第一章   概  述
Chapter 1 Summarize
辊压机是八十年代中期在国际上发展起来的新型粉碎设备。以它为主组成的挤压粉磨新工艺在节能方面有着显著的效果,受到国际水泥界的普遍重视,成为发展粉磨工艺的一项新技术。
Roller press is a new type of crushing equipment developed internationally in the mid-1980s. The new extrusion grinding technology mainly composed of it has a significant effect in energy saving, and it has been widely valued by the international cement industry and has become a new technology for the development of grinding technology.
该机应用高压料层粉碎能耗低的原理,采用单颗粒粉碎群体化低工作方式。脆性物料经过高压挤压(该机在压力区的压力约为150Mpa)使物料的粒度迅速减小,小于0.08mm的细粉含量达到20～30%,小于2mm的物料达到70%以上,并且在所有经挤压的物料中存在有大量的裂纹,使物料在下一个工序中粉磨时,所需的能耗大幅度降低。根据国外有关资料的报导和我们已取得的实际使用经验,采用此设备的粉磨系统比未采用该设备的粉磨系统可增产50～200%。单产电耗可降低20～35%。并且由于磨辊的磨损小,使得单位磨耗大为降低,同时设备工作的噪音、粉尘等均较小,改善了工人劳动环境,充分显示出其卓越的经济效益和社会效益。
The machine applies the principle of low energy consumption for high-pressure material crushing, and adopts single-particle crushing and grouping low working mode. Brittle materials undergo high-pressure extrusion (the pressure of the machine in the pressure zone is about 150Mpa) to rapidly reduce the particle size of the material. The content of fine powder less than 0.08mm reaches 20-30%, and the material less than 2mm reaches more than 70%. There are a large number of cracks in all extruded materials, which greatly reduces the energy consumption when the materials are ground in the next process. According to the reports of relevant foreign materials and the actual use experience we have obtained, the grinding system with this equipment can increase the output by 50-200% compared with the grinding system without this equipment. Power consumption per unit of production can be reduced by 20 to 35%. And because of the small wear of the grinding roller, the unit wear is greatly reduced. At the same time, the noise and dust of the equipment are relatively small, which improves the working environment of workers and fully demonstrates its excellent economic and social benefits.
辊压粉碎机的主体是两个相向转动的辊子。脆性物料由输送设备,送入装有称重传感器的称重仓,而后通过辊压机的进料装置,进入两大小相同,相对转动的辊子之间,由辊子一面将物料拉入辊隙中,一面以其间的高压将物料压成密实的物料饼,最后从辊隙中落下,经出料斗,由输送设备提出。由下一工序对物料饼作进一步的分散或粉磨。
The main body of the roller crusher is two rollers rotating towards each other. The brittle material is sent by the conveying equipment to the weighing bin equipped with the weighing sensor, and then passes through the feeding device of the roller press, and enters between two relatively rotating rollers of the same size, and the material is pulled into the roller gap by the roller side. On one side, the material is pressed into a compact material cake with the high pressure in between, and finally falls from the roll gap, passes through the discharge hopper, and is lifted by the conveying equipment. From the next process, the material cake is further dispersed or ground.
 
第二章  结构简介
Chapter 2 Structure introduction
辊压粉碎机结构较为复杂,载荷很大,系统、部件较多。为了更好地使用该设备,必须对其各个部件和系统必要的了解。
The structure of the roller crusher is complex, the load is large, and the system and components are many. In order to use the equipment better, it is necessary to understand the various components and systems.
该设备是由轴系、主机架,进料装置、传动系统、液压系统、润滑系统、辊罩、检测系统组成。见辊压机总图。
The equipment is composed of shaft system, main frame, feeding device, driving system, hydraulic system, lubrication system, roller cover, and detection system. See the general drawing of the roller press.
两磨辊分别为固定辊与活动辊,活动辊安装于机架内腔的导轨上,固定辊固装于机架立柱上。进料装置、液压系统、润滑系统均安装在主机架上。主减速机—行星减速机用缩套联轴器悬挂在主轴上,由扭矩平衡装置平衡其输出扭矩,主电机的驱动力矩通过十字轴式万向节传动轴传给行星减速机。
The two grinding rollers are respectively fixed roller and movable roller. The movable roller is installed on the guide rail in the inner cavity of the machine frame, and the fixed roller is fixedly installed on the column of the machine frame. The feeding device, hydraulic system and lubrication system are all installed on the main frame. The main reducer-planetary reducer is suspended on the main shaft with shrink sleeve coupling, and its output torque is balanced by torque balance device. The driving torque of the main motor is transmitted to the planetary reducer through the cross shaft universal joint drive shaft.
