KY-200B Rotary Blast Hole Drilling Rig

Description
KY-200B rotary blast hole drilling rig is designed to drill big blast holes in large quarries and opencast mines. This blasthole drill has big capacity and high working efficiency. It is easy to operate and maintain. The delivery cycle of this rotary blast hole drilling rig is short, requiring 90~120 days. We can also customize this product for our customers, needing 90~150 days.

Characteristics
1. KY-200B blasthole drill uses low drilling frame, which can drill the hole at the depth of 17m whereas it should be added a rod in the middle period.
2. This rotary blast hole drilling rig is using 6 kv or 10 kv high voltage power supply.
3. The driving cab of this blasthole drill adopts double structure, which can prevent heat and keep warm. The driving cab is also equipped with air conditioner, electric heater, etc.
4. The caterpillar stents, balance beam, platform and drilling frame of this rotary blast hole drilling rig are made by low alloy steel. And their service life reaches 10 years.
5. AC frequency inverter, programmable controller (PLC) and HMI graphic operation terminal all adopt imported parts.
6. Rotation, elevation and walk of this blasthole drill are all driven by AC frequency conversion motor. They are controlled by three level inverter vector to realize stepless speed regulation.
7. Dust removal system of this rotary blast hole drilling rig uses compressed air injection type or pump water supply two kinds of wet dust removal system. The northern region utilizes water tank heating, water heating, etc. to prevent freeze.
8. The blasthole drill in open cast mining is leveled by four hydraulic jacks. It can work on the roughness of 400mm.
9. The hydraulic system manual multi-way valve and electro-hydraulic directional control valve adopts imported parts, and pneumatic components adopt Japan SMC products.
10. This rotary blast hole drilling rig is stable to operate with no need of maintenance at front 2000 hours.
