What is the feed size of HPGR?

HPGR stands for high pressure grinding rolls. It is a comminution technology that uses a high-pressure roller mill to reduce the size of ore particles, typically in the range of a few millimeters to a few microns. HPGR is often used as a more energy-efficient and cost-effective alternative to traditional grinding technologies, such as ball mills and SAG mills.

The HPGR consists of two counter-rotating rolls that apply high pressure to the ore particles as they pass between the rolls. The pressure applied can range from 50 to 400 MPa, depending on the specific application. The high pressure causes the ore particles to break or crack, reducing their size and creating a more uniform product with fewer fines.

High-Pressure Grinding Rolls

The feed size of HPGR (High Pressure Grinding Rolls) varies depending on the application and the specific machine used. In general, HPGR is designed to handle relatively large feed sizes compared to other grinding technologies, such as ball mills or SAG mills.

Typically, the feed size range for HPGR can vary from a few millimeters up to several centimeters, depending on the specific application. However, it is important to note that the maximum feed size is limited by the roll diameter and the gap between the rolls. In addition, the hardness and abrasiveness of the feed material can also impact the feed size that can be effectively processed by the HPGR.

WHAT IS THE PROCESS OF OPEN DIE FORGING

Open die forging, also known as smith forging or blacksmith forging, is a forging process where the metal is deformed between two flat or slightly curved dies that do not completely enclose the workpiece. The process involves the following steps:

Preparing the workpiece: The workpiece is heated to a temperature above its recrystallization temperature, which allows it to become malleable and easier to shape.

Master axis

Placing the workpiece on the anvil: The heated workpiece is placed on the anvil or the bottom die of the forging press.

Shaping the workpiece: The top die of the forging press is brought down onto the workpiece to shape it. The operator may also use hand tools, such as hammers or tongs, to shape the workpiece.

Reheating the workpiece: The workpiece may need to be reheated periodically to maintain its malleability and prevent cracking.

WHAT IS THE PRINCIPLE OF CYLINDRICAL CALCIUM-BASED DESULFURIZER

A cylindrical calcium-based desulfurizer is a material used in the desulfurization process of industrial gases, such as flue gas from power plants or waste incineration facilities. The desulfurizer is typically made of calcium oxide (CaO) or calcium hydroxide (Ca(OH)2), which react with sulfur compounds in the gas to form calcium sulfite (CaSO3) or calcium sulfate (CaSO4).

The principle of a cylindrical calcium-based desulfurizer is based on a chemical reaction between the desulfurizer material and the sulfur compounds present in the gas stream. The desulfurizer is typically made of calcium oxide (CaO) or calcium hydroxide (Ca(OH)2), which react with the sulfur compounds to form calcium sulfite (CaSO3) or calcium sulfate (CaSO4).

cylindrical desulfurizer

The cylindrical shape of the desulfurizer provides a large surface area for the gas to come into contact with the desulfurizing material, allowing for efficient removal of sulfur compounds from the gas stream. The gas stream is passed through the desulfurizer bed, and as it passes through the cylindrical desulfurizer, the sulfur compounds react with the calcium-based material.

The chemical reaction that occurs in the desulfurizer is typically an acid-base reaction, where the sulfur compounds present in the gas stream act as acids and the calcium-based material acts as a base. The reaction products, calcium sulfite or calcium sulfate, are solid materials that can be easily removed from the gas stream.

What is the principle of vibrating screen?

A vibrating screen machine is a device used to separate materials into different sizes or grades based on their particle size. The machine consists of a screen that vibrates at a high frequency and is used to separate solids and liquids, or solids of different sizes.

The vibrating screen machine consists of a frame, a vibrating motor or drive unit, and a screen. The screen is made up of a series of wire mesh panels that are arranged in layers to provide different levels of filtration. The vibrating motor or drive unit is responsible for generating the vibrations that cause the material to move across the screen.

Linear vibrating screen

The principle of a vibrating screen is based on the movement of a circular vibrating screen. The screen works on a circular motion, which is generated by an eccentric shaft. The vibrating screen is designed to vibrate at a specific frequency, which is achieved by adjusting the eccentric weights.

As the screen vibrates, the material is separated into different sizes. The larger particles move towards the top of the screen, while the smaller particles move towards the bottom. The screen consists of multiple layers of mesh, with the size of the mesh varying depending on the desired particle size.

The vibrating screen works by applying a vibratory force to the material being processed. The force is generated by an electric motor that is connected to the screen through a series of belts, pulleys, and gears. As the motor rotates, it causes the eccentric weights to move in a circular motion, which in turn causes the screen to vibrate.
