Abstract

The invention discloses a deep sea cobalt crust shattering method and a device thereof; the method adopts mechanical tooth and water jet to shatter deep sea cobalt crust in a combining way, and high pressure water flow is jetted to impact a stress area of the deep sea cobalt crust to assist to shatter the deep sea cobalt crust when mechanical force is applied by the mechanical tooth to shatter the deep sea cobalt crust. The device comprises a mechanical crushing device and a water injector which are used for acting on the deep sea cobalt crust together; the water injector includes a water tank, a high pressure pump, a first valve, an energy accumulator, a second valve, a controller and a nozzle; wherein, the water tank, the high pressure pump and a check valve are sequentially connected with each other in series and then are connected with the energy accumulator which is also connected with the nozzle by the second valve. The invention can reduce the impact load acting on a shattering head in the crushing process of the cobalt crust, and improve the travelling speed of a mining machine.

Description

technical field [0001] The invention relates to a rock crushing method and device, in particular to a deep sea cobalt crust crushing method and device. Background technique [0002] Deep-sea cobalt crust is an important deep-sea mineral resource. With the depletion of land resources, the development of deep sea resources has become an international trend. The mining of deep-sea cobalt crusts is a huge and complex task, involving many key technologies such as cobalt crust crushing, ore collection, and mine lifting, among which the crushing technology is one of the basic technologies. Its main task It is to peel off the cobalt crust from the bedrock and break it into particles of a certain size range. [0003] Most of the existing cobalt crust crushing methods adopt mechanical crushing methods, and the cobalt crust is crushed by knives and picks. Studies have shown that the crushing head of the purely mechanical crushing method will be subject to strong impact loads during ...
