PF Series Impact Crusher is one kind of equipment to crushing the brittle material which compression strength no more than 350 Map, the advantage including high crushing ratio, uniform product grain and low over crushing, low energy consumption, high adjustment range of product grain size and optional crushing etc, which is mainly used in mine, metallurgy, cement, construction material, coal etc for secondary crushing and fine crushing the medium hardness material. Application: Metallurgy, construction material, mine, beneficiation and large block material crushing. Our advantages: 1. Large feeding port and high crushing cavity, suitable to crushing the material with high hardness and big grain size, and less powder. 2. The gap between impact plate and hammer plate is adjustable, so the discharging grain size can be effective control and the grain shape is well. 3. The hammer, impact plate and lining plate are made of new type abrasion-proof material with long working life and impact protection, wear protection. 4. Because of the function of three-stage crushing and plastic, so the crushing ratio is high, and the product shape is cube and can optional crushing. 5. The multi-function hydraulic station has many function of hydraulic discharge gap with high speed, impact plate stable vibration and the body open automatically. The PF series impact crusher is mainly compose of the rack, driving system, rotor, hammer and impact plate etc. The main feature including: 1.Rack: It composed by two parts of upper and lower with connection by bolt. All the parts contact the crushed material in the rack have set replaceable lining plate. 2. Driving System: The main shaft and rotor are driving by motor through belt then doing the high speed rotary motion. 3. Rotor: It adopts entire cast steel structure with high mass force, solid and durable, convenient to install the hammer. 4. Impact Plate: It is made from new type abrasion material and hanging freely inside the equipment. One end connect with the two sides of the rack through hanging shaft hinge, another end is bearing in the upper rack cone gasket through stay bolt which is adopt a sphere gasket, it can prevent the equipment damage by non-crushing material when crushing material. 5. Hammer: It is made from new type abrasion material and fixed on the rotor through wedge block

Dehong jaw crusher series are based on years experience and technology development. The continuous improvement and refinement has made them the preferred jaw crusher for professionals and our customers. They can meet most crushing requirements in primary and secondary crushing, and the largest compression resistance of the material is 320mpa. This series are widely used in stone mining, metallurgical, construction, smelting, hydraulic and chemical industries, etc.

The Zenith VSI crusher is widely used for crushing of hard and crispy materials, such as rocks, grinding materials, refractory materials, cement clinkers, quartzite, iron ores and concrete aggregates.The stone crusher is especially suitable for the sand and sandstone making for construction and road paving. The crusher can cycle many times with the close circuit and the sieve device will control the granularity of finished products.ThisVsi crusher is applied widely for the powder process of mineral product including mental and non-metal ore, fireproof material, bauxite, diamond dust, glass raw materials, architectural materials, artificial sand and all kinds of metal ore materials, especially which has more advantages than any other machines in processing the more and most hard materials VSI Crusher Features: 1.

Product Introduction Vertical shaft impact crusher is also named Sand making machine which features is a unique combination of rotor design, wear material and crushing equipment design. This combination has proved revolutionary in improving capacity, gaining superior product shape quality and in reducing operating and wear costs. Impact crusher is a high-efficient rock crushing equipment with home and international leading level. The machine is developed by introducing the crushing theory and technology from Barmag Company of America and combining the actual situation of sand making. It is widely used for crushing of hard and crispy materials, such as rocks, grinding materials, refractory materials, cement clinkers, quartzite, iron ores and concrete aggregates. It is especially suitable for the sand and sandstone making for construction and road paving. It is more suitable for crushing mid-hardness materials and high-hardness materials. Its product is cubic, and the density of piling up is high and the iron pollution is low. It can protect our environment better with the working noise less than 75 decibels and little dust pollution. Working Principle Material falls into the high speed turning impellers from the top of machine and crushes with the material distributed around the impeller under the effect of high speed centrifugal force. After the impact with each other, the material is crushed between impeller and cabinet and is discharged from the bottom. It can cycle many times with the close circuit and the sieve device will control the granularity of finished products. Features 1. Excellent performance and high final fineness 2. Safe and user-friendly 3. Smooth and quiet operation 4. Minimum maintenance 5. Heavy duty design 6. Long service life 7. Standard replacement parts 8. Cost effective 9. Cubically shaped product 10. High productivity Contact Us Fangda Industrial is a famous crusher supplier in China, and the price is competitive. Welcome customers to visit for cooperation.

Appliance: Vertical impact crusher is also known as sand making machine is applied widely for the powder process of mineral product including mental and non-metal ore, fireproof material, bauxite, diamond dust, glass raw materials, architectural materials, artificial sand and all kinds of metal ore materials, especially which has more advantages than any other machines in processing the more and most hard materials. Features and Benefits: 1.High efficiency and low consumption 2.Primary and second crushing capacity 3.More and most hard materials can be crushed4.Cubic shaped final product 5.Little noise and dust pollution 6.Convenient performance, maintenance, installation7.Simple structure, low production cost. Working Principle: Vertical impact crusher includes hopper, classifier, whirl pool cavity, impeller, main bearing assembly base, transmission device and motor etc. Operating principle is as follows: the materials enter the crusher through feeder hopper, which is divided into two parts, one part through the middle of classifier entering into the rotating impeller at high speed, then accelerated, whose speed can reach hundreds of acceleration, then is shot through the tunnels around the impeller by the speed of 60-75 meter/second. First the materials will impact with some materials fallen around classifier, then impact on the whirlpool cavity scale board together, then will be rebounded and impact on the top of the whirlpool cavity, then changes its direction and goes down, forms continual material layers with the materials shot from the impeller. Therefore some materials will be impacted, crusher, milled twice or more times in the whirlpool cavity, then crushed materials will be excluded through the bottom discharging hole. This can from a closed circulation through the circular classifier system; in general, materials can be crushed into 20 mesh through thrice circulation. Airflow self-circulation in the whirlpool cavity can eliminate the dust pollution well.