轴系分两套,其中一套是固定不动的,即固定辊轴系,另一套则是可以在机架内腔作水平方向往复移动的,即移动辊轴系。两磨辊间对物料形成的高压是由液压系统中的液压缸产生的,当无物料通过时,液压缸产生的力由移动辊轴承座经中间架传给固定辊轴承座。不管有无物料通过磨辊,挤压粉碎力均在机架上被平衡,基本不传到基础上。该设备中的液压缸与蓄能器组成一液压弹簧,保持一较恒定的挤压粉碎力,同时兼有安全保护功能。主电机采用交流异步电机,整机采用微机控制。
The shaft system is divided into two sets, one of which is fixed, that is, the fixed roller shaft system, and the other is capable of reciprocating horizontally in the inner cavity of the frame, that is, the moving roller shaft system. The high pressure on the material formed between the two grinding rollers is generated by the hydraulic cylinder in the hydraulic system. When no material passes through, the force generated by the hydraulic cylinder is transmitted from the moving roller bearing seat to the fixed roller bearing seat via the intermediate frame. Regardless of whether the material passes through the grinding roller, the squeezing and crushing force is balanced on the frame, and basically not transmitted to the foundation. The hydraulic cylinder and the accumulator in the equipment form the hydraulic spring, which maintains a relatively constant squeezing and crushing force, and also has a safety protection function. The main motor adopts AC asynchronous motor, and the whole machine adopts microcomputer control.
现将该设备中主要部件简介如下:
The main components of the equipment are introduced as follows:
一．主轴轴系
1. shaft system of main shaft
该部件由堆焊有一定厚度耐磨材料的磨辊主轴、双列球面滚子轴承,轴承座以及内、外轴承端盖、定位环、端面热电阻、水冷系统等零部件组成。见轴系装配示意图。
The component consists of grinding roller main shaft with a certain thickness of wear-resistant material, double-row spherical roller bearings, bearing seats, inner and outer bearing end covers, locating rings, end face thermal resistance, water cooling system and other parts. See the shaft system assembly drawing.
主轴采用分体式,由轴体和轴套两部分组成,轴套表面堆焊了一层耐磨层,在耐磨层磨损后可在其上直接进行补焊修复,若轴套使用到无法修复的程度,则可更换一新轴套。主轴两轴承支承处,均为圆锥段,使主轴承的拆卸可借助于超高压油泵进行,便于检修更换。
The main shaft adopts split type and consists of two parts: the shaft body and the shaft sleeve. The surface of the shaft sleeve is welded with a wear-resistant layer. After the wear-resistant layer is worn out, it can be directly repaired by welding. If the sleeve is used to the extent that it cannot be repaired, it can be replaced with a new sleeve. The two bearing supports of the main shaft are both tapered sections, so that the main bearing can be disassembled with the aid of an ultra-high pressure oil pump, which is convenient for maintenance and replacement.
主轴承采用具有自动调心功能的双列球面滚子轴承。该轴承具有承载能力大,寿命长的特点,并采用智能干油润滑,保证其具有良好的润滑条件。
The main bearing adopts the double row spherical roller bearing with self-aligning function. The bearing has the characteristics of large carrying capacity and long life, and uses intelligent dry oil lubrication to ensure good lubrication conditions.
端面热电阻是用以检测主轴承工作温度的,它紧贴在主轴承的外圈上,保证连续检测,报警,控制主轴承温度。
The end surface thermal resistance is used to detect the working temperature of the main bearing. It is closely attached to the outer ring of the main bearing to ensure continuous detection, alarm and control the main bearing temperature.
水冷系统是用来降低主轴及轴承的工作温度,从而使轴系能稳定地连续运行。
The water cooling system is used to reduce the working temperature of the main shaft and bearings, so that the shafting system can run stably and continuously.
二．主机架
2. main frame
主机架是整个挤压粉碎机的基础, 挤压粉碎力由其承受。为便于减轻重量全部采用焊接结构,由上、下横梁、左、右立柱、承载销、定位销、导轨及联接螺栓组等组成。见主机架装配示意图。上、下横梁、左、右立柱均在焊接后作了整体退火处理,以消除其焊接应力。
The main frame is the foundation of the entire extrusion crusher, and the crushing force is borne by it. In order to reduce the weight, all welded structures are adopted, which are composed of upper and lower beams, left and right columns, bearing pins, positioning pins, guide rails and connecting bolt groups. See the main frame assembly drawing. The upper and lower beams, the left and right columns are all annealed after welding to eliminate the welding stress.
上、下横梁采用工字型结构,具有较大的刚度, 左、右立柱采用工字型与箱型结构相结合的结构,同样具有较高的刚度,使整个机架可连接成为一个刚性的整体。
The upper and lower beams adopt I-shaped structure, which has greater rigidity. The left and right columns adopt the structure that combines I-shaped and box-shaped structures, which also have high rigidity, so that the entire frame can be connected to become a rigid overall.
承载销主要起到将立柱上所受的粉碎力传递到上、下横梁上去的作用。在安装时应注意其标记。
The load-bearing pin mainly plays the role of transmitting the crushing force on the column to the upper and lower beams. Pay attention to its markings during installation.
定位销的主要作用是用于确定两侧上、下横梁的中心距。
The main function of the positioning pin is to determine the center distance of the upper and lower beams on both sides.
导轨是作为活动辊轴承座的导向装置而设置的,两侧的轨宽度有所不同,靠近传动侧的导轨应宽些。
The guide rail is set as the guide device of the movable roller bearing seat. The width of the rail on both sides is different, and the guide rail near the driving side should be wider.
螺栓组是确保机架联接的关键所在。因此该高强度螺栓不可用普通螺栓代用,并且在拧紧时应控制拧紧力矩。
The bolt group is the key to ensure the frame connection. Therefore, the high-strength bolts cannot be substituted with ordinary bolts, and the tightening torque should be controlled when tightening.
