trailer mounted rotary screw air compressor for mines

The trailer-mounted rotary screw compressor is a high-efficiency air compressor designed for harsh working environments. It combines advanced screw compression technology and intelligent control system to ensure stable operation even under harsh conditions (such as high temperature, high cold, high dust and high altitude).

Description

This trailer mounted rotary screw air compressor is ideal for mining, hydropower station construction, highway construction, and more—delivering reliable compressed air for a wide range of pneumatic tools and equipment. Its robust design and advanced features ensure stable operation even under harsh and demanding conditions.

Working Principle of Trailer Mounted Rotary Screw Air Compressor

  1. Intake Stage: Air enters through the filter into the screw mainframe’s compression area.
  2. Compression Stage: Intermeshing screw rotors compress the air in two stages for higher efficiency and lower energy consumption.
  3. Exhaust Stage: High-pressure air is output through the exhaust line for pneumatic tools and equipment.

Additionally, the compressor features a silicone oil frequency conversion fan system, which intelligently adjusts fan speed based on working temperature—reducing noise, saving fuel, and adapting to varying workloads.

Main Features

  1. Adaptability to Harsh Environments: Operates reliably in high temperature, low temperature, high dust, and high altitude, ensuring stable air supply in mining, hydropower, highway construction, and more.
  2. High-Efficiency Compression System: Two-stage screw mainframe with large rotor and low speed provides excellent efficiency, low power consumption, and long-term durability (5 years or 10,000 hours warranty).
  3. Low Fuel Consumption & Intelligent Regulation: Stepless speed regulation system automatically adjusts engine speed according to air usage, minimizing fuel consumption and extending equipment life.
  4. Advanced Control System: Integrated control for protection, start/stop, loading, and more—plus global GPS and GRPS remote monitoring for real-time management and improved operational efficiency.
  5. High-Quality Engine Choices: Options include Dongfeng Cummins (for high intensity), and imported Volvo engines (for low fuel consumption, stability, and cold-start performance at high altitude).
  6. High-Efficiency Air Filter System: U.S. Frigidaire air filter with three-stage filtration protects the engine from dust and impurities, extends filter life, and reduces maintenance costs.
  7. Durable Fuel System: Large-capacity tank extends refueling intervals, while a three-stage fuel filter ensures long-term system stability and simple maintenance.
