Material: Calcined petroleum coke

Input Size: <200mm

Output Size: 200mesh, D70

Capacity: 7TPH (Per set)

Equipment: Two sets of MTW175 European Trapezium Grinding Mill

Project Profile

A listed company in Sinkiang, China is engaged in R&D, production and sales of silica-based materials. Its main products include organic silicone monomers, rings and downstream products. This company has a good fame in the industry. It has ever, as one of members, drawn up and formulated the Safe Production Specifications of Industrial Silicon.

This project was about carbon anode whose material was calcined petroleum coke. Because of industrial specialties, the requirements on carbon anode were strict. During operation, flawed products must be crushed, ground and then recycled. So, grinding mills were necessary.

After professional technicians from the company compared and analyzed grinding mills on current markets, the company finally attached preference to SBM’s European Trapezium Grinding Mill and bought two sets of MTW175 Grinding Mills. The project has been put into operation in January, 2018. At present, both grinding mills are stable. The output meets expected requirements.

Project Advantages

The host uses the bevel gear to achieve whole transmission, stable and reliable. There is no need for a speed reducer. So the installation and adjustments are easier and the failure rate is lower.

Professional customized fans are used to satisfy the height requirement of powder conveyance. They effectively increase the output of grinding mills and reduce noises.

All 3 systems (the host, the fan and the powder concentrator) uses dilute-oil lubrication. Excellent lubricating conditions extend the service life of facilities and guarantee a long-term safe operation.

The wear-resistant air intake volute is unaffected by resistance. So, not only can the pneumatic conveying efficiency in the mill be increased, but also maintenance costs can be cut a lot.

The seal of grinding rollers adopts innovative and practical labyrinth seal and other multiple sealing designs to ensure using performance of grinding rollers.


At present, SBM has accumulated too many projects in petroleum coke industry. Most of projects are distributed among Shandong, Shanxi, Sinkiang and some other places. Numerous practices reveal that performances of SBM’s grinding mills are trustable and reliable.
