Which Types Of Stone Crusher And Milling Equipment Are Mainly Used In Quarry Sites?

PR Log (Press Release) – Dec 29, 2009 – Generally speaking,we classify 2 kinds of crushers by the effects of the crushing force: 1 Stone crusher. 2 Grinding mill. For a stone crusher, which is always used for processing bigger stuff, the final product is coarse, above 8mm usually. The main feature is that there is a little space  between crushing parts, crushing parts are no touching each other. Stone crusher can be classified coarse crusher, medium crusher, and fine crusher. For Grinding mill, the material is always much finer, final product is fine powder, the fitness can reach up to 0.074mm or more, The main feature of a grinding mill is crushing parts or medium touches each other, The medium is steel balls, steel bars, mineral or stone pieces. There are some crushers doing crushing and grinding jobs both, for instance, autogenous tumbling mill.
According to the crushing style & mechanical structure, six categories of crusher is classified :
1 Jaw crusher  The principle is to use a fixed jaw and a swing jaw to crush the material into small pieces.
2 Cone crusher  Material is crushed in the space between two roller cones one is fixed, the other is eccentrically moving, the roller cones take action with each other to crush the material.
3 Roller crusher  Material is continuously crushed between the two rollers running the same direction, with grinding and polishing forces, too, what’s more, the teeth shaped roller surface reinforces the crushing.
4 Impact crusher  Material is crushed by the impact force from high speed rolling rotor and plate.
Hammer crusher ,Cage crusher, strike crusher included in this type.
5 Grinding mill  Stuff is grinding by rollers (or steel balls, steel bars, stone or mineral pieces) in a rolling cylinder.
6 Other Grinding mill types:
A  Roller mill  Rolling rollers grind stuff to fine powder.
B  Disk grinder  The grinding parts is vertical or horizontal rolling disks.
C  Centrifugal pulverizer  To grinding material with eccentricity produced high speed rolling parts and medium.
D  Vibrating grinding mill  High-frequency vibration makes medium and material crushed with each other.
Various kinds of crushers have different specification and uses. At present, for coarse crushing jaw crusher and impact crusher cone crusher is widely used, medium crushing, jaw crusher impact crusher and cone crusher is suitable, while fine milling, grinding mill or pulverizer is needed.

Maintenance of Spring Cone Crusher

PR Log (Press Release) – Dec 29, 2009 – Usage and Maintenance of Cone Crusher
Cone crusher is suitable to crush various kinds of ores and rocks of medium or above medium hardness,and cone crusher is of stable structure, high efficiency, easy adjustment, and use economically, etc. The spring safety system of crusher acts as an overloading protection system that allows metals to pass through the crushing chamber so as not to damage the cone crusher.The safety system uses dry oil and water as two kinds of sealed formation to make plaster powder and engine oil separated to make surereliable performance. The type of crushing chamber depends upon the size of feeding and fineness of the crushed product. The standard type(PYB) is applied to medium crushing, the medium type is applied to medium or fine crushing and the short head type is applied to fine crushing. According to stave work need of Cone crusher, cone crusher is maily usely in the compressive strength not surpassing 300Mpa each kind of ore and rock to medium crush and in broken bits .this is a typical equipment of our country for crushing hard ore to medium crush and broken bits.it is widely applied.it has the charateristics of high reduction ratio, high output,,few powder lost, , the product granularity even, strong compatibility of hard grain.
Cone Crusher Protection
Hydraulic Cylinders (typically actuated by noble gasses like nitrogen vs hydraulic oil) can collapse the springs and allow uncrushable material to exit the cone. This can be automatically actuated should the cone stop motion during operation. cone crusher Beveled GearsThis gear set translates the horizontal rotary motion of the counter shaft into the vertical rotary motion of the main shaft. They are typically forged and cut for strength and low noise. Top Cell LinersMaterial to be crushed enters the cone chamber through something called the top cell, which is typically lined with manganese liners. A device called a rotary feed distributor is sometimes added to the top cell to distribute the input material evenly throughout the bowl. When feeding a cone from a screen the rock obviously is always entering the crushing chamber on one side of the bowl only, the rotary feed distributor slings the materials around both side of the cone head, filling the crushing chamber more evenly resulting in potentially a better wear pattern and even better gradation from the full choke fed feed chamber.
Important Considerations for Cone Crushers
Cone Crusher Mantle Diameter cone crusher come in different sizes depending on desired production output rates. This size also determines the maximum diameter of input material the cone crusher can handle. Fine vs Standard Head Size This has to do with the clearance built into the mantle in terms of its distance from the liners. Fine heads have less clearance and can produce a finer output product while standard heads allow for a larger output product. Remote Adjustment in Cone Crushers Remote adjusters in cone crushers are a quite valuable feature, often adding $100,000 to $150,000 to the price of a unit. They allow for "on-the-fly" adjustment of the mantle/liner clearance distance. If you don't have this feature you must stop the crusher and adjust it with wrenches. Some manufacturers included this as a standard feature.

A Restaurant Software Can Do Wonders for Your Business

PR Log (Press Release) – Dec 21, 2009 – For a business to be successful, there are many factors that need to be though of when considering restaurant software. Although this is the case, restaurant owners should know that it is the best way to have everything under control. Purchasing the right POS will take a business to the next level and have complete control over operations, increasing effectiveness, increasing profits and will allow an owner to fine-tune his business strategies. However, if the wrong system is chosen, it will be a waste of time and money; and could even cause more frustrations. The owner may think of the POS system as a glorified cash register because even the most basic POS consists of a computer, cash drawer, receipt printer, and an input device. In addition to being a cash register, pos software can also create a detailed report which can aid the business owner in making informed decisions. Having this system will save a business owner a lot of money, improve his profits, and lessen the amount of time spent on making business plans.
Restaurant software will not only save more money, but help the owner, in terms of having more control over his business. There are other ways that a POS can help a business become more successful.  First, a computerized POS will reduce the shrinkage caused by theft, waste and misuse by staff members, since they will know that inventory is being tracked. This is a sure way to keep internal shrinkage to a minimum. Second, whether barcode scanning is used or not, the POS makes sure that every item in the store or on the menu is sold at the correct price.  The staff will no longer have to guess the price of an item and if prices need to be changed; it can be simply be done. Third, the owner may easily find out which items were sold during a business day, be it yesterday, the week before or even a month ago; with the help of a POS system. In addition, it will tell you how much money is in the drawer, as well as how much of it is profit.
Other benefits include a reduction in paperwork and the time spent doing inventory, sales figures, and other repetitive paperwork. All these tasks may be done in a smoother manner, thanks to the innovation of the restaurant software.  The key focus of restaurants is efficiency and the only way for this to be attained is by acquiring the help of a POS system. It will help the owner be able to get in control of his business and have everything at close view, which means he will easily manage the inventory and other important reports. There is no doubt that having this type of system implemented will save money, time, and effort.
