Core-Pulling Type Self-Cleaning Magnetic Separator
The core-pulling type self-cleaning magnetic separator mainly consists of a reduction motor,a casing assembly, permanent magnetic bars,a three-way valve,and a pneumatic control system.It operates with a top feed and bottom discharge design.During operation,the permanent magnetic bars are inserted into the casing assembly,creating a strong magnetic field around the casing.The motor rotates,driving the entire setofmagnetic bars,allowing the casing to come into full contact with the material.Magnetic foreign objects are attracted and adhere to the casing. Demagnetized material,due to gravity or negative pressure,moves downward into the three-way valve's discharge outlet.
For demagnetization,the motor stops,and the three-way valve's valve plate is opened to the slag discharge end. A dual-cylinder mechanism actuates the permanent magnetic bars to separate from within the casing,causing the casing to lose its magnetic attraction and the magnetic foreign objects to falloff.Meanwhile,the motor rotates to shake offany residual magnetic foreign objects from the casing.This equipment is suitable for low-moisture,dry powders and granular materials.
The pulp magnetic separator is a specialized piece of equipment designed to remove magnetic impurities from a medium in the form of a pulp or slurry.The fluid medium is pumped into the pipeline by a fluid pump and enters the chamber through the lower pipeline.The design features a tangential water flow and a special rotating paddle structure,which allows the material and the magnetic bar assembly to self-rotate and mix thoroughly within the chamber.Magnetic impurities are attracted and held by the built-in high-strength magnetic bars,while the cleaned fluid passes through the upper pipeline to the next process.
The model 300 pulp magnetic separator can have up to 18 buit-in magnetic bars,with a surface magnetism of up to 14,000 Gauss(Gs),and can achieve demagnetization eficiency of over 90%with a throughput of 50 cubic meters per hour(m³/h).Depending on the application requirements,the equipment can be available in fully automatic and semi-automatic models.The main difference between the two lies in whether the demagnetization action requires manual intervention.The fully automatic model utilizes a cylinder and a scraper to achieve full process automation.
Automatic Suction Gun The automatic suction gun is composed of four main parts:a bracket (including a hopper positioning frame),an XYZ slide platform,the suction gun itself,and a control system.It can be equipped with weighing devices,and the suction speed can be adjusted according to the capacity of the vacuum feeding device to automatically control the walking speed of the suction gun and the thickness of the single suction layer, matching the speed of the vacuum feeding device.The automatic suction gun is interlocked with the vacuum feeding device,replacing the manual feeding process.It is suitable for environments with requirements for heavy pollution, high-temperature,or low-temperature conditions.
The pin disc mill is an integrated piece of equipment that combines mechanical and air-swept grinding methods.It features a horizontal design with a unique pin disc structure.Material is forced through the toothed nest and then subjected to high-speedshearing by the conical grinding bars of the rotor and the stator grinding blocks.By adjusting the rotor speed,the mill can process various raw materials to different fineness levels.It is also capable of dispersing,mixing,and surface coating the material.
A distinctive feature of the pin disc mill is the rotor's high-speed rotation,which,combined with the stator's toothed nest,creates an orderly air vortex within the grinding chamber.This allows the material to be thoroughly dispersed through the vortex,where it is sheared and impacted by the rotor and stator,ensuring a uniform surface coating on the powder particles.
Scraper-Type Self-Cleaning Magnetic Separator
The scraper-type self-cleaning magnetic separator mainly consists of a reduction motor,permanent magnetic bars,a three-way valve,and a pneumatic control system.Itoperates with a top feed and bottom discharge design. During operation,the motordrives the permanent magnetic bars to rotate,allowing the material to come into full contact with the magnetic bars.Magnetic foreign objects within the material are attracted to and adhere to the surface of the magnetic bars.Once the material is demagnetized,it is conveyed downward by gravity or negative pressure to the discharge outlet of the three-way valve.For demagnetization,the motor stops,and the three-way valve opens to the slag discharge end by means of a valve plate.A pneumatic cylinderactuates the demagnetization scraper to push the magnetic foreign objects,which are adhered to the surface of the magnetic bars,into the non- magnetic zone of the bars,where they falloff due to gravity into the slag discharge end.This equipment is suitable for use with moist,sticky powders and granular materials.
Pre-drying Machine The pre-drying machine is a device designed for the drying and dispersion of water-containing filter cakes.Within the system,it uses negative pressure to draw hot air in from the feed end.The water-containing material,upon entering the pre-drying machine,is gradually dried as it comes into contact with the hot air through the actions of the machine's raking teeth,which stir and lift the material.In the latter part of the drying process,the now partiallydried material is further dispersed into smaller pieces by the rotating raking teeth and then conveyed to the subsequent process by negative pressure air.The pre-drying machine serves as a pre- treatment device before the crushing process,with a maximum capacity of 5,000 kg/h.To meet the diverse demands of production line capacities,multiple models are available for selection.
