Squeezing granulation does not require heating and humidification of materials, saving investment and energy consumption. It can adapt to materials containing heat sensitivity, and there is no wastewater or exhaust gas discharge during the production process, which will not pollute the environment. The squeezing granulation process is short, easy to operate, and convenient to achieve production automation control, improving production efficiency. If round particles are needed, they can be matched with a round throwing machine to achieve it.
