VSI Sand Making Machine is a newly researched equipment, with international advanced level. Technology and modern processing equipment make it a leading role in this industry.Usage:VSI Sand Making Machine is widely used for artificial sand, in metal and non-metal ores, cement, refractory material, bauxite, silicon carbide, glass material, building material.Working Principle:(1) Center Feeding:Raw material falls down into feed hopper, then enter into impeller through central entrance hole. It is accelerated in high-speed impeller, then is thrown out at speed of 60-75m/s. When it hits impact plate, it is crushed. Final products come downwards though outlet. (2) Ring Feeding: Raw material falls down into feed hopper, then through ring, it is divided into two divisions by material-deviding plate. One enters into impellor through the center of material-deviding plate. The other falls down from outside of material-deviding plate. Material, which is thrown out by impellor at speed of 60-75m/s, hits material coming down from outside of material-deviding plate. In this way, material is crushed. ...

We sell cone crusher, rock crusher, stone crusher. Our Product has been developed to crusher high or medium hardness material, such as iron ore ,copper ore, limestone, quartz, granite, and sand stones, ect, in metallurgical, construction, road building,chemical, silicate Industries. This crusher has the advantage of reliable construction, high prod activity, easy adjustment and less cost in operation. The spring release system of crusher acts an overload protection system that allows tramp to pass through the crushing chamber without damage to the crusher, use dry oil, water, two kinds of sealed formation. It made plaster stone and engine oil separated, assured reliable performance. The type of crushing chamber depends upon the size of feed and fineness of the crushed product. The standard type is applied to medium crushing, the medium type is applied to medium or fine crushing, and the short head is applied to fine crushing. The PY series crushers crushes by the change of the gap in the crushing cavity .The gap is opened and closed by the gyration of main shaft, which is derived by motor through cone gears. The PY series cone crusher is of high reduction ratio, high performance, low power consumption, and uniform size products. It has been used in the secondary and tertiary crushing. The crushing action is caused by the closing of the gap between the mantle line (movable) mounted on the central vertical spindle and the concave liners (fixed) mounted on the main frame of the crusher. The gap is opened and closed by the gyration of main shaft, which is driven by the eccentric sleeve. The eccentric sleeve is driven by the motor through elastic coupling, transmission shaft and cone gears. The cone crusher consists of body frame, transmission shaft, eccentric sleeve, bearing, breaking cone, supporting sleeve, adjusting sleeve, feeding part, spring, elastic coupling, lubrication part, electric part. ...

They are widely used in mining, building-material, silicate and chemical industry in the crushing and screening plants.In the Sand-Stone production line, it can send materials to crusher evenly and continuously and at the same time, it can screen materials roughly. It can be used in these areas such as metallurgical industry, coal mining industry, mining-selecting, building, chemical and grinding industry, etc. Vibratory Feeder Feature : Smooth vibration, reliable operation, long service life, low noise, low power consumption, easy to adjust, simple structure, easy to install, light weight, small volume, simple maintenance. contact person: Christina ZhouSkype: zzdhchrisMobile: 86-13526817088 ...

Ball Mill Features: 1) Ball mill is an efficient tool for grinding many materials into fine powder.2) The ball mill is used to grind many kinds of mine and other materials, or to select the mine3) Ball mill is widely used in building material, and chemical industry.4) There are two ways of grinding: the dry way and the wet way.5) Ball mill can be divided into tabular type and flowing type according to differentexpelling mine 6) To use the ball mill, the material to be ground is loaded into the neoprene barrel that contains grinding media.7) As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours. 8) The longer the ball mill runs, the finer the powder will be.9) Ultimate particle size depends entirely on how hard the material you're grinding is, and the time how long the ball mill runs. 10) Our ball mills have been used to grind glass, powder food products, create custom varnishes, make ceramic glaze, powder various chemicals. Ball mill Working Principle: The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished. Don't hesitate to call us if any questions you have or ineterested in our machine. contact person: Christina ZhouSkype: zzdhchrisMobile: 86-13526817088 ...

The flotation machine is the latest design to use the circular tank concept and combines the benefits of circular cells with the unique features of the Minerals mechanism to create the ideal conditions to maximize floatation performance for all roughing, cleaning and scavenging duties. The flotation machine can be used to separate nonferrous metal, ferrous metal, noble metal, nonmetallic mine, chemical material and recycle mine. It features: high inhalation, low power. Each chute can inhale gas, sink magma, separate. There is no need of accessory equipments horizontal equipment. It is easy to change the flow chart. The cycling way of magma is very reasonable. It can reduce the impurities to a great extent. There is automatic equipment on the magma surface. It is easy to adjust. The upward one makes the magma cycle toward upward, which the downward one makes the magma cycle downward. This type of flotation machine is formed by U through solid, hollow shaft inflation, suspension rotor and new type impeller. The cone impeller lean backwards, the blending quantity is big and the pressure head is small, the advantages are: simple structure and low energy consumption. Inside the impeller, there is air distributor, which distributes air into most parts of impeller evenly. When flotation machine works, slurry is inhaled from the bottom of the trough to the space between impellers. Meanwhile, the low_pressure air send by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole trough. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth trough from the overflow weir. Another part of ore slurry flows to lower part of impeller for the re-mis with air. The remained slurry flows to the next trough until becomes residue.  If you are interested in the Flotation Machine please feel free to contact with us at any time. contact person: Christina ZhouSkype: zzdhchrisMobile: 86-13526817088 ...

We produce high weir type, single and double spiral, and immersed single and double spiral classifiers. Our spiral classifiers are widely used in the distribution of ore in closed circuits with ball mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal ore-dressing, and de-sliming and dehydrating in washing. This product features simple structure, reliable working conditions and convenient operation. Because different grains have different specific gravity and sedimentation rates in liquid, this product allows the fine ore to flow in the water, while coarse ore sinks to the bottom. This classifier can filter materials and send coarse materials to the feeding mouth and discharge fine materials from the pipe. The seat of the machine features channel steel material, while the body is armor plated and the spiral axle is made of cast iron for durability. The machine's lifting equipment can be used manually or electronically.
