LM Vertical Coal Mills Demonstrate Their Strength in Coal Powder Preparation for Non-Ferrous Metal Smelting

As an important basic industry of the national economy, the non-ferrous metal industry is in a critical stage where scale expansion and green transformation proceed in parallel. With the in-depth implementation of environmental protection policies, the industry is facing the dual challenges of improving energy efficiency and reducing emissions. Against this backdrop, coal powder, as the core energy carrier in the non-ferrous metal smelting process, the optimization and upgrading of its preparation technology determine the quality of coal powder, combustion efficiency and energy utilization rate. Realizing the efficient and clean utilization of coal powder has become a core breakthrough to promote the low-carbon development of the non-ferrous metal industry.

Efficient Implementation of the Coal Powder Preparation Project

This project is an industrial furnace-matched coal powder preparation production line constructed by Liming Heavy Industry for a large domestic non-ferrous metal enterprise. Based on industry trends and its own development needs, the enterprise has planned and built this coal powder preparation project, aiming to reduce coal consumption, improve smelting efficiency in the smelting process, promote the realization of green and low-carbon production goals, and further enhance its competitiveness in the industry.

Processed material: Coal powder

Fineness: 200 mesh

Application: Coal powder preparation for industrial furnace matching

Equipment: Liming Heavy Industry LM vertical coal mill

In the early stage of project preparation, the enterprise conducted in-depth investigations on multiple grinding equipment suppliers for several months, covering various dimensions such as equipment performance and after-sales service. After strict screening, it selected Liming Heavy Industry's LM series vertical coal mills to build a modern clean coal powder preparation system integrating "safety and reliability, cleanliness and environmental protection, high efficiency and intelligence", which accurately responds to the energy conservation and emission reduction policies and regional economic development needs.

The person in charge of the enterprise's project said: "Liming Heavy Industry's technical solution not only meets our strict requirements on coal powder fineness and output, but also shows great advantages in energy consumption control and safety protection. In particular, its numerous successful cases in the field of coal powder preparation for non-ferrous metal smelting have filled us with confidence in the cooperation."

Coal Powder Preparation Process

Raw Material Pretreatment

Raw coal is screened from the raw coal yard, then sent to a conveyor or hoist, and finally transported to the raw coal silo for storage.

Vertical Mill Grinding

Powered by a hot blast stove, coal powder undergoes drying, grinding, and classification in the LM vertical mill, with precise control over fineness.

Safety Prevention and Control

Nitrogen protection + equipment explosion venting device + intelligent carbon dioxide fire extinguishing + CO-O₂ online monitoring system.

Finished Product Storage

Coal powder is collected by an explosion-proof air box pulse dust collector and then transported to the coal powder silo via pneumatic conveying equipment.
