High Cost Effective Double Roller Crusher for Glass Bottle Scrap River Pebble Granite Basalt Iron Quartz Stone Copper Gold Silver Ore Crushing Grinding Machine

Product Description

Product Overview

A roller crusher is a traditional crushing equipment that uses two rollers rotating in opposite directions to squeeze and crush materials. With its advantages of simple structure and low over crushing rate, it is still widely used in industrial sectors such as mining, building materials, and metallurgy worldwide. This equipment is suitable for medium and fine crushing of hard, medium hard, and soft solid materials with compressive strength ≤ 250MPa and moisture content < 35%. The feeding particle size is large and the discharging particle size is adjustable, making it an ideal choice in the field of fine crushing.

working principle

The roller crusher drives two rollers to rotate in opposite directions through a motor, reducer, and universal joint. The material falls between two rollers from the feeding port and is rolled into the crushing chamber by the frictional force on the roller surface, and is crushed by the stress mainly caused by compression. The crushed material is naturally discharged downwards under its own weight. By adjusting the gap between the two rollers, the particle size of the discharged material can be precisely controlled.

When encountering hard or unbreakable objects (such as iron blocks) entering the crushing chamber, the movable rollers can automatically retreat under the action of hydraulic cylinders or strong springs, instantly increasing the gap between the rollers and smoothly discharging foreign objects, effectively protecting the equipment from damage and ensuring safe operation.

Product performance and advantages

(1) Low crushing rate and uniform particle size of the discharged material

The roller crusher adopts extrusion crushing method, non impact crushing, produces very little powder, and the finished particles are uniform with low needle like content. For the coal industry, using this machine to crush raw coal only requires iron and impurities removal, without the need for gangue removal. The crushed material has uniform particle size, greatly simplifying the coal preparation process and reducing investment and production costs.

(2) High crushing ratio and efficiency

The crushing ratio can reach 5-8, with a compact structure, small volume, and light weight, which can significantly save investment for systems with the same production capacity requirements. Equipping a roller crusher in the grinding system can increase the production capacity of subsequent grinding equipment by 30% -40% and reduce total energy consumption by 20% -30%.

(3) Overload protection is sensitive, safe and reliable

Equipped with spring or hydraulic overload protection device, the roller can automatically retract when encountering hard or unbreakable objects, protecting the core components from damage and ensuring safe and stable operation.

(4) The roller surface is wear-resistant and has a long service life

 

The grinding roller is made of high-strength wear-resistant alloy material, and the wear-resistant lining plate has a long service life. When the wear is severe, only the lining plate needs to be replaced to restore performance. The maintenance amount is small, the cost is low, and the continuous service life of the equipment can reach more than one year.

 

(5) Good sealing performance, environmentally friendly and low-noise

 

The interior is equipped with dust-proof plates and a sealed crushing chamber design, effectively preventing material splashing and dust overflow. The working noise is low and meets environmental protection requirements.

 

(6) Adjustable discharge particle size and strong adaptability

 

By adjusting the gap between the two rollers, the discharge particle size can be flexibly controlled to meet different working conditions and finished product requirements.

Company Main Products

Q: What is the price of the plastic recycling line?

A: Our pricing is uniquely crafted to fit your distinct requirements. It varies based on the cleanliness level desired in your final product, as well as the production capacity you aim to achieve. Allow us to tailor an optimal recycling line setup that maximizes efficiency while staying within your financial plan.

Q: Is it necessary to have the label removal machine?
A: Utilizing a label removal machine might not be necessary if your bottles do not possess labels or caps, or if label removal is not a crucial step in your processing requirements.

Q: What percentage of labels can the label removal machine eliminate?
A: Our state-of-the-art machine proficiently removes an impressive 96% of labels and caps from compressed bottles, and an even more remarkable 98% from those that are uncompressed, guaranteeing exceptional cleaning performance.

Q: How regularly should the crusher's blade be sharpened?
A: To ensure peak performance and efficiency, it's recommended that the blades be sharpened minimally once every week.

Q: How is dirt and sewage expelled from the high-speed friction cleaning machine?
A: The design of our machine allows for highly efficient discharge of dirt and sewage. This is achieved through a strategically located outlet beneath the machine, ensuring a flawless and smooth cleaning operation.

Q: What's the ideal temperature for hot cleaning in a steamer?
A: To achieve optimal cleaning results, maintain the steamer at an approximate temperature of 80°C, ensuring maximum effectiveness.

Q: How to eliminate left-over labels and caps post-label removal machine?
A: The eradication of any residual labels and caps can be achieved using supplementary rinsing tanks along with vertical label and cap removal machinery, ensuring complete cleanliness.

Q: What is the rinse tank's role?
A: The rinse tank serves a vital function in the cleaning process of crushed materials. It efficiently allows residual label papers and bottle caps to float away, preventing their passage to further processing stages.

Q: What moisture level remains after the material passes through the dehydrator?
A: Our advanced dehydrator reduces the moisture content significantly, achieving a level of ≤3%, ensuring the material is optimally dry.

Q: Can a plastic granulator be attached to the plastic recycling line?
A: Yes, a plastic granulator can be seamlessly integrated with the recycling line, greatly enhancing the overall process efficiency.
