limestone crusher machine is a general term, mainly refers to the collective name of some crushers used to crush limestone. Generally refers to jaw crusher, impact crusher and impact crusher. This article mainly introduces what is a limestone crusher machine, the working process of the limestone crusher machine, and the characteristics of the limestone crusher machine.
What is a limestone crusher machine?
The main component of limestone is calcium carbonate. Lime and limestone are used in large quantities as building materials and are also important raw materials for many industries. At the same time, the current mainstream limestone crusher machine has many years of manufacturing experience, and has successfully used many limestone production lines.
Engineers with skilled limestone crusher machines can also design a complete set of limestone crushing systems according to the requirements of users, as well as design and installation, commissioning and trial production of limestone crushing systems, as well as worker training and a complete set of pre-sale, in-sale, After-sales process.
The performance of the limestone crusher machine is stable and reliable, the process is simplified, the structure is simple, the maintenance is convenient, the production capacity is also large, and the life of the hammer head is also longer. It is widely used in fine crushing of granite, basalt, limestone, cobblestone, cement clinker, quartz stone, iron ore and these minerals.
Limestone processing process and use?
The processing of limestone is divided into two parts: crushing and grinding
The large pieces of limestone raw materials are evenly sent to the limestone crusher machine by the vibrating feeder through the silo for crushing. The material belt is sent back to the limestone crusher machine for crushing again.
Due to the low hardness of limestone, in the direction of choosing limestone crusher machine, jaw crusher and impact crusher can be selected, which can be used alone or in combination.
Different industries have different requirements for the fineness of limestone. When grinding and processing limestone powder, the corresponding limestone pulverizer can be matched according to the specific mesh requirements of customers.
Generally speaking, the products after limestone grinding and deep processing include nano calcium, light calcium, calcium hydroxide, lime calcium powder, edible calcium, medical calcium, calcium oxide powder and lime products with high activity, high content and high surface area. The industries involved and their main uses are:
Metallurgy: mainly requires high content of active calcium oxide and low content of silicon and magnesium
Aquaculture field: mainly plays the role of disinfection and deodorization
In the field of plastics: mainly plays the role of defoaming and coupling
In the field of construction: can play the role of painting walls
Advantages of limestone sand making?
Limestone is a low-hardness stone. When selecting limestone crusher machine equipment, if the particle size needs to be mined larger, jaw crusher is commonly used. In the middle crushing, the impact crusher is used to crush the coarse limestone into small stones again.
If you use limestone to make sand, you can choose an impact crusher to crush the finely crushed limestone into 1-5 mm sand. The impact crusher is a machine with shaping sand making, uniform discharge particle size, and particle size conforming to the standard of construction sand.
Limestone sand making is made from the waste stone powder of the limestone stone plant, which is a waste of surplus resources, which are crushed, washed and screened by a limestone crusher machine. According to the process flow, the whole use of the limestone crusher machine for sand making has the following advantages:
- The limestone crusher machine can stably and effectively produce limestone specifications that meet the engineering technical requirements according to the engineering quality requirements.
- The particle size and fineness of the sand can be adjusted according to the needs of the project and in combination with the requirements of making concrete
- The strength of concrete and the adhesion of gel materials such as cement require rough surface and irregular shape of sand and gravel, and limestone crusher machine can meet these requirements
- The production of limestone crusher machine can be combined with the production process of crushed stone, which is conducive to the reuse of comprehensive resources, reducing pollution and reducing the use cost of limestone crusher machine
The process of limestone crushing treatment?
Machine-made sand and gravel aggregate are all crushed by rock or river rock. The main raw material of rock is limestone, which is widely distributed and very common. Usually the large limestone mined on the mountain is crushed by a limestone crusher machine and processed into stones or machine-made sand of different specifications. The limestone crusher machine can be divided into coarse crushing equipment, medium crushing equipment and fine crushing equipment according to the size of the output material.
Coarse crushing equipment
In a complete limestone crushing production line, the coarse crushing equipment, as the first crushing equipment, can crush the mined large pieces of limestone into 125 mm to 400 mm size stones. Common coarse crushing equipment There are jaw crushers.
