Technological Analysis

Roll crusher, appeared in 1806, is the most ancient crusher (jaw crusher), which is invented by English as man thomas. Its roots can go back to the ancient treadmill, which is the prototype of roll crusher. The working principle of treadmill is also the working principle of roll crusher. The treadmill continues to improve current in production process, evolving to several types, such as the plain-roll crusher, which is used in the metal mine industry; the rod-toothed crusher, which is used in the coal industry and so on. However, the development of traditional roll crusher is limited, making slow progress. In the 1980s, based on research result of professor shaw in university krauss, krupp company and khd company in german launched the high-pressure roll crusher. The high-pressure roll crusher adopts the high-pressure crushing force, which devastated the material in the contact.

The impact in the roller reduces the relative sliding action between the material and the roll surface. The high-pressure force from roll to the material surface improves the working efficiency of crusher and reduces the wear rate of roll surface, making the high pressure grinding roller move towards the industrialization. The machinery manufacturing methods of Hongxing roll crusher and rod-teethed crusher has always been a mystery in machinery manufacturing industry. Hongxing roll crusher has been awarded three national patents. Now, let Hongxing experts share their technology with us patent. Gunnar Peterson has much experience in this field. Unique roll crusher structure First of all, driving system works like this: two motors drive rollers through triangle belt transmission. The two rolls force the ore particles between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.

Secondly, the coexistence out of the equipment can be adjusted. The particles are drawn into the gap between the rolls by their rotating motion, to wedge block formed between the rolls and the particle, called adjusting device. Adjustment bolts are fixed on the top of the wedge block. When bolts pull wedge block up, the wedge block push moving away from fixed roll roll, the gap become bigger, and the discharging coexistence become bigger. And vice versa. Double roll crusher have teeth on the face of the roll, and it is designed with high capacity. The connecting method about motor and speed reducer adopts hydraulic coupler. The equipment is mounted with overloading protective device to ensure operation. The gap width between the rolls can be changed by hydraulic adjustment system. Centralized lubrication system, which can lubricate all parts. Tooth design optimized. With economic growing a variety of metals and non-metallic minerals, cement factories, buildings, gravel and metallurgical industry have expanded their production scale; crushers their processing machines play a very important role in the development, and have become stanchion of the industry. It is expected that efficient free-pollution fuel and machinery will have good development prospects in the future. To a certain extent, reducing power consumption or improving system output can solve the problems of low production and disorder operation in cement enterprises. Roll crusher continually accelerate its development, adopt a simple, practical and versatile mechanical electrical protection system for hydraulic crushing materials of medium hardness in cement, metallurgy, chemicals, electricity, coal and other industry sectors, for example, it is used in coarse crushing or fine crushing limestone, slag, coke, coal and other materials.

Questions About The Plan Of Development Of Neiva I

Usually when a mayor or any elected official, begins to govern, his clock starts a countdown that appears to have a measure of time shorter than the other humans. Days pass with surprising speed, the months are when finished just they were starting and large projects seem to enter a kind of Chamber of extreme slowness that overwhelm the ruler to the point of despair. The team of collaborators never returns to worry what the head of the Administration suggested when he was candidate and the Development Plan which is the document where these points are precisely appropriated as a legal norm becomes a formality to which reference should be made obligatory, making a maximum effort so that actionsworks and accomplishments of the official fit so be the force within that straitjacket. Nobody seems to be interested in making detailed monitoring Plan indicators nor much less to factor proportional achievement of the targets in the times established. Therefore, and without the mood to upset the Mayor of our city, I refer to some Plan of development goals whose fulfilment only local administration can give reason.
