It can also realize single-person automated operation, which greatly saves the demolition workload and reduces many problems in the construction waste transportation process, which is very important for the urban environment

Gyratory crusher technical guidance: operating points and maintenance strategies

 Gyratory crusher is a common large-scale crushing equipment in mining crushing operations. It is widely favored for its efficient and stable crushing capacity. This article will provide technical guidance on the operating points and maintenance strategies of the gyratory crusher to help readers better understand and apply this equipment.

When operating a gyratory crusher, you must first ensure that the operator has the appropriate professional knowledge and skills. Before starting, the equipment should be comprehensively inspected, including the electrical system, lubrication system, crushing mechanism, etc., to ensure that all components are intact and in normal working condition. After starting, the speed and crushing strength of the crusher should be gradually adjusted, and appropriate crushing parameters should be selected according to the hardness and particle size of the ore to achieve the best crushing effect.

During the crushing process, operators should pay close attention to the operating status of the crusher and detect and handle abnormal situations in a timely manner. For example, if there is abnormal vibration or noise in the crusher, it may be caused by wear or blockage of the crushing mechanism. At this time, the machine should be stopped immediately for inspection, the blockage should be cleared or the worn parts should be replaced. In addition, the oil level and quality of the lubricating oil must be checked regularly to ensure the normal operation of the lubrication system and prevent equipment damage due to poor lubrication.

In addition to operating points, gyratory crusher maintenance strategies are equally important. Maintenance personnel should regularly maintain and repair the equipment, including replacing worn parts, cleaning the inside of the equipment, checking electrical circuits, etc. At the same time, a reasonable maintenance plan must be developed based on the usage of the equipment to ensure that the equipment is always in optimal working condition.

During the maintenance process, you should also pay attention to the following points: First, strengthen the maintenance of the crushing mechanism, regularly check the wear of the crushing teeth, and promptly replace seriously worn tooth plates; second, keep the equipment clean to prevent dust and debris from entering the equipment Internally, it affects the normal operation of the equipment; the third is to strengthen the safety protection of the equipment and set up safety warning signs to ensure the safety of operators.

In addition, with the development of science and technology, the level of intelligence and automation of gyratory crushers continues to improve. Operators and maintenance personnel should actively learn new technologies and knowledge, and master advanced operation and maintenance skills to adapt to the development needs of equipment.

In short, as an important piece of equipment in mining crushing operations, the gyratory crusher’s operation and maintenance are crucial. By mastering the correct operating points and maintenance strategies, the stable operation and efficient crushing of the equipment can be ensured, providing a strong guarantee for the production of the mine

The difference between sand making machine and crusher

 There are significant differences between sand making machines and crushers in many aspects:

Working principle: The working principle of the sand making machine is to feed the raw materials into the machine through the vibrating feeder. The raw materials collide and break with the rotor in the high-speed rotating rotor area of the sand making machine, and then the sand and gravel that meet the requirements are passed through the screening device. Pellets are sent out. The crusher uses a motor to drive a gear device to impact the material at high speed, causing the material to be crushed by a huge impact force.

Scope of application: The sand making machine is mainly used to process machine-made sand, and can perform multiple rounds of sand making based on actual needs. The crusher is widely used in mining, construction, transportation, chemical industry and other fields. It is mainly used for coarse, medium and fine crushing of various materials, as well as crushing and shaping.

Production efficiency: Generally speaking, the production efficiency of the crusher is higher because the particle size of the materials it handles is smaller, and the production efficiency of the crushing equipment is higher. For small and medium-sized production projects, crushers are often used as the main crushing equipment; while large-scale production projects may prefer to use sand making machines.

Feed particle size: The feed particle size of the crusher is usually larger, and the diameter is generally around 1 meter to 2 meters. On the contrary, the feed particle size of the sand making machine is smaller, generally controlled at about 20~30cm, and the feed particle size is clearly defined and cannot exceed the limit set by the equipment, otherwise the equipment may be damaged.

To sum up, there are significant differences between sand making machines and crushers in terms of working principles, application scope, production efficiency and feed particle size. When choosing which equipment to use, comprehensive considerations should be made based on factors such as specific production needs, material characteristics, and equipment performance.

How to choose suitable wear-resistant materials for sand and gravel production lines

 In the sand and gravel production line, the selection of wear-resistant materials is crucial, because equipment in the production line such as jaw crusher, cone crusher, hammer crusher, vibrating screens, etc. will face varying degrees of wear. Here are some factors to consider when choosing wear-resistant materials:

PEV Series European Jaw Crusher

XHP Series Multi Cylinder Hydraulic Cone Crusher

XGN-Z series heavy hammer Crusher

1. Wear characteristic analysis: First, analyze the wear types faced by each equipment in the sand and gravel production line, such as abrasive wear, impact wear, fatigue wear, etc., as well as the hardness, shape, humidity and other characteristics of the material.

2. Equipment working conditions: Consider the working environment of the equipment, such as temperature, humidity, corrosiveness, etc., and select wear-resistant materials that can adapt to these conditions.

3. Material performance requirements: According to the degree of wear and equipment life requirements, select materials with appropriate hardness, toughness, corrosion resistance and other properties. For parts with severe wear, it may be necessary to choose high-performance wear-resistant materials such as high manganese steel, alloy steel or ceramics.

4. Cost-benefit analysis: Weigh the cost and service life of materials. For some non-critical components or components with light wear, lower-cost materials can be selected, while for components with severe wear, high-performance wear-resistant materials should be selected to reduce long-term operating costs.

5. Processing and maintenance: Consider the processability and maintenance convenience of wear-resistant materials. For example, some high-performance wear-resistant materials may require special processing or maintenance measures.

