Grinding mill

Description

The industrial pin mill (also known as a universal mill, turbo mill, and impact mill) is a one pass grinding equipment ideal for achieving the micronization of bulk materials and powdered products. Common applications involve the fine grinding of sugar, salt, sodium bicarb, etc. The average achievable particle size range of the pin mill is around a d50 of 80 microns. Results can vary depending on the material, rates, feed, etc.

Made from mild steel, stainless steel 304L or 316L
4 models according to required feed rates and capacities: 160, 315, 500 and 630

Industrial mill range

The Poly-Mill industrial grinder is the ideal solution for milling a wide range of bulk products. Each milling system requires a specific solution according to the expected particle size range. The Poly-Mill grinder can be fitted with several easily interchangeable milling tools to adapt to the specific needs of each application. Custom designs for CIP milling requirements and turn-key solutions available with our experienced engineering staff capabilities.

FOOD PROCESSING APPLICATION

Operating sequence

The feed of bulk materials is supplied to the center of the grinding medium (pin discs). A magnetic separator is integrated in the feed inlet leading into the grinding chamber for protection of the mill. The one pass mill process is conducted via the impact milling medium, which are rows of pins concentrically mounted on rotary discs. The RPM of the discs are adjustable by variable speed controls (can be supplied in addition to the mill) which can produce finer or coarser grinds. The particle size of the powder output is determined by three main factors:

1 - Rotation speed
2 - Number and shape of the pins
3 - Air flow rate

Applications:

Food processing
Spices
Pharmaceuticals
Animal feed
Chemicals
Wood and plywood
Mineral powders
Plastics

Equipment advantages

- Design configuration according to available space

- Easy access to grinding chamber via swing-away door and interchangeable grinding media

- Reinforced feed inlet design ensuring high rotation velocity and dust tight sealing

- Ultra fine particle size milling

- Adjustable quantities of pin rows for more or less impact surfaces
