A quarry is a place from which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate has been excavated from the ground. A quarry is the same thing as anopen-pit mine from which minerals are extracted. The only trivial difference between the two is that open-pit mines that produce building materials and dimension stone are commonly referred to as quarries. But do you know the major problems of quarry machines in CHINA?
1. A serious shortage of investment, illegal operation: Quarry equipment owner to reduce the mining cost, not to make the necessary input, extensive use of artificial engaged in the exploitation of more primitive, process and equipment.All quarries are not in accordance with the provisions of the "three simultaneity" construction production safety, regardless of their stage of top-down mining, violation of operating procedures to use desktop drill lateral drilling or from down to up,Blaster violations, explosion cut hole blasting or fry the umbrella eaves;Individual owners in a slope of rock at the bottom of the tao, the huge umbrella eaves and rock plate hanging in the sky, hundreds of cubic meters, for the following workers "taishan coping" streak, after the rain and more sunny weather easily to collapse and slide, the similar accident occurred in a row.
2. The investment scale of quarry machine not limit: More than one certificate mining or a mining face card more abundant small quarry mining. Small quarry owners tend to invest in ten yuan, employ more than 10 people around two mining processing mill, mining scale and specification cannot be achieved;The boundaries of the quarry is due to the dynamic control and mutual interference, cause difficult to dispute, neighbors mining out of sync, form the safe hidden trouble.
3. Lack of effective supervision and management for mining: According to the current production safety laws, regulations and department rules and regulations, safety in production law enforcement main body for the government and relevant departments at or above the county level, township government can only work in the general inspection, not the quarry and other township enterprises for safe production law enforcement investigation.

A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object. Cement rotary kiln equipment as an important equipment in metallurgy and chemical industry, the equipment is expensive. The appropriate rotary kiln equipment not only should not only with reliable quality, easy to operate, advanced technology, but also can guarantee improve the production efficiency in production. As customers, when you choose the suitable equipment, you can consider from process, technology, the later operation and other aspects of rotary cement kiln. And the following is the detailed considerations to purchase rotary kiln equipment.
1. According to the actual need
When purchase cement rotary kiln equipment, the first you should clear know your actual need. Then according to your required yield and investment to decide the size of rotary kiln, and know the relevant performance of equipment to guarantee to choose the suitable equipment in various of rotary kiln equipments.
2. The stability of the cement kiln
In the process of production must guarantee the enough stability of the equipment to avoid the damage of equipment parts, thus bring unnecessary maintenance cost to users and resulting in the higher cost.
3. Accessories should conform to the national standard
Part of the horizontal kiln equipment accessories is by purchasing or produced by itself. In face of so mnay manufacturers, when choosing rotary kiln equipment should strict according to the equipment configuration, especially should pay attention to the quality and performance of clinker rotary kiln.
4. The precision of the rotary cement kiln
The precision of equipment is an important factor for purchasing rotary kiln, and this only can test in the production process, so the manufacturer must strict according to design drawing of rotary kiln to manufacture. Only in this way, we can fully guarantee the quality of rotary kiln equipment.

Magnetic separator is suitable for the wet magnetic separation of the materials whose granularity is below 3mm such as magnetite, pyrrhotite, calcined ore and ilmenite and can also be used for removing iron from the materials such as coal, non-metal ore and building material. The magnetic system of China magnetic separator is a compound of fine ferrite material and rare earth magnets and the average magnetic induction intensity of the surface of the cylinder is 100~600mT.
China Magnetic separator is one of the machines with the widest application and highest universality in the mining industry and it is suitable for removing the iron to recycle the powder particles. Magnetic separator is widely used for the resources recycling in lumbering, mining, ceramics, chemistry and food industry. But do you know why the china magnetic separator may be blocked? Wet magnetic separator drain mouth blow pipe blockage due to impurities, cause jams tube mouth ore deposit or work, if you find must stop maintenance. Sometimes blow pipe mouth is not blocked but somewhere have stuff to make it work because of work space jams, drum skin without concentrate failure phenomenon is here.Solution: you can pressure hose from the feed water flushing, the blockage hedge.
China Magnetic separation machine commonly used with dry magnetic separator and wet magnetic separator, also divided into strong magnetic and weak magnetic separator, according to different needs of different mineral magnetic choose corresponding magnetic separator, ensures our dressing in the process of high grade and high efficiency.Is very widely the application of magnetic separation equipment, in all kinds of iron ore, tungsten ore, manganese ore, rare earths magnetic separator can be used to mine, at the same time, also can be used in building materials, such as coal and nonmetal iron, etc.
