Herb Spice Grinder

 

 

JB series herb and spice grinder is composed of a hammer host, an ultramicro host, a cyclone separator, and a dust box. This grinding machine boasts several advantages, including eliminating the need for sieves and filters and producing uniform particle sizes. The continuous production process allows for the direct grinding of large particles into fine powder. This grinder mill is widely used in the pharmaceutical, chemical, and food industries.

 

The herb spice grinder machine can crush chili, pepper, black pepper, white pepper, green pepper, cinnamon, cumin, bandits, Dahongpao pepper, cinnamon, nutmeg, cardamom, red yeast rice, red pepper, garlic, star anise, cloves, Amomum Tsaoko, geraniol, turmeric, ginger, fennel, anise, angelica and other material with high content of oil or tiber. Besides, the material can be fed into the machine directly without coarse crushing. The grinding machine has the features of a big capacity, not changing the color, and maintaining the physicochemical characteristics of the material.

 

 

 

JB series herb spice grinder crushes materials into extremely fine powders through various physical processes such as impact, collision, friction, shearing, and grinding. Its core feature lies in the integration of both crushing and grading functions, typically operating in a closed system under negative pressure:

* Coarse Crushing Process: Material is quantitatively fed into the hammer mill chamber. Inside the chamber, materials are crushed by the violent impact, shear, collision, and friction caused by high-speed rotating hammers against the inner wall.

* Collection: The airflow containing fine powder enters the cyclone separator, where most of the finished powder is collected.

Convergence and Impact: The materials on both sides of the cylinder intersect at the bottom of the V-shape, producing intense impact and diffusion.

* Ultrafine Crushing Process: Material is quantitatively fed into the crushing chamber through a feeding system (e.g., a screw feeder). Inside the chamber, materials are crushed by the violent impact, shear, collision, and friction caused by high-speed rotating components against the gear ring of the equipment.

* Grading Process: The crushed material is carried upward by the negative pressure airflow generated by the induced draft fan into the grading zone. Graders (usually high-speed rotating impellers) generate strong centrifugal forces. Coarse particles are thrown back into the crushing chamber for further grinding due to centrifugal force exceeding airflow attraction, while fine powder that meets the fineness requirements passes through the classifier with the airflow.

* Collection and Dust Removal: The airflow containing fine powder enters the cyclone separator, where most of the finished powder is collected. Finer dust proceeds to the pulse bag filter (or filter cartridge) and is captured, while clean air is discharged by the induced draft fan. The pulse-jet cleaning system periodically cleans the filter bags to maintain filtration efficiency.

 

The entire process is continuous, and the fineness of the output material can be precisely controlled by adjusting the speed of the grading wheel; higher speeds result in finer powder.
