Vertical ring-die wood pellet mill 1, product introduction
Our company independently developed and produced a series of vertical ring-die wood pellet mills, absorbing the advantages of domestic and foreign pellet mills. The mold is placed vertically and flat, and the pressing area is divided into two layers. , and the mold and pressure roller are made of high-alloy wear-resistant materials. They have the characteristics of reasonable design, unique structure, stability, efficiency, and long life. The vertical ring-die wood pellet machine developed by our company according to the needs of the market and customers has achieved the best results of the pellet machine, occupied a certain market, and is at the leading level in the same industry. This product is suitable for pressing materials that are oil-free and dispersed after being dried in a dryer. Such as: rice husks, sunflower seed shells, peanut shells and other shell materials, eucalyptus branches, eucalyptus sawdust, wood bran and other wood scraps, corn straw, cotton straw and other crop straws. This product is also widely used in biomass fuel. Factory, power plant, wood processing plant.
2. Main performance differences from similar products:
, Six major features:
. The mold is laid flat, the material is fed directly, the material can be adapted to a wide range, and the heat dissipation is strong.
. The mold is vertically double-layered, which improves utilization, reduces costs, and is the most cost-effective.
3. The pressure roller adopts a unique equilateral triangle distribution, which increases the extrusion frequency, makes the operation more stable and efficient, and ensures the transmission accuracy of the equipment.
.The unique separation design of the spindle ensures the concentricity of the equipment and reduces the failure rate of the equipment.
.No need to shut down, the whole machine realizes hourly fully automatic intermittent lubrication, extending the life of equipment wearing parts.
.The centrifugal force of the pressure roller and the extrusion force are combined to ensure the molding and smoothness of the particles and increase the output.
B. Three major differences
． The mold is placed vertically and flat, with a unique structure and direct feeding, which is conducive to heat dissipation: the material is fed into the granulation chamber in a free-falling state, so that the material falls directly into the pressing area, improving the feeding efficiency. The feed port of the horizontal ring die granulator is installed on the side. It is difficult for materials with light specific gravity to enter the granulation chamber. A forced feeding device is required to force the materials to the granulation chamber. The heat dissipation effect of the granulation chamber is poor, which greatly reduces the cost of the transmission system and the mold. Bearing service life. Flat die granulators have two structures. Although they can feed materials in free fall, they both have many disadvantages that are difficult to eliminate. In flat-die granulators where the die plate rotates and drives the pressure wheel to rotate, the material is prone to arching and forming a material layer, which affects the output.
The mold plate is stationary and the pressure wheel rotates. Although it does not arch, it generates centrifugal force, which throws the material falling into the granulation chamber to the surroundings, so that there is no material in the pressing area of the granulation chamber and is in the same direction as the mold hole. Vertical, causing material accumulation and uneven thickness, greatly reducing output.
． The mold is placed flat and stationary, and the pressing wheel rotates with the spindle, causing the material to generate centrifugal force, which evenly throws the material to the pressing area. Then, with the help of the rebound effect of the second-layer pressing area of the mold, it is evenly distributed on the surface of the annular mold pressing area. In the horizontal ring-die granulator, the pressure wheel is stationary, and the mold rotates with the main shaft, which cannot generate centrifugal force. The material distribution is uneven, causing the machine load current to be high and low, and reducing the service life of the pressure wheel bearings and the mold. Although the flat die granulator generates centrifugal force due to the rotation of the pressure wheel, the direction of the mold opening is perpendicular to the centrifugal force generated by the material.
3. The second-layer pressing area of the mold extends the life of the mold and increases the strength of the mold. The mold has two layers of pressing areas. Customers can choose two different aperture sizes to produce two different sizes of finished granules, which reduces the cost of using molds with different apertures.
