Wood grain production line is made of solid fuel wood waste process.Sawdust particles通常由壓實的鋸木屑和相關的工業廢料製成，這些廢料來自木材的銑削、傢俱和木製品製造以及建築時所產生的廢料。
In the production of wood particles, we need to pay attention to some important variables (variation factors), such as the raw material purity, moisture content, granularity and granular strength.Should provide complete technology solutions and consulting services, help you into sawdust particles business smoothly.
The raw material
Sawdust particles of raw materials will differ due to different sources.It may be a long strip, plate, sawdust, and many other shapes;So you need to pre grinding to decrease the size of materials.
Before crushing
In view of the coarse particle materials optional process.
After crushing will reduce shatter the required energy.
Temporary barrels
Each bucket can be installed on the same day the raw material for production.
Batching and weighing
Raw material will be according to the recipe ingredients
After crushing (optional)
After crushing were reduced in the process of production raw material size final process;This step can be omitted if there is no need to.
hybrid
In the mix, you can add some water, oil or other liquid to help granulating process.
granulation
Granulating starting from the preset quality, add steam further hydration, and on into the granulating chamber to form particles of raw materials before cooking.
cooling
Using the surrounding air cooling hot particles from granulator.
Need a thorough cooling in order to prevent the packing in the condensed water bead.
packaging
Packaging can provide protection for particles, also facilitate handling and transportation to the customer.
Sawdust particles granulating process
Appropriate large granulating machine with high productivity, low energy consumption production high quality particles.Through the special die and roller shell design, the production cost can be reduced to a minimum.The design of the roller combination easy to adjust the gap between the roller and die.For different raw materials, proper clearance work will help roller shell and achieve maximum capacity.The size of the particles by net die aperture control, network mode of compression ratio on grain quality and yield is crucial.
After granulation process of sawdust particles is hot.cooling機利用周遭空氣減少水分並將顆粒的溫度降低至室溫的 ±5 °C，冷卻可延長木屑顆粒的保質期。
After the production of particles will be through a sieve to remove any irregular particles and dust.
In accordance with the weighing sensor and bagging machine set, the weight of the sawdust particles bagging, and seal after storage.After packing finished product can be by truck or container bags.
Appropriate process design and equipment characteristics and advantages
Appropriate big believes that conform to the purpose of design strategy.We realized that our customers facing the rising raw material costs, rising energy costs and overhead costs, however, in the face of these challenges, we still hope to the competitive market with high quality products.Our design concept is constantly improve and improve the technology and equipment, the maximum success for our customers.The following describes some of the features and advantages by this idea.
All the equipment can design is based on the concept of continuous production, and make the outage time to minimize the gap refueling, appropriate product's mission, is after the installation, in addition to the consumption of regular maintenance and parts replacement need downtime, all of the devices can be production all year round.
Two aspects are affecting the recipe: use effect and the efficiency of the machine.For example, choosing the appropriate source of wood is very important.Is not appropriate wood source can reduce the steam mixed with level and cause the clogging in granulator.Fat and moisture content in the production of crusher plays an integral role.
Appropriate big dual-axis mixer each axis of independent driven design reduces the power consumption and noise.When the blade reversal chamber can be completely empty.Atomizing nozzle to further improve the overall efficiency of steam and water conditioning efficiency, subsequent conditioning system using steam jacketed clamp (or hot) insulation for conditioning the uniform mixture almost no water;Preset quality deficiency can lead to crack of particle surface and generate dust.
Reflux cooler for cooling particles and extrudate.Temperature (hot) particles into the cooling chamber, suction fan will indoor air out of the surrounding air from the bottom of the fresh into the cooling chamber, promote grain cooling effect.When the particle accumulation and access to the high limit yuan sensor, pneumatic discharge valve will be action to discharge the product immediately.Countercurrent air heat exchange to ensure high cooling efficiency.
