With the development of the stone crushing machine, the occurrence of new materials and advanced techniques, more and more granite crushers are manufactured in the market, and the differences in their prices are widening.

Granite is a kind of igneous rock, also known as acid crystalline plutonic rock, which belongs to hard stone. It is made of feldspar, quartz, and a small amount of mica. Granite is dense and has a granular structure.

The main component of granite is silicon dioxide, which has a hardness of 6 to 7 according to Mohs hardness. Natural granite has different shapes and needs to be crushed to meet the demand for materials in various fields.

The color of granite depends on the colors and distributions of feldspar, a small amount of mica, and the melanocratic mineral. The colors are usually gray, red, roseate, or gray alternating with red.

After processing and polishing, the surface of granite will form a beautiful speckled pattern with different shades of color. The pattern is characterized by fine and uniform grains, with star-liked mica highlights and sparkling quartz crystals.

It is often used as the primary crushing equipment of granite and the large granite can be crushed to a particle size of less than 100 mm. During the crushing process of granite, a piece of granite is crushed by shearing, breaking, splitting and extrusion which makes the finished product more solid.

During the working process, granite jaw crusher runs stably with lower faulty rate and longer service life. It also has the advantages of small investment, large crushing ratio, wide applications, and high working efficiency.

It not only realizes the selective crushing of materials but also significantly increases the product fines ratio and cube content, greatly reducing the needle-like materials and the wear on the parts.

In addition, the cone crusher also uses a modular design. Through the replacement of the cavity type, it can realize the conversion of coarse, medium and fine crushing, improve the production efficiency, and also meet the large production demand.

The discharge port, screen and key parts of the cone crusher are equipped with a spray system, which can humidify the dry material, increase its weight, and effectively inhibit and reduce dust pollution.

The dilution of noise first passes through the environmental protection layer built into the cone crusher. This wear-resistant buffer layer not only dilutes the noise but also protects the machine and reduces the noise around workers.

However, the hammer and counter-attack plate of the impact crusher are easy to wear. Especially when crushing hard rocks such as granite, the wear is more serious and the wear parts need to be replaced frequently, which not only increases production costs but also extends downtime.

The granite aggregate processed by the sand making machine has a solid shape, strong adhesion and long durability, and is widely used in highways, railways, bridges, airports, real estate and other fields.

If the material requirements are low, the jaw crusher and the cone crusher are required to crush the granite. Or else, the sand making machine should be added for the final shaping of the material.

The granite sand making machine is stable in operation. the failure rate is very small, the output of sand making machine is huge, and the finished products are uniform with cubic shape, which is favored by downstream users.

The semi-mobile granite crushing plant is mainly designed to eliminate the problems that occurred in the actual crushing site for users. The integrated unit installation and flexible movement solve the obstacles of crushing operation for the customer, and the operation saves much time and effort.

The equipment adopts a half vehicle-mounted structure with tires as the chassis. The flexible collocation allows it to be used in combination with different crushers to meet the different needs of customers.

Mr. Paul from the UK sent his feedback: "since the introduction of this semi-mobile granite crushing machine in our plant, the output of our entire production line has stabilized. Our company is very grateful for the benefits this equipment provides for us."

Based on the traditional semi-mobile crusher and combined with the properties of granite, the portable granite crushing plant is specifically designed. It has significant advantages in both structure and performance, arousing the attention and favor of users at home and abroad.

Portable granite crushing plant is mainly composed of four parts: feeding system, crushing system, screening system and conveying system. The purpose of the feeding system is to feed granite materials into the crusher or the screening machine; the crushing system is used to crush granite; the screening system is used to granite gravel screening; and the conveying system is used to transport the finished gravel products.

The materials that larger than the particles are returned to the sand making machine and continue to be crushed. Small substances are sent to the sand washing machine for cleaning. The cleaned materials are sent to the finished product pile by the conveyor.

The finished product of the sand and gravel treated by the production line has a uniform particle size, good granular shape and low output rate of stone powder, which can fully meet the demand of strict requirements.

Granite is a material with high hardness and high silicon content, which is difficult to crush in actual crushing operations, or it is relatively high in crushing cost. If an unsuitable crusher is selected, the damage speed of the wear parts will be accelerated, and it will need to be replaced even in a few days, and the running cost will increase.

Since granite is a brittle material, the improper crusher will increase the content of the needle-like material and increase the internal crack of the finished product, thereby reducing the application range and increasing the production cost.

Two or more crusher types will be used in the granite crushing process, so the combination of crusher is especially important. A good production line will make the crushing process run more smoothly, and save labor power and material resources while increasing production.

The crushing of ore cannot avoid the generation of dust. The diffusion of dust will not only pollute the environment, but may cause downtime if it is slightly inadvertent. Therefore, when the crusher is selected, its sealing system and dust control methods should be perfect.

Under the background of environmental protection, reducing noise interference is also one of the channels for environmental protection. Therefore, when choosing a crusher, noise issues should also be taken into account.

Rock crushers have a wide range of suitable material to choose from, whether its soft or hard, or even very hard, rock crushers can reduce those large rocks into smaller rocks, gravel, or even rock dust.Here are some typical materials that break or compress by industry crushers, such as Granite, quartz stone, river pebble, limestone, calcite, concrete, dolomite, iron ore, silicon ore, basalt and other mines, rocks and slag.

Understanding the stages of crushing process and the types of crushers that best fit each stage can simplifies your equipment selection. Each type of crusher is different and used to achieve a certain end result.

