Screw Feed Roller Press for Charcoal Dust Briquetting(86-15978436639)

(1) Screw feed roller press for charcoal dust briquetting machine is used in powder material that require lower moisture or free moisture, like lime stone, metal magnesium powder, aluminum oxide, aluminum dust, etc. various kinds of dry powder briquette making.

(2) Material definitely forbid to contain iron or other hardness bulk stuff, it will damage roller and roller shaft once fall into machine. If impurity is too much, better to attach iron-remove device and screener.

(3) If material to be pressed need to add binder, our company can offer appropriate binder type for reference, or customer make it by self.

(1) This series briquetting machine mainly process coal powder, various mineral powder, etc. with a certain loose density. And molding roller diameter is bigger, squeezing area is bigger, so pressure is bigger.

(2) Ensure material feed into roller evenly, material dosing step is very important, normally, has two ways, 1.belt feeder to feed material, it is more popular among customer for economic and practical. 2. Screw compression feeding. Material dosing purpose is to ensure machine host running steady, loading steady, when feeding volume beyond discharge volume will cause machine overloading, even cause machine stop running.

(3) When feeding volume lower than machine output volume, then briquetting effect will be not good, briquette intensity is not strong, thus, master feeding operation is a important step in machine running, that is experienced operational skill is an important factor to ensure roller press machine work norm

(4) Screw compression feeding main advantage is by adjusting screw rotating speed to gain required pre-pressure, and make powder material get larger compression ratio, and prepare for roller high pressure molding.

(1) This series roller press machine is main motor through V-belt drive reducer, and then through coupling send force to active shaft.

(2) Active shaft installed active gear, and passive shaft install passive gear.

(3) When active shaft running, active gear will drive passive gear rotating so as to move passive shaft, finally make two rollers running synchronized (same speed opposite rotate), passive roller is held out against hydraulic cylinder piston, hydraulic system cause circuit, hydraulic system control valve guarantee system pressure.

(4) Material feed into roller press machine hopper evenly by dosing device, and is controlled by hopper adjusting baffle, make material into two rollers evenly. Same speed opposite rotate roller unit molding pressure for material from smaller to bigger, when reach to roller center ssure is maximum. When material pass this ding pressure become smaller quickly, briquette fall off successfully.

When feeding volume lower than machine output volume, then briquetting effect will be not good, briquette intensity is not strong, thus, master feeding operation is a important step in machine running, that is experienced operational skill is an important factor to ensure briquette press machine work normal.

Screw compression feeding main advantage is by adjusting screw rotating speed to gain required pre-pressure, and make powder material get larger compression ratio, and prepare for roller high pressure molding.
