Experiences in operation of Sawdust charcoal briquette machine

Although the production process of the Sawdust charcoal briquette machine is complex, the mastering degree mainly depends on your experience in operation of the Sawdust charcoal briquette machine. If you are familiar with every step of sawdust charcoal briquettes, it is easy to operate. However, it is difficult to understand the operation mode of a whole set of equipment. Basically, you should have a general understanding of the operation process of sawdust charcoal briquettes and summarize the experience in the actual operation. Here are some experiences summarized in the operation of sawdust charcoal briquettes:

1. The combination degree of materials and water determines the degree of drying, energy consumption and duration of materials stay in the dryer, and is closely related to the selection of types. For example, give longer durations to materials that are difficult to dry rather than enhance the external condition of drying.

2. Conditions of materials, from formed lumber, ceramic to flake, fiber, pellet, fine powder, and paste and liquid are the materials that need to be dried in the industry. Therefore, choose the drying machine according to the shape of the material.

3. Physical characteristics of materials.

4. Characteristics of materials in the drying process. Including thermal sensitivity, some materials will be changed in color and decompose after heating. In addition, the shrinkage of materials during drying will crack or deform the molded products, thus reducing the product quality and even scrapping. Including density, heap density, particle size distribution, heat capacity and material adhesion, the adhesion performance has a great impact on material processing and charcoal dryer. When extreme adhesion will cause the drying process to fail to carry out.

Vulnerable parts of sawdust press equipment

The Sawdust briquette machine has components that are vulnerable to damage during intensive operation, including molding cylinders, thrusters, cone sleeves, straight sets, heating loops, and so on. Some of the brittle parts of the Sawdust briquette machine can be repaired but some worn out must be replaced. The introduction of it is as follows.

The screw propeller, which is the most complete and as the technology-intensive budget, is one of the most important parts of the Sawdust briquette.

Generally, the wear time is about a week but may be extended for a few days under the operation by the professional, or it may be shortened for a few days under correct operation.


The rod – making depends on the Angle of the propeller.

If the propeller is at the wrong Angle, or if the propeller the front end is worn, there will be problems in the production process, such as zero rod making and rod made with poor quality.

In this regard, the manufacturer will teach you how to repair the propeller, the process is: first, welded by the high-wear-resistant welding rod, then cooling naturally in the wood ash (do not soak into water directly, so that the service life of the propeller will be reduced), and then grinding on the grinder to a certain Angle. The second is the Angle problem, needs the customer to use for a long time to be able to master the skill. Generally speaking, it will take at least three months to master the welding mill technology, so it is necessary to communicate with and learn from technicians as much as possible during the installation process. Generally speaking, good thrusters will be damaged during a year or two, but if the welding mill is of poor quality, it may not take the time that long.

Unlike a screw propeller, a molded barrel is a part irreparable.

There is a cone sleeve embedded in the molding barrel, which is usually worn by the cone sleeve part. If the cone sleeve is worn, it needs to be replaced and install with a new one. If the molding cylinder is worn out, the complete set needs to be replaced. Generally, a forming tube will wear out after a year or two use.

And others be like the heating coil, straight set, can use for 3, 5 years commonly, replacement cost is cheaper.

Charring process of charcoal making machine

Charcoal is regarded as a good fuel due to its characteristics of inflammability, fire resistance, low ash content, and no sulfur.

In fact, due to its unique micro-pore structure and strong adsorption capacity, charcoal has been widely used in fields like food, pharmacy, chemical industry, metallurgy, national defense, agriculture, and environmental protection.

To produce charcoal, it is the key to use the charcoal machine reasonably.

The charcoal making machine needs four steps: comminution, drying, molding,and carbonization.


Using the charcoal machine to carbonize is the final and the most important step. Carbonization refers to the processing the raw rod into the carbonization furnace, which takes 7 hours. The carbonization process shall go through the following steps:

1.Drying: there is no chemical change in this step. The moisture in the sawdust bar is dried under the condition of external heat. The reaction is slow and white gas is emitted. This whole step completes in about 6 hours. After sealing the kiln for 2 to 4 hours, the water vapor produced within the kiln must be discharged in time, and the time-control is most important at this stage, otherwise, the water vapor in the kiln will damage the wood chip rod.

