Sand Making Machine

Hydraulic Open-box Sand Making Machine

The hydraulic open-box sand making machine is a critical piece of equipment for stone crushing and efficient sand production, particularly suited for materials with compressive strengths not exceeding 350 MPa. The Runxin Machinery hydraulic open-box sand making machine boasts robust crushing capabilities, high-efficiency sand production, and diverse specifications. It can accommodate a maximum feed side length of 350 mm and achieve a production capacity of 50-65 tons per hour. Its versatile crushing performance meets a wide range of requirements and finds extensive application in quarries, railway construction, and other industries. 

Feed size: ≤ 120-190 mm

Discharge size:≤ 5 mm

Power: 11-220 kw

Productive capacity: 20-300 t/h

Weight: 1.5-38 t

Description

The Hydraulic Opening Sand Making Machine is an advanced crushing device designed for efficient production of high-quality artificial sand and fine aggregates. Featuring a hydraulic-driven opening system, it allows quick and safe access to the crushing chamber for maintenance and part replacement. Ideal for processing hard and abrasive materials like granite, basalt, and river pebbles, this machine ensures high output, uniform grain shape, and low operational costs, making it a top choice for construction, mining, and infrastructure projects.

Features

Hydraulic Opening System

Simplifies maintenance and reduces downtime.

High Efficiency

Optimized rotor design ensures maximum crushing capacity.

Adjustable Output

Precise hydraulic control over particle size (0–5mm to 10–30mm).

Durability

Reinforced wear-resistant plates and alloy components extend service life.

Working Principle

Hydraulic Open-box Sand Making Machine
1. Material Feeding: Raw materials enter the crushing chamber via a vibrating feeder. 2. High-Speed Rotor: A motor-driven rotor accelerates materials toward the impact plates. 3. Crushing & Shaping**: Particles are repeatedly struck by the rotor and impact plates, breaking them into finer grains. 4. Hydraulic Adjustment: The hydraulic system adjusts the gap between impact plates to control output size. 5. Easy Maintenance: Hydraulic cylinders open the machine’s upper casing for quick access to internal components. 6. Discharge: Finished products exit through the bottom outlet, while oversized materials are recirculated.
