Shengbang Machinery today shares the selection guide for granite sand making machines and maintenance knowledge for crushing equipment. The content focuses on practicality and is suitable for industry novices and practitioners to learn initially. Granite has a uniform structure, hard texture, beautiful color, and durability. It is a high-quality building stone and is known as the “king of rocks”. Granite can be used from roofs to floors in construction. If it is crushed, it can also be made into cement or rock filling dams. Granite is not easy to weather, has beautiful colors, and its appearance color can be maintained for more than a hundred years. In addition to being used as high-end building decoration and hall floors, it is also the material of choice for open-air carving. Because granite is rarer than ceramics or other man-made materials, laying granite floors can greatly increase the value of real estate, and natural granite countertops have unique temperature resistance, making them the choice for processing all kinds of plates. Processing technology: Granite processing is divided into four stages: coarse crushing by jaw crusher, medium and fine crushing by impact crusher or cone crusher, and sand making and packaging by sand making machine....

In the crushing process, the raw material characteristics are one of the core factors affecting the product particle size. Its physical and chemical properties will directly change the crushing difficulty, crushing method and particle distribution. Today, Shengbang Machinery will analyze the impact mechanism and response strategies of raw material characteristics on product particle size from six key dimensions. 1. Hardness and compressive strength Influence mechanism The higher the hardness (such as Mohs hardness ≥ 6), the greater the crushing force required for crushing. Under the same equipment parameters, the product particle size is coarser and it is easy to cause equipment wear (such as the wear rate of jaw plate and hammer increases by more than 30%). Low hardness ore (such as fluorite Mohs hardness 4) has low crushing energy consumption and is easy to produce fine particles, but the particle size distribution may be uneven due to insufficient crushing force. Coping strategy 1. Equipment selection to match hardness High hardness ore (such as iron ore): Cone crusher (laminated crushing, large crushing force) is preferred, the discharge port can be set to 15-30mm, and the fine crushing cone crusher can be used to achieve a particle size of ≤10mm. Low...

Ⅰ Introduction Crawler mobile crushing station is a kind of efficient crushing equipment. It adopts hydraulic and other non-powerful methods to drive and control crawler movement, equipment installation and operation. It has higher energy utilization efficiency and can reach any location of the work site in any terrain. It has higher production efficiency and creates greater value for users. Crawler mobile crushing station can reduce the material handling operations and facilitate the coordination of all auxiliary mechanical equipment. Crawler mobile crushing station has a large crushing ratio, and its optimized design can meet the most required technical characteristics of the crusher, with high productivity and uniform finished product particle size. Ⅱ Product Advantages 1. Full process modular design The crawler mobile crushing station adopts a full-process modular architecture, covering 12 major modules such as the crushing host, screening system, power unit, and conveying device. It supports flexible combination of more than 30 models and has a production capacity of 100-500 tons/hour.Various combinations and power types provide accurate and efficient solutions for material crushing and screening. 2. Excellent terrain adaptability and transfer capability The crawler chassis design gives the equipment strong terrain adaptability. Whether it is rugged mountains, muddy wetlands, or...

Ⅰ. Working principles and structural differences between the two 1. Principle structure of cone crusher The material is crushed by the extrusion and grinding between the moving cone and the fixed cone. The material is crushed by multiple extrusion and bending forces in the crushing chamber. It is mainly composed of a frame, a transmission system, a cone part, an adjustment device, etc. The moving cone rotates eccentrically around the main axis. 2. Principle structure of impact crusher The high-speed rotating rotor drives the plate hammer to throw the material to the impact plate for impact crushing. At the same time, impact crushing will also occur between the materials. It is composed of a rotor, an impact plate, a frame, an adjustment device, etc. The rotor speed is high, and the crushing process is more dependent on the impact force.   Ⅱ. Comparison of crushing performance The crushing force of cone crusher is mainly based on extrusion, and the crushing force is uniform, which is suitable for hard rock. The particle size of the crushed product is relatively uniform, cubic, less needle-like, and the energy consumption is relatively low. The operation is stable. The impact crusher is mainly based on...

Shengbang machinery is a large-scale modern mining machinery manufacturer integrating the production of stone crushing equipment. We have various types of crushers: hammer crusher, jaw crusher, impact crusher, cone crusher, crawler crusher, etc., fixed and mobile, and can be operated by diesel or electric motor. Today I will share with you 5 key parameters that are often overlooked when building a stone crushing line (with selection tips) As a key equipment for material pretreatment, the selection of crusher directly affects production efficiency and cost. However, 90% of buyers often only focus on the price of equipment when selecting, but ignore 5 core parameters, which leads to frequent problems in subsequent use. Today, we will deeply analyze the 5 major parameters of crushing ratio, processing capacity, motor power, crushing chamber type, and equipment speed to help you avoid the minefield of selection! 1. Crushing ratio: the core indicator that determines the crushing effect The crushing ratio refers to the ratio of the feed particle size of the crusher to the discharge particle size, which directly reflects the degree of material crushing. For example, if the maximum feed particle size of a crusher is 100mm and the discharge particle size can reach...

Last time we talked about 05Maintenance Cost Analysis, let’s continue the discussion. Multi-cylinder collaborative cost control 1）System complexity The multi-cylinder cone crusher uses multiple hydraulic cylinders to work together. The system structure is complex and requires high accuracy and stability of the control system, which increases the difficulty and cost of maintenance. 2）Difficult trouble shooting Due to the complexity of the multi-cylinder system, once a failure occurs, the troubleshooting and repair process is relatively complicated, requiring professional technicians and advanced testing equipment, which increases the labor costs. 3）Long-term stability Although the multi-cylinder system has high initial investment and maintenance costs, it has high stability and reliability in long-term operation, can effectively reduce equipment failure rate and downtime, and has high economic benefits in the long run. 04 Intelligent maintenance Multi-cylinder systems are usually equipped with intelligent monitoring and diagnostic systems that can monitor the equipment’s operating status in real time, provide early warning of potential failures, and reduce maintenance costs and risks. 06 Factors of Chosen Raw material characteristics matching principle Hardness adaptability Single-cylinder cone crusher is suitable for processing medium-hard materials such as limestone and dolomite because of its uniform crushing force and large throughput; multi-cylinder cone crusher is...
