how much is yt28 Rock Drill in Zimbabwe
The YT28 pneumatic rock drill is a well-known piece of equipment in Zimbabwe’s mining, construction, and infrastructure sectors. It is favored for its robustness, simple design, and ability to handle complex rock conditions. However, for anyone looking to purchase this equipment in Zimbabwe, a straightforward question is: “How much does it cost?”
The answer is: In Zimbabwe, a brand new YT28 rock drill generally costs between US$800 and US$3,500 (or the equivalent in Zimbabwean dollars). However, this price range varies considerably, as different brands have different prices.
YT28 Rock Drill (Air Leg Type) Product Introduction
The YT28 rock drill is a pneumatic (air-powered) device widely used in rock drilling operations. It is a lightweight, efficient, medium-to-high-frequency rock drill, typically paired with an automatic telescopic air leg (such as the FY200B model) to form a hand-held air leg rock drill unit. It is a classic tool for drilling horizontal or inclined boreholes in medium-hard to hard rock.
Core Structure and Working Principle
Its core power comes from compressed air. When high-pressure air passes through the precise air distribution device inside the equipment, it drives the piston to perform high-speed reciprocating motion within the cylinder. The piston periodically impacts the shank rod (drill steel) at the rear. The impact energy is transmitted through the drill steel to the bit at the front, thereby breaking the rock. Simultaneously, during the intervals between impacts, another mechanism rotates the drill steel a certain angle, creating a new position for the next impact, enabling continuous drilling.
Main Product Features
- High Efficiency and Energy Saving: Utilizes a valveless air distribution system and an elastic support structure, resulting in high impact energy transfer efficiency and greater penetration speed for the same air consumption.
- Strong Environmental Adaptability: Compact structure and moderate weight make it particularly suitable for use in small to medium-sized cross-section tunnels, roadways, mining stops, and various infrastructure construction sites.
- High Reliability: Key components like the cylinder and piston are optimized in design and treated for wear resistance. With proper lubrication and maintenance, it offers good durability and a relatively low failure rate.
- Easy Operation and Maintenance: The overall structure is relatively simple, making it easy to disassemble, assemble, and maintain. It has relatively modest technical requirements for operators and maintenance personnel.
- Versatility: By更换 (replacing) drill steels and bits of different specifications and models, it can adapt to various borehole diameter and depth requirements. It is commonly used for drilling blasting holes, anchor holes, exploration sampling holes, etc.
Typical Application Scenarios
- Mining: Mining and roadway development in metal and non-metal mines.
- Civil Engineering: Excavation for highways, railway tunnels, and water conservancy projects.
- Construction: Rock foundation treatment, drilling in demolition of old structures.
- Quarrying: Dimension stone (like granite, marble) block extraction.
Usage Considerations
- Power Source: Must be connected to a stable, clean compressed air supply system, ensuring air pressure reaches the rated working pressure (typically around 0.5-0.7 MPa).
- Lubrication: Must use specialized rock drill oil and provide continuous lubrication via the设备自带 (built-in) oiler or an external inline lubricator. This is crucial for reducing internal wear and ensuring equipment lifespan.
- Supporting Tools: Must be used in coordination with a matching air leg, and drill steels/bits of suitable material and specification to achieve optimal performance and ensure safety.
