1. Cement Silo Blocking – A Common Problem in Clinker & Powder Discharge
Twin shaft lump breaker for cement silo discharge plays a critical role in eliminating material arching, clinker blocking, and large agglomerates before downstream conveying.
In modern cement plants, material discharge from the silo bottom is a critical process stage. Cement clinker, cement powder, fly ash, and kiln dust often form lumps or agglomerates during storage due to moisture, compaction, or temperature variations. These lumps easily cause arching, bridging, and discharge blockage, leading to unstable material flow, reduced production efficiency, and even system shutdowns.
According to bulk material handling principles described by Wikipedia, arching and rat-holing are common flow problems in silos handling cohesive powders and granular solids.

2. What Is an Electric Twin-Shaft Lump Breaker Valve?
An electric twin-shaft lump breaker valve is a heavy-duty crusher valve installed directly beneath cement silos, hoppers, or discharge outlets. It integrates two counter-rotating shafts equipped with crushing blades that continuously break large clinker lumps and compacted material before they enter downstream conveyors or pneumatic conveying systems.
Unlike conventional lump breakers or rotary crushers, this type of breaker valve combines:
- Continuous crushing function
- Stable discharge control
- Compact valve-type installation
It is widely used as a cement silo bottom lump breaker, clinker crusher valve, or double shaft de-agglomerator in cement grinding and dispatch systems.
3. How Twin-Shaft Lump Breaker Valves Work
When material flows out of the cement silo, large clinker chunks or compacted powder fall into the crushing chamber. Two synchronized shafts rotate in opposite directions, pulling the lumps inward and crushing them into uniform particle sizes.
Key working features include:
- Self-feeding crushing mechanism
- Continuous discharge without material accumulation
- Stable rotation driven by an electric motor and gearbox
This design effectively eliminates material bridging and protects downstream equipment such as air slide conveyors, screw conveyors, and rotary airlock valves.
4. Key Advantages for Cement Silo Discharge Applications
Compared with single-shaft lump breakers or hammer crushers, electric twin-shaft lump breaker valves offer several critical advantages:
✔ High crushing efficiency for hard clinker and agglomerates
✔ Prevent arching and rat-holing at the silo bottom
✔ Protect pneumatic conveying lines and belt systems
✔ Reduce unplanned downtime and maintenance costs
✔ Compact structure suitable for direct silo mounting
✔ Stable and dust-controlled discharge operation
These advantages make them ideal for cement silo discharge, clinker feeding systems, and bulk powder conditioning.
In modern cement plants, the twin shaft lump breaker for cement silo is widely installed below silo outlets to eliminate clinker arching and ensure smooth material discharge.
5. Typical Applications in Cement & Bulk Material Plants
Electric twin-shaft lump breaker valves are widely installed in:
- Cement silo bottom discharge systems
- Clinker silo and raw meal silos
- Fly ash and kiln dust silos
- Air slide conveyor feeding points
- Screw conveyor and belt conveyor inlets
- Pneumatic conveying system feeding sections
They are especially effective in high-capacity cement plants where continuous, blockage-free discharge is essential.
This twin shaft lump breaker for cement silo is especially suitable for clinker silos, cement storage bins, and fly ash silos with serious blocking problems.
6. Twin-Shaft Lump Breaker Valve vs Traditional Lump Breakers
Traditional lump breakers are usually installed as standalone crushers and mainly focus on particle size reduction. However, twin-shaft lump breaker valves integrate both crushing and discharge control, offering:
| Feature | Twin-Shaft Lump Breaker Valve | Traditional Lump Breaker |
|---|---|---|
| Installation | Directly under silo | Separate crusher unit |
| Function | Crushing + flow control | Crushing only |
| Anti-blocking performance | Excellent | Medium |
| Dust sealing | Better | Limited |
This makes the twin-shaft design a preferred solution for modern cement silo discharge systems.
Compared with single-shaft crushers, a twin shaft lump breaker for cement silo provides higher breaking efficiency and more stable continuous operation.
7. Selection Tips for Cement Silo Lump Breaker Valves
When selecting a lump breaker valve for cement silos, consider:
- Material type (clinker, cement powder, fly ash)
- Maximum lump size and hardness
- Required capacity (t/h)
- Installation flange size and silo outlet dimensions
- Motor power and torque requirements
- Wear-resistant blade and housing materials
Proper selection ensures long service life and stable plant operation.
