Introduction to the Features of the Dongguan Claw-Type Crusher

The feeding system of the Dongguan claw-type crusher mainly consists of a feed inlet, a feeding frame, a feeding wheel, and a drive unit. The feeding wheel and the drive unit are responsible for conveying material into the crushing chamber, while the feeding frame serves to secure the material and protect the crusher.

Learn about the Dongguan claw-type crusher in one minute.

The Dongguan claw-type crusher is a mechanical device used for crushing waste materials. As early as the beginning of the 1980s, with China’s markets gradually opening up and construction projects steadily advancing, a group of small machinery manufacturers in Dongguan, Guangdong Province, began continuously developing and improving claw-type crushers, aiming to address the challenges of storing and recycling large volumes of waste materials.

A Brief Discussion on Vibrating Screens—Huichuang Plastics Machinery

As the saying goes, “You can’t judge a book by its cover; you can’t measure seawater with a bucket.” Don’t be fooled by the seemingly unremarkable appearance of this vibrating screen—beneath its simple exterior lies a hidden sophistication. Its straightforward design allows one to intuitively grasp the basic structure of the vibrating screen. Materials enter the screen from the top opening and are set into vibration by two vibrating motors. When these two motors rotate synchronously in opposite directions, the centrifugal forces generated by their eccentric weights cancel each other out along the direction parallel to the motor shafts, while their combined forces add up along the direction perpendicular to the motor shafts. As a result, the vibrating screen’s motion trajectory becomes a straight line. By adjusting the direction of the motor’s rotation, the motion trajectory can be directed either upward or forward, thereby achieving the purpose of grading and separating materials. Advantages: 1. High screening efficiency, suitable for all kinds of powdered and granular materials. 2. The screen mesh is extremely easy to replace, simple to operate, and easy to clean. 3. The mesh openings remain unobstructed, and the sealing performance is excellent, preventing powder from flying around. 4. Impurities and coarse particles are automatically discharged, allowing for continuous operation. 5. The screen frame is available in both wooden and steel versions, enabling users to select the material that best suits their specific needs. 6. Simple structure and convenient maintenance. 7. The screen can be stacked up to six layers, though it’s generally recommended to use no more than three layers. Applicable Industries: Widely used in industries such as chemical, pharmaceutical, food, metal, and metallurgical sectors for screening and classifying powdered and granular materials. Applications include wood chips, wood powder, activated carbon, carbon black, and other fibrous materials, as well as powdered feed ingredients, additives, glass bead powder, alumina, and more.

Solutions to Common Faults in Vibratory Feeders During Operation

Today, Dongguan Huichuang Plastics Machinery Co., Ltd. will briefly explain to you some troubleshooting methods for common faults that may occur during the operation of vibratory feeders: The vibratory feeder is a commonly used piece of mineral processing equipment in sand and gravel production lines, second only to crushers and sand-making machines. Here, Qidong Zhuoya Mining Machinery would like to remind everyone that vibratory feeders, just like any other machinery, inevitably encounter various issues during operation. Today, Zhuoya will share with you how to address these problems. In a vibratory feeder, if the vibration gap between the iron core and the armature of the exciter becomes blocked, the following fault symptoms will appear: During operation, the built-in electromagnetic feeder inside the vibrator may cause the feeder’s power switch to trip. After re-energizing the feeder, you’ll notice the fuse heating up, the current exceeding the rated value, and the fuse blowing within a short period of time. Upon inspecting the feeder’s control system, you’ll find that the contactor engages normally, yet the power switch still trips frequently, and the amplitude of the vibratory feeder when operating is virtually zero. Fault Analysis: Based on the observed symptoms, the primary cause is that material has entered the interior of the exciter, completely blocking the vibration gap. If you open the sealing cover for inspection, you’ll find that the silicone rubber seal has been damaged. Sometimes, damage to the exciter’s cooling hose can also lead to this issue. Leakage from the outer casing of the vibratory feeder: The built-in vibratory feeder in the vibrator has numerous sealing bolts on its housing, making it particularly difficult to ensure a tight seal after disassembly and maintenance. Recommended solution: Generally, tightening the bolts and adjusting the pressure at the discharge point can resolve the issue. Motor-driven vibratory feeder Damaged exciter bearings: During operation, the exciter bearings may start smoking and turn red. This is due to the eccentric weight continuously impacting the bearings as it rotates, combined with poor working conditions on-site, which significantly shortens the bearing’s service life compared to its normal lifespan. Recommended solution: We suggest using high-quality or imported bearings to extend their service life. Additionally, proper lubrication of the bearings is crucial; regular lubrication should be enhanced, or an automatic lubrication system should be installed.
