Coke powder usually piled like mountains and sold as ordinary fuel at a low price in many plants, has very high calorific value.This not only wastes energy, but also causes pollution.Coke powder recycling as a process to match the by-product coke powder with coal to make coke turns the harmful into the beneficial and waste into the valuable.

The process is surely a very good investment item with advantage of small investment, large gains in response to the trend of energy saving and environment protection. Earlier starts in investment, earlier wins in cost.

economic benefit of coke powder recycling

Coke powder, self- produced for self-ultilization, without purchasing investment and long-distance transportation, without further contraction during coking,that is to say, allocation of one ton coke powder can produce one ton of coke,it saves 1.3 ton of coal. Therefore, the economic value of coke powder recycling is much higher than that of thin coal, lean coal or anthracite.

Coke powder recycling can increase the coke powder value 300 -500 yuan per ton, can reduce the comprehensive cost of the finished products of coke 10-15 yuan per ton.

technical parameter of BETTER process

BETTER provides 6 kind of process according to capacity till the time when the operation mannual is published, the process will be probably increased or modified along with the development of productive practice.

Remarks
1. Power consumption refers to total power consumption of all the equipment in the system.
2. Investment refers to the total investment of equipment, civil engineering, installation, workshop and so on
3. All data is for reference, the actual condition and requirement of the customer shall prevail.
4. The above data is normal design data, the practical data of simple solution will be lower.

it solves a lot of problems of traditional process including: high wearing, large quantity of maintenance work, unstable capacity, huge volume taking big area of installation space, low efficiency, high power consumption, ponderous in weight increasing difficulty and complexity for repairing, poor environment protection performance due to impossibility to close the feeding and discharging hopper, strict requirement and high operation cost of dust removal equipment, etc.

Electrical control of BETTER process

weighing belt-conveyors of the mixing system must be interlocked with conveying belt conveyor. Other equipment may be controlled manually, semi-automatically or PLC central controlled
