PGC-S型單齒輥破碎機 Single-tooth  Rolling Crusher

單齒輥破碎機安裝在燒結機尾部，用來破碎經燒結后從燒結臺車上卸下來的熱燒結礦，是燒結廠整粒系統的主要設備。

Single-tooth rolling crushers  are installed at the end of the sintering machine to crush the hot sintered ore  unloaded from the sintering maching trolley after sintered. They are the main  equipment of size stabilization system in the ore-sintering plants.

我公司生產的單齒輥破碎機分別與燒結臺車寬度為1.5米、2.5米、3.5米和5米的幾種規(guī)格燒結機相配套。1980年后，引進了日本的先進技術，經幾代技術人員的努力，在單齒輥破碎機的設計和制造工藝上不斷改進，先已達到國際先進水平。經多年的運轉實踐證明：機器運轉可靠，使用壽命長。近幾年，工業(yè)自動化的發(fā)展迅速，我公司生產的單齒輥破碎機完全可適應燒結廠集中控制的工業(yè)程度。

The single roll crushers  produced by our company respectively match sintering machines of several specifications  with the widths of sintering maching trolley of 1.5m, 2.5m,  3.5m and 5m. In 1980, we introduced Japan ’s  advanced technology. After the effort made by several generations of  technicians, we continuously improve the design and manufacturing techniques of  single roll crushers. Now, they have reached the international advanced level.  Many years of operation practice demonstrate that the machines operate reliably  and enjoy long service life. In recent years, thanks to the rapid development  of industrial automation, the single roll crushers manufactured by our company  are able to adapt to industrial degree of sintering plants centralized control.

單齒輥破碎機由傳動裝置、齒輥（軸輥）裝置、輥軸給排水冷卻裝置、支撐臺車、篦板、密封罩、導槽等主要部分組成。由電動機通過安全聯軸器，經減速裝置帶動齒輥旋轉。篦板安裝在齒輥下方，當熱燒結礦從燒結機尾部卸下，通過導槽進入到篦板上面時，齒輥旋轉借助破碎齒的剪切和擠壓作用，將熱燒結礦破碎成所需要的粒度。因破碎物料溫度高，輥軸、輥齒、篦板均設計成通水冷卻式，并在表面堆焊耐磨耐熱的硬質合金，以提高使用壽命。破碎后的熱燒結礦塊從破碎機下溜槽進入冷卻機。小型單齒輥破碎機只有主軸通水冷卻，齒冠采用合金鋼鑄造，篦板上裝有護板可以更換。

Single roll crushers are mainly  composed of transmission device, tooth roll (axle roll) device, roll shaft water  supply and drainage cooling device, supporting trolley, grate plate, seal  cover, and guide slot. The motor drives the rotation of roll through reducing  device by virtue of safety coupling. The grate plate is installed below the  roll. When the hot sintered ores are unloaded from the end of the sintering  machine and get to the top of the grate plate through the guide slot, the  rotating roll crushes the hot sintered ores into the required particle sizes  through the shearing and squeezing action of the crushing teeth. Since the  temperature of the crushing materials is high, the roll shaft, roll teeth and  grate plate are all designed into connecting water cooling type. Repair welding  of wear-resisting and heat-resisting is conducted on their surface to prolong their  service life. The crushed hot sintered ores enter the cooling machine from the  chute below the crusher. In the small single roll crusher, only the main shaft  uses water to cool. The crown is cast through alloy steel. The grate plate is  equipped with guard board which can be replaced.

為檢修方便，齒輥本身也可以整體吊裝。大規(guī)格單齒輥破碎機的篦板安放在可以移動的臺車上，可整體拉出推入，以減少停車維修時間。

For the convenience of  examination and repair, the roll itself can be hoisted integrally. The grate  plate of large single roll crusher is placed in the movable trolley and can be  pulled out or pushed in integrally to reduce stopping and maintenance time.

單齒輥破碎機的安全聯軸器、低速聯軸器和大小齒輪等旋轉運動部件必須有安全防護罩等裝置，安全衛(wèi)生。單齒輥破碎機自帶防塵罩。大規(guī)格的破碎機帶大型防塵罩，并能與吸塵裝置相聯接，衛(wèi)生環(huán)保。吸塵裝置可由用戶自備。

Rotating parts such as safety  coupling, low-speed coupling, as well as big and small gears in the single roll  crusher must be equipped with devices such as safety shields. They are safe and  hygienic. The single roll crusher has dust cover of its own. Large crushers are  equipped with large dust covers and can connect with dust suction installations  which are safe and environmentally friendly. The dust suction installations can  be provided by the users themselves.
