Characteristics of Cement Mortar Wear Resistance Testing Machine:

Automatic control digital display, with a speed error of less than1/4 turn. Easy to change load, equipped with a vacuum cleaning mechanism and an automatic parking alarm device. High precision, excellent quality, and good reliability.

Operation method of cement mortar wear resistance testing machine:

(1) Before starting up, check whether each transmission component rotates flexibly and whether there is any jamming phenomenon. Lubricating oil should be added to the machine base.
(2) Scrape the test piece (the molding and curing of the test piece shall be carried out according to the method specified in Article 6 of JC/T961-2005 (or the original JC/T 421-91) or the requirements of the test specifications) with the flat surface facing downwards, place it on the horizontal turntable of the wear-resistant machine, make positioning marks, and gently tighten it with a fixture.
(3) Set the pressure head load to 20ON (without adding weights), set the rotation speed on the electrical control box to 30 revolutions, adjust the suction device above the specimen, and then start pre grinding (pre grinding is to improve the contact between the specimen and the grinding head, remove the surface slurry, and the pre grinding rotation speed can change the strength and surface flatness of the specimen).
(4) After grinding, remove the specimen, clean the powder particles, weigh it with a balance, and use this amount as the original mass g1 of the specimen. Remove any residual particles and dust on the horizontal turntable.
(5) Place the pre ground test piece back on the horizontal turntable to its original installation position, flatten it, and secure it tightly. Determine the pressure head load according to the test requirements, then turn on the machine and grind it for 40 revolutions, remove the specimen, sweep away dust, and weigh g2
(6) Calculate the wear amount, accurate to 0.01kg/m2
