Cement Screw Conveyors and Spare Parts

What does a cement screw conveyor do?

The screw conveyor carries cement and fly ash from the silo to the weigh hopper. When it does not run properly, cement weighing takes longer, the cycle time grows and the plant's hourly output drops. We supply spare parts, and complete screw conveyors when needed, for batching plants of different brands.

• Flight and shaft: the screw that moves the cement; worn flights reduce conveying capacity.
• Hanger bearings: support long screws in the middle and are the parts most exposed to cement dust.
• End bearings and seals: bearings and dust seals at the inlet and outlet.
• Gearmotor: the drive unit.
• Connections: butterfly valve connection at the silo outlet, flexible bellows and flanges.

Signs of trouble

Slow cement weighing, noise, vibration or heat from the screw, dust leaking at the ends, or the motor tripping on overload. Send the tube diameter and length, motor and gearbox label photos and photos of the worn part through our WhatsApp line or contact form.
