CATHAY Experimental Double Roller Crusher Double Roller Extrusion Laboratory Material Crushing Particle Size Controllable

CATHAY experimental double-roll crusher: double-roll precision extrusion, ideal for laboratory material crushing

1. Double-roll counter-pressure to achieve uniform material crushing

CATHAY experimental double-roll crusher uses the extrusion force generated by the relative rotation of the double rollers as the core crushing power, and controls the crushing particle size by adjusting the gap between the two rollers. The two rollers of the equipment are driven by a motor and rotate at a constant speed in opposite directions (the speed is adjustable from 30-300r/min). After the material enters the crushing chamber between the two rollers from the feed inlet, it is clamped and squeezed by the rotating rollers. Under the combined action of extrusion force and friction, it is broken into small pieces and finally discharged from the gap between the two rollers. The roller surface adopts different texture designs - toothed rollers are used when processing hard materials (such as ores and ceramics), and the crushing effect is enhanced by combining shearing and extrusion; smooth rollers are used when processing brittle materials (such as glass and coke) to avoid excessive crushing and ensure uniform particle size of the discharge. The crushing gap can be adjusted through a precision screw mechanism, with an adjustment range of 0.1-10mm, and the minimum output particle size can reach 0.1mm, meeting the laboratory's diverse needs for material fineness.

2. Multi-material adaptation, covering multi-field experimental scenarios

Geological ore analysis: In the rock and ore component detection experiment, the ore sample with a diameter of ≤50mm can be crushed into uniform particles (such as 2-5mm), providing homogeneous raw materials for subsequent grinding, screening, and chemical analysis. For example, the crushing of copper ore samples can ensure that the copper element is evenly distributed in the sample, reduce detection errors, and make the analysis results more representative.

Building material performance test: Suitable for the crushing of building material samples such as cement clinker, limestone, and gypsum. In the cement strength experiment, the cement clinker is crushed to a specified particle size and then ground to ensure that the specific surface area of the cement meets the standard and ensures that the strength test data is accurate; the crushing of new building materials (such as aerated concrete and insulation bricks) can study the internal structure and component distribution of the material.

Metallurgical material experiment: used for the crushing and processing of metal ores and alloy waste. In the metal recovery rate experiment, crushing the ore to a suitable particle size can improve the efficiency of subsequent mineral processing experiments; crushing scrap metals (such as aluminum filings and iron filings) is convenient for studying the recycling process of metals. The equipment uses wear-resistant roller surfaces and can withstand the wear of metal materials.

Chemical raw material preparation: For chemical samples such as fertilizers, catalysts, and pigments, they can be crushed into uniform particles for performance testing. In the fertilizer solubility experiment, the crushed fertilizer particles can dissolve quickly, shortening the experimental time; the crushing of solid catalysts can study the relationship between their particle size and catalytic activity. The anti-corrosion roller surface of the equipment (such as 316 stainless steel) can resist the erosion of chemical raw materials.

Soil environment monitoring: used for the crushing of soil and sediment samples, the collected soil blocks are crushed into fine particles (such as ≤2mm), which is convenient for testing indicators such as soil pH, organic matter content, and heavy metal content. There is no material pollution during the crushing process, ensuring that the test results can truly reflect the soil environmental conditions.

3. Performance advantages to ensure efficient and accurate experiments

Precise particle size control: precision ball screw is used to adjust the roller gap, with an adjustment accuracy of up to 0.01mm. With the digital display device, the crushing gap can be accurately set and displayed to ensure the consistency of crushing particle size of different batches of samples. The experimental repeatability error is ≤2%, which meets the requirements of comparative experiments for data stability.

High discharge uniformity: The double rollers adopt a synchronous drive design, with a speed difference of ≤1r/min. The material is evenly stressed in the crushing chamber. The particle size distribution range of the crushed material is narrow, and the proportion of over-coarse or over-fine particles is ≤5%, avoiding experimental deviations caused by uneven discharge of traditional crushing equipment.

Safe and convenient operation: equipped with an ergonomically designed operation panel, the crushing time and roller speed can be set by knob or touch screen, supporting timed crushing (0-60 minutes), and automatically stopping after the set time is reached. The equipment is equipped with an emergency stop button and a protective cover interlocking device. When the protective cover is opened, it will stop immediately to prevent the operator from contacting the rotating parts and ensure the safety of the experiment.

Easy to clean and maintain: The roller can be quickly disassembled, which is convenient for cleaning residual materials and avoiding cross-contamination of different samples; there is a drawer-type material receiving box at the bottom of the crushing chamber, which is convenient for material collection. The material receiving box is made of transparent material, which can visually observe the crushing situation. It is easy to clean after the experiment, suitable for continuous processing of multiple batches of samples.

4. Structural design, taking into account durability and experimental adaptability

Miniature and compact structure: The overall size of the equipment is small (length, width and height are about 500×300×400mm), light weight (about 50kg), can be placed directly on the laboratory table, does not take up too much space, is easy to move and store, and is suitable for the limited working environment of the laboratory.

High-strength crushing parts: The roller is made of high-chromium cast iron (Cr26) or alloy tool steel (Cr12MoV). After quenching, the surface hardness reaches HRC55-60, with excellent wear resistance, and the service life can reach more than 10,000 times (based on crushing medium-hardness materials), which can withstand the wear of long-term experimental use.

Low-noise operation: The roller operation is supported by precision bearings and designed with shock-absorbing pads. The operating noise is less than 65 decibels, which is much lower than the noise level of traditional crushers. It will not interfere with the quiet environment of the laboratory and meets the laboratory noise control standards.

Anti-overload protection: The motor is equipped with an overload protection device. When the crushed material is too hard or too much, causing the load to exceed the rated value, the power supply will be automatically cut off and an alarm will be sounded to avoid motor burnout or roller damage, protect equipment safety, and reduce maintenance costs.
