Mixing equipment has been shaped by years of real production use, not just design theory. The goal has always been smooth, even blending that keeps materials intact and results consistent. That practical experience shows up in machines made to work reliably day after day.

A double cone blender is a rotating vessel designed to mix dry powders and granules gently. As it turns out, the material splits and recombines inside the cone, creating an even blend without using internal agitators. This simple motion helps protect fragile ingredients while keeping the mixing process consistent and easy to clean.

GEMCO
Year Founded: 1943
Main Products:
- Double Cone Mixers and Blenders.
- Slant Cone Blenders.
- Tumble Dryers.
- GEMCOMATIC Material Handling System.
- Industrial mixing equipment for batch processing.
GEMCO is in Southington, Connecticut, and it is a family business that has been running for a long time. Five young guys started it in 1943 in Plantsville, Connecticut, and they named it General Machine Company at first. They shortened the name to GEMCO Manufacturing Co. Inc. after World War II so nobody would mix them up with other shops.
In 1948, the crew moved the whole operation to a bigger spot in Southington to keep up with work. Moving really helped them get set up as a trusty supplier for the area. They kept growing and now everyone knows their name.
It is pretty wild that this company actually invented the Double Cone blender design back in the 1930s. That specific shape changed how the industry mixes things because particles move easily without needing extra baffles inside. The design is low, so it fits in rooms with low ceilings, which factories really love.
The double cone vessel uses a simple idea where materials get split and put back together over and over. As the cone spins, it makes a smooth mix without dead spots where powder could get stuck. You get blend variations as low as 1 or 2 percent, which is perfect for exact jobs.
Mark DiVenere is the President right now, and he is the grandson of Dominic DiVenere, who was one of the five founders. It shows they care about keeping it in the family and saving that history. They build gear for over 40 industries, including pharma and powdered metals, so they have seen everything.
Charles Ross & Son Company
Year Founded: 1842
Main Products:
- Double Cone Tumble Blenders (Model DCB).
- V-Cone Blenders.
- High Shear Mixers.
- Double Planetary Mixers.
- Dispersion Equipment and Drying Equipment.
- Vacuum Jacketed Blenders.
- Custom Pressure Vessels and Reactors.
Charles Ross & Son Company has its main office in Hauppauge, New York, and it is one of the oldest equipment makers in North America. The business goes all the way back to 1842 in Rochester, New York, where two brothers named John and Charles opened a bakery and mill. The history is kind of crazy because Charles eventually moved the milling business to Brooklyn just to save cash on shipping stones.
The business became a formal company in 1900 with Charles and his son as the owners. Charles passed away that same year, so his son took charge and led them through big changes in the early 1900s. They managed to get through the 1903 recession and a banking crisis in 1907, which proves they are tough.
Their double cone tumble blender is a key product and they built it for mixing big piles of solids. It works by tumbling the stuff gently, so it doesn’t break fragile bits or ruin the batch. This matters a lot if you are mixing things that are rough or break easily.
The way it works relies on gravity to let the material fall as the vessel spins. This moves even the smallest ingredients through the whole batch. It makes sure everything mixes perfectly without needing complicated parts inside.
The company has been around for over 183 years. Now, they have eight plants across the United States, China, and India. In 1999, they switched to an employee stock ownership plan, which means the workers actually own part of the company. This helps keep the business in good hands for the future.
Kason Corporation
Year Founded: 1926
Main Products:
- Marion Double Cone Blenders (0.25-75 cubic feet capacity).
- Double Cone Solid Blenders (5L-10,000L configurations).
- High-Grit Finish Double Cone Blenders.
- Sterilizing and Drying Double Cone Configurations.
- Replacement Screens and Aftermarket Parts.
- Custom-Engineered Double Cone Units.
Kason Corporation is based in Newnan, Georgia, and it is a family company that just hit the 100-year mark. An immigrant from Eastern Europe started it in 1926 in Brooklyn with almost no money in his pocket. He started with a small store but took a chance to make a part for refrigerators, and that is how the factory side started.
Over time, they switched from making simple hardware like hinges to building big processing machines. They bought the Marion line of equipment, which is where they get their double cone blenders. These blenders use a gentle tumble that is perfect for mixing free-flowing solids that are about the same size.
You can find their machines in food and ceramic plants because they just work. They make 12 different models of these blenders, from small ones for labs to huge ones for big factories. The design has no moving parts inside, so it is super easy to clean when you are done.
Kason cares about fit and finish so you get a machine that lasts without paying too much. They also keep a lot of replacement parts and screens, so if something breaks, you aren’t waiting forever. They can ship these parts around the world pretty fast.
Paul O. Abbe
Year Founded: 1911
Main Products:
- Rota-Cone Double Cone Blenders.
- Rota-V Blenders.
- CrossMix Fluidizing Mixers.
- Ribbon Blenders and Paddle Mixers.
- Vacuum Dryers.

