According to the crushing force mode, the crusher machine divides into stone crushers and grinding machine. What's the difference between stone crusher and grinding mill? General speaking, the former one is used to reduce the larger slab into a smaller size, various models of crusher are designed to maximize productivity at the lowest cost. The configuration of the suited crush machine is varied with different crushing stages in the complete crushing circuit, coarse crushing, medium-sized crushing, and fine crushing. The latter one of grinding mill machines are preferred to process fine and extremely fine material, grinding mediums include steel ball, steel rod, gravel, and metal lump so on. Some equipment is capable of crushing and grinding, such as self mill. Discrimination of the working principle 1 Jaw Crusher. The movable jaw plate continually presses against the fixed die at a set time and force to squeeze the rock material caught in it. 2 Cone Crusher. The inner movable cone rotates eccentricity and bumps the outer fixed cone, thus exerting strong crushing force on the ore material. 3 Roll Crusher. The ore material is subjected to continuous crushing and impacting force between the two rollers. 4 Impact Crusher. The ore lump crushed by the impact force of rapidly rotating moving parts. 5 Ore Grinding Machine. The ore slab is crushed by the impact and grinding force of the grinding medium (steel ball, bar, gravel or lump) in the rotating cylinder. Rod mill, pan mill, ball mill, vibration mill, centrifugal mill, etc. Each kind of crusher has various models to suit different applications. Jaw crusher has the features of large crushing ratio, uniform product size, simple structure, reliable work, easy maintenance and economical operation cost. PF-I series impact crusher can crush materials with length less than 100 ~ 500 mm and its compressive strength can reach up to 350 MPA, which has the advantages of large crushing ratio. It is suitable for crushing medium hard materials, such as limestone in cement plant

1 Adjustable fine crusher The adjustable fine crusher mainly consists of a rotary part, guard plate, crushing chamber. The latest fine crusher equipped with a hydraulic device can be very convenient to maintain, save time cost. 2 Jaw crushing type Jaw crusher, is the first choice for primary crushing equipment, with large crushing ratio, uniform product size, simple structure, the relatively small volume can be installed in the tiny space, etc. Therefore, it is widely used in mines, metallurgy, construction material, water conservancy and chemical industries. Compared with cone crusher, jaw type crusher has less investment, less finished flake and lower production cost. Compared with hammer crusher, the wear resistant parts have longer service time, high production efficiency and fewer maintain fees. The common jaw crusher has single toggle type and double toggle type, the former one also called as simple swing crusher, the latter one is called as complex swing crusher. 3. Gyratory crusher The gyratory crusher is a large scale crushing machine which uses the gyratory movement of the crushing cone in the crushing cavity to extrude, squeeze and bend the materials. When the shaft sleeve rotates, the crushing cone is moving in eccentric around the center line of the machine continuously. The productivity of gyratory crusher is higher than that of jaw crusher. There are two types of discharging material and overload insurance, one is mechanical type, by adjusting the nuts on the top of the main shaft to lift up or down the crushing cone, thus change the discharge outlet width, and by cutting the safety pin on the driving pulley to stop overload. Another way is hydraulic gyratory crusher type, by changing the plunger under the hydraulic oil volume can adjust the crushing cone position, thus changing the size of the discharge port. 4 Cone crusher Cone crusher widely used in the metal and mon-metal mines, cement, sand & gravel, aggregate, quarry, metallurgy and other industries. it is suited for fine crushing all kinds of ores and rocks with hardness ≤5 ~ 16, such as iron ore, Non-ferrous metal ore, granite, limestone, quartzite, sandstone, cobblestone, etc. The working principle of cone crusher is the same as that of gyratory crusher, but it is only suitable for medium-sized crushing or fine crushing. The requirements of uniformity of particle size distribution in medium and fine crushing operations are generally higher than that in the coarse crushing operation. Therefore, a section of the parallel zone should be set at the lower part of the crushing cavity. In addition, the rotating speed of the crushing cone should be accelerated so that the material can be squeezed more than once in the parallel zone. The crushing of fine crushing operation is larger than that of coarse crushing operation, so the loose volume after crushing increases greatly. In order to prevent the crushing chamber from blocking, the total discharging cross section must be increased by increasing the diameter of the lower part of the crushing cone without increasing the discharging opening to ensure the required discharging granularity. When the Simon Spring Safety cone crusher overloads, the cone-shaped Shell forces the spring to compress and raise itself in order to enlarge the discharge port and discharge the non-broken material. The adjustment of the discharge opening is carried out by the adjusting cover, and the adjusting cover fixed with the shell can be rotated to drive the shell up or down by the thread on the outer circle, so as to change the size of the discharge opening. The safety and adjustment mode of hydraulic cone crusher is the same as that of hydraulic gyratory crusher. Maintenance of cone crusher 1, Ensure full load production, avoid too coarse product granularity. 2, Optimize the cone crusher productivity by setting reasonable crushing ratio. 3, It is necessary that equipped with an iron removal device. 4, The spring cannot be too heavy pressured, the large pressure may occur shaft broke,  light pressure may cause spring vibrating, influence the crushing efficiency

