650式对辊式压密机

摘要

压密机是用于粉料成球的设备，目前主要用于冶金白灰筛下料，氧化铁皮以及各种物料的制球生产，本压球机是在原高压压球机基础上进行改进设计的，这次改进设计中能使压球机能够进行干压压球，设计中增大了予压机的挤压力矩同时也加大了供料量,并对油压系统做了重新设计，由于双传动占地面积大，这次改为单传方式，使压球机更加紧凑 
由于成型物料的种类不同，它所要求的压缩比相差很大为适应这一要求，予压电机采用滑差调速电机通过对予压螺旋转速的改变，实现改变加料量的目的，调速方式采用手控的，通过试验机的工业试验证明，成型单位压力与供料量有密切的关系，而与总压力的无明显的直接关系，所以不必用总压力的变化作调速的依据，可观察主电机工作电流的变化量作为调速的依据，主电机通过皮带轮得到两种速度，如须增加供料量可以取下螺旋衬套换上直径大的螺旋即可。

650 Pressure ball machine is used for powder into a ball of equipment, which are mainly used in metallurgical lime sieve of material, iron oxide and of all kinds of material in the ball production, the ball is in the original machine pressure phi  high pressure ball machine based on improving the design, the design improvement can pressure on dry pressing machine can ball pressure ball, design increases the pressure of extrusion machine to torque and increase the feed for, and the hydraulic system to do the design, because the double transmission covers an area of big, the way to request, makes the ball machine more compact
Due to the different kinds of material molding, it required is great for adapting to the compression ratio this request, to pressure the motor control motor sliding through the pressure of the spiral speed to change, realize the purpose of the feed and change, the speed adjustment way by hand control, through the test enginery industrial experiments prove, forming units pressure and for shoes have close relations, and total pressure and has no obvious direct relation So don't have to use the total pressure of the variation of the speed, the basis of the main motor can observe the variation of working current speed as the basis, the main motor through two speed by pulley, such as must increase feed can take for spiral bushing change into large diameter spiral can.
