The Compression Ratio Of The Pellet Equipment Mold
The Compression Ratio Of The Pellet Machine Mold And Mildew

Before the pellet equipment mold is used, the compression ratio need to be readjusted and also determined. This is primarily to change the size of the mold and mildew, the thickness, the taper and reaming level of the bell mouth, the product of the mold, the solidity of the mold and mildew, and different materials, there are various mold compression ratios.

So we have to readjust as well as determine according to our actual circumstance, so what is the modification calculation technique of the pellet equipment mold and mildew compression ratio?

Compression Ratio Of Pellet Maker Mold And Mildew

The compression ratio of the pellet machine die refers to the ratio of the effective size of the die opening of the die to the die size, and also is an index reflecting the extrusion toughness of the pellet machine.

Pellet equipment mold compression ratio = mold and mildew opening diameter/ reliable functioning size of mold and mildew opening

For a mold with a straight hole, the reliable size of the mold and mildew opening is the complete density of the mold, and the small size is the diameter of the mold hole itself.

Presumption: The diameter of the die hole is 6mm, and 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 floating feed extruder machine and also the external tapered hole, the efficient size of the die hole is the total density of the mold minus the size of the launch opening or the size of the outer tapered opening, as well as the aperture of the small diameter area is the aperture for determining the compression ratio.

Assumption: the diameter of the ring die opening is 8mm, the die density is 66mm, as well as the release opening 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 as well as reliable functioning length might be different.


How To Select an Appropriate Mold Compression Ratio?

1. The aperture size as well as outcome of the mold are very closely related to the inner diameter of the pellet maker mold and mildew as well as the structure of the raw products. The typical aperture of 8-10 mm typically utilized in the industry is called standard information.

The pellet maker larger than 10 mm requires greater stress for molding., Fairly talking, the wear is additionally large, users generally call it a biomass pole making machine or a rod making maker.

2. The efficient thickness of the mold and mildew is really vital for the molding of resources.

If the mold and mildew is as well thick, the molding time of the raw product is much longer, the thickness of the particles is fairly large, the extrusion is more difficult, the mold and mildew is thin and very easy to break, and also the density of the fragments is reasonably little.

The pressing temperature level is low, the result is high, but the molding price is reduced or the molding is poor.

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

From these easy figures, the compression ratio of various raw materials is different. The more difficult the raw product, the smaller sized the compression ratio, and also the fluffy the raw material, the higher the compression ratio.

That is to state, the more fluffy the raw product, the less complicated it is to be built. The even more fluffy raw material contains more fibers, and the even more fiber-containing materials are easier to form.

4. Each tiny hole directly has 6 mm, 8 mm, and also 10 mm. This 1 stands for the diameter of each tiny hole. If the size of the ring die hole is 8 mm, after that this 1 stands for 8, As well as 6 represents the reliable aperture.

The efficient aperture is equal to the size of the hole increased by the effective 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 timber. It is transformed in this way.

The high quality of the biomass pellet machine's output depends on the compression ratio of the ring die. But if the customer does not have high demands for the molding rate of your pellets, after that you can properly Minimize the compression ratio, which can not only boost the output, yet also decrease the service life of the mold and also the pressing wheel.

5. Roughness is also a vital indication to gauge the high quality of ring die. Under the exact same compression ratio, the greater the roughness value, the better the extrusion resistance of the sawdust fragments, and also the harder it is to discharge the material.


Too much roughness likewise affects the top quality of the fragment surface. The proper roughness worth need to be 0.8-1.6. in between.

What To Do If The Mold And Mildew Compression Ratio Is As Well Huge.

1. Experienced drivers will certainly change the moisture material of the raw products or readjust the gap between the ring molding rollers, and the pellets can be smoothly released without transforming the compression ratio. The procedure requires to be tape-recorded as well as tested detailed.
2.
2. Furthermore, the second pressurization can make the mold with a bigger compression ratio smaller, however customizing the ring mold and mildew will affect the solidity of the ring mold, so it needs to be identified according to the real wear of the mold.

The roughness of the die hole of the pellet maker is additionally an important indication to determine the high quality of the mold, and the appropriate roughness worth ought to be in between 0.8-1.6.

Under the very same compression ratio, the larger the roughness worth, the better the particle extrusion resistance, and also the harder it is to discharge the material. price of poultry feed making machine affects the quality of the fragment surface area.