Right way. First of all, you need to know the crusher materials, the maximum feeding size, finished particle size, handling capacity, crushing environment. With detailed information, JXSC will provide the stone crusher suitable for your production needs

The humidity and hardness of different materials are different. The higher the hardness, the higher the degree of difficulty. For example, granite hardness, the jaw crusher, cone crusher, impact crusher will better. River pebble texture hard wear-resistant, roller crusher crushing effect is better. Brittle materials are more suitable for heavy hammer crushers, such as calcite

2. Sorting machine We can design the crushing plant flow chart when knowing the crushing demand and determine the primary, secondary and tertiary crusher use of which type. crusher. The next step is to choose the type of device. In order to improve efficiency, the general primary crusher processing capacity will be larger than the secondary

1. Control material size The crusher has a maximum feed size. When the feed particle size is too large to the equipment caused serious damage. Whether soft or medium-hard material, both cause different damage. If some of the materials are larger than the maximum feeding size of the crusher, the crusher is easy to appear stuck cavity, blocking phenomenon, affecting the aggregate production efficiency

2. Correct feeding material Many enterprises in order to increase the production capacity and blindly carry out the transformation of the bunker. It resulted in excessive feeding. And that feed too much, it will cause the material too late to break, and the broken material can not be discharged in time, resulting in blocking. Therefore, material cut-off and excessive feeding will affect the capacity of the crusher

3. Maintenance and repairs The daily maintenance and repair of the stone crusher is the key to the effective operation of the equipment. Check the machine regularly and replace the wear-out parts in time

what are the main crusher equipment of river pebble sand

River pebble is a very common stone, which can be used as construction sand after crushing processing. To obtain high quality mechanical sand, when configuring the sand making production line, it is necessary to investigate the manufacturers and quality of equipment to ensure that the selected equipment can meet your requirements

The main processing links of the river pebble sand making production line include feeding, screening, coarse crushing, secondary crushing, sand making, and sand washing. Each production link has special equipment for processing, and each equipment needs to have excellent performance. Luoyang Dahua will introduce you how each link is working, so that you can choose the right type of equipment

The material is sent to the jaw crusher by vibrating feeder for coarse crushing. At the same time of feeding, foreign bodies contained in the material are screened in advance to prevent them from entering the crushing chamber of the crusher and damaging the machine. After discharging from the jaw crusher, the vibrating screen selects the qualified part of broken material and sends it to the secondary crushing equipment (impact crusher, cone crusher) for middle crushing and processing to smaller particles, which is convenient for sand making. The sand making machine impacts the qualified medium crushing material to make sand, adjusts the parameters to the appropriate data according to the requirements of finished products, and produces the finished sand with the expected particle size. When the material comes out of the sand making machine, it will carry dust. The sand washing machine can clean the dust covering on the sand surface and the foreign bodies mixed in the middle, and finally get the clean finished sand stone
