Diesel engine–driven vibrating screens have become an essential solution for small and medium-scale sand, gravel, and aggregate producers who require flexible, mobile, and power-independent screening equipment. UNIQUEMAC’s newly upgraded diesel vibrating screen is engineered to deliver high screening efficiency, strong mobility, and durable structural performance — making it a leading choice in Southeast Asia, Africa, and other developing markets.

This article provides a complete technical analysis of the machine’s specifications, materials, structure, working mechanism, industry applications, and advantages.

What Is a Diesel Vibrating Screen?

A diesel vibrating screen is a screening machine powered by a diesel engine instead of an electric motor. It is designed for operations where electricity is limited or unavailable, such as remote quarries, field mines, and mobile crushing sites.
Through circular vibration generated by an inertial exciter, the machine separates materials into different particle sizes for aggregate classification.

Key Specifications of the UNIQUEMAC Diesel Vibrating Screen

The UNIQUEMAC diesel vibrating screen is based on the classic 3YK1225 three-layer vibrating screen, upgraded to enhance practicality, durability, and mobility.

Core Technical Parameters

This optimized configuration ensures stable vibration, uniform material distribution, and high screening penetration across a wide range of material types.

Working Principle: Inertial Exciter and Circular Vibration

The equipment uses a single-shaft inertial exciter system, a design widely adopted in mining-grade vibrating screens.

How It Works

1. The diesel engine drives the main shaft through a belt or coupling.

2. The eccentric mass attached to the shaft rotates.

3. Rotation generates centrifugal inertial force, forcing the screen box to perform circular motion.

4. Materials bounce and move forward on the inclined screen surface.

5. Particles pass through the screen mesh according to size, achieving efficient classification.

This mechanism prevents material clogging and provides sufficient dynamic force for handling wet, sticky, or unevenly sized materials — a common challenge in small-scale aggregate production.

Material Strength and Durability Advantages

UNIQUEMAC prioritizes structural reliability by using high-strength manganese steel for the core screen components.

Material-Related Benefits

• Excellent impact resistance for large and hard rock fragments

• High wear resistance, extending service life

• Lower maintenance cost compared with standard carbon-steel screens

Additionally, the machine can be equipped with rubber springs to replace metal springs if required:

Advantages of Rubber Springs

• Lower noise during operation

• Better vibration absorption

• Reduced stress on the screen frame

• Improved operating stability on uneven ground

These design choices ensure long-term durability in harsh mining and construction environments.

Structural Options: 2 Layer vs. 3 Layer

UNIQUEMAC offers two structural configurations to meet diverse screening needs:

2-Layer Structure

• Suitable for basic material separation or impurity removal

• Ideal for sand, gravel, soil, and light construction material screening

3-Layer Structure

• Enables multi-size screening in a single operation

• Suitable for mining, building materials, chemical raw materials, recycling, and transportation industries

This flexibility allows customers to choose a model based on their target output and material type.

Three Core Advantages of the UNIQUEMAC Diesel Vibrating Screen

1. Strong and Efficient Power Output

The 5.4 HP diesel engine provides consistent torque and excellent driving capacity, enabling continuous screening even with heavy or wet material loads.

2. Fully Independent Operation

No external power supply is required.
This makes the machine perfect for:

• remote quarries

• mountain mining sites

• temporary road construction projects

• mobile crushing and screening setups

Operators can carry out screening anywhere, anytime.

3. Wide Material Adaptability

The machine can efficiently screen:

• river sand

• crushed stone

• granite and basalt aggregates

• construction waste

• mineral ores

• chemical and industrial raw materials

With adjustable capacity and selectable screen layers, it adapts to multi-industry usage scenarios.

FAQ: 

1. Can the diesel vibrating screen operate without electricity?

Yes. It is fully powered by a diesel engine and requires no external electrical supply.

2. What types of materials can it screen?

Sand, gravel, crushed stone, ore, soil, construction waste, coal, chemical raw materials, and more.

3. What is the fuel consumption of the machine?

Consumption varies by material load but remains economical due to the small engine size and efficient transmission system.

4. Is maintenance complicated?

No. Routine checks include engine oil, belt tension, lubrication points, and screen mesh condition — all simple and accessible.

5. Is it suitable for mobile crushing plants?

Yes. Its low weight (2.5 tons) and compact structure make it an ideal companion for mobile crushers.
