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

Prior to the pellet maker mold is made use of, the compression ratio have to be readjusted and determined. This is generally to adjust the diameter of the mold, the thickness, the taper and reaming level of the bell mouth, the product of the mold, the hardness of the mold and mildew, and also different materials, there are various mold and mildew compression ratios.

So we need to adjust and determine according to our actual situation, so what is the adjustment estimation technique of the pellet equipment mold and mildew compression ratio?

Compression Ratio Of Pellet Maker Mold And Mildew

The compression ratio of the pellet equipment die describes the ratio of the effective size of the die hole of the die to the die diameter, and also is an index mirroring the extrusion toughness of the pellet equipment.

Pellet equipment mold and mildew compression ratio = mold and mildew hole diameter/ reliable working length of mold and mildew hole

For a mold with a straight hole, the reliable size of the mold and mildew hole is the complete density of the mold, as well as the tiny size is the size of the mold opening itself.

Assumption: The size of the die hole is 6mm, and also 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 step opening and the external tapered hole, the efficient size of the die hole is the complete density of the mold minus the size of the launch opening or the length of the external tapered opening, and also the aperture of the small diameter area is the aperture for determining the compression ratio.

Presumption: the size of the ring die opening is 8mm, the die density is 66mm, and 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 very same compression ratio, its aperture and also effective working size might be various.

Just how To Pick an Ideal Mold Compression Ratio?

1. The aperture dimension as well as output of the mold and mildew are carefully pertaining to the inner size of the pellet equipment mold and the make-up of the raw materials. The basic aperture of 8-10 mm generally made use of in the industry is called conventional information.

The pellet equipment larger than 10 mm calls for better stress for molding., Reasonably talking, the wear is likewise big, users usually call it a biomass pole making equipment or a rod making machine.

2. The effective thickness of the mold is extremely important 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 density of the bits is relatively large, the extrusion is harder, the mold is thin and easy to damage, and the density of the particles is fairly tiny.


Journalism temperature level is reduced, the output is high, but the molding price is low or the molding is poor.

3. The compression ratio of rough devices is identified according to the raw materials. The compression ratio of poplar timber is 1:6, the compression ratio of ache wood is 1:7, the compression ratio of difficult 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 basic numbers, the compression ratio of different basic materials is different. The tougher the raw material, the smaller sized the compression ratio, and the cosy the raw product, the greater the compression ratio.

chicken manure pelletizer is to claim, the extra fluffy the raw product, the easier it is to be molded. dog food pellet making machine has more fibers, as well as the more fiber-containing materials are less complicated to form.

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

The effective aperture is equal to the diameter 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 outcome relies on the compression ratio of the ring die. But if the client does not have high needs for the molding rate of your pellets, then you can suitably Lower the compression ratio, which can not just increase the outcome, but likewise minimize the life span of the mold as well as journalism wheel.

5. Roughness is additionally a crucial indication to gauge the top quality of ring die. Under the same compression ratio, the higher the roughness value, the greater the extrusion resistance of the sawdust bits, and also the harder it is to discharge the material.

Excessive roughness additionally influences the top quality of the particle surface area. The proper roughness worth ought to be 0.8-1.6. in between.

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

1. Experienced drivers will adjust the wetness web content of the raw materials or change the gap between the ring molding rollers, and the pellets can be efficiently released without transforming the compression ratio. The process needs to be recorded and evaluated detailed.
2.
2. In addition, the 2nd pressurization can make the mold and mildew with a larger compression ratio smaller, but modifying the ring mold and mildew will affect the solidity of the ring mold and mildew, so it needs to be figured out according to the real wear of the mold.

The roughness of the die opening of the pellet machine is additionally an essential indicator to measure the high quality of the mold, and the appropriate roughness worth need to be in between 0.8-1.6.

Under the same compression ratio, the bigger the roughness value, the higher the particle extrusion resistance, and the more difficult it is to release the product. Extreme roughness likewise affects the quality of the bit surface.
