Types of China gravel machines

A China gravel machine is used to make and process gravel for construction purposes. Various types of gravel machines can crush larger stones into smaller sizes used as gravel. The types of machines are as follows:

• Gravel crushers

  A crusher is an essential part of the gravel-making process. It breaks down larger rocks into smaller ones by applying pressure. There are different kinds of crushers used in the gravel-making process, including jaw, impact, cone, gyratory, and process-specific crushers like hammer mills or sand-makers. Each type of crusher has its unique way of breaking the rock and producing a specific size and shape of gravel.

• Gravel screens

  After the gravel is crushed, it must be sorted into different sizes. That is what a screening machine does. The crushed rocks are moved around on flat surfaces called decks. The smaller pieces fall through holes in the flat surface, and chains or belts move the larger pieces around on top of the deck. Screens can separate materials into two to six different sizes. Screens used for gravel are known as vibratory screens.

• Gravel washers

  Gravel needs to be cleaned to remove sand, clay, dirt, and other minerals. A washing machine cleans gravel. The dirty material is removed through water jets or high-pressure hoses. The water and soap also help remove any contaminants on the gravel. Washing facilities are important for preparing aggregate materials that meet quality standards.

• Gravel conveyors

  A conveyor machine moves different types of materials by using a belt that carries items to different locations. They can be used to carry rocks to stockpiles, processing areas, or loading facilities. Conveyor belts are helpful because they can move a lot of different materials over long distances. They can be made into different sizes and are an important part of how aggregate materials are handled and processed.

These machines work together in quarries and aggregate production facilities to create a steady supply of gravel materials used in various construction and landscaping projects.

Specifications and Maintenance of China Gravel Machine

Specifications of China Gravel Machine

• Capacity: The capacity of a gravel crushing machine is an indicator of how much gravel/rock it can process within a specified timeframe. It is usually quantified in tons per hour (TPH).
• Power: The power of a gravel crushing machine is typically specified in kilowatts (kW) or horsepower (HP) and represents the motor's power that drives the machine.
• Weight: The weight of the gravel crushing machine. It is usually measured in tons or kilograms and indicates the machine's overall weight.
• Size: Overall dimensions include length, width, and height.
• Operating Cost: This includes costs associated with fuel, electricity, lubricants, replacement parts, etc.
• Mobility: If the crusher machine is a mobile or portable type, its mobility will be an important specification. This may include the weight of the machine itself, the size of the tires, and the size of the chassis.

Maintenance of China Gravel Machine

• Regular Cleaning: Regularly clean the surface of the gravel crusher machine to remove dust, waste, etc., to avoid blockage of the cooling system and air intake.
• Lubrication System Maintenance: Regularly check and maintain the lubricating oil and lubricating grease of the gravel machine, ensuring that the lubricating oil is clean and at the appropriate level.
• Screen and Mesh Maintenance: The screening device and meshes are critical components of the gravel machine. Regularly check them for wear and tear, and clean up the greasy dirt and mineral deposits on them.
• Replacement of Parts: The gravel machine will have some parts that are easily worn, such as blades, hoppers, and conveyors. Regularly check these parts for wear or damage and replace them promptly.
• Electrical and Hydraulic Systems: Regularly check the electrical and hydraulic systems of the gravel machine, ensuring that the wires and connectors are firm, and the hydraulic oil is clean and at the proper level.
• Dust Control: The crushing of gravel machines may produce a large amount of dust; therefore, regularly check the dust control systems such as dust collectors and water spray systems, ensuring they work properly.

Usage scenarios for the China gravel machine

Gravel crushing machines have various applications in construction and landscaping. Among some of the most popular usage scenarios of the China gravel machine include the following.

• Gravel parking lots: A China gravel machine is used to crush larger rocks into smaller pieces that form the base material or surface of a parking lot. The crushed gravel gives room for drainage and creates a sturdy surface that can support vehicles.
• Road base and surfacing: Gravel machines produce aggregate for road construction. The machine crushes aggregate is used as a sturdy base for new roads. It can also be used as a paving material for rural roads, highways, and driveways.
• Drainage trenches: The gravel machine can create the gravel layer for drainage trenches. Such trenches allow water to flow freely and prevent flooding in landscapes. Many landscapers use gravel machines to create drainage layers for effective water management.
• Erosion control: The gravel machine helps to control erosion by crushing rocks into smaller pieces and spread them along sloping landscapes. The gravel may prevent soil erosion by water runoff during heavy rainfall.
• Landscaping features: Landscapers use gravel machines to create landscaping features in commercial and residential properties. Landscapers can use the crushed gravel for decorative rock gardens, walking paths, and driveways. Homeowners or property managers can also use the gravel to fill space around planting beds and trees.
• Foundation backfill: Gravel machines can provide the backfill material for foundations of newly constructed buildings. The gravel, which consists of broken stone, offers stability to building foundations, allowing them to settle sturdily on the ground.

How to choose China gravel machines

Buyers need to analyze the selection of China gravel machines based on a few critical factors that affect the decision for suitable purchasing.

• Business requirements analysis

  It is essential to determine the volume of gravel required per day or per hour. Assess the types and sources of raw materials of the buyer's including river sand, stones, limestone, etc. Different kinds of materials need the distinct working principles of machines to process gravel. Analyze the current production line's existing equipment to find out the right type of machine that helps to improve the overall efficiency of production.

• Machine's capabilities

  Buyers need to match the business requirement with the machine's capacity, feeding size, discharging size, and output granularity.

  Apart from that, the features of the machine, such as whether it possesses a noise-reduction mechanism and dust suppression technology, should also be considered more or less.

• Quality and durability

  Buyers need to choose those machines with high-quality and durable core components like motors and bearings. Moreover, they also need to ensure that the machines comply with national standards and have passed relevant certifications.

• Automation and intelligence

  If buyers have the budget, they can consider machines with intelligent control systems that provide remote monitoring and automated production.

• Suppliers' services

  Consider the suppliers' installation and after-sales services. A good supplier always provides the comprehensive services and technical support to the buyer.

China Gravel Machine FAQ
