M-226 / M-440 Blenders Operating Principle

The vertical blender basically consists of a casing and a centrifugal pump impeller which are mounted vertically. The suction side has a double-wall pipe that keeps the inlet of solids separate from that of liquids, thus avoiding the formation of lumps before the material enters the casing.

The liquid enters the mixing chamber at a high speed, thereby creating a vacuum at the center of the impeller, which causes the suction of the solids. The introduction of solids can be regulated by means of a valve situated at the bottom of the hopper.

Design and Features

• Simple and versatile assembly for quick and homogeneous mixing of a great variety of solids without contact with the air.
• Complete mixing with recirculation of the product
• In some applications, it can be used in line, without recirculation.

Hopper vibrator

Considering the problems with the complete discharge of solids such as very fine powders, we offer the option of installing a vibrator in the hopper.

Pneumatic vibrator: The vibration is produced by means of a roller rolling on steel grooves. The frequency of vibration is changed by regulating the entry of air into the vibrator. The vibration keeps the flow of solids until the hopper is completely empty, thus no solids are left on the walls of the hopper.

If strong vibration is required, the mixer will be adapted to operate under the relevant conditions. This adaptation is made by means of an anti-vibration support for the hopper and an elastic coupling

Solids detection sensor

Due to the high degree of automation of the processes, it is important that all the parameters are controlled. We offer the option of adding one or two solids detection sensors to the hopper.

These sensors provide a signal to indicate lower and/or upper solids level in the hopper.

The signal of the lower level sensor can be used to control the valve in the lower part of the hopper in order to avoid the entry of air into the mixing chamber. The upper level sensor can be used to control the solids feeding unit.

This type of sensor uses a high frequency signal in the tip area to detect solids. The detection sensibility can be adjusted and it can be used for all types of products, solids, granules, liquids, pastes, oils.

* The quantity of the suctioned product depends on its properties and the
features of the installation. Please, contact INOXPA technical department to select auxiliary pumps.

It is important to keep low pressure at the suction and at the dishcrage sides of the blender and avoid cavitation. Thus, a feeding pump must be provided only for the applications that really require it (considerable pressure drops at the suction side, high viscosity products, etc.), please, keep in mind that the suction capacity will decrease.

When discharge pressure is high, a centrifugal pump needs to be fitted to the discharge side of the blender. For viscosities above 500 cP, the feeding pump and the discharge pump must be positive displacement pumps
