The pin rod fine grinding mill is suitable for the crushing and processing of medium and low hardness materials in industries such as chemicals, dyes, additives, feed, food, pharmaceuticals, and non-metallic minerals. It offers advantages such as high output, fine particle size, low noise, low energy consumption, simple maintenance, and convenient installation.

Needle-rod type fine grinderThe material enters the crushing chamber from the hopper via a screw conveyor, where it is crushed through impact, shearing, and grinding between the high-speed rotating blades (pin rods) and the fixed toothed ring. The powder is discharged from the chamber through a screen, and the particle size is obtained by replacing screens with different aperture sizes. It is used for crystalline and fragile materials. The product fineness is <50μm, and different product fineness can be achieved by adjusting the rotor speed. Changing the number and arrangement of pin rods will also affect the product fineness.
Needle-rod type fine grinderMain advantages:
Needle-rod type fine grinderDesigned based on international advanced crushing technology research, the structure is novel, reasonable, simple, and compact, with small size, high efficiency, attractive appearance, and easy replacement of wear parts.
Precisely select the clearance between the rotor and stator, along with the corresponding rotor tip speed, to keep the crushing process in an **optimal state**.Needle-rod crusherGood sealing performance, with a built-in labyrinth seal and an "O"-ring seal on the machine door, ensuring no dust leakage. The crushing chamber has ample discharge space. Due to the high-speed rotation of the rotor, a large amount of air is drawn in, providing a self-cooling function, making it suitable for crushing certain heat-sensitive materials.
The bearing system uses imported high-speed precision bearings, and the rotor undergoes overall dynamic balancing to ensure smooth operation, low vibration, and low noise. The pipeline connection adopts a quick-release structure, allowing for fast and convenient disassembly, assembly, and cleaning.
Equipped with a cyclone separator and dust collector, the production process is free from dust dispersion: the dust collection bag effectively captures fine powder in the airflow, ensuring that exhaust emissions meet clean and environmental protection requirements.
The fine powder retained by the dust collection bag can be effectively recovered, reducing the material loss rate.
