Introductions

Double-end grinding machine is suitable for the departments of water conservancy and hydropower, geology and minerals, transportation, construction and so on in colleges and universities. Through the abrasive value determination to evaluate the anti-abrasive performance of not stone and artificial aggregate, to provide a basis for the auxiliary construction of different friction coefficient requirements of the road surface.

Structure composition

It is composed of machine base, grinding power head, variable speed transmission system, electric control device and other parts. The whole machine is easy to operate and has stable automatic feeding performance.

operating procedures

1.Clamp the sample block, pay attention to the symmetry of the two sides, close to the fixture.

2.Withdraw the two grinding heads, so that the specimen does not hit the grinding wheel when the table is in motion.

3.Install the protective cover and turn on the water switch.

4.Start the main power switch.

5.Start the grinding head button to make the grinding head rotate in the direction of the arrow, do not allow reversal.

6.Press the table button.

7.Manually feed the grinding head to grind, push the handle to the automatic position when automatic is needed, and grind the two grinding heads separately. Grind well pull the handle to the manual position and grind several times back and forth. Ensure the specimen finish.

8. Exit the grinding head after grinding.
