Description

Desert permanent magnet automatic magnetic separator

technical field

The utility model belongs to the class of ore dressing machines, in particular to a machine for sorting out iron sand from desert gravel.

Background technique

There are abundant metal resources (such as iron sand, etc.) in the sand and gravel in the desert. There are many ways to recover metal from the sand and gravel. The most common way is to use panning equipment. This type of equipment consists of supports, pans, vibrating devices, power device, water supply device, feeding device and other components. A filter screen is installed at the bottom of the washing basin, and a layer of recycling cloth is arranged under the filter screen. The feeding device feeds the gravel into the pan, and at the same time, the water supply device injects water into the pan, and the pan vibrates under the drive of the vibrating device. Due to its high specific gravity, the heavy metals sink and pass through the filter screen, and finally settle on the recycling cloth, realizing the recovery of heavy metals. The main problems of this type of equipment are: wet operation, waste of water resources, pollution of the environment, low screening rate, low ability to process sand, and not suitable for iron ore recovery.
