The TMI Chip Class™ is a robust laboratory and/or production tool designed as a trouble-free chip classification
system. A minimum of moving parts and carefully selected components provides the most reliable chip classification
system available on the market today. The design is based on the original US patent developed by one of the world’s
largest pulp and paper makers. The TMI Chip Class™ measures the size distribution and relative quantity of chip size
fractions for mechanical and chemical wood chips.
Special trays are also available to meet most hole and bar dimension requirements making the Chip Class a versatile
testing tool for measuring a variety of other materials requiring size classification.

OPERATION

The test operation for measuring chip size distribution is based on several international standards, TAPPI UM 21
Sieve analysis of pulpwood chips and SCAN-CM 40:01 Wood chips for pulp production-size distribution are the most
popular. Other methods include the Scan 47:92 which specifies bar/slots for determination of thickness of chips, the
Williams and the WPFL(Hartler/Hatton) classification series.
The TMI Chip Class™ is capable of meeting almost any method when equipped with the proper set of trays and
appropriate hole diameters specified in the corresponding standards. The TAPPI standard is based on a sieve system
consisting of 4 trays and the Scan method is based on a 5-tray system.
To start a test, distribute 4-10 liters of chips on the top screen and press start. An automatic timer will start the
shaking mechanism and shake the stack for approximately 10 minutes. After completion, remove and weigh the
chips in each tray. Measure the total weight for each tray and calculate the chip percentage per tray.
