The sand and gravel crushing production line typically refers to the specific crushing equipment used to grind and crush ore, reducing its particle size to the required range for subsequent resource recycling operations. However, whether it is during the production of the sand and gravel production line or in the ore field where the original ore is stacked with high processing intensity and a wide footprint. In the past, our crushing production sites were always filled with dust, creating a harsh environment. The dust generated during the crushing process spread into the air with the airflow, causing serious environmental pollution and posing a hazard to the health of the operators.
Therefore, in recent years, the country has increased environmental management and advocated the establishment of environmentally friendly stone crushing plants. Dust suppression treatment has become a necessary condition for the smooth operation of stone plants. So what are the dust control solutions commonly used in establishing sand and gravel crushing production lines? Let's find out now!
1. Suppress dust when transporting materials: The jaw crusher to the pre-screening workshop and the semi-finished material belt outlet are surrounded by fully enclosed light-colored steel, which reduces dust pollution and noise by more than 50% compared to traditional open-air production.
2. Capture and collect released dust: Select appropriate dust collector equipment according to the crusher model and process characteristics, such as bag dust collector, wet dust collector, etc. Placing dust removal equipment near the source of dust generation can capture dust to the greatest extent.
3. Spray system: Choose to install two water spray devices at the inlet, outlet and crushing cavity of the crusher. The two water spray heads at the feed port point toward the inlet; The two water spray heads at the discharge port form a certain angle relative to each other, so that the sprayed water is in a cross state to achieve the ideal effect.
4. Dust suction device: Install dust suction devices at the discharge port and the inspection port of the crusher equipment. The dust hood of the discharge port should be installed about 1000mm away from the discharge port. The plane of the dust hood should be perpendicular to the direction of dust flow; The connection between the dust hood and the blower of the crusher equipment maintenance port can be designed to be a flexible telescopic pipe making it easy to refuel the crusher and perform routine maintenance.
5. Optimize the structure: The structure can be modified and optimized in places with relatively large slopes such as equipment feed hoppers, protective covers, chutes, etc. The first is to reduce the inclination angle of the chute to reduce the height difference of the materials; The second is to improve the structure of the crusher. While the overall size of the equipment remains unchanged, the number of teeth on the tooth plate is increased and the tooth shape becomes relatively smaller.
6. Design improvement: Use reasonable process plans and equipment for production, and try to use closed transportation methods during material transportation. In addition, the screen must be cleaned in time to prevent clogging, so that some small particles and dust can be screened out before the material enters the crusher.
In summary, the solution of the sand and gravel crushing production line should implement the principle of prevention first, minimize the dust link in the overall plan, and strictly control dust pollution during raw material processing and transfer; Select equipment with less dust, and use spraying dust reduction and dust removal methods in the early stages. The implementation of the above measures can effectively improve the operating environment of the sand and gravel production line and improve the level of environmental protection.
As key equipment for producing artificial sand, the sand making machine has been widely used in construction, roads, railways, water conservancy and other engineering fields. The quality of sand making machine products has a significant impact on the safety and durability of engineering construction, while the sand production rate of the sand making machine is one of the important indicators directly related to its production efficiency and product quality. However, many times we find that the capacity of the sand making machine does not achieve the expected results, and even encounters the problem of low output. This article will delve into the reasons for the low production of sand making machine and propose corresponding solutions to help you improve the sand output rate of the sand making machine.
1. Analysis of the reasons for the low capacity of sand making machine
(1) . Equipment aging:
Long-term use or improper maintenance may cause the sand making machine to age, thus affecting its capacity. Aging of equipment will cause parts to wear, loosen, or even malfunction, thereby reducing the crushing efficiency of the sand making machine.
(2) . Raw material issues:
If the raw material used for sand making is too hard or viscous, it may have a negative impact on the capacity of the sand making machine. Raw materials with high hardness are difficult to crush, while raw materials with high viscosity tend to adhere to the crushing wall, affecting the sand production rate. Uncertainty in the supply of raw materials can also lead to production disruptions, which in turn reduces output and increases production costs.
