Tumbler Screening Machines

Tumbler Screening Machines are available in carbon steel, stainless steel, and special steel to meet diverse operating requirements, such as corrosion resistance, wear resistance, and anti-static properties. Using a rocking motion, these machines classify, remove impurities, separate solids and liquids, and perform particle size analysis on powders and granular materials.

Tumbler Screening Machines excel at handling fine powders and irregular particles that are prone to dusting, require high precision, high density, are prone to adhesion, and carry static electricity, without disrupting the material's shape. With a single machine throughput of 1 kg/h to 50 t/h, they can screen particle sizes ranging from 25 mm to 37 microns (400 mesh) and even finer. These machines are typically configured with one to five screen layers, allowing for simultaneous separation of two to six different product sizes.

Advantages of Using Tumbler Screening Machines

High Adaptability: Suitable for screening chemicals, metal powders, food ingredients, plastic granules, and other materials, whether dry, wet, or containing oil.

Wide Particle Size Range: Capable of processing ultrafine powders (20–200 μm) to coarse particles (10–50 mm), it achieves precise grading from 2 to 6 grades using multiple screens.

High Screening Accuracy: Unique three-dimensional elliptical motion simulates manual screening, extending material residence time on the screen surface, enabling grading, impurity removal, and solid-liquid separation, achieving purities exceeding 95%.

Anti-Clog Design: Tumbler Screening Machines gentle motion reduces screen clogging for materials prone to agglomeration, static electricity, or moisture, making cleaning and maintenance easier.

Durable Material: Available in corrosion-resistant 304 or 316 stainless steel, suitable for acidic, alkaline, or special chemical environments, while also meeting food-grade, pharmaceutical-grade, and explosion-proof requirements.

High Capacity, Low Energy Consumption: High throughput, stable operation, low noise, and low energy consumption make it suitable for continuous production.

Safe and Reliable: Suitable for flammable, explosive, or volatile materials, the design complies with explosion-proof and safety regulations to ensure safe production.

Parameters of Common Tumbler Screening Machines

Tumbler Screening Machines are available in a variety of materials, including stainless steel wire mesh, mild steel wire mesh, polyester mesh, nylon mesh, and specially coated mesh. Screen diameters range widely, from 400mm to over 2000mm, and are customizable. The figure below shows the parameters of common Tumbler Screening Machine models:

Operating Principle of Tumbler Screening Machines

Operating Principle of Tumbler Screening Machines: During operation, a motor, through a specially designed transmission system, drives the screen in an elliptical oscillating motion, mimicking manual screening. The material on the screen first moves in a horizontal circular motion, gradually spreading outward. Then, a slight vertical tossing motion occurs, causing fine particles to pass quickly through the screen and coarse particles to move toward the discharge end. This motion not only loosens the material, preventing clumping and screen blockage, but also prolongs the material's residence time on the screen, improving screening accuracy and efficiency. Throughout this process, the screen remains tensioned, preventing localized wear and further enhancing screening consistency and stability.

Tumbler Screening Machines Applications

Tumbler Screening Machines, with their high precision, high mesh utilization, anti-clogging screens, and dust-proofing, are suitable for virtually all industrial applications requiring sizing, impurity removal, and filtering of dry powder or granular materials.

The food industry screens flour, powdered sugar, starch, yeast, salt, MSG, milk powder, soy milk powder, juice powder, seasonings (pepper, chili powder), tea, dehydrated vegetables, and food additives.

The pharmaceutical and cosmetics industries screen traditional Chinese medicine powders, Western medicine raw material powders, pill granules, health supplement powders, creams, facial mask powders, talc, pearl powder, rouge, eye shadow, and other cosmetic ingredients.

The chemical and plastics industries tumbler screening machines screen resins, pigments, dyes, coatings, powder coatings, PVC powder, additives, fillers, laundry detergents, pesticides, rubber granules, and plastic masterbatches.

The metallurgy and mining industries screen metal powders (iron, aluminum, copper), alloy powders, abrasives (corundum, silicon carbide), quartz sand, kaolin, mica powder, and ore particles.

The ceramics and building materials industries tumbler screening machines screen glazes, ceramic powders, glass powder, graphite powder, cement additives, refractory materials, gypsum powder, and more.

Tumbler screening machines address the pain points of traditional vibrating screens when processing specialized materials, including low efficiency, clogging, high dust generation, and substandard accuracy. Whether you're looking to improve product quality, optimize production processes, or create a cleaner and safer working environment, choosing the right vibrating screen is a worthwhile investment.
