Every mineral processing project begins with two non-negotiable numbers: how many tons per hour you must produce, and how fine the final powder must be. No two plants are identical. A limestone operation feeding a dry mortar line may need 50 t/h at 0-3 mm, while a calcite processor supplying paint may require 8 t/h at 1250 mesh. That is why Shanghai Zenith Machinery Co., Ltd. builds grinding solutions around customized capacity and powder fineness, not around a single catalog number.

As a hi-tech engineering group, Zenith specializes in industrial powder grinding equipment. Our range covers 1-3 mm coarse powder, 20-400 mesh fine powder, 400-1250 mesh ultrafine powder, and 1250-3250 mesh micro powder. With ISO, CE, and CU-TR certification, and a network covering more than 180 countries and regions, we help customers match the right mill to the right duty.

Start with the Powder Fineness You Need

Fineness determines the grinding principle, classifier, and flowsheet. For coarse powder from 1 to 3 mm, the HM Hammer Mill accepts feed up to 50 mm, delivers 0-3 mm output, and reaches 3-50 t/h. It is popular in dry mortar, animal feed, agriculture, and construction materials.

For fine powder between 20 and 400 mesh, Zenith offers several proven mills. The MTW European Trapezium Mill produces 80-400 mesh at 3-22 t/h with feed up to 35 mm. It serves agriculture, chemicals, paint, wall putty, steel plants, and water treatment. The MTM European Trapezium Mill is a stable, 30-year-proven design for 80-400 mesh with low investment. The Raymond Mill covers 10-325 mesh at 3-22 t/h with intelligent control and 99% screening efficiency. For larger fine-powder plants, the LM Vertical Grinding Mill handles 3-340 t/h, input up to 70 mm, and output from 80 to 400 mesh.

For ultrafine and micro powder, the LUM Ultrafine Vertical Grinding Mill and XZM Ultrafine Grinding Mill are key options. LUM integrates grinding, separation, and transportation, producing 325-2500 mesh at 5-18 t/h from feed up to 10 mm. It suits calcite, marble, limestone, talc, dolomite, barite, kaolin, wollastonite, gypsum, feldspar, and pyrophyllite. XZM reaches 325-3250 mesh with single classification and capacities from 0.5 to 25 t/h. It can achieve D97 < 5 micron in one pass for paint, PVC, plastic, paper, and chemical industries.

Match Capacity Without Overbuilding

Capacity customization is a balance of feed size, hardness, moisture, target fineness, uptime, and future expansion. Zenith mills span a wide window. XZM starts at 0.5 t/h for specialty micro powders. MTW, MTM, and Raymond serve 3-22 t/h fine-powder lines. LUM covers 5-18 t/h ultrafine production. For high-volume operations, LM reaches 340 t/h, LM-Y reaches 330 t/h, Ball Mill reaches 250 t/h, and Mining Ball Mill reaches 300 t/h.

This range lets a project be designed around actual production targets instead of forcing the process to fit a standard machine. A 10 t/h wall putty line, a 40 t/h GGBS grinding station, and a 200 t/h cement raw meal circuit require different equipment, layouts, and automation. Zenith engineers evaluate the complete circuit, from crushing and feeding to grinding, classification, dust collection, and finished powder transport.

Choose the Mill by Application

Application experience matters. MTW and MTM are strong for fine mineral powder with moderate capacity and limited plant area. LM is built for 24-hour continuous operation, stable quality, and easy monitoring, making it popular in large mineral powder, cement, GGBS, and coal grinding plants. LUM focuses on high purity and energy savings, reducing energy consumption by 30%-50% compared with ordinary mills. XZM offers high efficiency and low energy consumption, reported as 40% higher efficiency and 70% lower energy than air-flow and stirring mills when producing the same powder.

For pre-grinding and sand making, LM-Y combines both functions. It processes up to 330 t/h with input ≤20 mm and output <5 mm, and its hydraulic system simplifies maintenance. Ball Mills and Mining Ball Mills remain relevant for metallurgy, chemical, cement, refractory, fertilizer, glass, ceramics, and mineral processing, offering dry or wet grinding and strong material adaptability.

Customization Includes Automation and Environmental Control

Modern grinding plants must be clean, safe, and easy to operate. MTW and MTM use modular impeller adjustment to change fineness. XZM uses a variable frequency classifier for precise control. LM, LUM, and LM-Y feature hydraulic adjustment and automatic control. Sealed operation under negative pressure, pulse dust collectors, low vibration, and low noise help meet environmental standards. High-quality steel and wear-resistant parts reduce downtime and protect powder purity.

To specify a customized mill, prepare key data: material type, feed size, moisture, target mesh or micron, required tons per hour, working hours, available power, plant layout, and automation needs. With this information, Zenith can recommend the most economical configuration and provide a complete system from bulk material to finished powder.

Frequently Asked Questions

Can one mill produce both coarse and ultrafine powder?

Usually no. Hammer mills handle 0-3 mm, MTW and MTM handle fine powder, LUM handles ultrafine powder, and XZM handles micro powder up to 3250 mesh.

What capacity range can Zenith customize?

Depending on the mill and process, capacity can range from 0.5 t/h for XZM ultrafine grinding to 340 t/h for LM vertical grinding. Complete lines are engineered around the required output.

How do I choose between MTW and LM Vertical Mill?

MTW is ideal for 80-400 mesh fine powder with moderate capacity, smaller area, and lower investment. LM is better for large capacity, continuous operation, and high automation in cement, GGBS, and coal grinding.

What is the finest powder Zenith equipment can produce?

XZM can produce 325-3250 mesh powder and reach D97 < 5 micron in one pass. LUM can produce 325-2500 mesh with high purity and energy efficiency.

Does Zenith support overseas installation and service?

Yes. Zenith covers more than 180 countries and regions with overseas offices in more than 30 countries. Support includes configuration, commissioning, training, and spare parts.
