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.
The electric heating air furnace features a hot air chamber with interior lining materials made of stainless steel grades 304 or 310,which offer good corrosion resistance and durability.The heating elements can be made from materials such as aluminum,Q235 steel,seamless S304 tubes,or fin tubes,which are designed to efficiently transfer heat to the air.The furnace is insulated with alumina-silicate fiber,which provides effective thermal insulation and energy efficiency.It is equipped with an automatic temperature control system that can be interfaced with the system's PLC for automated temperature regulation.
The vacuum feeder operates by introducing material from the top and discharging it from the bottom of a storage hopper (cone hopper).It consists of three main parts:a filtration chamber,a clean air chamber,and a storage hopper (cone hopper).Dry powdery materials with good flow characteristics are conveyed into the vacuum feeder by a negative pressure system through the feed inlet.The material is separated from the air as it passes through the filter element,and then it falls by gravity into the storage hopper.With the aid of a pneumatic hammer or vibrator and air assistance in the storage hopper (cone hopper),the material is smoothly discharged from the outlet.Meanwhile,the negative pressure air,after being filtered through the filterelement,is exhausted from the clean air chamber,achieving the purpose of material transportation.Additionally,the storage hopper (cone hopper)is equipped with a high-level sensor to prevent blockages that could occur if the material is not discharged promptly.
Twin-Shaft Mixer Feeder (for Dry and Wet Materials)The twin-shaft mixer feeder is composed of a pair of rotating shafts,a housing,and a motor assembly.The driving motor powers the rotation of the shafts,which enables the continuous mixing of both dry and wet materials.This process enhances the solid content of the materials,facilitating their subsequent treatment or processing.