6. Market availability: Consider the supply and market availability of selected materials to ensure timely replenishment or replacement when needed.

7. Regulations and standards: Follow relevant industry standards and regulatory requirements, and select wear-resistant materials that comply with regulations.

8. Practical experience: refer to the experience of using wear-resistant materials in similar production lines or equipment, especially successful cases.

In sand and gravel production lines, commonly used wear-resistant materials include:

- High manganese steel: suitable for crusher parts with severe impact wear.

- Alloy steel: suitable for a variety of wear environments and has good overall performance.

- Ceramics: Suitable for occasions with very serious wear, such as the manufacture of crusher linings or grinding balls.

- Nickel carbide: suitable for high stress wear and corrosive wear environments.

- Wear-resistant rubber: suitable for vibrating screen mesh or situations where shock absorption is required.

What standards does excellent machine-made sand meet?

 Machine-made sand definition

According to the national standard, all machine-made sand and mixed sand that have been treated with soil removal are collectively referred to as artificial sand. The specific definition of machine-made sand is mechanically crushed and sieved rock particles with a particle size of less than 4.75mm, but does not include soft rock and weathered rock particles.(Xingaonai group​ , Stone crusher)

Specifications of machine-made sand

At present, the artificial sand is basically medium-coarse sand, the fineness modulus is between 2.6 and 3.6, the particle gradation is stable and adjustable, and it contains a certain amount of stone powder. Triangular or rectangular body with rough surface and sharp edges and corners. However, due to the different production sources of machine-made sand and the different equipment and processes for producing and processing machine-made sand, the grain type and gradation of produced machine-made sand may be very different. For example, some machine-made sand has more flaky particles, and some The particle gradation of machine-made sand is large at both ends and small in the middle, but as long as it can meet all the technical indicators of artificial sand in the national standard, it can be used in concrete and mortar. Man-made sand that does not meet the technical requirements of the national standard cannot be used, because the grain shape and gradation of machine-made sand can be adjusted and improved. In this regard, there is an essential difference between artificial sand and natural sand. The blending ratio of mixed sand will reduce its above-mentioned characteristics.

The specifications of machine-made sand are divided into four types: coarse, medium, fine and extra fine according to the fineness modulus (Mx):

The fineness modulus of coarse sand is: 3.7-3.1, the average particle size is above 0.5mm; the fineness modulus of medium sand is: 3.0-2.3, the average particle size is 0.5mm-0.35mm, the fineness modulus of fine sand is The number is: 2.2-1.6, the average particle size is 0.35mm-0.25mm; the fineness modulus of ultra-fine sand is: 1.5-0.7, the average particle size is below 0.25mm; the larger the fineness modulus, the coarser the sand; The smaller the fineness modulus, the finer the sand.

Grades and uses of machine-made sand

(1) Grade: The grade of machine-made sand is divided into three grades according to its skill requirements: Ⅰ, Ⅱ, and Ⅲ.

(2) Use: Type I sand is suitable for concrete with a strength grade greater than C60; Type II sand is suitable for concrete with a strength grade of C30-C60 and frost resistance, impermeability or other requirements; Type III sand is suitable for concrete with a strength grade less than C30 with construction mortar;

Machine-made sand requirements

The particle size of machine-made sand is between 4.75-0.15mm, and there is a certain proportion limit for stone powder smaller than 0.075mm. Its particle size is divided into: 4.75, 2.36, 1.18, 0.60, 0.30, 0.15. The particle size should be continuous, and each particle size should have a certain proportion. The particle shape should be cubic as much as possible, and there are certain restrictions on the content of needle flakes.

Grain Grading of Manufactured Sand

The particle gradation of sand refers to the matching ratio of sand size particles. If it is sand of the same thickness, the gap between them will be larger; if the sand of two particle sizes is matched, the gap between them will be reduced; if the sand of three particle sizes is matched, the gap will be smaller. It can be seen that the porosity of the sand depends on the matching degree of the particle sizes of the sand materials. Well-graded sand can not only save cement, but also improve the compactness and strength of concrete and mortar.

Raw material of machine-made sand

Sand-making raw materials for machine-made sand are usually granite, basalt, river pebbles, pebbles, andesite, rhyolite, diabase, diorite, sandstone, limestone and other varieties. The machine-made sand made by it is classified according to the type of rock, and has differences in strength and use.

Grain type requirements of machine-made sand

The mine configuration requires that the particles of the crushed materials be fine. Generally speaking, the needle-like materials are easier to be ground when they enter the mill. The requirements for building gravel are just the opposite, and there are strict proportion restrictions on needle flakes. The reason is mainly because the cube particles have edges and corners, and the edges and corners can play the role of mutual locking between particles. At the same time, cubic particles have stronger adhesion than needle-like particles and round particles, and occupy a larger surface area.

Characteristics of machine-made sand

The characteristics of concrete prepared with artificial sand are: the slump decreases, and the 28d standard strength of the concrete increases; if the slump remains unchanged, the water demand increases; but when the water-cement ratio increases without increasing the cement, generally In this case, the measured strength of concrete does not decrease. Concrete proportioning design is carried out according to the law of natural sand, artificial sand requires a large amount of water, has poor workability, and is prone to bleeding, especially in low-strength concrete with less cement consumption; and if artificial sand is used according to the Features Concrete proportioning design, reasonable use of stone powder in artificial sand and adjustment of sand rate in artificial sand can completely prepare concrete with good workability. The proportioning design method of the ordinary concrete proportioning design regulation is completely applicable to artificial sand. The fineness modulus of artificial sand most suitable for preparing concrete is 2.6-3.0, and the gradation is zone 2.