(3) . Unreasonable design:
The design of the sand making machine has an important impact on its capacity. If there are flaws in the design, it will directly lead to a decrease in production. For example, unreasonable crushing cavity structure, rotor design, feeding method, etc. will affect the crushing effect of the sand making machine.
(4) . Improper operation:
Incorrect operating methods or parameter settings may affect the capacity of the sand making machine. The operator's insufficient understanding of the performance and operating requirements of the equipment, or failure to adjust parameters according to the actual situation, may lead to a reduction in the working efficiency of the sand making machine.
(5) . Lack of motivation:
The sand making machine needs enough power to drive the crushing action. If the power is insufficient, it will also lead to a decrease in capacity. For example, insufficient motor power or low efficiency of the transmission system will affect the power source of the sand making machine.
2. Measures to improve sand production rate of sand making machine
In terms of materials: The hardness, toughness, humidity, viscosity and other properties of the materials will affect the capacity of the sand making machine. Different materials have different physical properties, so it is necessary to select the appropriate sand making machine model and parameter settings according to the characteristics of the materials. At the same time, try to choose materials with moderate hardness for sand making to avoid affecting the normal operation of the sand making machine due to too high or too low hardness of the material.
Equipment: The internal structure, parts materials, lubrication system, etc. of the sand making machine will all affect its capacity. In order to improve the sand production rate of the sand making machine, the following measures can be taken:
(1) . Regularly check the wear and tear of internal parts: After the internal parts of the sand making machine are worn, they must be replaced in time, otherwise, it will delay production and affect the sand production efficiency of the sand making machine. At the same time, it is necessary to strengthen the maintenance and upkeep of the equipment and check the equipment regularly. The operating status and wear and tear of parts can be used to detect and solve problems in a timely manner.
(2) . Regularly check the tightness of the motor V-belt: On the one hand, the sand production efficiency of the sand making machine is also affected by power transmission, and the main factor that affects power transmission is the tightness of the V-belt. Therefore, we should pay attention to the tightness of the power transmission belt and make daily adjustments to ensure that production efficiency is not affected.
(3) . Check the impeller speed: When the impeller speed of the sand making machine is too low, it will lead to insufficient throwing speed, insufficient collision or impact force between the material and the guard plate, and the sand production rate will be greatly reduced, so it is particularly important to ensure that the speed is within the normal range.
(4) . The sealing operation must be done well: The sealing parts of the sand making machine will gradually wear out when the sand making machine is operated for a long time. If the dust is not adjusted for a long time, it is easy to enter the bearings or oil passages, causing the lubrication of the sand making machine to lose its effect. As a result, the bearings will wear out. It will accelerate and the service life will be reduced, so the sealing condition must be maintained regularly.
(5) . Pay attention to strengthening the shock absorption work: Excessive vibration will not only directly affect the operating status of the sand making machine and its components, but will even reduce the service life of the sand making machine, so the shock absorption work must also be done well.
(6) . Operate according to the oil temperature warning: Because the too high oil temperature of the sand making machine means serious bearing heating, it is necessary to stop the machine for inspection in time, and then continue production after troubleshooting.
Operation: Improper operation and lack of standardized operation will also affect the capacity of the sand making machine. In order to improve the sand production rate of the sand making machine, it is necessary to strictly follow the equipment instructions to avoid illegal operations and misoperations. At the same time, professional training for operators to improve their skills and operating levels will help improve the sand production rate of the sand making machine. Through training, operators can better understand the performance of the equipment, operating requirements and how to deal with common problems, etc., so as to better operate and maintain the sand making machine, improve the sand production rate and ensure the normal operation of the equipment.
Design aspect: The design of the sand making machine also has an important impact on its capacity. In order to improve the sand production rate of the sand making machine, the structural design of the sand making machine can be optimized to improve its crushing efficiency and passing capacity. At the same time, it is necessary to consider the applicable scope and market demand of the sand making machine, and select the appropriate model and parameter settings according to the characteristics and needs of different materials.
To sum up, the low capacity of the sand making machine may be caused by many reasons. In order to improve the sand production rate of the sand making machine, it is necessary to start from many aspects, including material selection, equipment maintenance, operating specifications, design optimization, etc. At the same time, it is also necessary to strengthen personnel training and other measures to improve the efficiency of the sand making machine.

