Product Introduction:
It is especially suitable for the ultra-fine crushing of crystalline or acicular particles, as well
as wet, greasy and viscous materials. For some materials, our pin mill machine can achieves
a finest discharge size down to D90 10μm, with single/dual rotor configurations available. We
can provide customized services based on your material characteristics and production requirements.
Working Principle:
This equipment utilizes a counter-rotating pin-disk impact grinding structure, combining
high-efficiency, high-speed impact with shearing and collision mechanisms. Material enters
the grinding zone between the rotor and stator pin disks via the feeding screw, where it is
pulverized through repeated impact, shearing, and friction. Product fineness can be precisely
controlled by adjusting the speed; the screenless design eliminates issues with screen clogging,
while a unique air-cooling structure effectively minimizes temperature rise, making it particularly
suitable for processing heat-sensitive materials. The different discharge fineness can be obtained
by adjusting the grinding speed.The higher speed, the finer the finished product. The lower the
speed, the coarser the finished product. The speed can be customized, but it cannot exceed the
maximum speed.

Equipment Features:
1. This machine supports low temperature cryogenic grinding by using liquid nitrogen.
2. The wide-chamber design facilitates efficient heat dissipation and prevents material adhesion
and accumulation;
it is particularly suitable for grinding materials with high oil or moisture content, as well as those
that are sticky or have
poor flowability.
3.The high-speed shear force generated by the relative high-speed operation of the needle bar
grinding discs on both
sides can achieve ultrafine grinding, and for certain materials, the finest can reach D90 5 um.
4. The screenless design makes it a relatively ideal choice for processing wet, high oil content, and
high viscosity materials.
This machine can be used in conjunction with a cyclone separator and a pulse dust collector to
achieve continuous and dust-free production.
