benchtop pulverizer with automatic feeder and vacuum cleaner

Benchtop Pulverizer

The benchtop pulverizer meets the requirements of GB474 “Method of Preparation of Coal Samples” and other relevant standards, providing high-precision pulverized samples for experiments and testing, with strong practicality and reliability.

Features

1. Fully sealed benchtop design: prevents dust leakage, aligns with environmental requirements, and protects both operators and the environment from pollution.
2. High-strength grinding sample disk: integrated dynamic balance, made from special hardened materials for enhanced wear resistance and service life, ensuring stable crushing effect.
3. Special screen design: crafted from special materials and processed with advanced technology for high screening precision and reduced powder residue.
4. Spiral feeder: enables continuous and automatic material supply for uniform feeding, enhancing speed and efficiency of sample preparation.
5. Safety design: automatic power-off when the door is opened, ensuring safe operation and compliance with safety production standards.
6. High-efficiency dust-absorbing device: effectively adsorbs dust and prevents leakage, maintaining a clean experimental environment and operator health.
7. Low noise, smooth operation: runs quietly and smoothly, suitable for long-term continuous use and providing a quiet working environment.

Advantages

1. Strong environmental protection: sealed structure and dust suction device prevent dust leakage, reduce air pollution, and meet modern environmental protection needs.
2. High efficiency and speed: spiral feeder supports automatic, continuous feeding, ensuring efficient sample preparation, ideal for large-scale tasks.
3. Safe and reliable: automatic power-off feature protects operators and avoids accidents, aligning with safety standards.
4. High quality and durability: hardened grinding disk and screen offer wear resistance and long life, reducing replacement costs.
5. Stable operation: smooth, low-noise operation suitable for prolonged, uninterrupted use without disturbing the work environment.

Working Principle

Material is fed automatically via a screw feeder into the crushing chamber, where it’s evenly distributed onto a hardened grinding disk. Under high-speed rotation, constant collision and friction between the material and disk gradually pulverize the sample. The crushed material is screened to meet particle size standards, while a dust-absorbing device keeps the environment clean. An automatic power-off system ensures operator safety when the door is opened.

Application Areas

1. Coal industry: for preparing and crushing coal samples, compliant with national standards, supporting coal quality analysis and testing.
2. Electric power industry: analysis and testing of fuel samples (coal, oil, etc.) for power companies, aiding in fuel quality and performance assessment.
3. Iron and steel metallurgy: crushing ore and iron ore samples for reliable data in ore analysis and quality testing.
4. Geology and building materials: pulverizing rock, mineral, and related samples to support experimental analysis and quality control.
5. Third-party testing: widely used in physical and chemical analysis of solids (coal, ores, etc.), providing fast and efficient sample preparation for testing organizations.
