A concrete mixer (often colloquially called a cement mixer) is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. A typical concrete mixer uses a revolving drum to mix the components. For smaller volume works, portable concrete mixers are often used so that the concrete can be made at the construction site, giving the workers ample time to use the concrete before it hardens. An alternative to a machine is mixing concrete by hand. This is usually done in a wheelbarrow. According to the working nature, it can be divided into batch type (batch type) and continuous type; according to the stirring principle, it can be divided into self-falling type and forced type; according to the installation method, it can be divided into fixed type and mobile type; According to the structure of the mixing drum, it is divided into pear type, drum type, double cone, disc vertical shaft type and circular groove horizontal shaft type.
A mixing paddle is a shaped device, typically mounted on a shaft, which can be inserted on the shaft end into a motorised drive, for the purpose of mixing liquids, solids or both. Paddle mixers may also be used for kneading. Whilst mounted in fixed blending equipment, the paddle may also be referred to as an agitator. Mixing paddles are used for mixing ingredients in cooking and for mixing construction products, such as pastes, slurries or paints. They are also used for dispersing solids within liquids (for example, some polymers may be delivered in solid form, but will dissolve in liquids). It has the following characteristics: 1. The anchor type and frame type are generally used at low speed between 60 and 300rpm. This is because considering the length of the anchor type and frame type is 3 to 5 meters, the support point is located at the shaft head, and the stirring shaft is The strength is limited, and the stirring shaft beats relatively large at high speed, especially the shaking at the bottom of the stirring range is large, and even touches the inner wall of the reaction kettle. At the same time, the number of revolutions is selected in combination with the viscosity of the material. The viscosity is large and the speed is low, and the viscosity is small and the number of revolutions is an appropriate high point; 2. Turbine type: There are many blades, many types, and high speed, so that the fluid can be changed from vertical movement to horizontal movement evenly; 3. Propulsion type: The propulsion type is also called the propeller type. It is often cast as a whole. When welding is used, it is difficult to process the shaft sleeve after die forging. The static balance experiment should be done during manufacture, and the shaft can be connected with the shaft sleeve, flat key and set screw.
