How To Select Pellet Machine Mold Compression Ratio
How To Pick Pellet Machine Mold Compression Ratio?

Before the pellet maker mold is utilized, the compression ratio have to be changed and calculated. This is generally to adjust the size of the mold, the thickness, the taper and reaming level of the bell mouth, the product of the mold, the solidity of the mold, as well as different materials, there are various mold compression ratios.

So we need to adjust and determine according to our actual circumstance, so what is the change estimation technique of the pellet maker mold compression ratio?

Compression Ratio Of Pellet Maker Mold

The compression ratio of the pellet maker die describes the ratio of the reliable size of the die hole of the die to the die size, as well as is an index reflecting the extrusion toughness of the pellet maker.

Pellet maker mold compression ratio = mold hole diameter/ reliable working length of mold opening

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

Assumption: The diameter of the die opening is 6mm, as well as the thickness 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 as well as the outer tapered hole, the effective size of the die hole is the overall thickness of the mold minus the length of the release hole or the size of the outer conical opening, and also the aperture of the tiny diameter section is the aperture for determining the compression ratio.

Assumption: the diameter of the ring die hole is 8mm, the die density 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 the exact same compression ratio, its aperture and efficient functioning size might be various.

Just how To Choose an Ideal Mold Compression Ratio?

1. The aperture size as well as outcome of the mold are carefully related to the inner diameter of the pellet equipment mold and the make-up of the raw products. The typical aperture of 8-10 mm generally used in the industry is called standard information.

The pellet machine larger than 10 mm requires higher pressure for molding., Reasonably talking, the wear is likewise large, customers typically call it a biomass pole making machine or a rod making machine.

2. The efficient density of the mold is very crucial for the molding of resources.

If the mold is too thick, the molding time of the raw material is much longer, the thickness of the particles is reasonably large, the extrusion is more difficult, the mold is slim as well as very easy to break, and also the thickness of the fragments is relatively tiny.

The pressing temperature level is low, the outcome is high, however the molding rate is reduced or the molding is poor.

3. feed pellet machine of abrasive tools is established 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 simple figures, the compression ratio of different raw materials is different. The more challenging the raw product, the smaller the compression ratio, as well as the cosy the raw material, the better the compression ratio.

That is to claim, the more cosy the raw material, the simpler it is to be molded. The more fluffy basic material consists of much more fibers, and the more fiber-containing products are much easier to form.

4. Each tiny hole straight has 6 mm, 8 mm, as well as 10 mm. This 1 stands for the size of each small hole. If the diameter of the ring die opening is 8 mm, then this 1 represents 8, As well as 6 stands for the efficient aperture.

The effective aperture is equal to the diameter 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 transformed by doing this.

The high quality of the biomass pellet equipment's result depends upon the compression ratio of the ring die. However if fish feed floating pellet making machine does not have high demands for the molding rate of your pellets, then you can properly Lower the compression ratio, which can not only raise the outcome, yet also decrease the service life of the mold and also journalism wheel.

5. Roughness is additionally an important indication to gauge the high quality of ring die. Under the very same compression ratio, the higher the roughness value, the better the extrusion resistance of the sawdust bits, and the more difficult it is to release the material.

Too much roughness likewise affects the quality of the particle surface area. The appropriate roughness worth should be 0.8-1.6. between.

What To Do If The Mold Compression Ratio Is As Well Big.


1. Experienced operators will certainly change the wetness web content of the raw products or adjust the void between the ring molding rollers, and the pellets can be smoothly released without transforming the compression ratio. The procedure needs to be tape-recorded as well as checked detailed.
2.
2. Furthermore, the second pressurization can make the mold with a larger compression ratio smaller, yet modifying the ring mold will influence the firmness of the ring mold, so it needs to be identified according to the actual wear of the mold.

The roughness of the die hole of the pellet machine is also an important indicator to gauge the top quality of the mold, as well as the suitable roughness value need to be between 0.8-1.6.

Under the very same compression ratio, the larger the roughness value, the better the particle extrusion resistance, as well as the harder it is to discharge the material. Excessive roughness additionally impacts the high quality of the particle surface.
