Permanent Magnet Dry Roll Magnetic Separator

Permanent Magnet Dry Roll Magnetic Separator

Product Overview
Permanent Magnetic Dry Roll Magnetic Separator is a new generation of high-efficiency magnetic separation equipment developed by our company, which adopts high-performance neodymium iron boron rare-earth permanent magnetic material, and can be flexibly configured with 1-5 rolls according to customers' requirements, and the magnetic field strength of each roll can be independently customized (800-16000 gauss). This equipment is specially designed for dry sorting of various magnetic minerals, with flexible configuration, accurate sorting, energy saving and high efficiency, etc. It can meet the individual needs of mineral sorting in different scale of processing plants.

Core Advantages

• Modularized magnetic roller system
  Optional number of rolls: support 1-5 rolls free combination to meet the needs of different sorting stages;
  Magnetic field customization: each roll can be independently configured 800-16000 gauss magnetic field strength;
  Flexible layout: the magnetic rollers can be set to rotate in the same direction or in the opposite direction to optimize the sorting effect.

• Intelligent sorting control
  Equipped with frequency conversion speed control system;
  Digital magnetic field strength display and adjustment;
  Automatic matching system for feeding speed.

• High-efficiency energy-saving design
  Energy consumption of tons of ore is as low as 0.15-0.5 degrees of electricity;
  No dust removal water consumption;
  Closed structure reduces dust spillage.

Technical Parameters

Typical configuration program

• Single-roller basic type
  Applicable scenario: primary sorting, iron removal operation;
  Configuration suggestion: customized according to mineral characteristics;
  Processing capacity: 1-5t/h.

• Double-roll standard type
  Configuration scheme: front roll roughing + back roll selecting;
  Applicable minerals: ilmenite, manganese ore, etc.

• Three-roll fine type
  Configuration scheme: 1 roll de-magnetization → 2 roll main sorting → 3 roll fine sweeping;
  Application examples: zircon sand three-stage purification.

• Five-roller specialized type
  Configuration features: gradient magnetic field design;
  Specialized application: multi-stage sorting of rare earth ore.

V. Working Principle
The materials are evenly distributed on the surface of the first roller through the vibrating feeder, the magnetic minerals are adsorbed under the magnetic field and rotate with the magnetic roller to the unloading area; the non-magnetic materials are thrown down under the centrifugal force. When the configuration of multiple rollers, the materials pass through the magnetic rollers in order to carry out multi-stage sorting, and each roller can be set with different magnetic field strength and rotation direction according to the needs to realize precise separation.

Operation Guide

• Parameter setting
  Set the magnetic field strength of each roller according to the mineral characteristics;
  Adjust the rotating speed of magnetic rollers;
  Setting suitable feeding speed.

• Operation monitoring
  Observe the sorting effect of each roll;
  Regularly check the concentrate grade;
  Monitor the operating temperature of the equipment.

• Maintenance points
  Clean the surface of magnetic rollers daily;
  Check the performance of the magnetic system monthly;
  Replacing bearing grease quarterly.
