Coalbriquette machine

1. 1.    Productintroduction:

Coalbriquette machine can also be called pulverized coal pressure ball machine, canbe used to suppress the coal, iron, briquette ball press molding process coldpressing, hot pressing molding, cold pressing; cold pressing and molding binderand binder less molding, binder mainly. According to the situation of ourcountry, the powder is formed by adding binder, middle and low pressure,non-drying and cold pressing.

Coalbriquette machine can be used to suppress the end of coal, iron, coal,aluminum, iron, iron oxide, carbon powder, charcoal powder, slag, gypsum,tailings, sludge, kaolin, activated carbon, coke and other various kinds ofpowder, powder materials, waste, waste, widely used in refractories, power plant,metallurgy, chemical industry, energy, transport, heating and other industries,the pressure ball machine production of molding material, environmentalprotection and energy saving, convenient transportation, improve theutilization of the waste material, and has good economic benefit and socialbenefit.

1. 2.    Workingprinciple:

Hostby electromagnetic adjustable speed motor provides the power to the belt wheel,a cylindrical gear reducer; the pin coupling is transmitted to the drive shaft.The driving shaft and the driven shaft are guaranteed to run synchronouslythrough an open gear. A hydraulic device is installed behind the passivebearing seat. The screw feeding device is driven by an electromagnetic speedregulating motor, and is driven by a belt wheel and a worm reducer to force thematerial to be pressed into the feed inlet. Due to the electromagneticadjustable speed motor constant torque characteristics, when the spiral feedingmachine material pressure feeding amount and the host material is equal to theamount required, can maintain constant feeding pressure stabilizing the qualityof pellet. If the feeding amount is too large, then the electrical overloadfeeding device; the feeding quantity is too small not into a ball. So skilledoperation is an important condition to ensure the normal operation of thepress.

Thehydraulic protection device is driven by the hydraulic pump, the high-pressureoil into the hydraulic cylinder, so that the axial displacement of the piston.The front of the piston rod is connected with the top of the head to meet therequirement of production pressure. When the between the two rollers feed orinto the metal block, the piston rod of the hydraulic cylinder pressureoverload, the hydraulic pump will stop, energy storage device to pressurechanges from buffer, overflow valve open return oil, piston rod displacementpressure and gap increase so that a hard object through a pressure roller,system pressure recovery normal can to protect the pressure roller is notdamaged.

1. 3.    Structuralcomposition:

Coalbriquette machine consists of three parts: a feeding part; two transmissionpart; three forming part.

1. 1.    Thefeeding part mainly realizes the quantitative feeding to ensure the material tobe evenly between the rollers.

2. 2.    Thetransmission part, the main drive system is: The electric motor- Triangularbelt- Reducer- Open gear-Roll.

3. 3.    Themolding part, mainly refers to the host part, the core part is the roller.

1. 4.    Installationand commissioning:

Briquetteball press machine must have a more balanced base pay attention to correctlevel, flat gap, with conveyor more and conveyor height, level corresponding,after installation, strict inspection each component is connected firmly,machine to check whether there is debris, add deceleration gear box and twolubricating oil to determine each component is correct before test machine.Test machine to see if it upside down, in the right direction to cargo turnedthirty minutes to see whether there is abnormal sound or heat in eachcomponent. It is found that the problem is solved in time, everything is normalto 300 kg dry (without the moisture of the coal powder, fine sand or refractorymaterials), dry grinding and polishing, and about five times, can be formallyput into production. Please note: water content on the ball into the pressureand mold release has a great impact, be sure to master, it is best to dry afterwet, no heavy car start.
