Title:
TOOTH PLATE OF CRUSHER
Document Type and Number:
Japanese Patent JP2525310
Kind Code:
B2
Abstract:
PURPOSE: To form a groove in a short time and form a granular product into a cubic shape.
CONSTITUTION: A member 4 having high abrasion resistance and a member 6 having low abrasion resistance are provided at least on either or both of a pair of tooth plates parallelly and alternately in a direction normal to the thickness direction of the tooth plates on effectively thick-walled portions thereof, and a member 5 is embedded in the member 6, where the member 5 has a lower height than the member 6 and has intermediate abrasion resistance. As a result, differences in abrasion resistance between adjacent members 4, 6 can be made large, so that the member 6 having low abrasion resistance covering the upper part of the member 5 having intermediate abrasion resistance is worn in an initial stage of use and an edge of a groove formed by the wear can be maintained sharply until a final stage of use.
