Construction waste recycling has become an indispensable part of green construction, as it can transform waste such as concrete blocks, bricks, and steel bars into reusable building materials, reducing environmental pollution and resource waste. The construction waste crusher plant is the core equipment in this process, responsible for crushing and processing various construction waste into qualified aggregates. However, construction waste has complex components, irregular shapes, and often contains hard impurities, which easily cause wear, impact, or failure of the crusher plant. Preventing damage to the construction waste crusher plant is crucial to ensuring the continuity of the recycling process, reducing maintenance costs, and improving production efficiency. This article will elaborate on practical measures to prevent damage to the construction waste crusher plant during construction waste recycling , providing targeted guidance for equipment operators and project managers.​

Strict Preprocessing of Construction Waste: Reduce the Burden on Crusher Plant​

The complex composition of construction waste is one of the main causes of damage to the construction waste crusher plant . Therefore, strict preprocessing of construction waste before it enters the crusher plant is the first line of defense to prevent equipment damage. Preprocessing mainly includes sorting, screening, and removing impurities, which can effectively separate materials that are harmful to the crusher plant. First, sort the construction waste by type and size. Use manual sorting or mechanical sorting equipment to separate concrete blocks, bricks, wood, plastic, and metal materials. Wood, plastic, and other flexible materials are easy to wind around the rotating parts of the crusher plant, causing blockage and motor overload; metal materials such as steel bars are hard and may collide with the crusher's hammer head, lining plate, and other components, leading to deformation or wear. Separating these materials in advance can avoid direct contact with the crusher plant.
Secondly, screen the construction waste to control the particle size of the feed. Each type of construction waste crusher plant has a specified maximum feed particle size. If oversized materials enter the crusher, they will cause excessive load on the equipment, block the feed port, or even damage the crushing cavity. Use a vibrating screen or grid to screen the construction waste, and crush the oversized materials separately or cut them into small pieces to meet the feed requirements. In addition, remove hard impurities such as stones, glass, and concrete residues with high hardness from the construction waste. These impurities have extremely strong abrasiveness, which will accelerate the wear of the crusher's hammer head, lining plate, and other vulnerable parts, reducing the service life of the equipment. For example, when processing concrete waste, use magnetic separators to remove steel bars and other metal impurities, and use manual picking to remove large stones and glass pieces.

Standardize Operation of Crusher Plant: Avoid Human-Made Damage​

Improper operation is an important cause of damage to the construction waste crusher plant. Standardizing the operation process and improving the professional quality of operators can effectively avoid human-made damage and ensure the stable operation of the equipment. First, conduct systematic training for operators before they take up their posts. Operators must be familiar with the structure, working principle, performance parameters, and operation procedures of the construction waste crusher plant, and master the correct start-up, shutdown, and adjustment methods. They should also understand the causes and handling methods of common faults to avoid misoperation when problems occur.
During the operation process, strictly follow the start-up and shutdown procedures. Before starting the construction waste crusher plant, check the tightness of the connecting bolts, the lubrication of the bearings, the integrity of the safety protection devices, and the cleanliness of the feed port and discharge port. Start the equipment in the order of "auxiliary equipment first, main equipment later" to ensure that each part is in normal working condition before feeding. When shutting down, stop feeding first, and wait for all materials in the crushing cavity to be processed before shutting down the main motor to avoid material accumulation in the cavity, which will cause difficulty in starting next time. In addition, control the feeding speed reasonably. Feeding too fast will cause the crusher plant to be overloaded, the motor current to exceed the rated value, and even burn the motor; Feeding too slow will reduce production efficiency and cause uneven wear of the equipment components. Use a quantitative feeder to control the feeding amount, ensuring that the equipment works under the rated load.

Strengthen Daily Maintenance and Lubrication: Extend Equipment Service Life​

Daily maintenance and lubrication are the key to preventing damage to the construction waste crusher plant and extending its service life. The construction waste crusher plant works in a harsh environment with high dust, strong vibration, and heavy load, so the wear and tear of components is relatively fast. Timely maintenance and lubrication can reduce the friction between components, prevent corrosion and wear, and ensure the normal operation of the equipment. First, establish a comprehensive daily maintenance system. Formulate a detailed maintenance plan, including daily inspection, weekly maintenance, monthly maintenance, and annual overhaul, and assign special personnel to be responsible for the implementation and recording.
Daily inspection focuses on checking the wear of vulnerable parts such as the hammer head, lining plate, and screen of the construction waste crusher plant. If the wear is serious, replace them in time to avoid affecting the crushing effect and damaging other components. Check the tightness of the connecting bolts and nuts, and reinforce them if they are loose to prevent vibration from causing further loosening or even falling off. Check the lubrication system, including the oil level, oil quality, and oil leakage of the lubricating oil. If the oil level is too low, add lubricating oil in time; If the oil quality is deteriorated, replace it with new oil immediately. The lubricating oil should be selected according to the working conditions of the equipment, and it is not allowed to mix different types of lubricating oil.

Optimize Working Environment: Reduce Environmental Impact on Equipment​

The working environment of the construction waste crusher plant has a significant impact on its service life. Optimizing the working environment can reduce the damage caused by environmental factors and ensure the stable operation of the equipment. First, choose a suitable installation site. The installation site of the construction waste crusher plant should be flat, solid, and well-drained. The ground should be reinforced with concrete to bear the weight and vibration of the equipment, avoiding uneven settlement of the ground, which will cause deformation of the equipment frame and affect the coaxiality of the rotating parts. At the same time, the site should be far away from residential areas and sensitive environmental areas to reduce the impact of noise and dust on the surrounding environment, and also avoid the equipment being affected by external interference.
Take effective dust control measures. During the construction waste recycling process, a large amount of dust will be generated, which will not only pollute the environment but also enter the internal components of the crusher plant, such as bearings, gears, and motors, accelerating wear and causing failure. Install dust removal equipment, such as bag filters and spray dust removal systems, to reduce the dust concentration in the working environment. Seal the feed port, discharge port, and other parts of the equipment to prevent dust from escaping. Operators should wear protective equipment, such as dust masks and goggles, to protect their health and also reduce the impact of dust on the equipment.

Establish Fault Early Warning and Emergency Handling Mechanism: Timely Eliminate Hidden Dangers​

Establishing a fault early warning and emergency handling mechanism can find potential hidden dangers in time and avoid small faults from developing into major damage. First, install monitoring equipment on the construction waste crusher plant to perform real-time monitoring of key parameters, such as motor current, bearing temperature, vibration amplitude, and oil pressure. Use intelligent monitoring systems to collect and analyze this data. When the parameters exceed the normal range, the system will automatically alarm, reminding operators to check and handle the equipment in time. For example, if the bearing temperature is too high, it may indicate insufficient lubrication or bearing wear, and operators can take measures such as adding lubricating oil or replacing the bearing to avoid bearing burnout.
