​Grinding Dust Collector

    Grinding dust collector is a dust removal equipment suitable for dust treatment in grinding workshops, often referred to as a grinding mill dust collector. It adopts compartmental off-line cleaning, featuring high dust removal efficiency, low secondary dust re-entrainment, and effectively reduced energy consumption. The coordinated operation of cartridges and pulse valves extends the service life of filters and fans, significantly lowering equipment operation and maintenance costs.

The equipment can be equipped with a PLC control system to realize automatic cleaning, ash discharge, automatic temperature control, and over-temperature alarm functions. In addition, alarm and control functions can be configured with temperature, level, and other sensors according to user requirements.

    By using long filter cartridges, the equipment reduces floor space under the same processing capacity. The cartridge ports adopt a spring tension structure, enabling easy installation and removal with excellent sealing performance.

The grinding mill dust collector uses an optimized air intake structure, allowing coarse high-temperature particles to fall directly into the dust hopper, effectively protecting the filter cartridges. Maintenance and filter bag replacement can be performed in individual compartments without stopping the system fan or interrupting normal operation, greatly improving work efficiency. The casing is airtight and tested by kerosene leak detection to ensure reliable sealing performance.

Core Working Principle

• Dust Collection: The equipment is started before grinding operations. The negative-pressure exhaust fan creates a negative-pressure field. Dust generated during grinding is captured at close range through a dust hood or telescopic dust suction arm, preventing dust from spreading into the workshop.

• Airflow Conveying: The captured dust enters the equipment cabinet or main unit through the dust suction pipeline along with the negative-pressure airflow. Large-particle dust settles into the dust collection box or hopper under gravity, completing pre-filtration.

• Core Filtration: The airflow containing fine dust further passes through special grinding-purpose filter cartridges or bags. Dust is intercepted by the filter fibers, achieving thorough gas-dust separation. The filtered, clean air enters the clean air chamber.

• Up-to-Standard Discharge. Clean air in the clean air chamber is discharged through the air outlet (internal workshop circulation or outdoor up-to-standard discharge, designed as required), completing the dust filtration process.

• Pulse Cleaning: As the dust layer on the filter elements builds up over time, the equipment's operating resistance reaches the set threshold. The pulse cleaning system activates automatically. Compressed air is injected into the filter elements at high speed through the jet pipes, causing instantaneous expansion and vibration, so that dust on the surface quickly falls into the dust collection box or hopper.

• Dust Removal: When dust accumulates to a certain level in the dust collection box or hopper, the dust is removed uniformly by shutting down the equipment (mobile type) or opening the ash discharge valve (fixed type). The filter elements restore their filtration capacity, allowing continuous and cyclic operation of the equipment.
