Gypsum Powder Double Ribbon Mixer is a horizontal powder mixing machine for mixing gypsum powder. It is optimized for materials such as building gypsum, desulfurized gypsum, and gypsum-based putty powder, which are fine, easily powdered, and easily adhered to the surface. It employs a double-layer counter-current double-screw mixing structure, with the outer layer collecting material and the inner layer feeding, creating bidirectional convection shearing of the material. It can meet the production capacity requirements of multiple specifications with a single feed, and the mixing time is 10-25 minutes, quickly completing the mixing of gypsum powder with binders, additives, and other auxiliary materials. We support customized production based on your production capacity, processing conditions, and supporting requirements. Flexible options are available for materials, unloading methods, dust collection and sealing, frequency conversion control, etc., to create a tailor-made gypsum powder mixing solution.
The Gypsum Powder Double Ribbon Mixer utilizes a double-ribbon counter-current convection mixing system, resulting in high mixing efficiency. It supports customized configurations to adapt to different production capacity needs, making it an essential supporting equipment for gypsum powder processing.
High mixing uniformity: The forced convection shearing mechanism effectively solves the stratification problem caused by differences in material specific gravity and fineness, ensuring stable performance of each batch of finished gypsum product.
Fast mixing speed: Compared to other ordinary mixers, it has a shorter mixing cycle, suitable for continuous, high-volume production.
Handles solid-liquid mixing: While mixing dry powder, a small amount of water or liquid additives can be precisely added through a spray system to achieve preliminary wetting and mixing, providing ideal semi-dry material for subsequent processes.
Clean discharge: The bottom is typically equipped with a large-opening pneumatic or manual butterfly valve, ensuring smooth discharge without residue and facilitating cleaning.
The Gypsum Powder Double Ribbon Mixer is a horizontal, integrated structure, consisting of a U-shaped cylinder, a double-ribbon mixing system, a drive system, and a discharge system. The U-shaped cylinder features a rounded transition with no dead angles and a smooth inner wall to prevent material buildup. The core double-ribbon design uses a double-layer reverse mixing mechanism: the outer layer collects material, and the inner layer feeds, complemented by a thickened through-shaft. The drive system consists of a variable frequency motor and a reduction gear, with double-layer sealing to prevent dust ingress. An arc-shaped discharge port at the bottom, equipped with manual/pneumatic valves, ensures thorough discharge with minimal residue.
The Gypsum Powder Double Ribbon Mixer uses a horizontal double-ribbon reverse mixing principle. After startup, the variable frequency motor drives the horizontal through-shaft to rotate via the reduction gear, causing the double-layer ribbons inside the cylinder to rotate synchronously in the opposite direction. The outer spiral ribbon gathers gypsum powder and additives from both ends towards the center of the cylinder, while the inner spiral ribbon pushes the material from the center towards both ends, creating bidirectional convection and shearing agitation of the gypsum powder, ensuring thorough mixing of the fine gypsum powder and various additives.

A new building materials company specializing in the production of gypsum mortar and gypsum putty powder previously experienced product quality fluctuations due to severe material buildup in its mixing equipment and uneven mixing of gypsum powder and additives. They purchased our custom-made 304 stainless steel double spiral ribbon gypsum powder mixer, with a single batch mixing capacity of 3 tons. The counter-current convection mixing of the double spiral ribbons ensures thorough material blending, achieving a mixing uniformity of over 98%, with a smooth inner wall free of material buildup and extremely low residue after discharge. The equipment's mixing time is only 6 minutes, with a daily output of up to 30 tons.
Gypsum powder is fine, easily powdered, and prone to sticking, making the double ribbon mixer significantly superior in mixing efficiency and uniformity. It employs a double-layer counter-current convection design, with the outer layer collecting material and the inner layer feeding, creating bidirectional tumbling and shearing of the material, eliminating mixing dead zones and allowing the gypsum powder and additives to fully blend. A single ribbon mixer only pushes and stirs in one direction, making material accumulation more likely during the mixing process. Furthermore, the mixing efficiency of the double ribbon model is also higher than that of the single ribbon mixer.
The Gypsum Powder Double Ribbon Mixer supports a variety of customized optional configurations, covering aspects such as material selection, unloading, control, dust prevention, and auxiliary devices, which can be selected to suit specific production conditions.
Discharge Configuration: Manual butterfly valve or pneumatic butterfly valve. The pneumatic version supports automated control, improving feeding and discharging efficiency.
Material Upgrade: The cylinder and screw ribbon can be made of carbon steel or 304/316 stainless steel. The stainless steel version is corrosion-resistant, easy to clean, and suitable for mixing food-grade gypsum powder or wet auxiliary materials.
Variable Frequency Control: Equipped with a variable frequency speed control motor, allowing flexible adjustment of the stirring speed to meet different gypsum powder mixing requirements.
Auxiliary Devices: Optional screw conveyor, weighing and batching system, and insulation jacket for integrated feeding-mixing-discharging.
The Gypsum Powder Double Ribbon Mixer manufactured by DaHan Machinery starts at $500. The specific price will be adjusted according to customized requirements, such as upgrading to 304/316 stainless steel, adding a variable frequency control system, including a negative pressure dust removal device, and integrating an automatic weighing and batching system. Different configuration combinations correspond to different prices. As a direct manufacturer, we eliminate intermediaries, providing customized solutions while ensuring cost-effectiveness. We support bulk purchasing by global clients, offering a one-stop solution to meet their personalized production needs for gypsum powder mixing.
The Gypsum Powder Double Ribbon Mixer is a gypsum powder processing and mixing device. Its counter-current double ribbon mixing ensures uniform material mixing, eliminating dead zones and minimizing residue. It is adaptable to various production capacities and customized configurations.
