HM Series Hammer Mill
HM Series Hammer Mill
Our hammer mill machine series — spanning industrial, small-scale, and lab-scale models (including dedicated lab hammer mills) — delivers fully hermetic, dust-free milling as a core advantage. Whether for large-batch production, on-site small-volume processing, or laboratory R&D, every model maintains airtight operation to eliminate dust leakage, ensuring material purity and a clean workflow.
Hammer mills, also known as a type of impact mill, have multiple alternative designations: universal pulverizers, knife mill, fine impact mills, centrifugal impact mills, comminuting mills, knife mills, as well as brand-specific terms like Pulva hammer mills, Mikro pulverizers, and Fitzmill.

Product Introduction


New Generation Of Technologically Advanced Hammer Mill Machine:


· Truly Hermetically Sealed, Dust-Free And Low-Temperature Grinding

· Modular Concept, Equivalent to the Swiss Frewitt Hammer Mill


Application Fields:

· Pharmaceutical Industry: 

Suitable for processing materials such as active pharmaceutical ingredients (APIs).

· Food Industry: 

Ideal for grinding sugar, icing sugar, salt, food additives, spices, and various grains, etc.

This hammer mill, when equipped with a vacuum feeder and a dust-free feeding station, becomes an excellent sugar grinder machine. It truly achieves airtight dust-free operation, low temperature rise, no material loss and high grinding efficiency.

· Chemical Industry: 

Applicable to most crystalline materials.


Product Advantages:

· Fully hermetically sealed and dust-free milling. The discharge can be hermetically connected to PE bags or stainless steel barrels. 

      A single advanced hammer mill machine = the main unit of an ordinary universal grinder+ cyclone+ dust collector+ fan+ electrical box.

· This knife mill has much lower grinding temperature rise than traditional grinders, offering water/air cooling/liquid nitrogen options.

· The effective area of the screen is larger, and the mesh hole rate is more than 30% higher than that of traditional screens.
· Direct drive of the motor with low noise. The rotational speed of HM-500 hammer mill is as high as 8000 rpm.
· The practical clamp connection design enables the cavity part of the equipment to be easily disassembled and separated, making it easier to clean and sterilize, which complies with the WIP and SIP standards.
· The cavity is polished, ensuring that there is no material deposition, and the cleaning is very convenient and simple.
· This fitzmill supports online cleaning and sterilization, and the machine head can withstand steam sterilization at 2.2 bar.
· This knife impact mill can be equipped with a hoist, and the height of the whole machine can be adjusted.
· The Garlock lip seal ring is easy to replace.
· The materials in contact with the materials are all made of 316L stainless steel, which fully complies with the GMP standards.
· The material yield is 100% without any loss.
