Various types of grain cleaning equipment use different working principles to separate grain particles from impurities. Commonly used separation methods include separation by particle size, separation by specific gravity, separation by natural characteristics of impurities, separation by shape, etc. The cleaning equipment of RICHI machinery is SCY Drum Type Pre-cleaner, SCQZ Powder Cleaning Screen, SFJH Rota-shake Sifter and TCTX Permanent Magnet Sleeve.

Primary Crushing is the pre-treatment process of ultrafine pulverization in aquatic feed processing. Its main purpose is to reduce the particle size difference and variation range of materials, improve the working condition of the ultrafine pulverizer, and increase the efficiency of the ultrafine pulverizer. And guarantee the stability of product quality.

The raw materials will be pulverized, granulated, mixed, and packed from feeding to granulating. A complete feed pellet production line generally has a pulverizing bin, a granulating bin, a mixing bin and a packing bin.This is what we call the Batching Section.

Primary mixing, a single-shaft horizontal ribbon mixer can be selected. At the same time, a grease addition system must be considered on the mixer. The first batching and mixing is also a pre-treatment process of ultrafine crushing, which is mainly to reduce the variation range of the particle size of the material, improve the working condition of the grinder and improve the working efficiency of the grinder to ensure product quality.

To have a homogenous mix, micro materials, premix, minerals and vitamins are added to the mixing machine . Additives are added in certain amounts on each charge. They are crucial on pellet feed’s grade.

Secondary crushing and secondary mixing. In the secondary pulverization process, ultra-fine pulverizer is used, which is equipped with a powerful air separation device, and then enters a rotary classification screen for screening.Various ingredients enter the secondary mixer after secondary dosing.At the same time, the mixer is provided with a liquid adding mechanism for adding grease.In the secondary mixing process, in order to ensure the key to product quality, the mixer must choose a model with good performance.Such as the twin-shaft horizontal paddle mixer, which has high mixing uniformity, high output and fast mixing speed.

In the extrusion puffing process, the material actually undergoes a cooking process under high temperature, high humidity, and high pressure conditions. Puffed feed, because this kind of feed not only has the advantages of general hard pellet feed --- good palatability, avoids automatic classification of products, facilitates transportation, helps digestion, reduces waste during feeding, etc., but also has unique advantages : The starch has a high degree of gelatinization, and the protein is easier to digest, which improves the animal's utilization rate of the feed. It has excellent floating properties, which is convenient for observing the feeding situation of fish, and it can control water pollution to the greatest extent. These are also the main reasons why extruded feed is widely used.

SKLN Series Counterflow Cooler is the most advanced pellet feed cooling technology in the world. It is a new generation of cooling equipment researched and developed. It is mainly used to cool pellet pellets at high temperature after pelleting.

There are three kinds of automatic packaging machines produced by RICHI machinery: powder packaging machines, granule packaging machines and (universal) dual-purpose packaging machines.


Why Make Sawdust Pellets?

Sufficient and cheap sawdust material source: Sawdust is the residue of wood processing factory. The amount of sawdust material is large and the price is cheap. Sawdust pellet mill can also be used to deal with life wastes such as leaves, straw and crops waste. It is a way to make waste profitable. And by making these biomass materials into fuel pellets, we no longer have worry how to dispose of these wastes.

Great demands for sawdust pellets: As the price of coal rise, finding coal fuel replacement is urgent. More and more people turn to biomass pellets. The market demand is large. Sawdust pellets not only be used at home in our daily life, but also can be applied to industrial production such as power plant.

Richi Machinery easy to maintain sawdust pellet plant production line is biomass fuel equipment which can process eucalyptus, birch, poplar, fruit and crop straw, bamboo chips into pellet. Which can effectively solve the coarse fiber difficult to pelletize. The wood must have been debarked prior to passing through the saw mill. Sawdust of hardwoods can be missed in with that of softwood, but successful production of hardwood pellets without binders is more difficult.

How to Make Sawdust Pellets?

Sawdust preparation

As the sawdust arrived in the sawdust pellet machine plant, the moisture content should be tested. The moisture content gives the proportion of evaporable water in the total weight of material. The sawdust with high moisture content should be stored separately from the low moisture content sawdust. The production of 1 ton pellets needs the about 7 bulk m³ sawdust with the moisture content around 50-55%. The optimum moisture content of the sawdust is 10-15%. The sawdust with higher moisture content should be dried before entering the sawdust pellet machine while the lower one can skip the procedure.


The wet sawdust should be dried before size reduction because the wet sawdust consume more power to be hammered than the dried one does. And also the wet sawdust may risk the screening by clogging or smearing the screen. Drying can be done by the dryers.


The screening of the sawdust is to remove the stones, plastics, metals, or other hard materials that may damage the equipment. The stones and stone like hard materials are removed by a stone trap when the sawdust passes over the screen while the metals are picked up by a magnet .


The hammering is meant to homogenize the sawdust to an even-size. In the piles and piles of sawdust there are might be wood lumps, dead knots, etc. which needed to be hammered so that they can pass the die holes of the sawdust pellet machines.


When the sawdust goes into the pelletizing chamber of the sawdust pellet machine, the lignin of the sawdust will be heated up to 120-130 ℃ by the heat produced by the running sawdust pellet machine and by which the lignin will be plasticized and binds the particles together to help to mold the pellets. The pellets are molded by being pressed through the pellet dies of the sawdust pellet machines and then are cut off by the cutter with the desired length. During the pelletizing, the binder may be needed to improve the pellet strength and durability.


The moment when the pellets leave the sawdust pellet machines, they are hot and plastic. Then they need to be cooled down to become hard and rigid and to dry up so that the final moisture content after the cooler can be as low as 6% which may be increased up to 8 to 10 % by absorbing moisture from the surround air.


Before packaging, the pellets will be screened again for recycling the fines. And then the pellets will be packaged. For domestic users, the pellets are preferred to be packed into bags with the sizes of 12, 15, or 20 kg. while for exporting, the pellets are usually shipped in one tone bags or in bulk which are usually wrapped in plastic to keep the moisture out. Compare with the large bulks or bags, the small bags are better for the pellets because the pellet are subject to less abrasion during delivery.

Advantages of Sawdust Pellets

Application of Sawdust Pellets

1.Home cooking and heating. Sawdust has high combustion with low ash content, so it is suitable for home cooking and heating.

2.Biomass boiler. Being one common biomass material to be used in biomass boiler, sawdust pellet is similar to EFB pellet, the difference between them is the feedstock.

3.Household BBQ rack. Regarding of renewable and environmental protection, catering industry and domestic BBQ like to take sawdust pellets as fuel replacement. Besides compared with charcoal, sawdust pellets makes BBQ much cheaper.

4.Power plant. Along with the international demand to reduce CO2 carbon dioxide emissions, biomass pellets is becoming a more and more popular fuel to generate power.
