Choosing a gypsum board mixer requires comprehensive consideration of material characteristics, production efficiency, equipment performance, and long-term maintenance costs. Here are the key purchasing points, combined with industry experience and professional advice:
1、 Core parameter matching
Power and speed
Power: Gypsum board raw materials (gypsum powder, additives, etc.) require a large torque for mixing. It is recommended to choose a motor of ≥ 700W (reference, ensure sufficient mixing power, and avoid clumping or low efficiency due to insufficient power).
Speed: Priority should be given to brushless motors (reference, low speed can be adjusted to 30-50 revolutions per minute, high speed gear meets the needs of fast mixing, avoiding high-speed splashing or uneven mixing at low speeds).
Mixing structure design
Concentricity: Choose a synchronous wheel+mixing shaft structure (non directly connected motor) to ensure high concentricity of the mixing rod (reference, reduce vibration and material stratification).
Dead corner control: The design of the mixing blade should cover the edge of the tank, with a dead corner rate of less than 5% (reference, to prevent gypsum deposition and agglomeration).
2、 Key component performance
Motor Type
Brushless motor: low noise, maintenance free (no need to replace carbon brushes), long lifespan (reference, suitable for long-term continuous production).
Carbon brush motor: only suitable for budget limited and intermittent use scenarios, but requires regular maintenance.
Blade and mixing blade
The blade should be made of 4-5 pieces of stainless steel material (reference, considering both crushing power and corrosion resistance); the mixing blade should be adapted to the viscosity of gypsum, and it is recommended to use a spiral belt or anchor design.
3、 Durability and Extended Functionality
Material and Protection
Contact parts (clamps, bearing seats) require stainless steel or anti-corrosion coating (reference, resistant to weak acid corrosion of gypsum).
The bottom plate is thick and the upright pole is sturdy, which enhances the stability of the equipment.
intelligent control
Multi speed regulation (referring to different ratios of raw materials; timing function to avoid gypsum hardening caused by excessive mixing.
4、 Guide to Avoiding Pits
Careful selection of direct connection motor structure: The small size of the machine head and poor concentricity of the direct connection equipment can easily cause the mixing shaft to shift (reference).
Avoid low-power models:<500W motors are difficult to handle gypsum powder and may burn out the motor (comprehensive).
&Operation suggestion: For small and medium-sized production, choose a 700W brushless motor+synchronous wheel structure model; Large scale assembly lines require customized high-power (≥ 1.5kW) equipment and the installation of an automatic feeding system. When making actual purchases, suppliers can be requested to provide gypsum powder mixing test data to verify mixing uniformity and energy consumption.
