Discussion on the influencing factors of powder equipment

Powder equipment has a wide range of applications in many industries, such as metallurgy, decorative materials, chemical plants and coal mining. Its working efficiency and product quality are directly related to the production efficiency and market competitiveness of enterprises. Therefore, understanding the factors affecting the operating effect of the equipment is of great significance for optimising the production process and improving product quality.

Material characteristics are the primary factors affecting the effect of powder machinery. The hardness, humidity and brittleness of the material will have a significant impact on the grinding effect. Materials with high hardness, such as quartz stone, require greater grinding force and longer grinding time, which not only increases energy consumption, but also may lead to excessive wear and tear of the equipment. Materials with too high humidity are easy to clump in the mill, which affects the normal work of the grinding parts and reduces the grinding efficiency. And brittle materials are easier to break into fine powder during the grinding process, which is conducive to improving the grinding efficiency. Therefore, when selecting materials, its hardness, humidity and brittleness should be fully considered to ensure the smooth running of the grinding process.

Equipment parameters are also important factors affecting the effect of powder machinery. The rotational speed of the grinding roller (or disc) directly affects the grinding force and the residence time of the material in the grinding area. Too high rotational speed may lead to excessive grinding of materials into too fine a powder, increasing energy consumption; too low a rotational speed will not be able to effectively crush materials. The size of the gap between the grinding parts determines the degree of material crushing, too small a gap is easy to cause equipment clogging, too large a gap can not achieve the desired fineness of grinding. In addition, the fan air volume will also affect the effect of grinding, too much wind may not be fully ground material blowing out, too little wind can not be taken away in a timely manner after grinding fine powder. Therefore, in the selection of equipment, should fully consider its speed, clearance and fan air volume and other parameters to ensure the normal operation of the equipment and grinding effect.

The operating conditions also have an important impact on the effect of powder machinery. The feeding speed should be uniform and stable, too fast or too slow will affect the grinding effect. If the feeding speed is too fast, it will make the material pile up too much in the mill, affecting the grinding effect, and may even damage the equipment; too slow feeding will reduce the production efficiency. In addition, the continuous running time of the equipment will also affect the grinding effect, and long-time continuous operation may cause the equipment to heat up, affecting the performance and life of the components, which in turn affects the grinding accuracy. Therefore, in actual operation, the feeding speed and the continuous running time of the equipment should be strictly controlled to ensure the stability and high efficiency of the grinding process.

In addition to the above factors, the inter-particle adhesion force in the mixing process is also a key factor affecting the effect of powder machinery. The adhesion force of particles comes from a variety of factors such as van der Waals force, electrostatic effect, mechanical bonding, etc., and its size is related to the chemical composition of particles, particle size, morphology density and so on. The size of the adhesion force affects the degree of movement and dispersion of particles in the mixing process, thus affecting the mixing efficiency. Therefore, in the mixing process, the appropriate auxiliary material formulation and mixing equipment should be selected to regulate the adhesion force between particles and improve the mixing efficiency.

In summary, the effect of powder equipment is affected by a variety of factors, including material properties, equipment parameters, operating conditions and inter-particle adhesion force. In actual production, these factors should be considered comprehensively to optimise the production process and improve product quality and production efficiency.