2.Pre-carbonization: component relatively unstable cellulose begins to decompose. The color of the gas changes gradually changed from white to brown. The gas can be recycled to extract wood acetic acid. This stage is shorter and easier to control. If the gas is not recycled, it can be ignited into pollution-free emissions.

3.Carbonization: cellulose and lignin, which is the main components of the rod, begin to pyrolyze violently, and the gas turns into dark brown in color. The emissions composed of liquid (acetic acid, methanol, wood tar) and gas (carbon dioxide, methane, ethylene, etc.), have great recycling value. If not to recycle, it can be ignited. This is the main process of carbonization, which takes a long time and is difficult to control.

4.Calcining: the pyrolysis process is basically completed, with no gas emitted, mainly to discharge the volatile residuals, so as to increase the content rate of fixed carbon, and the resulting gas can be ignited. This process has a great impact on the quality of carbon. If the calcination temperature is insufficient, it will cause the low fixed carbon content rate, excessive volatilization, poor shrinkage, and poor intensity, and poor quality.

Knowledge and introduction of plastic granulator

The details of the processing of plastic granulators are relatively rare, and the plastic granulators produced by Shuliy Plastics Machinery Co., Ltd. are widely used, and their performance and quality are also excellent, which is deeply supported by customers. Accreditation, so this article is the Shuliy Machinery Factory combined with its own years of experience and some of the knowledge on the network to organize and summarize, for your reference and reference.

In addition to polymers, plastic granulator processing ingredients, plastic granulator processing materials, generally also add a variety of plastic additives (such as stabilizers, plasticizers, colorants, lubricants, reinforcing agents and fillers Etc.) to improve the molding process and the performance of the product or to reduce the cost of the product. The additive is overmixed with the polymer and uniformly dispersed into a powder, also known as a dry blend.

The history of plastic granulators can be traced back many years, and the processing of plastic granulators has evolved with the development of synthetic resins and has been promoted with the development of plastic machinery. After the birth of celluloid, because of its flammability, it can only be formed into a block by molding, and then mechanically processed into a sheet. The sheet can be processed by thermoforming, which is the earliest plastic granulator.

Casting is a successful injection molding process with the advent of phenolic resin. It is used in the processing of cellulose acetate and polystyrene. In the middle of the year, the development of soft polyvinyl chloride extrusion molding, plastic-specific single-screw extruder Correspondingly, the twin screw extruder was put into production the following year. At the beginning of the year, polyurethane foam was produced and blow molding technology was used to produce polyethylene hollow products. The introduction of reciprocating screw injection machines has brought injection molding technology to a new stage.

In the years, the newly developed plastic granulator processing technology includes various new reinforced plastic molding methods, such as winding, pultrusion, sheet molding, reaction injection molding, structural foam molding, profile extrusion, sheet Solid phase forming and co-extrusion, co-injection, etc. In the late years, the processing of plastic granulators was moving toward high efficiency, high speed, high precision, energy saving, large-scale or ultra-small, ultra-thin, etc. Computer technology entered this field and improved the processing technology of the whole plastic granulator to a new one. Level.

The first two processes of plastic granulation machining. The ingredients are the basic part of two plastic granulation machining. Below I will introduce the molding, machining, joining, surface modification and assembly of plastic granulation machining. An article or blank of the desired shape is formed. There are more than thirty molding methods, and the choice depends mainly on the type of thermoplastic or thermosetting starting form of the plastic and the shape and size of the product.
Plastic granulation Mechanical processing of thermoplastics commonly used in extrusion, injection molding, calendering, blow molding and thermoforming, plastic granulation mechanical processing thermosetting plastics are generally molded, transfer molding, but also injection molding. Lamination, molding, and thermoforming are the shaping of plastic on a flat surface. The above plastic granulation mechanical processing method can be used for rubber processing. In addition, there are castings using liquid monomers or polymers as raw materials. Among these methods, extrusion and injection molding are used most and are the most basic molding methods, and are transferred to the parts. Many household appliances, building products, daily necessities, etc., use this method to obtain patterns such as metallic luster or wood grain.

