Detailed analysis of the advantages of double-shaft mixers from the perspective of structure, process and core technology

The double-shaft mixer (also known as the twin-shaft mixer) is the core equipment for efficient mixing of powder, granules and viscous materials in the building materials, chemical, metallurgical and environmental protection industries. With its bidirectional stirring force and uniform mixing effect, it has become an irreplaceable key link in the production line. This article will analyze the advantages of the twin-shaft mixer in depth.

Advantages of double-shaft mixers:

1. Advantages of the core structure of the double-shaft mixers:

The main components include: twin stirring shaft system, transmission device, mixing tank body and unloading system. These precision structures jointly determine the good performance of the twin-shaft mixer.

2. Working principle of the double-shaft mixers and material movement analysis:

The twin shafts are driven by the reducer and rotate synchronously in opposite directions, driving the mixing blades to exert shear force, convection force and diffusion force on the materials, forming a three-dimensional composite movement. Material mixing process: feeding stage: the material is put in from the top feed port and evenly distributed at the bottom of the tank body. Shear dispersion: the counter-rotating blades push the material to the middle of the tank body to form a high-density interaction area. The relative speed difference between the blades and the material produces strong shear to break the agglomeration. Convection circulation: the outer blades push the material to move along the axial direction, and the inner blades throw the material in the opposite direction, forming an “8”-shaped circulation trajectory to improve the mixing uniformity (up to more than 95%). Discharging stage: after the bottom gate is opened, the blades continue to rotate to empty the mixture without residue.

Common faults and quick solutions of horizontal vibrating screen

As the core screening equipment in the mining, chemical, building materials and other industries, the stable operation of the horizontal vibrating screen directly affects the production efficiency. However, long-term high-intensity operation may cause equipment failure. This article summarizes the common faults of the horizontal vibrating screen and its professional solutions to help users quickly troubleshoot hidden dangers and reduce downtime losses:

Common faults and solutions of horizontal vibrating screen：

1. The equipment cannot start normally or suddenly shuts down:

The reasons for this problem include poor contact of the power line or unstable voltage, motor overload triggering protection, and vibration exciter bearing stuck. The solution is to check the power connection and test the voltage stability (it is recommended to be equipped with a voltage stabilizer), clean the material blocking the screen surface, reduce the motor load, disassemble the vibration exciter, and clean or replace the damaged bearing.

2. The screening efficiency is significantly reduced:

The key reasons for this problem are that the mesh size of the screen does not match the particle size of the material, the angle deviation of the vibration motor eccentric block (ideal angle: 45°~90°), and the insufficient tension of the screen surface leads to local relaxation. To solve this problem, you can replace the polyurethane screen with a suitable mesh size according to the material characteristics, adjust the eccentric blocks on both sides to the same angle (synchronous and symmetrical adjustment is recommended) or use professional tools to re-tighten the screen to ensure uniform force.

Arc Vibrating Screen

3. Abnormal noise occurs when the equipment is running:

Common reasons include loose bolts causing component collisions, lack of oil in the bearings or aging of seals, or the screen is damaged and hits the support beam. The specific maintenance process is to fully tighten all bolts after shutdown (the torque must meet the equipment manual standard), add high-temperature lithium-based grease to the bearings (replenish once every 500 hours), immediately replace the damaged screen, and check whether the support beam is deformed.
