Types of automatic maize grinding machines

The automatic maize grinding machine is a crucial part of the maize milling process. There are a few main types of maize grinders that are automatic for mass production.

• Hammer mill

  The automatic hammer mill grinder machine for maize is a versatile option. It uses impact forces to break down maize kernels into flour of various particle sizes. The adjustable screen plates allow operators to control the coarseness or fineness of the ground material easily. The hammer mill has high-speed rotating blades that chop the maize into small pieces. It works well for processing large volumes of grain, making it a suitable choice for commercial maize flour production.

• Roller mill

  Automatic maize roller mills are commonly used in larger-scale milling operations. They work by crushing and grinding the maize between two or more cylindrical rollers. The design easily separates the germ, bran, and endosperm parts of the maize. The roller mill may also use high temperatures to enhance the separation process further. The automatic feeding system controls the flow of maize to the rollers. This helps manage the production of maize flour, corn flour, and other byproducts.

• Disc mill

  Grinding maize using disc mills is another popular automatic option. The maize grinder machine has two flat discs that crush the grain between them. Normally, one disc spins while the other is stationary. There are adjustable features on the device that allow operators to manage how fine or coarse the ground maize is. Because they produce less noise and require less energy to operate, disc mills work well for smaller-scale milling businesses.

Specifications & Maintenance

The efficiency of maize mills depends on various specifications. The key ones are grinding capacity, precision, technology, and energy consumption.

• The grinding capacity of maize grinding machines for home use is 404-614kg/hr. commercial maize grinding machines have a higher grinding capacity. For example, the 50T-D maize flour milling machine has a grinding capacity of 25,000 kg per day. Larger commercial mills use the 1500T maize mill capacity per day.
• Automatic maize grinding machines must have precise settings to control the grain-to-flour ratio. A higher ratio increases profit, but customer retention is all about quality. The flour must have a fine texture. Some machines can adjust the ratio according to customer requests.
• Advanced automatic maize grinding machines use different technologies. A few employ stone crushing methods, while the majority use roller and impact crushing techniques that produce fine flour. More advanced machines have a pneumatic conveying system to move the grains internally with air pressure. It reduces the crushing gaps between rollers, and the flour produced is of better quality.
• Automatic maize grinding machines should ideally consume less energy and have better output. Some newer technologies use inverter motors to roller mills. They adjust the speed according to the amount of grain being processed, which saves energy expenses.

Regular inspection and repair of high-impact parts are required to keep the machine running smoothly. Routine checks include the mill, feeding system, grease cups, clutch, bearings, air system, motors, cleaning system, and sealing system. Some maize grinders use teeth to grind corn. Their teeth must be checked and changed frequently so that customers receive according to expectations.

Using only a small amount of high-quality food-grade lubricant on grease cups and chains is recommended. If a clutch is worn out, it should be replaced to improve the motor's and grinding parts' performance. All drive and air pipes need a thorough inspection to check for any wear-and-tear or clutches that need replacement. Electrical systems should be inspected for short circuits, loose connections, and other problematic areas that need repair. The entire air system requires inspection for leaks, blockages, pressure gauges, and more.

Centrifugal fans in the maize flour grinding machine should be cleaned of dust and debris every month. The housing, impeller, bearings, and intake and exhaust pipes should be cleaned properly. The axial fans must be cleaned every six months. All parts should be cleaned, and the bearing-play should be checked before putting it back together.

With routine maintenance and repairs, an automatic maize grinding machine can last a decade or more.

Scenarios of an automatic maize grinding machine

The scenarios for an automatic maize grinding machine showcase its essential role in processing maize into various products. Flour mills rely on these machines to produce different types of maize flour, meal, or grits, which serve as key ingredients for baking, cooking, and other culinary purposes. The seamlessly integrated maize mill machines process large volumes of maize kernels into maize flour with minimal supervision, increasing productivity.

In rural areas and small-scale businesses, an automatic maize grinding machine is also crucial at the local level. They produce maize flour, cornmeal, or grits for direct sale to nearby communities. These machines offer affordable and readily available maize processing solutions to corn farmers turned entrepreneurs. Feed manufacturers use the automatic maize grinding machine to produce animal feed. Different farm animals have different dietary needs; therefore, they require various feed types. The manufacturers also aim at enhancing their growth rates. Some types of feed are made from whole maize grains, while others may use ground maize kernels mixed with additional grains and supplements. In such a scenario, the automatic maize grinding machine assists the manufacturers in achieving the specified feed requirements for different animals.

Some commercial kitchens, restaurants, and food processing companies rely on the maize grinding machines to produce their own maize flour for baking, cooking, and other food preparation tasks. The advantage of using an automatic maize grinding machine is the consistency and quality of the maize flour. Moreover, the kitchen can choose the preferred coarseness of the flour depending on what they are making.

Sometimes, research and educational institutions might use the maize grinding machine for various studies, demonstrations, or educational purposes. The scenarios of the automatic maize grinding machine illustrate just how versatile it is in its applications. These machines offer processing solutions in commercial, agricultural, and educational settings.

How to choose automatic maize grinding machines

When deciding what kind of maize mill to buy for resale, people may want to consider how the machines operate. Small automatic maize grinding machines aren't that hard to operate because they come with an instruction manual. They might have a simple control panel with buttons and switches for milling various grains. Users may start pressing buttons to get the desired grain output. People may be interested in buying machines with digital control panels that allow users to set parameters like milling speed and fineness precisely.

People looking to purchase maize milling machines for resale should consider the power source. Grinding machines powered by electricity are quite common in industrial settings, but people also find them useful for home use. Stand-alone machines powered by diesel engines are convenient in remote areas with no electricity. Gasoline-powered mills are great for short-term projects requiring mobility and portability. Petrol-powered machines are easier to start than diesel, but the engine may wear out faster. The automatic maize grinding machine's production capacity is another thing to look at.
