Many coal mills are still buying a coal at high prices, and a spiral squeezer can crush cheap coal into a coal bar without lime, dry, steam, fuel costs can be cut off and small plants can afford。
How the hell did the coal stick work on the coal
The core of the coal bar is squeezed by a spiral. A spiral in the barrel, when the coal enters through the feed mouth, the blades push the powder step by step towards the feed mouth, the space becomes smaller and the powder is condensed. To the position of the coal rod model, the powder is forced over and over and out is round or six-foiled coal rods. The entire process, free of chemical glue, is based solely on physical pressure to create internal cohesion between coal particles, which takes less than two minutes。
The main components are organic, axle bearings, spirals, cartridges, feed outlets and coal rods. The seat is fully loaded, the axle is pinned to the spiral, the cartridge is a squeezed cavity, and the mould determines the shape of the product. Nitrogen fertilizer plants now use double spiral pressors, powder coal and around 16 per cent of water and adhesives in mixers, which are then modulated into the mixer, and come out with enough coal rods to burn directly into the gas furnace, without having to reprocess。
Which industries can't turn on coal rods
The core applications of coal rods are the gas systems of ammonia and gas plants. Used to make gas from coal or a ball of coal, coal is expensive, transport is problematic, and the particle size is unstable. With the conversion of coal rods, coal, beam, coal, lignite and smoke-free coal can be used. The raw materials are widely sourced and priced, gas stoves are more heat-efficient than coal, a ton of coal can heat 8 to 12 per cent, and stoves are pumped up。
In addition to gas generation, iron powder and aluminium powder formation are also suppressed by coal rods used for fuel in rural boilers and small kilns. In shandong, henan and anhui, a number of small-coated plants that could not burn a piece of coal in the past, they are crushing the surrounding pebbles and central coal into sticks, saving enough fuel to buy two more devices a year. In guangdong and jiangxi, pottery is also replacing part of the gas with coal rods, with a 30-40 per cent reduction in burning costs。
How much does it cost to dry without lime
Traditional coal ball formation is made of lime as a glue and involves a set of carbonized drying lines, with less than hundreds of thousands of items of equipment and tens of thousands of extra pieces of steam, power consumption and manual burning. Coal rods are squeezed in a purely physical manner, without lime, without a cauldron, without steam, with the equipment itself covering only a dozen square metres, saves investment and operating costs, and small plants are willing to change their accounts and return to the current cycle for a short period。
Fifteen tons of powdered coal per day, 200 to 300 dollars a ton of powdered coal and 500 to 700 dollars a ton of coal, saves 3,000 dollars a day for raw materials alone. The calculation of lime, dry energy consumption, steam, labour, 20,000 to 30,000 net profits per month. The equipment is $200,000, most of the year back, followed by net gains, and many of the coal mills have replaced the old equipment with the bill。
Helix and coal rods are key to life
The fastest wear is a spiral and a coal rod. Spiral axes are grinded daily by coal, the pore walls are squeezed by high pressure, and in a few months they become larger and less powerful. Spiral axes typically run for a year or two with a 45-point steel or chromium alloy steel, with a high-frequency fire above hrc58. Coal rods need to clear their tracks with coal feet every day to prevent coal powder piles from swelling to death and spend an extra 10 minutes saving a lot of money for the model。
Many plants ignore the lubrication of the bearings, and the bearings stop as soon as the entire spiral is burned, when the half-operate line is white, when the coal burned in the sky is wasted. Lithium resin is recommended for change every 500 hours in the axle bearings, with additional heat in the summer. There is an ash shield between the vent and the cartridge, the dust cannot reach the axle bearing, and the bearing can last more than six months。
How do you match the powdered coal and the glue
Before entering the machine, the powdered coal must be watered, usually with about 16 per cent of the water, and then 5 to 8 per cent of the excavated soil or clay powder must be added to the glue, so that the mixer can be sprawled into a band of arms and scattered into the ground. The water is too small to fall apart, and the water is too many spirals and the currents are so high that it jumps. The ratio has to be adjusted for each change of coal, so that the old formula is not used for new coal, or the eligibility rate falls directly below 60%。
Coal species vary widely. Smoke-free coal is hard, sticky, and the glue is added to 10 per cent; lignite itself contains high water, which can be reduced to less than 12 per cent. It is recommended that a small sample be taken and squeezed in the test module, with a hammer, and that the resistance of 8 to 12 kg/cm2 be qualified and then zoom into the official machine. Don't turn it on as soon as you get here. It's a lot cheaper than the official stuff。
Small factory picks coal rods for three parameters
Don't look at the spiral diameter and turn speed. Small aircraft with a diameter of 320 mm processed 10 tons per day and 500 mm medium power up to 30 tons. The rate of turn is normally 60 to 120 per minute, and the higher the rate, the greater the yield, the greater the twister the power of the machine. The choice is low, the choice is low, the choice is low, the choice is low, the choice is low, the choice is low, the choice is high, and it is the best cost-effective to match the actual output。
Second watch and transmission. The 15 kilowatts with the same specification is sufficient to be more than 7. 5 kilowatts of twirl, which is not easy to catch. The belt wheeling is cheap but the noise is short, and the gear case costs two or three thousand more but has a long maintenance cycle. The third is whether the manufacturer can model, round, hexagon, squares must be customised, not buy only one shape, but then buy another。
Are you cooking coal or coal? Do you want to get on a coal stick machine, or do you want to have a match or a device selection? Talk in the comment area, and i think it's a good idea。
