Product Detail

描述

Overview

The Circular Crusher Valve is designed for crushing, discharging, air locking, and anti-blocking of caked bulk materials at the outlet of silos and conveying systems. It features a cylindrical housing with circular inlet and outlet flanges, allowing direct connection to round silos, discharge pipes, chutes, and pneumatic conveying lines.

The equipment is driven by a motor and reducer to rotate the crushing rotor at low speed and high torque. Material entering the valve body is impacted, compressed, and sheared by the crushing claws. Qualified fine material passes through the internal screen ring, while larger lumps continue to be crushed, ensuring smooth discharge and stable operation.

Applications

Silo outlet lump breaking and discharge
Discharge pipe and chute anti-blocking systems
Pneumatic conveying line discharge points
Cement and building material powder systems
Power plant ash and mineral powder handling
Chemical powder and granular material systems
Fly ash, lime, and ground slag powder discharge
Bulk powder systems with caking or moisture sensitivity

Suitable Materials and Working Conditions Include

Cement
Fly ash
Mineral powder
Lime
Clay
Ground slag powder
Coal lumps and ore lumps
Caked gypsum and similar blocky bulk materials
Hot powders and calcined powder materials
Moisture-sensitive and easily caking powder materials
Pneumatic conveying systems under positive or negative pressure
Large-diameter silo bottom discharge applications

Technical Characteristics

Cylindrical housing with circular flanges for direct installation on round silos and pipelines
Low-speed high-torque crushing structure for impact, compression, and shear crushing
Internal screen ring for controlled discharge particle size
Uniform force distribution and compact overall structure
Good sealing performance with reduced dust leakage
Combined crushing, discharging, air locking, and anti-blocking functions
Smooth internal flow path with good material passage performance
Wear-resistant crushing claws and screen ring for long service life
Stable running performance with low vibration and low noise
Overload protection and anti-jamming capability for continuous discharge
Suitable for abrasive powders and harsh industrial operating conditions
Can be configured for high-temperature, explosive dust, and pneumatic conveying systems

Optional Configuration / Notes

Single-shaft, double-shaft, and heavy-duty structures can be selected according to material condition and required capacity.
Variable frequency speed control can be configured for process adjustment where required.
Anti-sticking coating can be used for hygroscopic and wet sticky materials.
High-temperature seals, stainless steel housing, and high-temperature bearings are available for hot powder applications.
Explosion-proof motor, explosion-proof grounding, isolation device, and enclosed rotor configuration are available for combustible dust systems.
High-precision sealing, air-lock rotor structure, and shaft-end mechanical seal can be configured for pneumatic conveying discharge service.
Model selection should be based on material type, lump size, nominal diameter, required throughput, discharge particle size, and site conditions.
