The first change of gearbox oil is after 100 hours of mixer operation.From the second time oil should be replaced every 1500 hours,Check regularly whether the oil deterioration,if found that the deterioration of oil,emulsification and other phenomena.Please timely replace oil,so as not to cause damage to the reducer

　　The standard mixer adopts well-known domestic brands,or international brands such as ABB and Siemens can be used according to customer requirements,and the price will be different

　　The standard mixer USES high chromium alloy liner and blade,and can also be customized according to different material requirements.

　　According to the calculation of mixing C30 ready-mixed concrete,the service life of the blade is 30,000 times and the life of the lining plate is 40,000 times

After using 200 squares, tighten the mixing arm and blade bolts in time, check the wear of the mixing arm blades every week to ensure the gap between the blades and the lining plate is 3-5mm. When the blades cannot be adjusted, replace the blades in time, and clean the mixing drums in time. Accumulate materials, back and forth to close the door, to ensure unloading unblocked.

Check the mixer liner, blade and powder discharge port for accumulation;

Check the mixer running time and the amount of each mixing, total production.

Check the sealing gap of the discharge door for each shift and adjust it; if it cannot be adjusted or leaked, replace it in time.
