Cement Production Line Projects

ofcement production line segment equipment display:

1. Cement mill

◆ Product Description: All kinds of cement mills produced by Hongfa Heavy Industry are suitable for dry or wet grinding of various ores and other grindable materials in cement plants, refractory plants, chemical fertilizer plants and ferrous or non-ferrous metal concentrators.

◆ Working principle: Cement mill is composed of feeding hopper, rotating part, discharging part, main bearing part and transmission part. When the mill is rotating, the grinding body in the machine is attached to the lining plate and rotates with the grinding body due to inertial centrifugal force and friction force. After being taken to a certain height, it is thrown down due to its own gravity. The falling grinding body shatters the materials in the simplified body like a projectile.

2. Dryer

◆ Product introduction: The dryer is mainly used for drying materials with certain humidity or particle size in mineral processing, building materials, metallurgy, chemical industry and other departments. The rotary dryer has strong adaptability to materials, can dry all kinds of materials, and the operation of the equipment is simple and reliable, so it is widely used.

◆ Working principle: The machine is mainly composed of rotating body, material plate, transmission device, supporting device and sealing ring and other components. The dryer in our factory adopts a new type of material raising plate device, which has many functions such as guiding, equalflow, material raising, etc., so that the materials can be fully distributed in the radial section of the dryer, the material curtain becomes thin, uniform and complete, and completely contacts the hot air flow, thus achieving the purpose of making full use of heat energy.

dryer adopts downstream heating mode. Therefore, the materials that need to be dried slip into the barrel from the feed box and feed, I .e. pushed back by the spiral copying plate. Due to the inclined placement of the dryer, on the one hand, the materials flow to the rear end under the action of gravity and rotation, on the other hand, the materials are repeatedly picked up by the copying board, brought to the upper end and then continuously scattered, so that the materials form a uniform curtain in the barrel and fully exchange heat with the hot air flow in the barrel. As the materials are repeatedly scattered, the water contained in the barrel is gradually dried, thus achieving the purpose of drying.

3. Cement rotary kiln

◆ Product introduction: Cement rotary kiln is mainly used for calcining cement clinker, including: dry cement rotary kiln, semi-dry cement rotary kiln and wet cement rotary kiln. The raw meal powder is fed into the kiln cylinder from the high end of the kiln cylinder. Due to the inclination and slow rotation of the kiln cylinder, the material produces a compound movement that rolls along the circumferential direction and moves from the high end to the low end along the axial direction. The raw material is discharged from the low end of the kiln cylinder after firing cement clinker through decomposition, firing and other technological processes in the kiln.

◆ Technical features: The kiln body is made of high-quality carbon steel or alloy steel plate and automatically welded; the rolling ring is made of ZG35CrMo steel or 42CrMo steel. The large tooth is connected with the kiln cylinder through a tangential spring plate, and the sealing device structure adopts two categories: labyrinth type and contact type, and the contact type is divided into scale type, graphite block type, cylinder slip ring type and other forms. The system has good sealing effect, realizes full utilization of waste heat, environmental protection and dust removal, simple and effective, and truly realizes high clinker quality and low burning heat consumption.

4. Metallurgical rotary kiln

◆ Product introduction: Metallurgical rotary kiln is a thermal equipment for drying, roasting and calcining bulk or slurry materials. It is used in industrial sectors such as non-ferrous smelting, iron and steel metallurgy, chemical industry, cement and refractory materials, especially in non-ferrous smelting and refractory industry. The metallurgical chemical kiln is mainly used for magnetization roasting of lean iron ore in steel plants in the metallurgical industry; oxidation roasting of chromium and nickel iron ore; roasting of high bauxite ore in refractory plants and roasting of clinker and aluminum hydroxide in aluminum plants.

◆ Technical characteristics: The kiln body is made of high-quality killed carbon steel or alloy steel plate and automatically welded; the wheel belt, supporting wheel and open gear are made of alloy cast steel. The sliding bearing adopts large clearance non-scraping bearing; The transmission device adopts hard tooth surface reducer, elastic diaphragm coupling and DC motor to drive; It adopts hydraulic stop wheel and is equipped with slow drive device. The kiln head and kiln tail are respectively laminated with scales and sealed by cylinder compression, with good sealing effect.

5. Lime Rotary Kiln

◆ Product introduction: Lime rotary kiln is a kind of equipment widely used in the production of lime. It is also called drum rotary kiln. Its structure is more advanced. Both ends of the rotary kiln are sealed with combined scales to make the air leakage coefficient less than 10%. Composite refractory materials are used to reduce radiation heat loss. It is a rotating device that is usually used to heat limestone and other raw materials to high temperatures, causing them to decompose into compounds such as lime and carbon dioxide. This process is called lime calcination. In a lime rotary kiln, the raw materials are fed from one end of the kiln, through a high temperature zone inside the kiln barrel, and eventually lime and other products are produced at the other end.

◆Technical characteristics:

1. The vertical preheater with advanced structure and low pressure loss can effectively improve the preheating effect. The decomposition rate of limestone after preheating can reach 20-25%, and 10-15mm fine limestone can be directly used;

2. Reliable combined scale sealing at both ends of rotary kiln. Use composite refractories to make the air leakage coefficient less than 10% to reduce radiation heat loss;

3, filling type, partition ventilation round or square vertical cooler, so that the cooler lime temperature is 800C + ambient temperature, easy to transport, storage, and can be into the kiln secondary air preheating to 7000C above, reduce moving parts and special materials.

6. Rotary cooler

◆ Product introduction: Rotary cooler is used for compound fertilizer production to cool fertilizer with certain temperature particles. Rotary cooler and dryer can greatly improve cooling speed, reduce labor intensity, increase yield, further remove part of water and reduce the grain temperature of compound fertilizer.

◆ technical features: rotary cooling machine can also be used for other powder, granular material cooling the equipment compact structure, high cooling efficiency, reliable performance, strong adaptability.
