Spiral classifier is a kind of equipment that uses the principle that solid particles of different sizes and specific gravities have different settling speeds in liquids for mechanical classification. It can filter the powder ground in the mill, then use the spiral blade to screw the coarse material into the mill feed port, and discharge the filtered fine material from the overflow pipe. Fine ore particles float in the water and overflow, and coarse ore particles sink to the bottom of the tank and are pushed to the upper part by the spiral to be discharged.

 

 

FG-500 spiral classifier belongs to high weir spiral classifier. Its overflow weir is higher than the bearing center of the lower end of the spiral shaft, but lower than the upper edge of the overflow end spiral, and has a certain settling area.

 

Suitable for coarse particle classification, and can obtain an overflow particle size greater than 100 mesh.

The body is welded with steel plates, which is sturdy and durable.

The water inlet and shaft head of the spiral shaft are made of cast iron sleeves, which are wear-resistant and durable.

The lifting device is divided into electric and manual types, which are flexible to operate.

 

The main technical parameters of FG-500 Spiral Classifier include spiral diameter, spiral speed, water tank length, motor power, etc., as follows:

 

Spiral diameter: 500mm

Spiral speed: usually in the range of 8~12.5r/min (the specific speed may vary depending on the manufacturer and custom requirements)

Water tank length: ≤4500mm (the specific length may vary depending on the manufacturer and custom requirements)

Motor power: The power of the transmission motor is generally 1.1kw (the specific power may vary depending on the manufacturer and custom requirements)

 

FG-500 Spiral Classifier is widely used in ore dressing plants to form a closed-loop cycle with ball mills to separate ore sand, or used in gravity ore dressing plants to classify ore sand and fine mud, and to grade the ore pulp in the metal ore dressing process, as well as desludging and dehydration in ore washing operations.

 

Price: The price of FG-500 spiral classifier varies depending on factors such as manufacturer, configuration, and customization requirements. Generally speaking, the equipment provided by professional manufacturers is relatively reasonably priced and of guaranteed quality.

Maintenance: In order to ensure the normal operation of the equipment and extend its service life, the FG-500 spiral classifier should be regularly maintained. This includes checking the wear of the spiral shaft, replacing worn parts, and cleaning the inside of the equipment. At the same time, attention should be paid to the operating status of the equipment during use, and faults should be discovered and handled in a timely manner.

 

FG-500 spiral classifier has a wide range of application scenarios and significant technical advantages. When selecting and using it, it should be customized and configured according to specific needs and actual conditions.
