Rotating drying kiln is thermal processing equipment for heating the bulk or slurry material and is used in various industries such as non-ferrous metallurgy, ferrous metallurgy, refractory, cement, environmental protection, chemical and paper industries. The rotating calcining kiln is composed of the cylindrical shell, kiln liner, cylinder accessories, sealing device at kiln outlet, transmission device, supporting device with thrust roller, burner, sealing device at kiln inlet, feeding device etc.
The bonding ball in rotary kiln is one major flaw in the operation of rotary kiln, because it will seriously affect the normal production of rotary kiln if failed to process in a timely manner. For kilns with a diameter less than 3M, the biggest ball may block the kiln, so the kiln can only stop running if it could not be ventilated. Specific measures for preventing the ball bonding in rotary kiln are as followings.
1. To reduce the fluctuation of raw material chemical composition
Maintain a strict standard since purchasing raw material, so the unqualified raw material won’t be used in the production process; partition to pile up raw materials. Enhance the effect of heaping and taking the material, reduce segregation of materials and improve the pre-homogenization effect of raw materials. At the same time, cement kiln dust can’t be put in homogenization, instead of mixing in the grinded cement.
2. To stabilize the raw coal content and chemical composition
Maintain a strict standard since purchasing raw coal, so that unqualified raw coal won’t be used in the production process; partition to pile up coal in the coal yard, prevent the blending occurrence of different kinds of coal, so as to ensure the quality of pulverized coal in kiln.
Besides rotating drying kiln, Hongxing Machinery also produces horizontal kiln, calcining kiln, cement rotarying kiln, lime rotary kiln, dry and wet types rotary kiln, etc. Welcome to visit and purchase: email@example.com.

As we all know,the crusher is indispensable important machinery in the mining machinery and quarry. With the progress of the engineering,the types of crushers also change rapidly, which make the clients have too much options to choice. Understand the different crusher superiority, in order to better find broken equipment appropriate oneself in the chaos of the crushing machine.
Impact crusher, which can also be called impact breaker, impact stone crusher, is a machine used for crushing medium-hard and crisp materials relying on the impact energy. It is widely used in many industrial departments such as building material, chemistry and coal for the coarse, medium and fine crushing of medium hard crisp materials such as limestone, dolomite, shale, sandstone, coal, asbestos, graphite and rock salt.
Impact stone crusher, often used as the secondary crusher in an openair quarry. When we finish the primary crushing with the jaw crusher, we need to use the impact crusher to make the second crushing to make the ore smaller. Without the impactor crusher, we can not achieve the goals in an openair quarry. China impact crusher came out at the end of fifties. Now there are five developed trends of impact crusher in China.
1. We need to improve the structure of existing impact crusher, improve the crusher’s ability of crushing medium and hard ores, and improve the convenience of maintenance.
2. Research and develop the new board hammer material with high wear resistance and improve the working life of impact crusher and increase productivity.
3. Adhere to technological innovation and gradually get rid of the simplification and imitation, and improve the our intellectual research of impact crusher
4. Applying modern technology to increase the degree of automation of impact crusher, reduce the labor intensity of workers.
5. In order to adapt to the needs of market, impact crusher develops towards to serial normalized and upsizing.
Gravity spiral chute, a kind of equipment which combine the features of spiral concentrator, spiral chute, shaking table and centrifugal concentrator equipment, is the optimum equipment for mining and mineral processing. Especially for the placer mining in the seaside, river, sand beach and brook, the spiral chute is more desirable. The spiral chute separator has the advantages of light weight, moistureproof, antirust, corrosion-resistant, strong adaptability to the feeding and the fluctuations in concentration, particle size and grade, no noise and so on.
This ore beneficiation equipment applies to the sorting of fine minerals whose particle size is from 0.3 - 0.02 mm such as iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, tungsten ore, tin, tantalumore, niobium ore as well as other non-ferrous metals with differences in the proportion, rare metals and non-metallic minerals. In addition, the spiral chute is easy to operate with stable sorting process, the allowed changing range of feeding concentration is wide, the water consumption is low and other advantages.
In order to meet the greater and greater demand of raw mineral materials, the research and development of new equipment is focusing on precision. Spiral chute separator is the best equipment of mining and beneficiation machines, especially used in the placer mining of waterfront, river, sand beach and creek road. Gravity spiral chute occupies less area, and it is easy to operate.
Its structure is reasonable. Its installation is simple. It occupies less areas, it is easy to operate it. Its handling capacity is big. It is high efficient, concentration ratio and recovery rate. Steel spiral chute is reliable. Besides, it has the following advantages: light weight, moisture, rust, corrosion, no noisy, strong adaptation to fluctuations in the amount, concentration, grain size of the ore.
