[0002] Microcrystalline cellulose is a non-fibrous white crystalline powder after purification and partial depolymerization of cellulose. It has a high degree of crystallinity, a particle size of about 20-80μm, and a degree of polymerization of about 15-375. Microcrystalline cellulose is odorless and insoluble in water, dilute acid, oil, and organic solvents. It has strong fluidity and can be dispersed in water and partially swelled in weak alkaline solutions. At the same time, it has relatively high performance in carboxylmethylation, acetylation, and esterification reactions. Due to these special properties, microcrystalline cellulose has been widely used in the pharmaceutical, food, cosmetics, and plastic industries as a filler, adhesive, suspending agent, and emulsifier. Microcrystalline cellulose will be made into filter cakes during the production process. The filter cakes need to be crushed and dried into powder before they can be used.

A collection box is placed at the bottom of the grinding device, and the drive motor one and the drive motor two are electrically connected to the control device. The beneficial effect of the utility model is that the utility model preliminarily pulverizes the filter cake through the extrusion roller device in the pulverizing device, and then enters the grinding device for grinding, and the fully ground microcrystalline cellulose is collected by the collection box.

[0005] However, the above method still has the following defects in actual use: no drying mechanism is provided, and the microcrystalline cellulose may stick to the machine due to moisture, resulting in unsatisfactory crushing effect, and also causing damage to the machine, affecting its service life.
