Bucket elevator The machine has the advantages of big conveying capacity, high hoisting height, stable and reliable running and long working life. Its performance and parameter accord with JB3926?85 'Vertical Bucket Elevator', which consults the international standard and advanced foreign standard and the towing circle chain accords with MT36?80 'High-Strength Circle Chain for Mine'. The machine is applicable for conveying the power, grain and block materials, such as coal, cement, block, sand, clay and ore. The bucket elevator is allowed to convey materials with high temperature with the special circle chain structure.

联系人：刘永刚该类提升设备具有输送量大，提升高度高，运行平稳可靠，寿命长显著优点，其主要性能及参数符合JB3926----85《垂直斗式提升机》（该标准等效参照了国际标准和国外先进标准），牵引圆环链符合MT36----80《矿用高强度圆环链》，本提升机适于输送粉状，粒状及小块状的无磨琢性及磨琢性小的物料，如：煤、水泥、石块、砂、粘土、矿石等，由于提升机的牵引机构是环行链条，因此允许输送温度较高的材料。

Prominence a wide variety of shapes and movement characteristics, in general can be divided into four categories:(1) quiet prominence, change is slow, longer life expectancy, up to the number, and with the presence of sunspots related to sunspots for a long time, it is also a little more;(2) the activities of prominence, from a quiet prominence changes years, the movement is faster, but lower than the sun's surface escape velocity, so mostly circular, the material eventually thrown off the plane back to Japan;(3) the outbreak of prominence, activities of the most intense one, and sometimes velocity can exceed the Sun the surface escape velocity, reaching 100 km D seconds, or even higher altitudes of up to one million kilometers, 20,000 kilometers thick;(4) crown-shaped prominence, looks like clouds, is a rather exceptional prominence.

日珥有各种各样的形状和运动特征，大体上可分为四类：（1）宁静日珥，变化缓慢，寿命较长，可达数目，并与黑子的存在有关，黑子多时，它也多一些；（2）活动日珥，由宁静日珥变化而来，运动速度较快，但低于太阳表面逃逸速度，因此多为环形，抛出的物质最终仍落回日面；（3）爆发日珥，活动最激烈的一种，有时运动速度可超过太阳表面逃逸速度，达100公里D秒，甚至更高，高度可达上百万公里，厚达2万公里；（4）冕形日珥，貌似浮云，是一种比较特殊的日珥。
