MR series coarse crusher is applied as supporting equipment,before fine crushing process in such trade as pharmaceutical, chemical and foodstuff etc. which has better crushing effect for any material without limitation on its viscosity, hardness, softness and fiber etc.
Coarse crushing machineof horizontal crushing structure, and the material is fed into the crushing chamber through a hopper, crushed by cutting and impact of both fixed and rotating knives, and flows to the exit automatically under the effect of rotating centrifugal force. Designed according to GMP standard and whole made of stainless steel, this coarse crushing machine has simple structure, convenient cleaning and low noise, being the ideal equipment for coarse crushing.

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.