Secondary crushing equipment
After being processed by the primary crushing equipment, under the transport of the belt conveyor, it enters the secondary crushing equipment. Stones between fifty and one hundred millimeters.
Fine crushing equipment
After the first two crushing processes, the small pieces of limestone entering can be crushed into stones or machine-made sand of 5 mm to 25 mm under the action of the fine crushing equipment. After being screened by the vibrating screen, the whole limestone crusher machine The crushing process is complete.
What are the performance characteristics of limestone crusher machine?
The working principle of the limestone crusher machine: the motor drives the rotor to rotate at a high speed through the V-belt and the large pulley; the material to be crushed is fed into the crushing cavity by the feeding device through the feeding port, and the high-speed rotating rotor drives the hammer to strike the material first; obtain kinetic energy After the material, it hits the counterattack plate at high speed for secondary crushing; after the collision rebounds, it is hit again by the hammer head or collides with other materials.
In the process of collision, the material gradually moves to the movable impact plate at the lower part of the crushing chamber. When the particle size of the material is smaller than the gap between the hammer head and the movable impact plate, it will break away from the crushing chamber under the pressure of its own weight and other materials, thus ending a complete crushing process. After the discharged material is screened by the screening equipment, the material larger than the standard is sent to the limestone crusher machine for secondary crushing.
The performance characteristics of limestone crusher machine
The hammer crusher has large feeding granularity and small discharging granularity, which can realize three-stage crushing, and realize the function of one crusher to complete two crushers. Therefore, it can save 35% of the cost, and it is a device with low energy consumption and low investment.
Hammer crusher is a crushing machine manufactured and produced after optimized design on the basis of ordinary hammer crusher, impact crusher, vertical shaft hammer crusher and various mechanical principles of crushing stone with hammer. product.
At the same time, the limestone crusher machine should use sophisticated accessories, generally using chrome alloy.
The limestone crusher machine can crush wet materials, which can reduce dust pollution and protect the health of workers and the environment.
The technological process of limestone crushing production line?
Limestone is processed into stone by a limestone crusher machine. Generally speaking, the process of coarse crushing, medium and fine crushing, and screening is required. The particle size of raw materials, production demand, budget, finished product, and site must also be considered. In addition, before processing limestone, Enterprises must first go through relevant legal procedures, choose a suitable site, and at the same time meet the conditions of convenient transportation and water and electricity, build infrastructure, cement platforms, etc. The complete limestone production line plan is generally as follows:
Option 1: Multi-stage crushing type
Master batch stacking, vibrating feeder, jaw crusher, belt conveyor, impact crusher, belt conveyor, vibrating screen, qualified material, belt conveyor, silo stack live
Option 2: One-shot molding
Master batch stacking, vibrating feeder. hammer crusher, belt conveyor, vibrating screen, qualified material
What equipment can be selected for limestone crusher machine?
Coarse crushing–jaw crusher
As a kind of coarse crushing equipment, its crushing cavity is deep, there is no dead zone, and there is no need to worry about clogging the material due to the large particle size of the raw material. At the same time, the adjustment of the discharge port is also different from the traditional adjustment method of the plug board. Adjusting the discharge port with a wedge reduces the labor intensity of the staff and the time for downtime adjustment. The finished particle size adjustment range is 10 to 350 mm, and the particle size is uniform, which is helpful for secondary crushing treatment.
In addition, for high-hardness stone, key components such as jaws and linings are made of high-quality alloy materials. The whole machine is durable, the motion parameters are optimized, and the crushing ratio is larger, which is very suitable for crushing large limestone.
Medium crushing – impact crusher
The crushing cavity of the impact crusher adopts an involute type high-efficiency large crushing cavity design. After multiple impact crushing in this cavity, the particle shape of the material tends to be more cubic, which can better meet the production requirements of high-quality aggregates.
Fine crushing — impact crusher
It adopts the working principle of “shooting stone with stone” and “shooting iron with stone”, which is suitable for the requirements of high standard materials. The impact angle of the deep cavity impeller and the crushing cavity is improved, and the processing capacity is increased. The particle size of the finished product is less than 4.7 mm, the setting effect is good, and the wearing parts have a long service life. At the same time, the combined throwing head is adopted, only the worn parts need to be replaced, and the cost of use is reduced.
