Using and Operating Methods of Bona Drum Concrete Mixer

The followings are the operating principles of friction drum concrete mixer introduced by Bona Enterprise: the friction drum concrete mixer transits, which is driven by the friction of the rubber wheel, so the noise produced by the drum concrete mixer is small when the JZM series drum concrete mixer transits. Friction drum concrete mixer can be suitable for the civil engineering construction. However, the feeding methods adopted by friction drum concrete mixer produced by Bona Enterprise is lifting type. Therefore, when the charging hopper is rising, it is not allowed to work or go through under the charging hopper; lay some straw bags to the bottom of the foundation pit, which can be used as the pillow of hopper. When the hopper of the concrete mixer descends near to the ground, it is necessary to stop for a while and then make it descend to the ground, which can avoid the damage of hopper which is caused by the high descent speed; when the hopper of the friction drum concrete mixer need cleaning or it is necessary to check under the hopper, contact with the operating personnel well and begin to check the JZM series concrete mixer after locking the hopper with chains.
