Pulverized Coal Preparation Production Line

Pulverized Coal Preparation Production Line

Capacity:1t/h-40t/h
 
Main Equipment:Coal Ball Mill, Powder Separator
 
Application Materials:Anthracite, Meagre Coal, Soft Coal, Brown Coal, Shale
 

Overview

Application Materials: Anthracite, Meagre Coal, Soft Coal, Brown Coal, Shale
Our Pulverized Coal Preparation Production Line is composed of Raw Coal Storage & Transportation System, Grinding System, Dust Collecting System, Electrical & Instrument Automation System. By the consideration of safety protection for equipment and system, explosion venting valve and nitrogen protection port are adopted at hot air inlet pipeline of Air Swept Coal Mill and coal air output pipeline. Speed of Powder Separator is regulated by VVF, the output fineness could be controlled by adjustment of frequency converter by remote control.

Features

1. Saving Energy
Air swept coal mill is an ideal coal processing equipment that can both grind and dry, with characteristics of high efficiency, energy saving, environmental protection, 8% and above of its grinding coal can pass through the 200 mesh screen, and the water content can be under 2%, it is an ideal grinding equipment for coal powders that are used in industrial furnaces and rotary kilns and other equipment.
2. Uniform particle size
The improved O-Sepa classifier is a kind of high-efficiency classifier developed on basis of the technology of common O-Sepa classifier and using the most advanced technology in the world. The distribution of finished particles is more uniform, while the particle size ratio is more reasonable.
3. Environmental protection
Effective measures have been taken to guarantee strict environment protection standards. Different efficient dust collectors are set at all dust producing points according to different characteristics of waste gas.
4. High degree of automation   
There is no manual operation in the process of mill running, which realizes the automatic control with long-term, stable, effective, makes milling process more stable, realizes fine work of production.
