According to the power used, gold mining vessels can be mainly divided into electric, steam, internal combustion engine and water wheel.
Electric gold mining vessels are divided into onshore power supply and onboard power supply. When power is supplied from the shore, the rubber insulated three-wire cable is erected by a float and sent to the ship. Its main advantages are to reduce the load of the ship, reduce the area of ​​the ship, and easy to operate. However, in large rivers, especially when the river is rushing or there is often wood floating, laying the cable is very difficult, so the ship is powered. At present, in order to avoid the installation of huge boilers and steam equipment on ships, it is generally preferred to use electric gold mining vessels.
Steam-type gold mining vessels are not widely used and are generally limited to the mining of small sand deposits in the fuel supply area.
Power Equipment engine type gold dredger coal into gas and diesel engines two kinds. When using a gas engine, each axis consumes 0.42 to 0.6 kg of anthracite or 0.53 to 0.60 kg of charcoal and 6.06 liters of water per kilowatt-hour. In general, the cost of a gold mining vessel with a gas engine is lower than that of a steam gold mining vessel. Diesel engines occupy less space than gas engines, and consume about 0.31 kilograms of diesel per kilowatt-hour per axis.
The power of a water wheel type gold mining vessel is supplied by wheels that are impulsive to water flow. The water wheel is installed on one or both sides of the ship. The normal operation of the gold mining vessel is guaranteed when the water flow rate is 5.6 km/h. The advantage of the water wheel type gold mining ship is that it uses natural power and the infrastructure cost is low. However, its process conditions are unstable due to the influence of the water flow rate.
Wood pellet complete production line is euipment for making the wood log/wood chips/sawdust/wood shaving/rice husk/stalk/grass...raw material into fuel pellets, Main process: Wood Chipper --hammer mill--biomass dryer--Biomass Pellet Machine--pellet cooler--Pellet Packing Machine.
Wood chipper: make the wood log/wood branches/wood blocks/bamboo... into smaller chips. Finished products: 20-50cm.
Hammer Mill/Crusher: crush the wood chips/wood shaving/small blocks/grass/stalk...to 6-8mm powder. Finished products: 6-8mm.
Rotary Dryer: dry raw material into suitable moisture to produce high-level pellets. Finished moisture: 10-15%
Wood Pellet Machine: press crushed and dry sawdust/rice husk/straw/grass... into pellets. Finished pellets: 6/8/10mm.(Asian Market standard: 8mm; European Market standard: 6mm)
Cooling Machine: cool high-temperature pellets before packing.
Reason: the finished pellets are very hot and realease moisture as they leave the pellet machine. This section can ensure to generate smooth pellets.
Packing Machine: pack pellets into 20-50kg/bag or 1 ton bag. Advantage: easily to be transported to final users' site.
