“正泰机械”研制生产的双级无筛底粉碎机,经过十多年来破碎细碎行业的应用实践,随着系列化生产和技术水平的不断提高,越来越显出无可比拟的优越性。
该机用于火电厂燃料间,可替代鄂破、环锤破、细破等一系列设备,投资少,占用空间小,操作人员减少,经济高效运行,节能降耗效果十分显著。用于矿山、水泥厂等原料入磨机前的细碎,真正体现了“多碎少磨” 的基本原则,充分发挥了细碎作用来提高磨机的处理能力,降低了磨机电耗和钢球消耗,磨机产量成倍提高。用于煤矸石、页岩生产新型墙体材料的制砖企业,解决了含水率高原料粉碎困扰砖厂正常生产的难题,颗粒级配合理,尤其适合生产多孔砖、薄壁砖。

该机相当于两台锤破合二为一,合理的组合成一个整体,两套转子串连使用,没有筛网蓖底,具有以下特点:
一、双转子上下两级粉碎
互相串连的两套转子,使经上级转子锤头击碎的物料立即被飞速旋转的下级转子的锤头再次细碎,内腔物料反向相互飞速碰撞,相互粉碎,达到锤粉料、料粉料的效果,直接卸出。
二、没有筛网篦底,高温物料,绝不堵塞
传统的带有篦筛板的粉碎机,不适应含水率高于8%的原料,当原料含水率高于10%时,极易发生严重堵塞,使锤头不能转动,物料不能排出,甚至烧坏电机,严重影响生产。
该机设计没有筛网篦底,对物料含水率没有严格要求,完全不存在糊堵筛板的问题,更不存在细粉不能及时排出,重复粉碎的问题,故粉碎效率高,存在锤头无效磨损现象。
三、独特的双向调隙技术
锤头磨损后与衬板之间间隙变大粒度变粗,可由中心往外移动锤头位置缩小与衬板之间的间隙继续使用。还可以由外向内推移衬板调节间隙,控制出料粒度。
四、装置配重平衡轮,运转平衡惯性大,节电20%
上下两套转子轴端均配有飞轮,飞轮可调节运转的周期性速度波动,使之运转均匀平稳,增加转动惯性,克服运动阻力,节电20%以上。
五、集中润滑系统,不停机注油、方便快捷
双级粉碎机润滑系统,一改黄油咀、油杯的传统加注润滑油方式;配置集中给油分配泵,一步操作,多路供油;整机可在工作状态下随时将所有轴承同时同步加注润滑油,方便快捷。由于全油路封闭,又可防止粉尘侵入损坏轴承。
六、液压启动机壳
液压启闭装置,只需要一人即可轻松启闭机壳,不仅轻巧快捷且安全可靠,便于维修。

Through decades of application and practice in crushing industry, as well as the improvement of serialization manufacture and technical level, the two-stage crusher designed by "Zhengtai Machinery" presents incomparable superiority .
Utilized in fuel workshop of thermal power plant, the machine can replaces jaw breaker, ring-hammer crusher and fine grinder etc., it features low investment, small occupied space, few operating personnel, economic and effective operation, its effects of energy conservation and consumption reduction are notable.
It is used in the fine crushing before the raw materials entering into the grinder in mines and cement plants, the basic principle of "more crushing, less grinding "is reflected, function of fine crushing is brought into fully playing to enhance the processing capacity of grinders, electricity consumption and steel ball consumption are reduced, volume of production of grinders is greatly increased.
Used in the brick making enterprises that are using coal gangue and shale to produce new type wall materials, the problems of raw materials with high moisture troubling normal production of brickyard is solved, the particle grading is reasonable, particularly suitable for production of perforated brick and thin brick.
The crusher is equivalent to two sets of hammer crusher and combined into a whole one reasonably, cascaded using of two sets of rotors without screen, has the ollowing characteristics:
I.Dual Rotor Crushing in Up and Down Two-stage
Two sets of cascade rotors make the materials crushed by up stage rotor hammer be fine crushed by the rotary down rotor hammer, materials in the inner space ollide with each other reversely and smash one another, the effect of hammer crushes materials and materials crush materials is achieved, and they can be unloaded directly.
II.No Screen, No Blocking for Materials with High Moisture Content
The traditional crushers with grate sieve plate can not meet the raw materials with the moisture content higher than 8%, serious blocking will occur if the moisture content of raw materials is higher than 10%, and the hammer can not rotate and materials can not be discharged, even the motor will be burned out and effect the production.
The design of the crusher is without screen, it has no strict requirements on moisture content of raw materials, the problem of blocking on the sieve plate is absent, and troubles that fine powers can not be discharged in time and repeated grinding do not exist either, so the grinding efficiency is high, and invalid abrasion of hammer does not exist.
III.Unique Bidirectional Gap Adjustment Technology
Granularity will coarsen and the gap between abraded hammer and liner plate largens after the hammer consuming, it is proper to move the position of hammer from the center to the outside to reduce the gap with liner plate and to continue to use. It is also allowable to push the liner plate outside-in to regulate the gap and control the granularity of discharged materials.
IV.Equipped with Balance Wheel Giving Steady Rotation and High Inertia, Saving Electricity for 20%
Ends of two sets of rotor spindle up and down are equipped with flywheels, which can regulate the periodical speed fluctuation of operation, and make operation uniform and steady, increase rotational inertia and overcome resistance to motion, it can save the electricity for more than 20%.
V.Centralized Lubrication System, Oiling without Machine Halt, Conveniently and Efficiently
Lubrication system of two-stage crusher changes the traditional lubricating oil injection method of grease mouth and grease cup; the centralized oil feeding equipped proportioning pump has one step of operation and can supply oil for multi-way; the complete machine can injects lubricating oil synchronously to all bearings under working position, which is convenient and efficient, it can also prevent intrusion of dust damaging the bearings.
VI.Hydraulic Pressure Starting Case
Hydraulic pressure starting and stopping equipment needs one person to start and stop the case easily, it is not only light and handy,but also safe, reliable, and convenient for repairing.
