Tube grinder

Types of tube grinders

A tube grinder is a device that improves productivity and saves time by grinding materials in tubes. The main types of tube grinders are as follows.

• Blade tube grinder:

  This grinder has a circular blade that runs at high speed. It cuts or slices through the materials placed in the tube. The blade tube grinder is suitable for grinding hard and dry materials, such as spices and nuts. The blades are sharp and strong, ensuring a fine and even grind. The blade tube grinder is easy to use and clean. However, users must be careful not to overload it. Otherwise, the motor may burn out.

• Burr tube grinder:

  The burr tube grinder uses two revolving abrasive wheels or burrs to crush the materials. This grinder can adjust how fine or coarse the grinding is by changing how far apart the burrs are. Burr grinders are often used for coffee beans because they can grind at different sizes. Some models have a setting for grinding coffee and another for grinding spices. Burr grinders are good because they make less noise than other grinders, and everything stays in the tube, making less mess.

• Ball tube grinder:

  The ball tube grinder is a kind of tube mill. It is used to grind materials like cement and coal. The working principle is similar to a ball mill. Steel balls inside the grinder crush and grind the material. It keeps grinding until the powder is very fine. This machine is efficient and suitable for making a lot of cement. It uses less energy and works continuously. The fineness of the ground material can be controlled by changing the time or amount of material.

• Rod tube grinder:

  In a rod tube grinder, the grinding elements are steel rods instead of balls. The rods are of different lengths and are placed loosely in the tube. When the tube moves, the rods slide and roll against each other and against the material, crushing and grinding it. This grinder is good for bigger pieces of material that need to be crushed or ground. It works well with ores and rocks. It reduces wear and tear on the machine parts. The output size is uniform, which is good for further processing.

• Hammer tube grinder:

  A hammer tube grinder has many small hammers attached to a fast-spinning shaft. The hammers hit the material repeatedly until it is crushed into small pieces or powder. This machine can quickly grind hard things like bones, ores, and spices. The grinding speed is adjustable by changing how fast the shaft spins. It is suitable for grinding wet or dry materials and can be used in different industries.

Design of tube grinders

Tube grinders are designed with multiple parts working together to achieve the desired grinding results. Some of these parts include the following:

• Drum:

  The drum is the main body of the grinder. It houses all the internal parts, including the grinding mechanism. Drums come in various sizes and capacities to accommodate different needs.

• Grinding mechanism:

  Tube grinders use various grinding mechanisms, including blades, hammers, and burrs. Blades cut materials into smaller pieces, while hammers crush them. On the other hand, burrs mash substances into finer particles.

• Feeding hopper:

  This is an opening at the top of the tube grinder where materials enter the drum for grinding. Feed hoppers can be manual or automatic. They are designed to hold large quantities of materials before feeding them into the grinder.

• Discharge chute:

  Like any other piece of equipment, tube grinders have a part designed for discharging the finished product. The discharge chute is an opening at the bottom of the grinder that allows the ground materials to flow out of the drum. Some grinders have a bagging system attached to the discharge chute for collecting ground materials.

• Motor:

  The motor is an essential part of the tube grinder. It provides the necessary power to operate the grinder. Motors come in various power ratings depending on the size and capacity of the grinder. Tube grinders can be either electric or fuel-powered.

• Frame and casing:

  The frame supports all the structural components of the tube grinder. It is usually made of sturdy materials like steel to withstand vibrations during operation. Casing covers and protects all the internal parts from external elements such as dust and moisture. It also helps contain noise produced during grinding.

• Control panel:

  The control panel is where all the operations of the tube grinder are controlled. It usually has buttons for starting or stopping the motor, adjusting the speed, and switching between different modes of operation.

• Safety features:

  Like many other machines, tube grinders can be dangerous if not handled properly. They are fitted with various safety features to prevent accidents and ensure the safe operation of the grinder. Some common safety features include overload protection, emergency stop button, and guard covers.
