Double conical mixers are available in different types classifying based on their operational characteristics, construction materials, and design features.
S hearing mixers:
The stirring type double cone mixing machine employs a stirring paddle or propeller to blend or mix various materials. The stirring paddle is powered by an electric motor to generate rotation, which may make the materials in the mixer cone go round and move up and down, thus achieving uniform mixing.
Oxygenation mixers:
The double cone oxygenation mixer works by introducing bubbles to the mixer cone through an aeration diffuser. The process creates mixing by moving the bubbles through the material, improving material homogeneity.
Stainless Steel:
It is a double cone mixer machine manufactured fully out of stainless steel. It is applicable in industries that adhere to high levels of cleanliness and hygiene.
Carbon Steel:
It is a double conical mixer made out of carbon steel and is ideal for use in industries that do not demand strict standards for material mixing. Carbon steel is more robust and less expensive than stainless steel, making it more appropriate for low-budget or non-specialized uses.
With Agitators:
The agitator-equipped double-conical mixer features an additional agitator inside the cone in addition to the conical mixing chamber. This inner agitator may take the shape of a paddle, a screw, or any other suitable design. It improves the mixing effect of the mixer and raises the uniformity of mixed materials.
Without Agitators:
The double-conical mixer without an agitator means that the mixer has no internal agitator. This kind of mixer usually relies on the conical structure to turn the material and achieve mixing. Mixers without agitators are suitable for materials that are easy to mix, and the mixing speed is relatively fast.

Business buyers can use the following ideas to help them choose the right double cone mixer for their processes and applications.
Understand the supply needs and material characteristics
Companies should first understand their supply needs by considering the batch size, mixing capacity, and supply frequency that are suitable for their processes. They should also evaluate the material characteristics of the materials to be mixed, such as particle size, bulk density, flowability, and whether they are fragile or not. If they have special requirements, like being in an explosive or toxic environment, your materials may need to be an explosion-proof double cone mixer or one with certain sealing features.
Efficiency and energy-saving
Choose a double cone mixer with suitable power and speed settings. A more efficient motor can help save energy and operating costs. Check whether the equipment has energy-saving modes, such as low-power or standby.
Flexibility and scalability
Consider the flexibility and scalability of the double cone mixer. Does it support mixing different kinds of materials? Can it be upgraded or modified to meet future needs?
Machine quality and maintenance
Select machines with good-quality, durable materials, like stainless steel, that offer long service lives. Evaluate the maintenance procedures and spare parts availability to ensure the double cone mixer can be maintained for a long time and operate continuously.
Safety and environment
Ensure that the double cone mixer selected complies with relevant safety standards and has necessary safety features, like overload prevention and emergency stop buttons. Check whether the equipment has energy-saving and environmentally friendly features, like low noise and waste reduction.
Service and support
Consider the brand and manufacturer of the double cone mixer. Choose a manufacturer that provides comprehensive technical support and services. They should offer timely maintenance and repair services to ensure the equipment operates well.
Q1: Is there any difference between double cone mixer and double cone powder mixer?
A1: No, these terms refer to the same machine.
Q2: What materials can be used with a double-cone mixer?
A2: The material must consider such factors as temperature sensitivity, cohesion, and particle size. It must be suitable for the mixer's capacity and construction to ensure no contamination or adverse reactions.
Q3: Can a double-cone mixer be used for materials other than powders?
A3: Yes, but only if materials are non-powder ones. They are not beyond the capacity and construction limits of the double-cone mixer. Irrespective of the type of mixer being used, the material must be of suitable consistency to enable effective mixing.
Q4: How does the efficiency of a double cone mixer compare to other types of mixers?
A4: Double cone mixers are generally more efficient than horizontal paddle mixers and less so than high-shear vortex mixers, which are better for emulsifying and homogenizing. Efficiency also depends on the material and mixing goal.
Q5: Are double-cone mixers hazardous?
A5: If proper safety precautions are not taken during operation, double-cone mixers may pose some risk, such as explosion, fire, chemical hazard, etc. This is because the double cone mixer can sometimes be prone to static electricity, which may cause an explosion. To prevent any such risks from arising, static electricity grounding, bonding, and dissipation should be ensured; equipment maintenance and housekeeping should be done to minimise any dust accumulation; the volumetric dust extraction system, which is used only in closed parts of the mixer, should never be used in open ones, etc. Safety data sheets and system operating manuals should always be referred to for more information and safety procedures.
