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

Before pelletizer for sale is utilized, the compression ratio should be changed and determined. This is primarily to readjust the diameter of the mold, the density, the taper as well as reaming level of the bell mouth, the product of the mold, the hardness of the mold, as well as various products, there are various mold compression ratios.

So we have to readjust as well as determine according to our real situation, so what is the change calculation technique of the pellet machine mold compression ratio?

Compression Ratio Of Pellet Equipment Mold

The compression ratio of the pellet equipment die refers to the ratio of the reliable size of the die hole of the die to the die diameter, as well as is an index showing the extrusion strength of the pellet maker.

Pellet equipment mold compression ratio = mold hole size/ effective functioning size of mold opening

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

Assumption: The diameter of the die opening is 6mm, and also 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 step hole and also the outer tapered opening, the effective length of the die hole is the overall density of the mold minus the size of the release hole or the size of the external tapered hole, as well as the aperture of the small size section is the aperture for computing the compression ratio.

Assumption: the size of the ring die opening is 8mm, the die thickness is 66mm, and 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 same compression ratio, its aperture and also reliable working size might be various.

Exactly how To Pick an Ideal Mold Compression Ratio?

1. The aperture dimension and also outcome of the mold are carefully related to the inner size of the pellet equipment mold and the make-up of the raw materials. The typical aperture of 8-10 mm typically made use of in the market is called standard information.

The pellet maker larger than 10 mm needs better pressure for molding., Reasonably talking, the wear is also big, customers usually call it a biomass rod making machine or a rod making maker.


2. The efficient thickness of the mold is very vital for the molding of basic materials.

If the mold is too thick, the molding time of the raw material is much longer, the density of the fragments is relatively large, the extrusion is more difficult, the mold is thin and also very easy to break, as well as the density of the fragments is fairly little.

The pressing temperature level is reduced, the output is high, however the molding price is reduced or the molding is poor.

3. The compression ratio of abrasive tools is figured out according to the raw products. The compression ratio of poplar wood is 1:6, the compression ratio of pine 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 basic materials is different. The harder the raw material, the smaller sized the compression ratio, as well as the cosy the raw product, the better the compression ratio.

small poultry feed machine is to state, the extra fluffy the raw material, the simpler it is to be molded. small electric fish feed extruder machine price consists of a lot more fibers, as well as the more fiber-containing materials are much easier to shape.

4. Each little opening straight has 6 mm, 8 mm, and 10 mm. This 1 represents the size of each small hole. If the diameter of the ring die hole is 8 mm, then this 1 stands for 8, And also 6 stands for the efficient aperture.

The effective aperture is equal to the diameter of the hole multiplied by the reliable aperture size, 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 this way.

The high quality of the biomass pellet machine's result relies on the compression ratio of the ring die. Yet if the consumer does not have high requirements for the molding price of your pellets, after that you can appropriately Decrease the compression ratio, which can not just boost the result, but likewise reduce the life span of the mold and also the pressing wheel.

5. Roughness is also a vital indicator to gauge the quality of ring die. Under the very same compression ratio, the better the roughness worth, the better the extrusion resistance of the sawdust bits, and also the more difficult it is to release the product.

Extreme roughness additionally influences the quality of the fragment surface. The ideal roughness worth need to be 0.8-1.6. in between.

What To Do If The Mold Compression Ratio Is Too Big.

1. Experienced drivers will readjust the dampness material of the raw materials or change the gap in between the ring molding rollers, and the pellets can be smoothly discharged without transforming the compression ratio. The procedure requires to be tape-recorded and checked detailed.
2.
2. On top of that, the second pressurization can make the mold with a bigger compression ratio smaller sized, yet customizing the ring mold will impact the hardness of the ring mold, so it needs to be figured out according to the real wear of the mold.

The roughness of the die hole of the pellet machine is also a crucial indication to determine the top quality of the mold, as well as the proper roughness value need to be between 0.8-1.6.

Under the exact same compression ratio, the larger the roughness worth, the higher the particle extrusion resistance, and the harder it is to release the material. Too much roughness also affects the high quality of the bit surface.
