The equipment needed to deal with modern minerals must have the following characteristics: (1) The amount of processing is large, and modern mineral processing objectively requires economies of scale to create benefits. (2) The effect on the fine grain size is remarkable, especially for the -01037mm grain size, and the original equipment can basically guarantee the recovery of the +01037mm grain size. (3) The enrichment is relatively high and the selection index is good. (4) Low power consumption. (5) The structure is simple and easy to maintain. Hydraulic classification equipment reselection cloud classifier tin box, divided mud bucket, heavy medium separation conical dense medium separator, vibrating chute heavy medium, heavy medium cyclones, heavy medium swash wheel sorter, jumping Jig, chute sorting machine, shaker, vortex sorting machine, photoelectric sorting machine, etc. Digital Welding Machine Equipment
MIG/MAG/TIG/MMA WELDING MACHINE:
The gas shielded welding machine actually has the characteristic of falling externally. It converts 220V and 380V AC into low-voltage direct current. Generally, the gas shielded welding machine can be divided into two types according to the type of output power supply, one is AC gas shielded welding machine; It is a DC gas shielded welding machine. The current conversion mode of the DC gas shielded welding machine is AC-DC-AC-DC. The gas shielded welding machine is composed of a power supply and a wire feeder. The shielding gas includes CO2, CO2 and argon mixed gas, and CO2 and helium mixed gas. do shielding gas

Features of gas shielded welding machine:
1 It has the advantages of light weight, small size, high efficiency and high reliability.
2 The welding current can output a rectangular pulse waveform to achieve spray transition and facilitate all-position welding.
3. It has automatic compensation function for grid voltage fluctuation.
4. It has automatic protection functions such as overvoltage, undervoltage, overcurrent and overheating.
5. Automatic compensation according to the cable length to ensure good welding performance for different cable lengths.
1. Welding may cause fire or explosion
1.1 Protect yourself and others from sparks and weldments during welding;
1.2 Be sure not to perform welding where there are combustible materials, because splashing sparks can easily cause combustion and cause a fire;
1.3 Be alert to fire, and place a fire extinguisher in the welding area;
1.4 Do not use a gas shielded welding machine to defrost the pipeline;
1.5 When the equipment is out of use, please unplug the welding cable from the welding output terminal;
1.6 Before welding, the on-site staff should hand over all flammable and explosive materials such as matches and lighters.
2. Fume and gas generated by welding will damage health
2.1 Keep good ventilation when welding indoors;
2.2 Do not perform welding near the site where there is degreasing, cleaning or spraying operations, because the heat and rays generated by the arc can react with the water vapor in the air to produce highly toxic and irritating gases.
3. Heating parts can cause severe burns
3.1 Do not directly touch the heating parts with your hands;
3.2 It can be welded with a welding torch after cooling.
4. Arc rays can burn eyes and skin
4.1 When welding or watching, you must wear a helmet with suitable filters to protect your face and eyes;
4.2 Use welding shields to protect bystanders from interference and stimulation from sparks and strong light.
