Coal Crushing Process Overview

coal oreCoal has played an important role in modern industry. The coal is processed and crushed to increase the efficiency and protect environment. In order to use coal more rationally, efficiently and effectively, the coal need to be processed and crushed into different sizes, 0 ~ 25 mm particle size for coal gas stove , 25 ~ 8 mm for steam locomotive, 25 ~ 6 mm for the industrial furnace, and coal power plant requires grain coal of 0 ~ 25mm.
The general hardness of coal is 1-4. After coarse crushing by jaw crusher, fine crushing by impact crusher, and sieved by vibrating screen, coal can be processed and crushed into different sizes of the requirements. SBM jaw crusher, impact crusher for coal crushing have been widely used in the coal industry and mining industry, for its high and unique quality. They can crush coal at large quantity and high efficiency. In addition, SBM vertical shaft impact crusher can crush coal into much smaller sizes to meet specific requirements.

Coal Mill for Producing Slack Coal

coal mine plantThe particle size of slack coal is 0 ~25 mm. The slack coal is often used as combustion agent in steel company, thermal power plant, etc. The consumption of coal is quite large in thermal power plants. Take a 1 million kW thermal power plant for example, coal consumption amounts to 11,000- 13000t a day, which takes 60% ~ 80% of the cost for generating electricity. It is advisable to adopt appropriate coal mill for coal grinding. This can not only improve the utilization of coal, but also contribute to energy saving, environmental protection, economic benefits.

According to the market research, vertical coal mill is used most widely. There are also other grinding mills like traditional raymond mill, roller mill, trapezium mill, etc. can also meet different requirements for grinding coal into different sizes and types. Customers can choose an appropriate coal according to their specific needs.

Coal Mining Equipment

The Mohs hardness of coal is usually under 5, So can use jaw crusher, cone crusher, mobile crusher or hammer crusher etc. to handle it. After the coal has been crushed, we can use a vibrating screen to grade the coal by size and then transport the coal via belt conveyors. In this process, dewatering screen is an optional equipment to remove water from the product.

In fact, we rarely use only one crusher in coal crushing process. Usually we compose these coal crushers into a complete coal crusher plant. A complete coal crusher plant includes crushing and screening machines. Jaw crusher is the primary crusher, impact crusher is the secondary crusher, cone crusher is the fine crusher. Raw coal is transported between these coal crushers through belt conveyor. The finished crushing coal materials is screened out by vibrating screen. The eligible coal materials enter into further process, while unqualified pieces return to the coal crusher for crushing again. In this coal crushing process, coal can be crushed into 30-50 mm. If you need coal powder, coal particle is grinded into powder by coal mill.

Coal Grinding Mill

coal mining roller millcoal mill is also called coal pulverizer,It is a popular name for grinding mill.Coal mill is an efficient tool for grinding coals into micro powders in coal mining industry.

Vertical coal mill also called coal grinder is the most used machine for coal grinding according to our mining experience.Raymond mill is also the early coal mill, the capacity of this coal mill can be up to 6-8 t/p.Ball grinding mill is the early coal mill used in coal powder plant, there are two types, wet ball mill and dry ball mill.

Raw coal is fed through a central coal inlet at the top of the pulverizer and falls by gravity to the rotating grinding table, mixing with classifier rejects returned for re-grinding.Centrifugal action forces the coal outward to the grinding ring where it is pulverized between the ring and three grinding rollers.

Coal mill include ball mill,raymond mill,vertical mill,MXB Gridning Mill.In coal crushing process, several types of coal crusher are used,such as jaw crusher,impact crusher,cone crusher and mobile crusher.Usually a complete coal milling line includes coal mill, impulse dust cleaner, piping device, cyclone collector device, classifier.

Coal Washer

coal mining washerCoal washer is an important washing machine in coal washing process. We know, when the raw coals are mined from underground, they need to pass some coal working procedure so that coal can be used in our modern life.

Coal washing is an essential pre-process of coal cooking. Coal can divide into raw coal and clean coal. Raw coal is generally used as fuel for energy, clean coal or fine coal is used for coal cooking.

Clean coal should be washed with water to sulfur, to impurities and other industrial processes, in order to achieve the criteria used coke. So, coal washer also called coal washing machine plays an important role in this coal processing.

Coal Conveyor

coal mining belt conveyorCoal conveyor means a belt conveyor used for conveying raw coal or coal ore stones. It’s applied widely in coal mining industry. When we transport raw coal to the ground or transporting coal on the ground, coal conveyor can do savings in manpower and improve efficiency greatly.

SBM is a famous conveyor company and conveyor belt manufacturer in the world. SBM coal conveyors consist of standard parts and they have the advantages of large transfer quantity, simple structure, easy maintenance and standard parts. They are widely used in mining, metallurgy and coal industry to transfer sandy or lump materials, or packaged materials.

Coal conveyor system is consisting of a metal frame with rollers at either end of a flat metal bed. The belt is looped around each of the rollers and when one of the rollers is powered (by an electrical motor) the belting slides across the solid metal frame bed, moving the product. In heavy use applications the beds which the belting is pulled over are replaced with rollers. The rollers allow weight to be conveyed as they reduce the amount of friction generated from the heavier loading on the belting.

Coal conveyors can now be manufactured with curved sections which use tapered rollers and curved belting to convey products around a corner.

We also offer spare parts and original wear parts related to the coal conveyor.