In mining, crushing equipment has a wide range of applications and plays an important role in the processing and handling of various ores. By crushing different types of ores, the needs of various major industrial fields can be met. Different types of ores require different crushing processes and equipment. Therefore, it is necessary to comprehensively consider factors such as process requirements, equipment parameters, and quality requirements according to the actual situation to select appropriate crushing equipment. Crushing equipment can be divided into three types: stationary, mobile and semi-mobile crusher. This article will elaborate on these three types of crushing equipment and analyze their differences.
1. Stationary crushing equipment:
Stationary crushing equipment requires the construction of a foundation, with large civil and labor investments. These infrastructures are usually designed and constructed based on the size, weight, and production capacity of the equipment. The requirements for site selection are relatively high, and the site needs to be fully utilized. Once the site needs to be moved to another location, the original infrastructure usually needs to be dismantled and rebuilt.
Stationary crushing equipment is usually used together with feeders, crushers, vibrating screens, conveyors and other equipment to form a production line to form a complete production system. Such a production line can be configured and adjusted according to specific material crushing requirements and process flow. To achieve efficient crushing and screening operations.
2. Mobile crushing plant:
Mobile crushing plant is divided into tire-type mobile crushing plant and crawler-type mobile crushing plant. The tire-type mobile crushing plant relies on the front of a semi-trailer for traction, while the crawler-type mobile crushing plant adopts a self-driven mode, which can realize on-site steering and can be driven to a destination through wireless remote control. on a trailer for quick transitions. The mobile crushing plant does not require the construction of a factory building or civil foundation, which reduces the investment and time of project construction. It also avoids material transfer and reduces transportation costs, and the construction period is short.
The mobile crushing plant breaks through the limitations of site, environment, basic configuration and logistics. It can operate independently as a single unit and can be combined with different models to form a powerful crushing operation assembly line to complete processing operations with multiple needs and improve overall work efficiency. The mobile crushing plant can configure jaw crusher series, cone crusher series, impact crusher series, sand making machine and other crushers according to the customer's material type and product requirements in the process, providing more flexible process configurations to meet users' mobile crushing, mobile screening and other various needs.
3. Semi-mobile crushing plant:
The semi-mobile crushing plant itself does not have the function of traveling and needs to rely on external equipment, such as trailers or cranes, so it can be relocated and transferred quickly. The semi-mobile crushing plant does not require tedious civil construction work, thus saving a lot of time and cost, shortening the project cycle and improving overall efficiency.
The semi-mobile crushing plant is a multi-dimensional integrated frame structure solution composed of one or several crushing and screening unit modules. It is a semi-mobile frame structure mobile crushing plant mainly used in the primary and secondary crushing and screening stages of medium and soft hard rocks, construction waste, concrete blocks and other raw materials. It can be widely used in urban construction waste treatment, mining and tunnel construction rock crushing.
4. The difference between feed size and capacity
5. Equipment purchase suggestions:
Determine usage scenarios and needs: Consider factors such as the type of materials that need to be processed, processing volume, working hours, production requirements and budget.
Define equipment specifications: Understand the parameter information of the equipment, including motor power, speed, number of strokes, and parameters such as rotor diameter, speed, and crushing cavity type of the crusher, and determine appropriate equipment specifications and processing capabilities.
Consider mobility requirements: If frequent transfers or temporary work are required, choose a mobile crushing plant or semi-mobile crushing plant; If long-term stable operation is required, choose stationary crushing equipment.
Understand the manufacturer and service: Understand the manufacturer's reputation and after-sales service. A good manufacturer should provide comprehensive technical support and after-sales service to ensure the normal operation and maintenance of the equipment.
Consider cost-effectiveness: Comprehensively consider factors such as equipment price, operating costs, maintenance costs, and service life to ensure that the equipment can achieve a win-win cost-effectiveness in the long term.
When selecting the type of crushing equipment, factors such as material type, production needs, budget constraints, frequency of site transfers, and the cost and workload of infrastructure construction and dismantling need to be considered. If you still don't know how to choose equipment, you can consult Vanguard Machinery's engineers. The engineers will tailor a plan for you to help you make a reasonable selection.
