Rock Impact crusher is used in crushing all kinds of materials whose fineness is below 500mm,and the pressure resistance around 360mpa. It has the features of big crushing rate, efficient crushing, easy maintenance and cubic shape with final product. It is an ideal mining equipment for high road and water conservancy. With perfect features and good performance, impact crusher is widely used in high road consruction, water conservancy and construction process of gravel and so on. It has a better accability in granite,limestone and cobble,etc.
Rock impact crusher classification:
PF series impact crusher is suitable for crushing hard rocks and its typical outputting size is smaller than 40mm. This model impact crusher such as PF-1010, PF-1210 can crush stone materials with input size between 100mm and 500mm and compressive strength is up to 350Mpa. PF-1214 and PF-1315 impact crushers are suitable for crushing hard materials and the typical output size ≤ 25mm. PFV1010, PFV-1210, PFV-1214, and PFV-1315 impact crushers apply widely to crush concrete, aggregate materials with typical final crushed size ≤ 30mm.

- Q:What is the working principle of the counter crusher?
- The working principle of counter impact crusher:The stone fell into the high-speed rotating wheel directly from the upper part of the machine; at high speed under the action of centrifugal force, and another part by way of diversion in the turntable umbrella flying around the stone to produce high speed impact and high density of crushed stone in the fight against each other, will form a vortex motion between the turntable and the chassis caused by repeatedly hit each other, friction, crushing, direct discharge from the bottom. The formation of closed-circuit multiple cycles, controlled by screening equipment to achieve the required particle size.
- Q:What are the causes of the high temperature of the broken engine oil?
- Improper coordination between parts. The eccentric clearance between the eccentric internal and external bushing and the moving cone of the crusher is broken, or the bevel gear is damaged or the meshing gap is not normal, and it is also the indirect cause of the high temperature of the cone breaking oil.
- Q:What kind of crusher is it?
- We just want to start a business that was also doing a variety of market research, and then look at the many machines, and finally chose the price relative to other high Donglong heavy industries, the quality is also good, I also give you our advice.
- Q:How can a cone crusher achieve the optimum crushing state?
- Do the daily maintenance of cone crusher: such as bearing and horizontal axis lubrication, triangle belt adjustment, thrust bearing, gear clearance inspection inspection, the body part of the bolt fastening, lubrication and adjustment of tubing protection, as long as seriously according to the requirements of the inspection, adjustment, lubrication, fastening, replacement, cleaning door, can ensure the best performance of the crusher work
- Q:What is the crushing principle of the rubber head crusher?
- Definition: a machine that uses a high speed rotating hammer to break the material and break it along a fragile part, such as natural fractures, bedding surfaces, and joint surfaces.
- Q:Operation rules for hammer crusher
- To observe the discharge pit is there more than bulk feed size requirements, if found, should immediately limit feed processing machine.
- Q:Is there a difference between a sand maker and a crusher?
- Sand making machine is a kind of sand and stone dual-purpose machine. It can make sand and gravel, and crusher can only be used for crushed stone, and sand making machine can adjust the size of granule according to customer's requirement.
- Q:Crusher knife and spiral knife which is good
- Spiral knife crusher with spiral tooth cutter, cutter spindle drive, make full use of cutter blades for crushing granular shear stones, and spiral knife crusher cutter and blade are made of cast steel is refined, very durable and hard wearing, the replacement cost is very low. The spiral cutter does not need to be replaced, and even if the blade is worn for a long time, it can continue to be used as long as the knife is repaired in the original place.
- Q:What's wrong with the lubrication system of the crusher? How can we solve this problem?
- Each component of the crusher is worn worse and its operation stability is poor. In the actual operation of the crusher, straight bushing, eccentric shaft, spherical bearings, bearings and other sets of horizontal components due to lubrication is not good because of frequent local overheating and erosion, cracking and even scrap phenomenon, crusher to long-term stable operation.
- Q:What is the working space of the eccentric sleeve and the eccentric shaft of the cone crusher?
- Cone crusher eccentric sleeve and the circular gear connected by oblique key, the eccentric shaft is sleeved on the bushing machine, in order to make the balance of inertia force crushing cone swing movement of the eccentric sleeve and the frame of the support material set along the length of contact, and the eccentric shaft sleeve webbing pressed in the rack bushing, often in the big bevel gear cast on balance block.
