With its high processing efficiency, uniform blasting effect, and compact structure, the LSQZR980 is widely used in industries such as auto parts manufacturing, hardware processing, casting, and forging. It is particularly suitable for processing small workpieces such as bolts, nuts, gears, bearings, and small castings and forgings. This article will provide a detailed introduction to the LSQZR980 Drum Type Shot Blasting Machine, including its structural features, working principle, performance parameters, application scope, operation guidelines, maintenance strategies, and comparative advantages.

The structural design of the LSQZR980 Drum Type Shot Blasting Machine is compact and reasonable, consisting of key components such as the drum body, shot blasting system, shot circulation system, dust removal system, transmission system, electrical control system, and frame. The drum body is the core component of the machine, where the workpiece is tumbled and blasted. It is usually made of high-strength steel plates and lined with wear-resistant rubber or manganese steel plates to withstand the impact and friction of the workpiece and shot particles. The drum body is inclined at a certain angle, which helps to transport the workpiece from the feeding end to the discharging end during rotation. The inner wall of the drum is often equipped with lifting plates, which can lift the workpiece during the rotation of the drum and then drop it, ensuring that the workpiece is fully tumbled and in contact with the shot particles, thus achieving uniform blasting.

The shot blasting system of the LSQZR980 is responsible for generating the shot stream to impact the workpiece surface. The system mainly includes shot blasting wheels, shot storage tanks, and feeding pipes. The machine is usually equipped with one or more high-efficiency shot blasting wheels, which are installed at the appropriate position of the drum body to ensure that the shot particles can be accurately projected into the drum. The shot blasting wheels are composed of impellers, blades, control cages, and drive motors. The impeller rotates at high speed under the drive of the motor, generating centrifugal force to accelerate the shot particles. The blades are made of wear-resistant materials such as high-chromium cast iron, which have excellent wear resistance and can ensure long service life. The control cage is used to adjust the direction and angle of the shot stream, so that the shot particles can cover the entire inner space of the drum, ensuring that each workpiece is uniformly blasted. The shot storage tank is used to store the shot particles, and the feeding pipe transports the shot particles from the storage tank to the shot blasting wheels, ensuring a continuous supply of shot particles.

The shot circulation system of the LSQZR980 is designed to recycle and reuse the shot particles, which is essential for reducing material consumption and improving production efficiency. The system consists of a spiral conveyor, bucket elevator, separator, and return pipe. After the shot particles are projected into the drum and impact the workpiece, they fall into the bottom of the machine together with the impurities such as rust, oxide scale, and debris. The spiral conveyor installed at the bottom of the drum transports the mixture of shot particles and impurities to the bucket elevator. The bucket elevator lifts the mixture to the separator, which separates the qualified shot particles from the impurities. The separator usually adopts a combination of air separation and screening, which can effectively remove the fine impurities and unqualified shot particles (such as broken or worn shot particles). The qualified shot particles are then returned to the shot storage tank through the return pipe for reuse, while the impurities are discharged into the dust removal system for treatment.

The dust removal system of the LSQZR980 is an important part to ensure the environmental protection and operator health. During the shot blasting process, a large amount of dust and debris will be generated, which must be effectively collected and treated. The dust removal system is composed of a dust collector, suction pipe, fan, and exhaust pipe. The fan generates negative pressure, which sucks the dust and debris from the drum body and the separator into the dust collector through the suction pipe. The dust collector adopts filter bag filtration technology, which has high dust collection efficiency. The filter bags can capture the dust particles in the air, and the clean air after filtration is discharged into the atmosphere through the exhaust pipe. The collected dust is stored in the dust hopper of the dust collector, which can be regularly cleaned and disposed of. The dust removal system of the LSQZR980 meets the national environmental protection standards, ensuring that the working environment is clean and free from pollution.

The transmission system of the LSQZR980 is responsible for driving the rotation of the drum body. It is composed of a motor, reducer, chain drive, and supporting roller. The motor provides power, which is transmitted to the reducer to reduce the speed and increase the torque. The reducer drives the drum body to rotate through the chain drive. The supporting roller supports the drum body, ensuring that it rotates smoothly. The rotation speed of the drum body can be adjusted according to the type and requirements of the workpiece. A higher rotation speed can make the workpiece tumble more fully, but it may also increase the wear of the workpiece and the drum. A lower rotation speed may result in insufficient tumbling of the workpiece, affecting the blasting effect. Therefore, the rotation speed of the drum should be reasonably adjusted according to the actual situation to achieve the best processing effect.

The electrical control system of the LSQZR980 is designed to be simple and reliable, realizing the automatic control of the entire machine. The system mainly includes a PLC controller, touch screen, frequency converter, and various sensors. The PLC controller is the core of the control system, which can realize the logic control of the machine's startup, operation, and shutdown. The touch screen provides a friendly human-machine interface, allowing the operator to set parameters such as the rotation speed of the drum, the working time of the shot blasting wheels, and the feeding amount. The operator can also monitor the operation status of the machine through the touch screen, such as the working status of each motor, the level of the shot particles, and the pressure of the dust removal system. The frequency converter is used to adjust the rotation speed of the motor, ensuring the stable operation of the machine and saving energy. In addition, the electrical control system is equipped with multiple safety protection devices, such as overload protection, short-circuit protection, emergency stop button, and safety door interlock. When the machine has an abnormal situation or the safety door is opened, the machine will automatically stop, ensuring the safety of the operator and the machine.

The working principle of the LSQZR980 Drum Type Shot Blasting Machine is relatively simple but efficient. The entire working process can be divided into four stages: feeding, tumbling and blasting, shot recycling, and discharging. First, the operator puts the batch of small and medium-sized workpieces into the drum body through the feeding port. Then, the operator closes the safety door and starts the machine through the electrical control system. The transmission system drives the drum body to rotate, and the lifting plates inside the drum lift the workpieces and then drop them, making the workpieces tumble continuously in the drum. At the same time, the shot blasting wheels start to work, projecting high-speed shot particles into the drum body. The shot particles impact the surface of the tumbling workpieces, removing rust, oxide scale, oil stains, and burrs from the workpiece surface. The impact of the shot particles also can strengthen the workpiece surface, improving its fatigue strength and hardness.

During the tumbling and blasting process, the shot particles that have completed the impact fall into the bottom of the machine together with the impurities. The spiral conveyor transports the mixture of shot particles and impurities to the bucket elevator, which lifts them to the separator. The separator separates the qualified shot particles from the impurities. The qualified shot particles are returned to the shot storage tank and reused in the shot blasting process, while the impurities are sent to the dust removal system for collection and treatment. After the preset blasting time is reached, the machine automatically stops the shot blasting wheels and the transmission system. The operator opens the discharge door of the drum body, and the tumbled workpieces are discharged from the drum under the action of gravity, completing the surface treatment process. The entire working process can be realized automatically, which greatly reduces the labor intensity of the operator and improves the production efficiency.

The LSQZR980 Drum Type Shot Blasting Machine has excellent performance parameters, which ensure its high processing efficiency and good processing effect.
