Vertical Needle Impact Mill Spare Parts - Rotor

The rotor plate of a pin impact mill (also called the rotor disc or grinding disc) is the core rotating component on which the moving pins are installed and is directly driven by the main shaft. It works with the stator plate to form the crushing chamber and is the key carrier for achieving high-speed impact grinding.

Grinding-Chamber Liner

Protective inner-wall wear-plate for ultrafine-mill grinding chambers. Mounted inside mill housing, it is a vulnerable wear-resistant spare-part and works in conjunction with grinding discs.

Mill Screen

Core classification consumable for modified-starch ultrafine mills, fitted inside the grinding chamber. After impact and grinding, particles of qualified size pass through the screen for discharge, while over-size coarse material remains inside the chamber for re-grinding. It controls final particle-size of finished modified-starch powder.

V-Belt Set

Transmission consumable for ultrafine mills. Installed between motor pulley and ultrafine-mill main-unit pulley. It transmits torque via friction and drives high-speed rotation of the grinding disc to complete ultrafine pulverization of modified-starch feedstock.

Crusher Grinding Disc

The disc face carries radial crushing teeth, with coarse crushing teeth on the inner ring and fine grinding teeth on the outer ring. Material is fed from the center and progressively sheared and ground outwards. The gap between the moving and stationary discs determines the fineness of the finished product and can be adjusted manually. It is widely used for micro-powdering of rice protein, chemicals, and traditional Chinese medicine.

Micronizer Spare Parts - Hammer Head

The hammer is the core wear part of the micro powder machine.

Micronizer Spare Parts - Hammer Plate

The hammer plate is the core base component of the micro-powder mill rotor, mounted on the main shaft of the equipment, and serves as the framework of the entire crushing rotor.

Vertical Needle Impact Mill - Grinding Needle

The grinding needle is the core working component in a needle impact mill that directly realizes material crushing. It relies on high-speed rotation to impact, shear, and grind the material, achieving ultrafine pulverization. It is generally divided into dynamic needles and static needles.

Vertical Needle Impact Mill Spare Part - Spindle

The spindle is the core rotating component of the vertical needle-type impact mill, responsible for transmitting power, supporting the rotor, and operating stably under high speed, heavy load, and impact conditions.

Sieve Plate (Perforated / Woven)

Internal sieve plate for crusher, controls discharge particle size of crushed material.

Crusher Hammer Blade

Core striking component of hammer crusher; crushes corn by high‑speed impact.
