Powder Coating Equipment

The powder coating and surface modification production line is also named as powder modification machine,powder surface modifying machine / equipment,mineral powder Coating machine / equipment, which is mainly responsible for three purposes, the first is mixture, the second is dispersion and third is surface modification to the powder via a specified melting modifier, resulting in a good combination. It can be divided into continuous modified production technology and batch ones, also there are two combinations of processes.

Basic technical requirements:

  • Dispersity of modifier is increased by means of dilution, emulsification and spray.
  • The material to be modified is fed into the coating machine, where the material will be mixed, dispersed and then coated by atomizing modifier sprayed by dosing pump and the the powder will be coated evenly and completely.
  • Control of system temperature and time is so regulated not only to meet the requirement for coating mechanism or modifier on technical conditions, but also to guarantee coating reaction or coating sufficiency.
  • The coordination of feeding material and modifier ensure the complete coating.
  • In conjunction of accessories ( depolymerizing machine or classifier), the product quality will be improved largely.

  • Batch-type operation.
  • Some materials has to be modified by silane coupling agent under high temperature and long time reaction.
  • Equipped with heating timing device, the modification temperature and time can be controlled.
  • Selectable ceramic liner is free from metal pollution.
  • The powder coating machine employs conic rotor and stator, the gap between them can be adjusted.
  • The highest linear speed of the rotor can reach 130 m/s.
  • The powder surface modification will be completed by high-speed impact, shear and friction of materials between stator and rotor driven by a motor.
  • It is very popular in China.
  • Realize powder surface modification by changing inner vortex with three rotating rotors.
  • Low investment and operation cost without any additional heating system.
  • Normally, this type is very popular in European and American markets.
  • Two rotors running in opposite direction, their linear speed can be up to 200m/s.
  • High-speed impact, shear and friction lead to full dispersion of materials and temperature rise, resulting in powder modification completely.

Coating mechanism

The basic principle of coating: obtain the highest coating rate or coating effect with the minimum coating material or cost;
Surface coating of mineral fillers, the main functions include dispersion, viscosity reduction, filling, and interface mechanics;
The most commonly used coating methods are: surface chemical coating method, coated coating method, mechanical force chemical coating method;
The coating methods mainly include: coating mechanism, modifier, coating process and equipment, process control, product testing and evaluation;
If the purpose, method and modifier of the coating are different, the process and equipment are also different.

Basic Process Requirements

  • The modifier uses dilution, emulsification, spray addition and other measures to improve the dispersion, preferably continuous spray or drip with the continuous feeding of the powder;
  • Precision metering and uniform feeding of modifier and materials to ensure the instantaneous precision of the ratio of the two, to achieve uniform and firm coating of the modifier on the surface of the powder, good controllability and stable product quality;
  • The regulation of the temperature and time of the system should meet the requirements of the coating mechanism or the modifier on the process conditions, and ensure the sufficiency of the coating reaction;
  • The equipment operating conditions are good;
  • The use of auxiliary equipment (deagglomerator or classifier), environmental factors (temperature, humidity), etc.
