Technical parameters
1. Weight of the hammer: 6670±10g
2 cam lift: 50 mm
3. Hammering times: 3 times
4. Work applied to the specimen: 10 joules
5. Compacting rate range: 20~70%
This machine simulates the principle of compacting sand during molding, and applies 10 joules of work to the sand to be tested in various specimen molds to prepare the required standard process specimens. Then the strength of the sand is measured on the strength tester; the air permeability of the sand is measured on the air permeability tester; at the same time, the compacting rate of the sand can be directly measured by this machine.
