Raw coal extruder Coal powder coal slime processing coal rod machine for sale
The rotary drum coal rod machine, as an important equipment in the field of coal processing, uses the principle of spiral extrusion to skillfully compress the modulated pulverized coal into coal rods with specific strength and predetermined shape, playing a key role in many industries.
1. Working Principle
The motor power is transmitted to the transmission through the V-belt, and the transmission output shaft uses the floating coupling to accurately transmit the power to the propulsion shaft. The propulsion device on the propulsion shaft plays a role in pushing the coal forward, so that it can be smoothly pushed out through the forming die head, thereby producing an ideal high-pressure coal rod. In this process, the rotating impeller brings the coal particles falling vertically from the horizontal stirring into the rod machine and presses them into the groove of the shrinking barrel. Because the coal particles are sticky, the friction between the rotating coal particles and the stationary coal slime generates resistance, which prompts the rotating coal slime to transform into a linear motion along the groove of the shrinking barrel. Part of the coal slime is displaced along the inner normal direction on the compression surface of the impeller, and part of it forms static pressure between the groove of the shrinking barrel and the working gap. As the impeller rotates step by step, the coal slime continues to move forward, and the pressure at the head of the machine rises to the highest. When the pressure exceeds the pressure loss along the rod hole of the machine head, the coal slime is squeezed through the rod hole.
2. Structural design
1. **Core components**: The internal impeller adopts a thickened blade design, combined with wear-resistant precision casting materials, which greatly improves the wear resistance. Compared with ordinary materials, the service life is extended by 4-5 times. The inner lining of the cylinder is also made of wear-resistant precision casting materials to effectively reduce the friction loss between the material and the cylinder. The coal rod outlet at the head of the machine is made of replaceable wear-resistant alloy steel, which is convenient for timely replacement after wear to ensure the continuous and efficient operation of the equipment. 2. **Overall structure**: The shaft seat and the cylinder body are rigidly connected, which greatly improves the concentricity, enabling it to effectively resist the reverse thrust and ensure the stability of the machine operation. The sealing part of some models adopts a fault structure, and the dirt can be leaked from the fault, reducing the risk of equipment failure. At the same time, the connection between the head and the cylinder body is diverse, including a clamping ring structure, a bolt structure, etc., which can be flexibly selected according to the actual needs of the user.
3. Performance advantages
1. **High efficiency and energy saving**: The feed spiral pitch is large, the feed speed is fast, and the propulsion spiral pitch is small, which saves power consumption while ensuring production efficiency. Equipped with a hardened gear reducer, it is not only small in size, but also has a high load-bearing capacity, which further optimizes energy utilization efficiency.
2. **Sturdy and durable**: Key components are made of high-quality materials, such as the cylinder body is made of high-strength steel, which can withstand long-term and high-intensity workloads, reduce the frequency of equipment maintenance, reduce the cost of use, and extend the overall service life.
3. **Stable operation**: The V-belt transmission method makes the equipment run smoothly and with low noise, and when encountering overload conditions, the V-belt can play an overload protection role to prevent the equipment from being damaged due to overload, ensuring the continuity and stability of the production process.
4. Applicable materials and application scenarios
1. **Applicable materials**: It has good adaptability to various types of coal powder, such as anthracite, lignite, coking coal, etc., as well as powdered materials such as coal gangue, iron powder, and aluminum powder, and can be efficiently processed into coal rods.
2. **Application scenario**: In the gasification system of nitrogen fertilizer plants and gas plants, it is the core equipment of the complete set of fuel molding equipment. By squeezing pulverized coal into coal rods, it provides high-quality fuel for the gasification furnace, replacing the traditional lump coal and coal ball gasification process. At the same time, in the briquette plant, it can be used to produce briquette products of different specifications; in some industrial fields where powdered materials need to be molded, such as some metallurgical and chemical industries, it can also play an important role.
The rotary drum coal rod machine has become a reliable choice for material molding in coal and related industries with its unique working principle, sophisticated structural design, and excellent performance advantages, providing strong support for improving production efficiency, reducing costs, and promoting industry development.
