Jayant RO-TAP Sieve Shaker Model J-94 – Heavy Duty Floor Model Particle Size Analysis System
The JAYANT Model J-94 RO-TAP Sieve Shaker is a precision-engineered heavy-duty laboratory instrument designed for accurate particle size analysis, dry sieving applications, and industrial quality control testing. Built for research laboratories, cement industries, mining operations, aggregate testing facilities, powder processing plants, pharmaceutical industries, and material testing laboratories, this advanced sieve shaker provides highly reproducible and consistent sieving performance for demanding laboratory environments.
Utilizing a unique two-dimensional sieving mechanism, the J-94 combines horizontal circular oscillation with vertical tapping motion to ensure efficient material stratification and superior particle separation accuracy. This dual-action motion simulates highly controlled hand sieving while delivering repeatable analytical results essential for scientific testing and industrial quality assurance applications.
The RO-TAP mechanism is specifically developed for precise dry sieving of particles ranging from 25 mm down to 25 microns. Its advanced tapping and oscillation system enables particles to orient themselves efficiently and pass through critical sieve openings, improving test accuracy and reducing analysis time for fine powders, granular materials, aggregates, minerals, cement, soils, chemicals, and industrial raw materials.
Constructed with a rugged industrial-grade framework, the Model J-94 is powered by an integrated 1/4 H.P. electric motor designed for continuous heavy-duty operation. The machine accommodates up to 8 standard test sieves of 200 mm diameter and 50 mm height, making it suitable for high-volume laboratory testing workflows.
The internal drive system operates within specially lubricated machine oil to ensure smooth mechanical operation, reduced wear, and long operational life under intensive laboratory conditions. With controlled oscillation frequencies of 300–350 horizontal oscillations per minute and 180–200 tapping motions per minute, the J-94 ensures highly efficient particle classification and dependable repeatability.
Widely used as professional laboratory testing equipment for particle grading, sieve analysis, industrial quality control, and research laboratory applications, the Jayant RO-TAP Sieve Shaker Model J-94 offers an ideal combination of mechanical durability, analytical precision, and long-term operational reliability for modern scientific and industrial laboratories.
