Break up feeding machine and utilize spiral pulpous state blade above twin shaft, the high humidity entered in a cabinet high bonding group material is carried out rotary-cut and breaks up, material is processed into powdery or bulk, is convenient to material and enters rotary drying machine smoothly.
Rotary drying machine is the dryer of a large amount of material of a kind of drying and processing, and owing to operating reliably, turndown ratio is large, strong adaptability, treatment capacity are large, so be widely used in the industries such as cement, mine, building materials, chemical industry, grain, composite heat transfer.Wet stock adds from the higher one end of dryer, and hot blast is entered by low side, becomes counter current contact with material.Along with the rotation of drier body, run to the one end end of compared with.Cylinder inboard wall is equipped with flight, and its effect material is taken up and spreads down, and the surface in contact of material and hot blast is increased, to improve drying rate and to promote that material advances.Wet stock is in cylindrical shell in movement forward, and abundant and hot blast carries out heat exchange, makes wet stock be able to drying, then sends through conveyor at discharge end.
Tornado dust collector can by dryer expellant gas be with material to trap.The principle of fly-ash separator is that dust-contained airflow is rotated, and to be separated by grit and to trap in wall, relend and help action of gravity to make grit fall into ash bucket by means of centrifugal force from air-flow.
The effect of induced draft fan is that the low temperature of discharging in dryer contains humid gas, and makes to maintain certain negative pressure in dryer.
Coal-grinding and powder-spraying machine is the combine of sledge mill pulverizing and centrifugal air blast, the raw coal being less than 20 millimeters can be worn into fine powder and burn for coal burner.
Coal burner is that one can allow coal dust Thorough combustion at short notice, produces the equipment of high-temperature hot-air.To add the coal dust in combustion chamber and mix with excess air, spray into complete suspension combustion in combustion chamber, thermo-efficiency be high, Increasing Production and Energy Saving, and the hot blast of generation directly enters dryer, discharges without waste gas.
Two storehouse batching functions join two kinds of materials, effectively can ensure the accuracy of proportioning, greatly can alleviate the labour intensity of material loading part.It is simple that the machine has adjustment, the features such as easy to operate batching is accurate, and the rotating speed of blending process mainly by adjusting frequency control motor realizes fixed than dosing, is a kind of desirable continous batching device.
Vertical crusher is used for the effect of impact block or granule materials being passed through high speed centrifugation tup, makes material become below 3mm powder and uses, also have mixed uniformly effect simultaneously to two or more different raw material.
Dry powder feeding machine is mainly used in the interpolation of dry powder caking agent, and the rotating speed of dosing process mainly by adjusting frequency control motor realizes fixed than dosing, and output can adjust as required, and setting range is large.
Biaxial rneader is mainly used in being uniformly mixed of various powder and granule shape material.Have mixing effect good, productivity is high, and energy-saving effect is remarkable, the features such as conformability is strong.
Ball press to prepare compression moulding under effect that the material that is stirred extrude two pressure roller reverse rotations by the machine, and the ball-type on pressure roller can require making according to user.
The effect being connected each equipment, between 16-23 °, is played in the rotary conveyor elevation angle, is mainly used in the conveying of each equipment room material.
