ML series paddle mixers

Paddle mixer series ML is designed for mixing liquids and solutions without the presence of solid insoluble inclusions larger than 5 mm, with dynamic viscosity not exceeding 400-1000 cP, and temperature not higher than 90°C.

All parts of the mixer that come into contact with the product are made of stainless steel AISI 304 (equivalent to 12Х18Н10Т).

Operating conditions:

• ambient temperature not exceeding 40°C;
• relative humidity not exceeding 80%.

The paddle mixer ML consists of the following main parts (see the diagram):

1 — electric motor, 2 — worm gear reducer, single-stage, 3 — support flange with shaft sealing, 4 — shaft, 5 — impeller.

The operating principle of the mixer is based on transmitting torque from the electric motor to the impeller through a single-stage worm gear reducer. The reducer reduces the speed of the mixer shaft to the required level, while increasing the torque.

The mixer is driven by a three-phase asynchronous electric motor (pos. 1). The worm gear reducer (pos. 2) is single-stage and housed in an aluminum casing. The ML mixer has a support flange with shaft sealing (pos. 3), designed for mounting the mixer on a tank or special stand. The shaft (pos. 4) is hollow and made of stainless steel. The impeller blades (pos. 5) are positioned at a 45° angle to the shaft axis.

When the impeller rotates, the axial force directs the product being mixed down along the shaft axis and partially in the radial direction, ensuring proper mixing and preventing sedimentation at the bottom of the tank.

For poorly soluble and more viscous products (viscosity 2000-5000 cP), it is advisable to use two-level mixers with two rows of impellers, offset at a 45° angle.

Applications of Paddle Mixers

The paddle mixer has a simple and reliable design and is widely used in the chemical industry. It is essential not only for mixing liquid reagents but also in cases where the mixing agent is gas or air, as well as for mixing liquids and gases. Besides chemical production, paddle mixers are used in:

• the paint and coatings industry for the production of coloring compounds and colorants;
• the oil industry for mixing petroleum products;
• the pharmaceutical industry for creating various liquid medicines;
• the construction industry for making building mortars and mixtures.
