Heavy miner classification
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
mining machine is a tool for procing and mining bitcoin

According to the principle of action, the separation machine is divided into gravity separation machine, magnetic separator, flotation machine and special separation machine. Mineral processing machinery is also used in building materials, chemical instry, glass, ceramics and other instrial sectors. Mineral processing is the process of selecting useful minerals from the collected mineral raw materials according to the differences of physical properties, physicochemical properties and chemical properties of various minerals. The machinery that implements this process is called beneficiation machinery. According to the beneficiation process, beneficiation machinery is divided into crushing, grinding, screening, separation (separation) and dehydration machinery

gravity mineral processing machinery is a kind of equipment that uses the difference of density and particle size between ore particles and gangue to separate in moving medium, including jig, heavy medium concentrator and centrifugal concentrator
the jigging machine makes water flow in the water tank by means of diaphragm, piston or compressed air, so that the ore particles placed on the screen are stratified according to density and particle size under the action of pulsating water flow. The ore particles with high density pass through the bed rock layer on the screen and gather at the bottom of the water tank to become concentrate, which is discharged from the discharge port. Trapezoidal jigs, double chamber movable cone bottom jigs and compound vibration jigs are mainly used to separate metal ores; There are side drum jig and under screen air chamber jig for coal preparation. Dense medium concentrator uses suspension or heavy liquid as dense medium to separate ore particles from gangue. There are mainly heavy medium vibration chute, heavy medium swirler, inclined wheel heavy medium coal separator and vertical wheel heavy medium coal separator
centrifugal concentrator is a machine used to recover metal particles in fine slime, which is mainly composed of host and control mechanism. In the centrifugal force field proced by the high-speed rotation of the cone drum of the main engine, the heavy ore particles deposit on the drum wall and become the concentrate, while the light ore particles attach to the surface of the concentrate and are discharged from the drum and become the tailings under the action of the flow film (pulp flow)
magnetic separator is a kind of machine which uses the magnetic difference of various minerals to separate minerals with the help of magnetic force and mechanical force. The magnetic separator is composed of magnetic system, separation device, feeding and discharging device. There are many kinds of magnetic separators, such as permanent magnet cylinder magnetic separator, electromagnetic flat ring high intensity magnetic separator and high gradient high intensity magnetic separator
flotation machine is a kind of machine which uses the difference of physical and chemical properties of particle surface to separate fine minerals. The flotation agent is attached to the flotation machine. By means of compressed air or mechanical stirring, the ore particles that are not easy to be wetted by water are attached to the bubbles (positive flotation method), raised to the liquid level, and discharged as concentrate through the discharge device. The ore particles that are easy to be wetted by water are left in the tank and discharged as tailings
the concentrate from wet beneficiation needs to be dehydrated to separate the solid and liquid. Dehydration machinery can be divided into thickener, filter, centrifugal dehydrator and dryer. It mainly includes rotary drilling rig, rotary vertical shaft drilling rig, derrick (drill tower), winch, power engine (motor, diesel engine), mud pump and other equipment, as well as manipulator and pipe twisting machine and other ancillary equipment