Plastic granulator processing generally includes plastics in the formulation, molding, machining, joining, modification and assembly. The four processes after the processing of the plastic granulator are carried out after the plastic has been formed into a product or a semi-product, which is also called secondary processing of plastic. Plastic granulator processing is a general term for various processes for converting synthetic resin or plastic into plastic products.

Charcoal making machine workflow

Under normal circumstances, the production process of shuliy charcoal making machine equipment is divided into the following four steps, and then explained in detail:

1. Crushing through a pulverizer

The quality and quality of crushing is an important step to measure the quality of the charcoal produced. After repeated testing and experiment by the British mechanical experts, it is better to crush the raw materials of the small-scale charcoal machine equipment to less than 3 mm. For full smashing, it is recommended to use 2 times of pulverization or 3 times of pulverization. The blade of the stalk smasher is made of manganese steel alloy and carbon-added blade, which has stable working performance and high pulverization efficiency.

2, dry – fast drying in the case of dryness

Only when the raw materials are dried to a moisture content of 6% to 12%, is the precondition for producing good quality charcoal. Usually, the dryer is used to complete the drying. The drying speed of the dryer is recommended by our recommended configuration. It can reach a speed of 0.6 tons per hour, the temperature control is accurate, it can be adjusted at 190-300 degrees, and the fuel can be used in the drying process, and the dryer saves raw materials.

3, the rod

After pulverization and drying, it enters the key steps of charcoal manufacturing. After this step, charcoal can be produced, usually by sawdust briquette machine, and the sawdust briquette machine is also key equipment in the charcoal production line. The Sawdust briquette machine produced by the British has many models and has a high-quality 50-type sawdust briquette machine. The quality is good, the rod making speed is fast, and the forming efficiency is high.

4, carbonization

After being formed by sawdust briquette machine, it can only become mechanism charcoal after carbonization in the carbonization furnace. This step is very important. It is difficult for the operator to control the temperature. Therefore, it must be operated in strict accordance with the regulations and be skilled. grasp.

Matters for installing a new rotary dryer

During the operation of the user to operate the new rotary dryer equipment to dry the material, the airflow state in the cylinder directly affects the performance of the new rotary dryer equipment. If we improperly install the exhaust pipe, it is likely to cause excessive energy consumption, too long drying time, and even a large safety hazard. Then, what should be the intention when installing the exhaust duct of the new rotary dryer equipment?

New dryer

1. Follow the principle of small resistance joints. When installing the exhaust duct for the new rotary dryer equipment, to prevent it from being connected to the right angle of the main pipe, it must be inclined at an angle in the direction of the exhaust or by rounding to avoid the circulation resistance.

2, to achieve the principle of cross-section accumulation. When we use multiple new rotary dryer equipments to combine exhaust, in order to ensure the smoothness of the exhaust, it is necessary to ensure that the cross-sectional area of the exhaust duct of the dryer should be greater than or equal to the area of the exhaust duct of the front-end dryer. with.

3. When we install the exhaust pipe of the new rotary dryer equipment, we must pay attention to the installation of the induced draft axial fan and the damper in the exhaust main pipe, so that the exhaust pipe can be in a negative pressure state at any time to avoid cross gas or spontaneous combustion. The phenomenon occurs. In addition, in the drying operation, attention should be paid to the cleaning work of the exhaust duct of the new rotary dryer equipment to keep the air venting smooth, and the static pressure is controlled at 7.6 mm water column.

4. For the exhaust vent of the new rotary dryer equipment itself, the oscillating wind page should be set, so that once the gas condensing phenomenon occurs, the damper can be closed to prevent the airflow from flowing back into the dryer.

5. If the new rotary dryer equipment works in a closed room, it is necessary to open an air inlet to ensure that the area is 4-6 times the cross-sectional area of the exhaust duct to ensure that fresh low-humidity air can be replenished in time. When conditions permit, it is recommended that the dryer equipment is installed side by side, and the new rotary dryer equipment, except for the working surface, is enclosed in a room, and the radiant heat of the body and the exchanger is used to heat the fresh cold air. Save energy.
