Mixer maintenance and principle and application of mixer

Pay attention to the following matters during normal work and maintenance:
① Be sure to perform according to the operating procedures of the equipment. This is a good maintenance of the equipment.
② Note that the equipment should be added and mixed after the equipment starts normally. The materials should be added slowly in the required order.
③ Prepare the seal ring, the rubber ring for the coupling, the V-belt and the rolling bearing. The working parts of these parts are prone to failure and should be replaced in time if necessary.
④ Periodically (generally one quarter) to check whether the fasteners are loose; check the tightness of the V-belt installation; all parts of the equipment should be cleaned and dusted.

Mixer repair can generally be performed once a year. Note the following:
① Check that the gap between the mixing paddle, scraper and the mixing chamber wall should meet the requirements in the table below.
②Remove each rolling bearing, clean and inspect; replace the worn parts. Replace grease and seals.
③ Check whether the main drive shaft is bent or worn.
④ Check the cleaning cylinder, replace the wearing parts of the seal ring and the guide sleeve, and check whether the piston rod is bent and deformed.
⑤ Make a record after checking the main parts, test if necessary, prepare the parts and accessories, and propose the next repair and replacement.
The above is the introduction of high-speed mixer maintenance and repair. Let me talk about the principle and application of the mixer.

Mixer is a machine that uses the effects of mechanical force and gravity to uniformly mix two or more materials. Hybrid machinery is widely used in pharmaceutical, food, chemical, agriculture, construction and other industrial production and daily life.
The mixer can mix a variety of materials into a homogeneous mixture. For example, in the pharmaceutical industry, the raw materials of different ingredients are evenly mixed together to form a compound. The surface area of the material can be increased to promote chemical reactions. It can also accelerate physical changes such as granular The solute is added to the solvent, and the dissolution and mixing can be accelerated by the action of the mixing machine.
Commonly used mixing machines are divided into four categories: gas and low viscosity liquid mixers, medium and high viscosity liquid and paste mixers, thermoplastic material mixers, powdery and granular solid material mixers.

Here mainly introduces the solid material mixer.
Most of the powdery and granular solid material mixers operate intermittently. At present, there are three types of mixers in the market: V-type mixer, three-dimensional mixer and trough mixer.
When mixing, all materials involved in the mixing must be evenly distributed. The degree of mixing is divided into three states of ideal mixing, random mixing, and completely non-mixing. The degree of mixing of various materials in the mixing machine depends on factors such as the proportion of the materials to be mixed, the physical state and characteristics, as well as the type of mixing machine used and the duration of the mixing operation.
Granular solids with good fluidity are mainly mixed by the container's rotation or by the moving parts installed in the container, which are repeatedly turned and blended. In this case, a V-type mixer is generally used.
Materials with poor fluidity and relatively large proportions are not sufficient by simple turning action. Multi-directional and multi-angle actions are required to achieve sufficient mixing. In this case, a three-dimensional mixer or a multi-dimensional mixer is generally used.
Granular or powdery solids with poor fluidity and adhesion to each other often require a mixer with mechanical turning, pressing, rolling and other actions. In this case, a trough type mixer is generally used.
