Material conveying device and cement clinker production system

Abstract

The invention relates to a material conveying device and a cement clinker production system. The material conveying device comprises a first feeding chute, a second feeding chute, a first flow dividervalve connected with the first feeding chute, a second flow divider valve connected with the second feeding chute, a four-way valve with four connecting ends and gate valves arranged on the connecting ends of the four-way valve and used for controlling opening and closing of the connecting ends. The cement clinker production system comprises the material conveying device, two roller presses and two mills. The two roller presses are connected with the first flow divider valve and the second flow divider valve correspondingly. The two mills are connected with the first feeding chute and the second feeding chute correspondingly. The material conveying device and the cement clinker production system are used for producing cement clinker. During production, a main material and an auxiliary material are crushed through the different roller presses and then are milled. The production energy consumption and equipment loss are further reduced. The product quality is further improved.

Problems solved by technology

[0002] With the continuous improvement of domestic environmental protection requirements, production suspension and rectification, and the impact of market demand, the shipment volume of some cement production plants has dropped significantly, resulting in the inability of production equipment to operate at full capacity, single-mill production cannot meet the required output, and double-roller double-mill production It will cause frequent start-up and shutdown

The frequent start and stop of production equipment will bring high electricity costs, and the damage to the equipment will be greater, and the hidden maintenance costs will increase. If cement production continues in the traditional way, it will inevitably lead to reduced machine hours, increased power consumption, and excessive loss of equipment, etc. question

[0003] In addition, the market's requirements for cement quality are also constantly improving. The original production method is to mix clinker and auxiliary materials together and then grind them. Since the particle sizes of the main and auxiliary materials are different, the particle size of the main and auxiliary materials is different during the grinding process. The distribution of the clinker is not uniform, and the performance of the clinker cannot be fully exerted.