Similarly, a certain output is expected at the end of each crushing stage for the next phase of the process. Aggregate producers who pair the correct crusher to the correct stage will be the most efficient and, in turn, the most profitable.

A jaw crusher is a compression type of crusher. Material is reduced by squeezing the feed material between a moving piece of steel and a stationary piece. The discharge size is controlled by the setting or the space between those two pieces of steel. The tighter the setting, the smaller the output size and the lower the throughput capacity.

As a compression crusher, jaw crushers generally produce the coarsest material because they break the rock by the natural inherent lines of weakness. Jaw crushers are an excellent primary crusher when used to prepare rock for subsequent processing stages.

Although the chamber is round in shape, the moving piece of steel is not meant to rotate. Instead, a wedge is driven around to create compression on one side of the chamber and discharge opening on the opposite side. Cone crushers are used in secondary and tertiary roles as an alternative to impact crushers when shape is an important requirement, but the proportion of fines produced needs to be minimized.

An impact crusher uses mass and velocity to break down feed material. First, the feed material is reduced as it enters the crusher with the rotating blow bars or hammers in the rotor. The secondary breakage occurs as the material is accelerated into the stationary aprons or breaker plates.

Impact crushers tend to be used where shape is a critical requirement and the feed material is not very abrasive. The crushing action of an impact crusher breaks a rock along natural cleavage planes, giving rise to better product quality in terms of shape.

Most aggregate producers are well acquainted with the selection of crushing equipment and know it is possible to select a piece of equipment based solely on spec sheets and gradation calculations. Still, theoretical conclusions must always be weighed against practical experience regarding the material at hand and of the operational, maintenance and economical aspects of different solutions.

The duty of the primary crusher is, above all, to make it possible to transport material on a conveyor belt. In most aggregate crushing plants, primary crushing is carried out in a jaw crusher, although a gyratory primary crusher may be used. If material is easily crushed and not excessively abrasive, an impact breaker could also be the best choice.

The most important characteristics of a primary crusher are the capacity and the ability to accept raw material without blockages. A large primary crusher is more expensive to purchase than a smaller machine. For this reason, investment cost calculations for primary crushers are weighed against the costs of blasting raw material to a smaller size.

A pit-portable primary crusher can be an economically sound solution in cases where the producer is crushing at the quarry face. In modern plants, it is often advantageous to use a moveable primary crusher so it can follow the movement of the face where raw material is extracted.

The purpose of intermediate crushing is to produce various coarser fractions or to prepare material for final crushing. If the intermediate crusher is used to make railway ballast, product quality is important.

In other cases, there are normally no quality requirements, although the product must be suitable for fine crushing. In most cases, the objective is to obtain the greatest possible reduction at the lowest possible cost.

In most cases, the fine crushing and cubicization functions are combined in a single crushing stage. The selection of a crusher for tertiary crushing calls for both practical experience and theoretical know-how. This is where producers should be sure to call in an experienced applications specialist to make sure a system is properly engineered.

The size requirement of the primary rock crusher is a function of grizzly openings, ore chute configuration, required throughput, ore moisture, and other factors. Usually, primary crushers are sized by the ability to accept the largest expected ore fragment. Jaw crushers are usually preferred as primary crushers in small installations due to the inherent mechanical simplicity and ease of operation of these machines. Additionally, jaw crushers wearing parts are relatively uncomplicated castings and tend to cost less per unit weight of metal than more complicated gyratory crusher castings. The primary crusher must be designed so that adequate surge capacity is present beneath the crusher. An ore stockpile after primary crushing is desirable but is not always possible to include in a compact design.

Many times the single heaviest equipment item in the entire plant is the primary crusher mainframe. The ability to transport the crusher main frame sometimes limits crusher size, particularly in remote locations having limited accessibility.

In a smaller installation, the crushing plant should be designed with the minimum number of required equipment items. Usually, a crushing plant that can process 1000s of metric tons per operating day will consist of a single primary crusher, a single screen, a single secondary cone crusher, and associated conveyor belts. The discharge from both primary and secondary crushers is directed to the screen. Screen oversize serves as feed to the secondary crusher while screen undersize is the finished product. For throughputs of 500 to 1,000 metric tons per operating day (usually 2 shifts), a closed circuit tertiary cone crusher is usually added to the crushing circuit outlined above. This approach, with the addition of a duplicate screen associated with the tertiary cone crusher, has proven to be effective even on ores having relatively high moisture contents. Provided screen decks are correctly selected, the moist fine material in the incoming ore tends to be removed in the screening stages and therefore does not enter into subsequent crushing units.

All crusher cavities and major ore transfer points should be equipped with a jib-type crane or hydraulic rock tongs to facilitate the removal of chokes. In addition, secondary crushers must be protected from tramp iron by suspended magnets or magnetic head pulleys. The location of these magnets should be such that recycling of magnetic material back into the system is not possible.

Crushing plants for the tonnages indicated may be considered to be standardized. It is not prudent to spend money researching crusher abrasion indices or determining operating kilowatt consumptions for the required particle size reduction in a proposed small crushing plant. Crushing installations usually are operated to produce the required mill tonnage at a specified size distribution under conditions of varying ore hardness by the variation of the number of operating hours per day. It is normal practice to generously size a small crushing plant so that the daily design crushing tonnage can be produced in one, or at most two, operating shifts per working day.
