Corncob Grinding Mill Case Study: 40-Mesh Powder at a Combined 1200 kg/h from Two Mills in Hebei

Feedstock and Processing Application

A corncob grinding mill processes the cob that remains after the corn kernels have been removed. This project in Hebei, China uses 5 mm corncob particles as the feedstock to produce corncob powder.

Equipment Used in This Project

The project uses two Tianyuan TYLM1200 grinding mills. This page documents this model’s application to corncob processing. For the model description and technical specifications, see the TYLM1200 Vertical Wood Powder Mill listed under related equipment on this page.

Finished Product and Actual Output

The finished product has a fineness of 40 mesh, with a combined site output of 1200 kg/h from the two mills. Fineness and output together describe the processing result; both should be considered when defining a new project’s requirements.

Information to Prepare for Equipment Selection

• Feedstock photos or samples: identify whether the feed consists of whole corncobs, pre-crushed material or another form, and provide size information.
• Material condition: provide moisture information and indicate whether other materials are mixed into the feed.
• Product requirements: specify the target fineness, screening or testing standard and intended use of the powder.
• Output and site conditions: state the required hourly output, available space and existing equipment to help define the configuration.

These details support equipment selection and assessment of any pretreatment needs. The material name alone is not enough to establish that every corncob project can use the same configuration.

Frequently Asked Questions

Does this project process corn kernels?

No. It processes 5 mm corncob particles. Corncobs are the cores left after the kernels have been removed. The finished material is corncob powder; this case does not provide performance data for corn-kernel milling.

Does 40 mesh mean every particle is the same size?

40 mesh is the finished-product fineness reported for this project. It does not mean every particle has an identical size. To compare it with another project's requirements, confirm the sieve standard, test method and required passing percentage. Those test details have not been supplied for this case.

Can another corncob grinding project achieve 1200 kg/h?

1200 kg/h is the combined site output of the two mills in this Hebei project. The achievable output for a new project needs to be assessed against its feedstock condition, target fineness and equipment configuration rather than assumed from this case.

Discuss Your Corncob Grinding Requirements

To assess equipment for your project, share feedstock photos, target fineness and required output, together with the intended use of the powder. These details will help Tianyuan confirm equipment selection and configuration.
