"GEC environmental protection coin" is suspected of pyramid selling, which is deceptive
"GEC environmental protection coin" trading mode has been widely spread, which takes "ecological environment protection", "zero investment", "zero risk" and "high income" as labels, and draws people into the partnership to pull down the development capital chain. Instry experts pointed out that the environmental protection coin can basically be classified as a circle. The appearance of disk circle is virtual currency, and the core is capital disk. The former's income comes from the later's capital. This model is not only suspected of ICO in disguise, but also suspected of MLM
extended information:
"GEC environmental protection coin" is obviously in line with the nature of pyramid scheme
one is to solicit customers with extremely high returns and declare that they only go up but not down, which has great attraction to investors
the second is to build the head MLM framework, build the membership mode, and realize the viral sales of GEC
Third, its sales and operation dare not be exposed to the "sunshine", but only through private means such as wechat group, which has the attributes of high concealment and avoiding supervision. Above all, the income model of "GEC environmental protection coin" has seriously deviated from the nature of bitcoin like assets, and even violated relevant laws and regulations. It is suggested that investors should guard against similar virtual currency investment model. He Nanye further stressed that this kind of mode can be identified as ICO, the core is illegal ICO, and the means is MLM modeThe equipment needed for the ore powder proction line includes the main equipment, vertical mill, and the rest are auxiliary equipment: motor, st collector, finished proct bin, conveyor belt, belt conveyor, elevator, feeder, etc
working principle of main equipment:
slag enters into the mill through the screw feeder, and the material falls to the center of the grinding plate under the action of gravity. The grinding plate is connected with the recer and rotates at a constant speed. Through the rotation of the grinding plate, the material is evenly distributed on the lining plate of the grinding plate. Under the pressure of the hydraulic system, the grinding plate is connected with the recer, The grinding roller nips the slag material and grinds it
under the action of centrifugal force, the crushed slag is thrown to the edge of the grinding plate, and most of it is blown back to the grinding plate to continue grinding under the action of high-speed air in the wind ring, and part of the powdery material rises to the separator through the middle shell of the mill with the high-speed air. In this process, the material and hot gas are fully heat exchanged, and the water is evaporated rapidly, so that the remaining water is less than 1%. The materials that have not been ground to the specified requirements are selected by the separator and sent back to the grinding plate for regrinding. The materials passing through the separator enter the st collector with the air flow
process flow of slag proction line:
the stacked slag is picked up and fed by forklift and transported by belt conveyor. In the process of transportation, slag raw materials are removed and screened by iron remover and vibrating screen, and then enter the vertical mill for grinding through weighing equipment bin and hoist. With the help of the hot air provided by the hot blast stove, the ground slag is selected by the powder concentrator and dried at the same time. The slag powder meeting the fineness requirements is finally transported to the st collector for collection and storage, and then enters the finished proct warehouse for storage by air conveying chute and elevator
profile of vertical mill:
(1) the drying process of the ore powder dryer is advanced, adopting high-temperature rapid drying process, with large heat transfer coefficient, high thermal efficiency and high drying intensity
(2) the combination of high-speed stirring drying and air flow drying can fully disperse viscous materials, greatly improve the contact area between materials and thermal medium, which is concive to the drying process
(3) special scraping device is used in the ore powder dryer to avoid the phenomenon of material sticking to the wall
(4) wide application range, simple operation, small maintenance and stable proct quality
(5) the mineral powder dryer is specially designed for drying mineral powder, with variable rotating blade angle and adjustable rotating shaft speed
(6) the upper part of the ore powder dryer body is equipped with a wet material reflux layer, and the airflow dryer is equipped with a special mixer
three equipment composition and working principle
1) the complete set of equipment of mineral powder dryer is mainly composed of drum crushing dryer, combustion furnace, feeding screw, discharging screw, conveying pipeline, st collector, air shut-off device, inced draft fan, control cabinet, etc
2) working principle: the ore powder is directly sent into the drum crushing dryer by the feeding screw, which is repeatedly picked up and scattered by the plate on the inner wall of the drum. After being dispersed by the crushing device, the material fully contacts with the high temperature medium with negative pressure to complete the heat and mass transfer process. Due to the inclination angle of the drum and the effect of the air diversion, the material moves slowly from the feed end, and is discharged by the discharge screw after drying. The tail gas is discharged into the atmosphere after being removed by the st collector

The dry powder mixer is also called dry powder mixer. When mixing, the materials in the mixer are affected by two rotors in opposite directions. The blade with animal material rotates counterclockwise along the inner wall of the slot. On the one hand, it turns left and right with animal material. In this area, no matter the shape, size, and density of the material, the two rotors overlap, It can make the material float up in the instant weightlessness state, which makes the material form a full range of continuous circulation in the trough, and shear each other, so as to achieve the effect of rapid, soft and even mixing.
the dry powder mixer is a vertical mixer, which can work alone, and it can work together with the conveyor, storage tank, electronic metering automatic packaging machine (applicable to the valve pocket, saving 3-4 workers, It is a new proct of traditional proction technology.
the dry powder mixer is made up of a variety of dry powder and fine granular materials (such as putty powder, plaster, dry powder mortar, color cement, various mineral powder, chemical materials, etc.) Dry powder mixer is a new type of high-efficiency mixing equipment, which is widely used in putty paste, stone paint, dry powder, putty, medicine, food, chemicals, feed, ceramics, refractories, etc., i.e. the mixing of powder, i.e. powder and mortar, chemical instry, compound fertilizer, dye, pigment, rubber, building materials, refractories, rare earth, plastic glass and new materials Solid solid (i.e. powder and powder) and solid slurry (i.e. powder and slurry) mixing in nuclear energy materials and other instries

II. Brief introction of concrete:
concrete, referred to as "concrete (T) ó NG) ": refers to the aggregate cemented by cementitious materials into a whole engineering composite. Generally speaking, the term concrete refers to the use of cement as cementing material and sand and stone as aggregate; Cement concrete mixed with water (including admixtures and admixtures) in a certain proportion, also known as ordinary concrete, is widely used in civil engineering.
