What is granite

Granite is a kind of igneous rock formed by the formation of magma below the surface. The main components are feldspar and quartz. The source of granite is the Latin granum, meaning grain or granules. Because granite is a plutonic rock, it often forms well-developed, visible-grained mineral particles, hence the name. Granite is not easy to weather, beautiful in color, and its appearance can be kept for more than 100 years. Due to its high hardness and wear resistance, it is ideal for outdoor architectural decoration, hall floor or open-air engraving.

Application field of granite

Commercial granite includes the aforementioned granite, gneiss, gneiss granite, granitic schist and what the scholars call the syenite and granodiorite rocks. Rocks of gneiss include minerals, granites, and granular crystals. Commercial granite also includes other similar structures, feldspar crystalline rocks with a small amount of by-component minerals, mainly for decorative users, such as the rock plagioclase known to rock scientists. Gneiss is a coarse crystalline rock composed mainly of silicate minerals. It is inlaid and granular crystal structure. Different types of minerals are arranged in a regular or irregular arrangement. According to the American Society for Testing Materials Classification, granite is divided into ordinary granite and black granite. Ordinary granite is composed of quartz, feldspar, etc., and has black or dark green color due to colored minerals. Generally, it is often colored by feldspar. The dark green or black rock of black granite is made of plagioclase, pyroxene, olivine, and hornblende. Therefore, black granite is divided into three types: porphyrite, diabase, and basalt.

Processing technology

Granite processing technology is based on the characteristics of existing granite processing equipment, and actively refers to the reflection of the majority of users, research and development of practical products, granite processing equipment since its listing, has been loved by customers everywhere.

Granite processing production line has been widely used due to its unique structural design. The choice of crusher equipment mainly depends on the material. The high chromium content determines the hardness and wear resistance of the counterattack plate. The quality of the crusher is the wear resistance inside. The quality of the material. For the design of the granite crushing process, Shanghai Xuanshi uses the crushing equipment of the lamination principle as much as possible to reduce the wear of the wear parts. A typical laminating equipment configuration is a two-stage rupture or rupture plus cone-breaking process configuration.

If the customer has higher requirements on the final finished grain type, it can be configured with a counter-attack to break the sand and stone, thus forming a three-stage crushing process configuration.

Equipment introduction

Granite jaw crusher

granite-jaw-crusher.jpg

The granite jaw crusher is a large-scale compound pendulum type, which is a successful experience of the company in collecting domestic and foreign similar products. It is a rock crusher specially designed for industrial sectors such as mining, smelting, building materials, roads, railways, water quarries and road construction. .

The product has complete specifications, its feed size ranges from 210mm to 1200mm, and the crushing material has a compressive strength of up to 300Mpa. It is the first choice for primary crushing in complete crushing production line. PE series is used for rough breaking, PEX series is used for medium and Fine broken. The granite jaw crusher is powered by an electric motor. The eccentric shaft is driven by a V-belt and a sheave by a motor pulley, so that the movable cymbal reciprocates according to a predetermined trajectory, thereby entering the fixed raft, the movable raft and the side guard. The material in the crushing chamber is broken, and the finished material is discharged through the lower discharge port.

The crushing method of the series jaw crusher is a curved extrusion type. The motor drives the belt and the pulley. The eccentric shaft moves the moving jaw up and down. When the moving jaw rises, the angle between the bracket and the moving jaw becomes larger, thus pushing the moving jaw. The plate approaches the fixed slab, and at the same time the material is crushed, smashed, crushed, etc.; when the moving squat descends, the angle between the bracket and the moving raft becomes smaller, and the moving slab leaves under the action of the tie rod and the spring. The boring plate is fixed, and the crushed material is discharged from the lower mouth of the crushing chamber at this time, and the batch is crushed and discharged as the motor continuously rotates and crushes, thereby realizing mass production.

Granite impact crusher

granite-impact-crusher.jpg

The granite impact crusher is a crushing machine that uses impact energy to break up materials. When the machine is working, the rotor rotates at a high speed under the driving of the motor. When the material enters the action area of ​​the hammer, it collides with the hammer on the rotor, and then is thrown to the counter-attack device to break again, and then from the counter-attack liner. The spring is returned to the action area of ​​the hammer and re-crushed. This process is repeated. The material is broken into the first, second and third, counter-attack chambers from large to small, until the material is broken to the required particle size and discharged from the discharge port. Adjusting the gap between the counter-rack and the rotor can achieve the purpose of changing the material discharge size and material shape.

