The classifier disc cell mill is divided into three parts:the premix chamber,the grinding chamber,and the classifier.Material is drawn into the premix chamber by an induced draft fan for preliminary mixing,ensuring that the material enters the grinding chamber in a uniform fluidized state.The main component of the grinding chamber is a vertically installed multi-stage rotor,which consists of multiple discs sandwiched between two support disc plates mounted on the main shaft.
The interior wall of the grinding chamber is lined with vertical grooves that are 6 to 8 millimeters deep,and the gap between the rotor discs and the lining strips is 2 to 5 millimeters.When the rotor spins at high speed,it generates turbulent airlow in a"nested"pattern.The airlow pressure,friction,and shearing forces,along with a chamber wind speed of 30 meters per second and a rotor linear speed that can reach up to 120 meters per second,quickly reduce the material intoultra-fine powder.
After grinding,the material is carried by the airflow into the classifier section.The entire system's airflow and the classifier can be adjusted according to the particle size requirements.Larger particles are separated by the classifier wheel and,under the influence of gravity,fallback into the grinding chamber for further grinding until the desired particle size is achieved.
The pin disc mill with twin rotor is an integrated piece of equipment that combines both mechanical and air- swept grinding methods,featuring a horizontal design.Inside the chamber,there are two layers of disc rotors and toothed stators that work together.The unique disc rotors,when spinning at high speed,create an orderly air vortex with the toothed stators.This vortex causes the material within the grinding chamber to be sheared and impacted by the toothed nests and discs,quickly reducing the material into ultra-fine powder.The interaction between the disc rotors and the toothed stators ensures a thorough grinding process,which guarantees an even distribution of particle sizes in the finished powder.
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.
