First look at what kind of raw material you have in your hands. If you use wood chips and shavings as raw materials, the size must be able to pass through the sieve of about 8mm-12mm. (So many branches and branches in the hands of customers and friends, as well as some discarded boards, must be After crushing, even to increase the production capacity, it needs to be sliced ​​and crushed); moisture we require 10%-16% moisture, no more than 2-4% moisture, if the moisture is too large, we need to equip you with drying equipment Up. If the moisture is too small, use wood chips with relatively high moisture content to mix and stir to the proper moisture.

In summary, the configuration of the production line can be divided into slice crushing section, drying moisture pretreatment section, mixing buffer section, granulating section, packing section, and supporting electrical control system, dust treatment system, conveying system, temperature control system, etc. Several major projects.

In terms of the main machine of the granulator, we use a ring die granulator, which is called a circular die granulator. It is composed of a vertical ring die and an internal roller, and pressure is applied to the ring die (ring die). The raw materials in the conveying system enter the center of the granulation chamber through a fan propeller. In the granulating room, the roller (composed of pressure roller and main shaft)

It is static, and the mold (ring mold) is moving, similar to a washing machine. The raw material passes through a rotating die and then is squeezed by a roller. The ring die pelletizer will not have uneven rollers, and because the distance between the inner and outer edges is equal, there will be no wear. It is more suitable for mass production and manufacturing. First, the loss value of the roller and mold is relatively low at this time; second, it has a higher energy efficiency. Due to the additional friction generated by the sliding of the roller, the flat die pelletizer needs to consume more energy. Huasheng Machinery adopts air circulation to achieve the purpose of controlling temperature and eliminating excess water vapor. The temperature in the pelletizing chamber is changed from more than 200 degrees to 80-100 degrees Celsius, which greatly reduces the temperature stress of the ring die and thus changes the non-compression zone. The working environment can extend the life of the ring die, extend the life of the roller bearing, realize continuous production, and effectively reduce the cost. The life of a single ring die has been increased from 250-300 tons to 800-1000 tons.
