Compressed or Chinese coal production line includes 8 machines, which are: - Mill - Conditioner (sieve vibrator) - Blowing torch + heat boiler - Sinus tubes - Turbine suction - Centrifugal cyclone - Extruder (with 30 hp engine) + Mardon and anti-wear cylinder - Furnace (industrial or traditional) The production capacity of the extruder (the main device of the production line) is 200 kg per hour, and we use Mardon and anti-wear cylinders, which have a long life, which has greatly relieved the producers. Sawdust is the main raw material of this production line, which is used by about 70%, and coal (charcoal) (charcoal) and walnut bark together by 30%. We provide the production line with industrial and traditional furnaces. Industrial furnaces designed and manufactured by this art industry from the beginning are a useful device that has a filter and no smoke that does not pollute the air and the environment. . Industrial furnace specifications: 2 ton input capacity - 40% conversion ratio - has automatic temperature control system - indirect heat - no smoke - 20 hours working process - single step - gas or diesel fuel - single phase electricity Traditional furnace specifications: 400 kg input capacity - 30% conversion ratio - no heat controller - direct heat - has smoke - 24 hour working process - two stages - no fuel - no electricity Industrial furnaces also have the ability to convert wood to coal. The production line needs 3-phase electricity of at least 50 amps and gas or diesel.
