raw product, the much easier it is to be built. The more cosy basic material has more fibers, and the even more fiber-containing materials are less complicated to form.

4. Each tiny hole straight has 6 mm, 8 mm, and also 10 mm. This 1 stands for the size of each little opening. If rice husk pellet machine of the ring die hole is 8 mm, then this 1 stands for 8, And 6 stands for the effective aperture.

The effective aperture amounts to the size of the hole multiplied by the reliable aperture length, which is 6 * 8= 48, which is 8:48, 8:48 is streamlined to 1:6, 1: 6 is the compression ratio of poplar wood. It is converted this way.

The top quality of the biomass pellet maker's outcome relies on the compression ratio of the ring die. But if the client does not have high requirements for the molding rate of your pellets, after that you can suitably Decrease the compression ratio, which can not only boost the outcome, however additionally lower the service life of the mold as well as journalism wheel.

5. Roughness is additionally a vital sign to determine the high quality of ring die. Under the very same compression ratio, the better the roughness worth, the greater the extrusion resistance of the sawdust fragments, and also the harder it is to release the material.

Extreme roughness additionally impacts the high quality of the bit surface area. The suitable roughness worth should be 0.8-1.6. between.

What To Do If animal feed making machine price Is Also Huge.

1. Experienced operators will readjust the dampness material of the raw materials or change the space between the ring molding rollers, as well as the pellets can be efficiently released without transforming the compression ratio. The process needs to be videotaped as well as checked detailed.
2.
2. In addition, the 2nd pressurization can make the mold with a larger compression ratio smaller, however modifying the ring mold will influence the firmness of the ring mold, so it needs to be determined according to the real wear of the mold.

The roughness of the die opening of the pellet maker is likewise an important indicator to gauge the top quality of the mold, as well as the proper roughness worth must be between 0.8-1.6.


Under the exact same compression ratio, the bigger the roughness value, the better the bit extrusion resistance, as well as the more difficult it is to release the material. Excessive roughness likewise affects the top quality of the fragment surface.
