Vibration-400 Sieving Machine

Updated: 2026-09-16

Overview

The Vibration-400 Sieving Machine is a mid-range industrial vibrating screen designed for precise particle separation across multiple industries. With a 400mm sieve diameter, it balances processing capacity with footprint efficiency, making it suitable for both laboratory and small-scale production environments. The machine's standardized design follows industry norms for sieving equipment, ensuring compatibility with common mesh sizes and auxiliary systems. Its versatility allows adaptation to diverse materials including powders, granules, and suspensions.

Structure and Working Principle

The machine comprises a base unit with vibration motor, sieve stacking mechanism, and optional dust cover. The vibration generator creates three-dimensional motion that propels material across stainless steel or brass test sieves. Material separation occurs through precise vibrational energy transfer - larger particles remain on upper sieves while finer materials pass through sequentially arranged mesh screens. The adjustable eccentric block system allows operators to control amplitude from 0.5-5mm based on material characteristics.

Key Features

The Vibration-400 distinguishes itself through its balanced vibration parameters, achieving 98%+ sieving efficiency for most dry materials. The spring-mounted base reduces noise to <75dB while minimizing vibration transfer to supporting structures. Notable engineering features include quick-release clamp systems for rapid sieve changing, timer-controlled operation (1-99 minutes), and optional digital amplitude display. The powder-coated frame resists corrosion in humid environments common in pharmaceutical and food processing applications.

Application Areas

In pharmaceutical manufacturing, the Vibration-400 ensures API particle size distribution compliance with pharmacopeia standards. Chemical plants utilize it for catalyst screening and raw material quality control. The food industry employs this model for flour grading, spice processing, and additive quality assurance. Mining and metallurgy applications include mineral fraction analysis and abrasives classification, where its durable construction withstands abrasive materials.

Maintenance and Precautions

Routine maintenance involves daily inspection of sieve mesh integrity and monthly bearing lubrication with high-temperature grease. The vibration motor requires annual professional servicing to maintain optimal performance. Critical precautions include avoiding liquid materials without proper splash guards and never operating with damaged screens. Always disconnect power before sieve changes. For abrasive materials, consider installing protective polyurethane screen frames to extend service life.

B2B Procurement Guide

Industrial buyers should verify CE/ISO certification and motor warranty terms (typically 1-2 years). Request test reports showing actual sieving efficiency for your specific material type. For bulk purchases (5+ units), negotiate spare parts packages including extra screens, rubber balls for mesh cleaning, and vibration motor seals. Consider OEMs offering customized solutions like integrated weighing systems or explosion-proof versions for hazardous environments.
