Product Q&A

Q:What materials can this machine crush?

It is designed for crushing various types of coke including machine coke, tamping coke, improved coke, petroleum coke, and other brittle materials like limestone.

Q:What is the output particle size?

The discharge size range is typically under 60mm, with over 80% of the output falling between 25mm and 80mm for uniform granularity.

Q:How does the cutting mechanism work?

It uses two tooth rollers rotating at differential speeds. The slower speed teeth lift the coke while the faster speed teeth shear it, utilizing an axe-shaped design.

Q:What are the available motor power options?

Motor power ranges from 15kW to 55kW depending on the model, with specific models like CQD-70 featuring a 22kW AC motor.

Q:What is the lead time for delivery?

Lead time varies by season: within 15 workdays during the off-season and approximately one month during the peak season.
