Pin Mill with Pin-Equipped Disks

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a novel design for a pinned disc mill (also known as a pin mill), where the discs are made from fine-grain ceramic or metal-ceramic composite materials with high strength, and the pins are made from metal-ceramic composites with high hardness. The invention aims to significantly improve wear resistance and operational durability, particularly under high mechanical loads and when processing abrasive materials. It further includes specific construction methods and choices of materials and coatings to maximize toughness, strength, and resistance to abrasion and impact.

Use CasesContent extracted from patent full text and abstract with AI.

• Ore processing and mineral refinement, especially for abrasive materials such as quartz-containing ores.
• Powder production in the chemical industry where wear-resistance and high-energy milling are critical.
• Food and pharmaceutical industries for grinding tasks that require high durability and precision.
• Pigment and dye manufacturing, particularly where abrasive components are processed.
• Recycling industries, for size reduction of hard or tough feedstocks.

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly increased wear resistance, enabling longer service life and reduced downtime for maintenance and part replacement.
• Ability to operate at higher mechanical loads and speeds without premature component failure.
• Enhanced toughness and hardness due to optimized composite materials and their tailored configurations (high-strength discs, high-hardness pins).
• Reduced risk of catastrophic failure (such as cracking or chipping of discs and pins) even under impact and abrasive conditions.
• Lower overall operational costs due to lower frequency of repairs and higher milling efficiency, especially in processing hard and abrasive materials.
• Improved energy efficiency in milling, as selective breakage and high-speed operation are better supported.

Patent Abstract

The invention relates to pinned disc mills comprising discs with pins. The pinned disc mills are characterized in particular by being usable in particular even under high mechanical loads. For this purpose, the discs consist of a fine-grain ceramic or a metal/ceramic composite material with a high degree of strength, and the pins consist of a metal/ceramic composite material with a high degree of hardness.
