輥壓機

 

      輥壓機是本公司承接的新型水泥節(jié)能粉磨設備，能全部或部分替代能耗高的球磨機系統(tǒng)，并且具 有耗材少、噪音低的功能，適用于新廠建設，也可用于老廠技術改造。選用該設備后，可使球磨機系統(tǒng)產量提高40—100%，經過擠壓后的物料料餅中0.08mm細料占20-55%,小于2mm占65-85%，小顆粒的內 部結構因受擠壓而充滿許多微小裂紋，易磨性大為改善。輥面采用熱堆焊，耐磨層維修更為方便。
       本公司多年來不斷追求改進、創(chuàng)新，已形成了一套成熟的設備技術和完整的粉磨工藝，主要特點：
1、輯面堆焊采用進口焊機和先進的耐磨焊條及工藝技術進行焊接，使用壽命大幅度提高。
2、利用航空技術生產的液壓油缸性能可靠。
3、自控系統(tǒng)采用觸摸屏動態(tài)顯示。自動控制配有專家診斷系統(tǒng)，故障自動解除，控制可靠。
4、配套打散分級機，V型分級機和回轉式打散分級機。分選率達90%。

        The roll squeezer is a new type energy-saving cement powder mill firstly manufactured by our company. It can completely or partially replace the ball mill with high energy consumption. It is featured by few consumables and low noise. It can be used for new factory construction and for old factory technical reconstruction. This equipment can help the ball mill system improve the output by 40—100%.
The squeezed material pie has 20~55% tiny particles of 0.08mm and 65—85% particles smaller than 2mm. The small particles are full of tiny cracks for being squeezed, so the grindability is greatly improved.
The roll surface is welded in the hot build-up way so that the maintenance of the wear-resistant layer is more convenient.
        Our company has been pursuing reform and innovation for years, and has formed a set of mature technologies and complete grinding techniques. The main characteristics are as follows:
1. The build-up welding on the roll surface is done by the imported welder and with the internationally advanced wear-resistant welding rods and techniques. The service life increases greatly.
2.The hydraulic cylinder produced by using aeronautical technology has a reliable performance.
3.The automatic control system has a touch screen. It has a professional diagnosis system so that the trouble can be removed automatically. The control is reliable.

工作原理
      輥壓機是根據(jù)料床粉磨原理設計而成，其主要特征是：高壓、滿速、滿料、料床粉碎。輥壓機由兩個相向同步轉動的擠壓輥組成，一個為固定輥，一個為活動輥。
物料從兩輥上方給入，被擠壓輥連續(xù)帶入輥間，受到100-150MPa的高壓作用后，變成密實的料餅從機下排出。排出的料餅，除含有一定比例的細粒成品外。在非成品顆粒的內部，產生大量裂紋，改善了物料的易磨性，且在進一步粉碎過程中，可較大地降低粉磨能耗。
      物料通過磨輥主要分為三個階段：滿料密集、層壓粉碎、結團排料階段。
 
主要結構
       輥壓機由機架、兩個輥系、傳動裝置、扭矩支承、輥罩、進料裝置、液壓（加壓）系統(tǒng)、主軸承潤滑系統(tǒng)、干油潤滑系統(tǒng)、電氣系統(tǒng)等部份組成。