Performance characteristics of granite impact crusher: 1. Multi-cavity uniform crushing, suitable for crushing hard rock; 2. Low and large feed inlet, easy to arrange production line and increase feed size; 3. New wear-resistant material makes hammer The counter-attack plate and the lining plate have a longer service life; 4. The high-chrome plate hammer and the unique counter-attack lining plate are especially suitable for hard rock crushing, high efficiency and energy saving; 5. Hard rock crushing, high efficiency and energy saving; 6. The whole plate structure makes the row The material is smaller in particle size and cube shape, without internal grain; 7. The shape of the product is cubic, the size of the discharge material is adjustable; 8. Simplify the crushing process; 9. Full hydraulic opening, easy to repair and replace the wearing parts; The feed inlet is large, the crushing chamber is high, the material hardness is high, the block size is large, and the product has less stone powder.

Granite cone crusher

granite-cone-crusher.jpg

Performance characteristics of granite cone crusher:

1. The machine adopts material layering and selection to break. The crushing chamber fills the feeding material, and the material undergoes all-round extrusion, shearing and boring in the crushing chamber to break and self-break, so that the crushing chamber wall avoids direct contact and effectively prevents the lining plates from wearing each other. And to avoid contamination of the material by metal contaminants, so that the degree of the vulnerable parts of the machine is reduced, and the service life of the wear parts is effectively extended, and the crushing ratio is generally more than that of other similar equipment.

2. The crushing ratio of the machine is increased, the granularity of the product is very random, and the size can be adjusted arbitrarily.

3.The crushing force of the PY series spring cone crusher has a certain relationship with the eccentric static torque and the rotational speed of the machine. By adjusting the gap of the crushing chamber, it is convenient to adjust the required crushing ratio. 3. The technical performance index of the machine is stable, and the particle size of the product is almost independent of the wear of the lining.

4. Easy to operate and install. Since the whole machine adopts secondary vibration isolation, the basic vibration is small, the working noise is small, and no large foundation and anchor bolts are needed for installation.

5, good iron performance. Since there is no rigid connection between the moving cone and the transmission mechanism, if the material is mixed with unbreakable objects, the moving cone temporarily stops moving, and the exciter will continue to rotate around the cone shaft, greatly reducing the failure rate.

6. The unique design of the machine simplifies the grinding process and reduces the number of auxiliary equipment. The machine is fully fed, no special feeder is required, and it can be started and stopped at full load. Operation, monitoring and control are very convenient; due to the fine size of the product, no vibrating screen is required to form a closed circuit, which greatly saves equipment and infrastructure investment.

Granite sand making machine works:

granite-sand-making-machine.jpg

Full-center feeding: The material falls into the feeding hopper of the sand making machine, enters the high-speed rotating wheel through the center feeding hole, and is rapidly accelerated in the wheel, its acceleration can reach tens of times of gravity acceleration, and then the high-speed from the wheel The inner shot is firstly impacted with another part of the material that has fallen freely after the rebound, and then impacted on the material lining (stone stone) or the counter-attack block (stone hitting iron), and is rebounded obliquely upward to the top of the vortex chamber, and then changed. The direction of motion, the downward movement of the deflection, and the impact of the material emitted from the impeller flow path form a continuous material curtain. In this way, a piece of material is subjected to two to many chances of impact, friction and grinding and crushing in the vortex breaking chamber. The broken material is discharged from the lower discharge opening. The center feeding is accompanied by the annular waterfall feeding: the material falls into the feeding hopper of the sand making machine, falls through the annular hole, is divided into two materials by the dividing plate, and one of the feeding plates enters the high-speed rotating wheel, and the other The stocks fell from the distribution tray. The material entering the wheel is rapidly accelerated in the wheel, and its acceleration can reach tens of times the acceleration of gravity, and then the high-speed is injected from the wheel. First, it is crushed and broken with another part of the material falling freely around the distributor, and then together Impact on the vortex lining in the vortex chamber, rebounded by the material lining, impacting obliquely upward to the top of the vortex chamber, changing its direction of motion, deflecting downward movement, and colliding with the material emitted from the impeller flow path to form a continuous Material curtain. In this way, a piece of material receives two to many chances of impact, friction and grinding and crushing in the vortex breaking chamber. The broken material is discharged from the lower discharge opening.
