Introduction
A sieve shaker is a laboratory instrument used to separate and classify particles by size using a stack of sieves with different mesh openings, and it is used for particle size analysis of powders, granular materials, and aggregates in the construction, mining, chemical, pharmaceutical, food, and agricultural industries. In operation, a stack of sieves with decreasing mesh openings is assembled, with the coarsest sieve on top and a collecting pan at the bottom, and a weighed sample is placed on the top sieve; the sieve stack is placed on the shaker, which vibrates, taps, or oscillates the stack for a specified time, causing the particles to pass through the sieves according to their size, and the material retained on each sieve is weighed, and the particle size distribution is calculated and expressed as the percentage of material in each size fraction. Sieve shakers are available in various types, including vibratory shakers, which vibrate the stack in a circular or vertical motion; tapping shakers, which combine vibration with a tapping action; and air-jet sieves for fine powders, and they are used for quality control of powders and aggregates, for particle size analysis in laboratories, for process control, for research, and for compliance with standards, such as ASTM and ISO methods. Features include adjustable shaking time and amplitude, and sieves of various mesh sizes. With their importance in particle size analysis, sieve shakers are essential instruments for particle classification.

FAQ
Q1: What testing scenarios is this shaker mainly applied to?
A: The sieve shaker is used in soil testing, aggregate analysis, food processing, pharmaceutical manufacturing, chemical production, construction, mining and quality control laboratories to perform particle size analysis of powders, granules, soils and aggregates through mechanical sieving for quality control, specification compliance and research. It supports soil particle size distribution for geotechnical engineering, aggregate grading for construction, food powder and granular product quality testing, pharmaceutical powder and granule analysis, chemical product particle size determination, mining and mineral processing, and general particle size analysis. The mechanical shaker provides consistent, reproducible sieving compared with manual sieving, improving accuracy and efficiency. It is essential for soil, aggregate, food, pharmaceutical, chemical, mining and quality control laboratories requiring particle size analysis through mechanical sieving for quality control, specification compliance, process optimization and research, where consistent, reproducible mechanical sieving provides accurate particle size distribution data for material characterization, quality assessment, process control and regulatory compliance in construction, agriculture, food, pharmaceutical, chemical and mining applications requiring reliable particle size analysis using standard test sieves.
Q2: What standards does the shaker comply with?
A: The sieve shaker follows ISO 3310 for test sieves, ASTM E11, ISO 2591-1 for sieving, ASTM D422 for soil, and relevant GB/T standards including GB/T 6003 for test sieves and GB/T 6005 for test sieve shakers. The hardware complies with IEC 61010 laboratory safety standards. Test sieves should be certified and traceable to international standards. Calibration should verify sieve openings and shaker performance.
Q3: What is the warranty period for the whole machine and key components?
A: The whole sieve shaker is covered by a 12-month warranty. The drive mechanism, motor, controller, clamping system and housing are covered, while sieves, belts and fuses are consumables or accessories. Damage from overloading, improper use or unauthorized repair is excluded. Extended service contracts may be available.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires basic training in sieve analysis, sample preparation and shaker operation. We provide an operation manual and remote guidance. Proper sieve stack assembly, sample quantity, shaking time, amplitude setting and result calculation are important for accurate particle size analysis.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Sieve verification with certified reference particles recommended every 6-12 months for critical testing. Shaker amplitude and timing verification periodically. Sieve condition (wear, tears, blockage) checked before each use. Full system maintenance annually. Routine cleaning of sieves after each use.
Q7: Are supporting consumables universal?
A: Test sieves are available from multiple laboratory suppliers, though sieve diameter and standard should match the shaker. Long-term consumable cost depends on sieve usage and replacement frequency.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes sieve diameter, motion type (vibratory, tapping, rotary), amplitude, timer, clamping mechanism and noise level. Additional sieves, covers and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the sieve shaker and accessories with an operation manual. On-site installation and training are not included for standard orders but can be arranged for laboratory setup. Remote guidance is provided.
Q10: What types of samples are compatible with this equipment?
A: The sieve shaker analyzes particle size of dry powders, granules, soils, aggregates and other particulate materials within the sieve range, sample capacity and shaker specification. Wet sieving may be required for fine or cohesive materials. Very large particles require appropriate sieve sizes. Moist samples should be dried before dry sieving unless wet sieving is specified. Users should select appropriate sieve sizes for the expected particle distribution, use proper sample quantity (not overload sieves), set appropriate shaking time and amplitude per the test method, weigh each sieve fraction accurately, clean sieves after each use, and report results as particle size distribution with the test method specified. For quality control, results should be compared with product specifications or standard gradation requirements. Sieves should be inspected regularly for wear, tears and blockage, and replaced when damaged to maintain accurate results.