Paul O. Abbe is located in Wood Dale, Illinois, and they have been in the game for more than 110 years. Paul O. Abbé started the shop in 1911 in Little Falls, New Jersey, to make mills for the silk trade. They did really well with pigments early on, which gave them the cash to expand into other equipment.
One of their main claims to fame is the Rota-Cone double cone blender. This machine uses a tumble method to mix solids without using force, so it is very gentle. This is great for delicate stuff that would get ruined in a rougher mixer.
Since there are no agitators inside the vessel, you never have to worry about seals leaking. The design lets you check and clean the inside easily without taking the whole machine apart. This saves a ton of time on maintenance compared to other styles.
They make these blenders in all sizes, from small pilot models to full production units. You might see them being used to mix fertilizer or even fancy medicines. They also have a machine called the CrossMix that can blend solids in just a few seconds, which is fast.
The main office in Illinois handles all the engineering and support to keep things running. They are also members of a bunch of trade groups, which shows they take the science of mixing seriously. It is not just about building machines for them; it is about understanding the process.
INOXPA
Year Founded: 1972
Main Products:
- Double Cone Solids Blender (MBC series).
- V-Cone Blenders.
- Powder Handling Systems.
- Automated Double Cone Blenders.
- ATEX Certified Explosive Atmosphere Models.
INOXPA sits in Banyoles, Girona, Spain, and operates as a big engineering firm with offices on several continents. A guy named Candi Granés started it back in 1972 as a small factory making water pumps. From those small roots, they grew into a global leader in making stainless steel gear for food and wine.
Their main mixing unit is the MBC series double cone blender, built specifically for mixing solids. These machines come in sizes from 160 liters all the way up to 4,200 liters. You can use them to mix anything from coffee beans and soup mix to plastic pellets.
The blenders have special deflectors inside that help mix things evenly without crushing the product. This is key when you work with fragile stuff that needs to stay whole. INOXPA has factories in Spain, Portugal, and India, so they can build machines close to where people need them.
They also offer high-tech features like automated recipes and safety rails. If you need it, they can customize the machine with vacuum systems or automatic loading. Their engineering team works right with you to make sure the machine fits the job.

- Mucon Iris Diaphragm Valves.
- KEK Size Reduction and Classification Equipment.
- Tourell Confectionery Equipment (Chocolate Conches, Praline Cookers).
- Complete Mixing Stations.
Kemutec is a UK-based maker centered in Macclesfield and St Blazey, Cornwall. Even though the name Kemutec started in 1983, their history actually goes back to 1860 through the Gardner brand. William Gardner & Sons were engineers in Gloucester who were some of the first people to ever build mixing machines.
The business went through a few owners before becoming independent again in 1987. A group of managers bought the company so they could focus strictly on powder processing. This focus helped them refine their double cone blenders into really solid machines.
The Gardner double cone blender uses a gentle gravity tumble that works for fragile and rough stuff alike. Inside, there are plates that help mix the product as it flips over. It makes sure you get a good blend without working the material too hard.
All the bearings and supports are mounted on the outside of the machine. This means there are no seals inside the mixing area, which keeps things clean. It is much easier to wash out and stops batches from mixing together.
You can get these blenders in sizes ranging from tiny 2-liter lab units to massive 10,000-liter machines. They are used for delicate tea leaves, coffee, and even heavy metal powders. The company employs about 190 people and splits the work between their main office and the factory.
