Mexicali is located in the American border desert basin, the climate is hot, summer temperatures can reach 50 degrees, the winter temperature of about 5 degrees, annual precipitation is less than 260mm, the temperature difference between day and night, extreme arid climate, alluvial gold content is rich, the average tons of content about 1.5 grams. Because of this, the harsh environment led to a lot of gold projects failed, the reasons for the failure of mechanical equipment selection is unreasonable and equipment design defects.
Selection of 1. gold extraction equipment
Alluvial gold in such extreme circumstances should first consider the equipment continuous working ability and stability, suggested the use of equipment has the advantages of simple structure, no water separation equipment, such as: alluvial gold dry separation equipment
Sealing design of 2. equipment
Equipment want to work in high temperature, large temperature difference in the environment for a long time, first of all to ensure that the rotating parts of the lubrication and dust-proof, equipment transmission parts in addition to the use of oil seal, but also equipped with dust filter sealing, especially electrical appliances to use dust-proof explosion-proof appliances.
3. maintenance and repair of equipment
Selection of gold equipment for a long time in high temperature, dust environment operation, equipment maintenance is extremely important, under normal circumstances requires no 8 hours to add lubricating oil once, lubricating oil summer use molybdenum disulfide grease.
