milling machines except the spindle top sliding bearings of the exterior, the remaining drive for rolling bearings, and therefore must run well lubricated, can damage the bearings and shorten the service life.

Maintenance method following: spindle refueling time each class a times, but must note, found oil Cup within of oil no loss or loss too slow Shi, should immediately cleaning oil road, again plus mechanical oil, oil Cup location in spindle top, spindle base bearing, and mill roll bearing each class with butter gun raises lithium base grease once, Analyzer bearing each six months apart cleaning once, plus footlithium base grease, wind machine bearing room plus lithium base grease.

scm ultrafine mill is strictly prohibited within the metal block press, otherwise it will damage the grinding roller and grinding ring, Center hanger and so on.
feeding should be uniform, not less. Overcharge duct will be blocked, and lower production, easy to burn out the motor and charging too little will to feed production. Feeding granularity: hard plastic at the time of less than 15 mm in diameter, soft material is 20 mm in diameter, non-bulk material added to the machine.
fineness adjustment according to size, hardness and water content of the material, the proportion is different, different thickness of processing, can adjust the top of the Analyzer, high speed, high fineness and low speed, low fineness. Improve the fineness, yield will be reduced accordingly, if it does not meet the requirements should be debugged when fan speed, users can be flexible.

air flow adjustment: located in the fan air flow control valve on the inlet pipe, generally up to the maximum position, according to the required fineness, output adjustments. Located on the exhaust pipe of the exhaust gas outlet valve and transferred to inlet dust ejected then. Small volume, high fineness. It should be noted, air volume is too small, the precipitation within the ducts below the host item, use the appropriate adjustments.
grinding roll and ring of scrapping the limit, the remaining minimum wall thickness shall not be less than 10MM.

Mill Green design Green design concept

exist in most mtm trapezium grinder producing enterprises only pay attention to product quality, production costs and economic benefits, while ignoring the process of use, bring pollution to the surrounding environment. How to break through green trade barrier, green design, green manufacturing, green deal with the more severe challenges? the current consensus in many countries: economic development and environmental protection are equally important, indispensable one, have been adopted for sustainable development and strategic planning, has been continuously strengthened environmental protection and development toward the standardization and legalization.

green design is a kind of advanced design concepts in recent years. It refers to a product's entire lifecycle, to environmental protection and resource conservation as its core, especially considering the environmental attributes of products, such as: resource use, environmental impacts, disassembly, recyclability, and reusable, and so on.

green design, is the mtw milling machine green product key link. In design, to take full account of the mill's own negative effects on ecological environment and production technology, to damage control to minimize or even eliminate it. So, if towards the new concept of mill green design?

first production raw material mill must be recyclable, easy to break down, recycling, pollution-free. The current mill raw materials are steel, cast iron, alloys, can be recycled. If these materials can not meet the conditions of production, then, you must choose something non-toxic materials in place. Secondly, the mill will have a greater impact and vibration during the operation. In order to reduce the power loss and should be used with vibration absorption properties of high strength cast iron structure, stresses self bearing beams can be used and let in-house offset stress in the structure, while the use of vibration isolation performance of a variety of flexible supports. Green maintenance and repairs are needed. Reduction in consumption means reducing pollution and saving of resources, with minimal resource consumption, maintain or restore the function of the equipment, material and energy use efficiency, thereby enhancing the quality and efficiency of economic operation. Of course, dedusting and noise is the embodiment of green design, used in exhaust air cleaning, sealing, vibration and sound-absorbing function of structure is a good choice.

technology milling machines are adhering to the idea of green design. A case study of vertical mill, feed grinding principle, electricity consumption for ball mill 70%~80% only; full-sealed system, operation under negative pressure and dust-free; grinding rollers and grinding disc without direct contact, less noise, less wear, and low energy consumption. And as medium-speed grinder, using high performance pulse type dust collector, complete set of equipment operation, no dust pollution, and equipped with silencers and silencers, reducing noise pollution, the surroundings play a good role in environmental protection.
