MR series herbal / spices grinding machine is composed of a hammer host, an ultramicro host, a cyclone separator, and an impulse dust box. The grinding machine has a variety of properties such as no screen, no mesh, uniform discharge particle size, etc. The production process is continuous and can directly load large particles Crushed into fine powder.This machine is applied in sucH trades as pharmaceutical, chemical, foodstuff, etc.
The grinding 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 big capacity, not changing the color, maintaining the physicochemical characteristics of the material.
Compact design, compared to the micro-grinding unit, more pre-processing hammer for coarse crushing, so that large particles of material can be directly crushed, continuous crushing process, no dust. Fine powder trapped by dust traps can be effectively recovered, reducing the material loss rate.
The material enters the grinding chamber via the funnel and spiral conveyor where it is sheared and broken by the fast-rotating blades. The powder passes the guide ring and enters the classification chamber. As the classification wheel is in revolution, both the air force and centrifugal force act on the powder. As the particles whose diameters are greater than the critical diameter (diameter of the classification particles) have a great mass, they are thrown back into the grinding chamber to be ground again, while the particles whose diameters are smaller than the critical diameter enter the cyclone separator and bag-type collector via the material exit pipe by means of negative pressure wind conveyance. The discharge material meets the requirement for the product.

Q: What are the application fields of your machines?
A: Used in food additives, baking ingredients, pharmaceutical intermediate, health food, chemical raw materials and other industries.
Q: What information do I need to get a quote for a powder grinding machine?
1. What is the size of material ? For example chilli, spices, turmeric rice grain or others?
2. What capacity you expect by one grinder machine ? (kg/h)
3. What mesh or mm or micron(size) of the powder you want?
Q: What is the material of the machine?
A: Usually we use stainless steel 304, if you want stainless steel 316, it’s OK and please tell us.
Q: Is it convenient to clean the equipment?
A: Yes, cleaning convenience is one of our core design considerations.
1. Quick opening structure: using quick opening clamps, etc., it can be quickly opened without tools.
2. No dead corners design: The inner wall of the container is smooth and fluid, avoiding material residue.
3. Cleaning methods: Supports various methods such as dry cleaning and wet washing.
Q: How to control dust overflow and protect the production environment?
A: We offer multiple options: the device can be designed as a fully enclosed structure; Equipped with an integrated bag filter or filter dust collector as an optional accessory.
Q: Will there be heat during the crushing process? How to control the temperature?
A: Mechanical crushing does indeed generate heat. For heat sensitive materials, we offer multiple cooling solutions:
1. Built in cooling jacket: cools the grinding chamber through circulating cooling water.
2. Airflow cooling: Use a cold air fan to cool the cavity.
Q: What is the lifespan of easily worn components such as blades, screens, and gear rings?
A: The lifespan depends on the hardness and abrasion resistance of the material. For high hardness materials, we provide vulnerable parts made of advanced materials such as wear-resistant alloys and tungsten carbide to greatly extend their service life and reduce maintenance costs.
Q: How to obtain spare parts?
A: We maintain inventory of commonly used spare parts and can ship them quickly. You can place an order directly through your sales representative. We provide original spare parts drawings and lists for your convenience in management.
Q: How quickly can you respond when problems arise?
A: We provide 7×24 hour technical hotline support. For urgent issues, our engineers will first provide remote guidance through phone/video calls to resolve them. If it cannot be resolved, we will arrange engineers to go to the site as soon as possible according to the situation.
