NBJ-II Slake Durability Apparatus （Slake Durability Apparatus）

Instruction

The NBJ-II slake durability Apparatus is mainly used to determine the durable disintegration index of rocks. It can test the durability of rocks that can resist disintegration due to the influence of weather. The device rotates two drum-shaped sample boxes at a speed of 20 revolutions per minute through a motor fixed on the bottom of the device. The drum-shaped sample box is mounted on a bearing coated with lubricant, and there is no resistance when rotating. The drum-shaped sample box is made of corrosion-resistant materials and is equipped with two water tanks. It is widely used in various universities, scientific research institutes, test centers, etc. to determine clay rocks and weathered rocks, etc.
