double shafts disperser mixer

The double shaft mixer is used to spray, mix and transport the powdery materials by adding water through the relative rotation of two groups of shafts with spiral blades, to make the powdery materials reach controllable humidity. The equipment is mainly applicable to the humidification and mixing of raw materials in the fertilizer industry so that the materials can be fully stirred and have the function of conveying.

When the quantitative raw meal powder flows into the mixing tank from the blanking port, it is atomized and scattered to the raw meal powder through several water atomizers with relative pressure, and the ball core with consistent water content is formed after being stirred by the qualitative length shaft through the mixing blade. The whole mixing is divided into three areas: atomization area, mixing area, and unloading area. The mixing blade has good wear resistance and long service life.

double shafts disperser mixer Structural features

The double shaft mixer is mainly composed of casing, screw shaft assembly, driving device, piping, cover plate, chain cover, and other components (see the attached external supply drawing for details). The specific structural performance characteristics are as follows:

1. The shell is mainly composed of plates and section steel, welded in the manufacturer and assembled with other parts, which is the support of the double shaft mixer. The shell is tightly sealed, and there will be no flying ash and ash leakage.

1. The screw shaft assembly is the main component of the double shaft mixer. Its components mainly include a left-right screw shaft, bearing seat, bearing sleeve, bearing cover, gear, sprocket, oil cup, blade, and other parts.

The left-right spiral shaft requires high manufacturing precision and good process performance, and has strict matching requirements with the bearing seat, bearing sleeve, and bearing cover. The gear module is 8, the number of teeth is 60, and the tooth shape angle is 20 °; The sprocket pitch is 50.8, the number of teeth is 25, and the tooth shape is gb1224-85. Gears and sprockets are protected by protective covers, which can operate safely and effectively. The oil cap is a press-fit pressure injection oil cup, which is convenient and effective for filling lubricating oil. The blades of the double shaft mixer are made of composite ceramics which are wear-resistant and not easy to stick ash. The blade structure design is reasonable and simple, easy to replace after wear, and long service life.

1. The water humidification piping is mainly composed of connecting pipes, joints, and nozzles. The nozzle is a stainless steel atomizing cone nozzle, which is arranged above the mixer shell and arranged axially along the spiral axis to form a water curtain to facilitate the humidification and mixing of materials. The nozzle is simple in structure and easy to replace. It is made of stainless steel and is corrosion-resistant and durable. The moisture content of wet ash can be adjusted by operating the manual regulating valve on the water supply pipeline.

1. Cover plate mainly includes left cover plate, middle cover plate, right cover plate, hole cover, and manhole cover. Six manholes are set on both sides of the double shaft mixer to facilitate the normal overhaul and maintenance of the operator. A double shaft mixer is used for the pneumatic conveying end.

Structure and working principle

The double shafts disperser,double shafts mixer is composed of a driving part and a body part.

The driving part is composed of a motor, coupling, and reducer. Then, the roller chain drives the driving shaft on the body to rotate and drives the gear on the driven shaft and the driven shaft to rotate at the same time through the gear on the driving shaft.

After the materials enter the mixing tank from the feed port, the main and driven shafts equipped with spiral blades push the materials and mix them. After that, the materials are sent out from the discharge port and then loaded by the transport machinery.

Water is added to the materials at the same time as the mixing of the materials. The water is supplied by a water spray device composed of a water inlet pipe and a nozzle.
