The crushing process of coal gangue in mining

That particle dimension regarding slack coal is really 0 ~25 mm. That use concerning coal is really substantial within power energy amenities. Create a 1 trillion kW power power plant by way of instance, coal use sums to 14, 000- 13000t each day. It’ll consider 60% ~ 80% in the complete expense with regard to bringing in electrical energy. So it’s very essential program that coals to much better correct size. It’s advisable to adopt right coal mill with regard to coal milling plant. This can not alone improve the use concerning coal, but additionally help with power protecting, environmental safety, fiscal benefits. Reported through the market investigation, up and down roller mill must be used almost all significantly.

Electric Industry observers Reporter Wang Bing Ning from Beijing 2 12, reporter learned from the power system, there are already Huaneng Group, Datang Group, Huadian Group and SVA Group 4 with Russia and Indonesia and other overseas coal companies signed a 20 million tons, 260,000 tons, 13 tons and 20 million tons of coal purchase agreement, at the same time, the power system is also combined with Australia’s overall share of coal a coal enterprise bargaining agreement, plans to increase purchases will be about 70 Australian coal CIF U.S. dollars / ton (5800 kcal steam coal).

There will also be additional milling generators for instance regular Raymond mill, Roller mill, Trapezium mill, for instance. They might also fulfill a number of conditions regarding milling coal directly into several sizing’s in addition to sorts. Buyers could make the ideal coal noted by its distinctive requirements.

Suggestions of coal gangue crushing process:

1. If the particle size is about more than 40mm, we often choose jaw crusher for coarse crushing together with hammer crusher or other crushing equipment for tertairy crushing. And the crushing process is commonly used in production line. For example, the crushing line in Beijing, Shandong, Jilin, Liaoning and Heilongjiang and so forth. If particle size is less than 40mm, coal gangue can directly be sent into tertariy crusher for second stage crushing, turning two-stage crushing or three stage crushing into one-stage or two-stage crushing.

Thus not only save power,but also simplifies the production processing. For example, Tonghua, Jilin Bureau of Mines Iron Works of gangue material, most of the particle size below 30 mm; If gangue with partical size below 2mm accounts for more than 20%, it is recommended the raw materials should first get through vibrating screen, after which materials above screen go for coarse crushing and fine crushing, and materials under screen directly go into the mixer before the aging library.

As a professional and the best mining machinery manufacturer in China, Hongxing Machinery is always ready to provide the superior teeth roll crusher, aggregate mixer, and these machines have the most competitive price and the most reliable quality so that they are the top choices for the high performance crushing equipment.
