The Raymond mill is the grinding equipment to grind wet materials by the use of the grind effect between the grinder roll and grinder ring. It is mainly used for the fines processing work of verious of mineral materials, which Moh"s hardness is under 7 level, the water content is less 6%. Raymond grinder mill is suitable for the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 100 meshes to 325 meshes according to requirements.
The Raymond grinding mill"s work is that rely on the constant voltage click to drive the grinder roller rotate continuously, more than once extrusion grinder ring to make the materials grind slowly. But in the working process, the device"s motor voltage could instability because the device"s working load is oversize, and instability voltage could cause prodigiouss damage. They are mainly the following three points:
First, the high pressure Raymond grinder"s voltage instability will lead that the antiquity device"s wind pressure is sometimes small or big, resulting the chamber"s pressure is unstable. When the voltage become small, the chamber"s wind pressure also become small, then the grinded materials can"t easy to feed into the analyzer with the flowing air, this can result large quantities of the materials powder accumulate in the chamber, resulting the device"s air conduit is blocked, and affecting the finished products" output. When the current is oversize, blower"s wind power is oversize, resulting the materials that can"t grind fully are discharged with the airflow from the air flue, which affect seriously the finished products. Therefore, during using the device, user should adjust the Raymond grinder mill"s voltage to the constant state to ensure the device"s stability, security work.

Sand maker can also be called artificial sand maker, and at present it has replaced traditional sand making machines such as hammer crusher, roll crusher and rod mill and become the main equipment of the artificial sand making industry. This product is widely used in crushing various kinds of mine, cement, fire-proof materials, bauxite, corundum, glass raw materials, building sand, stone materials, and other metallurgical slag. It is especially efficient to crush harder materials, such as carborundum, corundum, and magnesium sand, better in capacity than of other crushers. Sand making machinery can be used for sand production line, sand and gravel aggregate production line, and led the Chinese green sand maker plant in the sand fields has made remarkable achievements .
Artificial sand trend has been unstoppable, and in this state of the market, one can produce an urgent need to sand material equipment. Sand It is in such cases, to fill this gap in the market. Henan Hongxing Mining Machinery Co., Ltd. professionally develops crushing and screening equipment with the advantages of high efficiency, energy saving, pollution-free characteristics, excellent technology, first-class service.
Here Hongxing Machinery will list some tips on maintenance of the sand making machinery.
1. Before operation and maintenance of equipment, operators should make sure that you have known wellabout the instruction manual and the safety operation rules.If there are any accident occurs, you know how to stop the machines.
2. The qualified parts and the right tools should be used when maintaining the equipments.
3. All the equipments and motors should be turned off during the process of maintenance.
4. Any abnormal phenomenon of the equipment should be reported to higher authorities
5. Don’t lubricate, clean, repair or maintain machine while it is working and operating.
6. Re-install all safety devices before machinery and equipment startup.
7. Use the recommended lubricants in the manual.
