How to Distinguish Mining Cutting Picks from Engineering Cutting Picks?

Table of Contents

The cutting pick is an essential part of construction machinery. It serves as a tool for cutting, digging, and breaking rock formations. There are many types of cutting picks with a wide range of uses. Mining cutting picks and engineering cutting picks are two major categories, each with unique application scenarios and performance requirements.

The concept and types of mining cutting picks

Mining cutting picks are instrumental tools employed in mining machinery, including tunnel boring machines and shearers, to directly fracture rocks and dislodge coal. Their primary function is to cut through coal and rock, typically utilized in tandem with pick sleeves and pick seats.

Types of mining cutting picks

According to the shape of the division, mining cutting picks include conical picks and blade-shaped picks.

Conical picks are cutting picks with a conical pick head, and their geometric shape is tip-shaped or tapered.

Blade-shaped picks are cutting picks with a flat pick head and a geometric shape similar to the cutter body. Both of these picks are tools for mining machinery.

According to different types of mining machinery, mining picks include shearer picks, tunnel boring machine picks, continuous mining machine picks, bolter picks, etc. The most commonly used ones are shearer picks and tunnel-boring machine picks.

The shearer pick is the primary cutting tool on the drum of the underground shearer. It is installed on the drum with the pick sleeve and pick seat. It is one of the wearing parts of coal falling. Its performance directly affects the production capacity, power consumption, working stability, and service life of other related parts of the coal mining machinery.

The tunnel boring machine pick is the primary cutting tool on the cutting head of the tunnel boring machine. It is installed on the cutting head in conjunction with the pick seat. It is one of the wearing parts for tunnel excavation. Its performance directly affects the production capacity of the tunnel boring machine, power consumption, working stability, and the service life of other related parts.

Concepts and types of engineering cutting picks

Engineering cutting picks are picks used in highway engineering. The application environment for engineering picks differs significantly from that of mining picks. While the former is utilized on road surfaces, the latter operates underground. Additionally, engineering picks are accessories for construction machinery, while mining picks are accessories for mining machinery.

Types of engineering cutting picks

milling machine picks

Depending on the type of machinery, engineering picks include rotary excavator picks, milling machine picks, etc.

The rotary excavator pick is a cutting tool specifically designed for use in a rotary excavator, mounted on the drill bit of the equipment. There are two types of pick seats available: square and round. Notably, round pick seats exhibit superior wear resistance, albeit at a higher cost compared to square pick seats.

A milling pick is a cutting tool specifically used for road milling. It removes impurities, damaged pavement, and irregular parts from the road surface through rotational cutting and crushing work, laying the foundation for subsequent repair work.

Distinguish between mining cutting picks and engineering cutting picks from practical applications

cutting picks
  • Application fields: mining cutting picks are mainly used in the mining industry, while engineering cutting picks are widely applicable in various engineering construction fields.
  • Usage environment: mining cutting picks are usually used in underground mines or open pit mines and other complex environments, while engineering cutting picks are used on the ground, outdoors, and in environmental conditions.
  • Cutting objects: mining cutting picks are primarily employed to cut through coal seams and rocks of varying hardness, whereas engineering picks are used for cutting diverse materials, including concrete, rocks, and others.
  • Performance requirements: mining cutting picks require high strength, wear resistance, and impact resistance, while engineering cutting picks pay more attention to cutting efficiency and economy.
  • Maintenance: due to the differences in usage environment and performance requirements, there are some differences in the maintenance and upkeep of mining cutting picks and engineering cutting picks.

In summary, there are significant differences in application scenarios between mining cutting picks and engineering cutting picks. Clarifying the characteristics and differences between the two will help to select the appropriate pick type in practical applications and improve work efficiency and safety. With the continuous advancement of technology and the diversified development of application requirements, the pick industry will present more diverse product types and technological innovations in the future.
