Counterroll crusher

Description

PG roller crusher is an environmentally friendly crushing equipment with less dust and low noise, which can flexibly adjust the discharge and crushed materials to be cube-shaped and fine discharge particle size. It is widely used in metallurgy, chemical industry, electric power, transportation and other fields, and can be used for medium and fine crushing of medium hard and soft ore. It is suitable for crushing materials with compressive strength ≤160MPa, such as crushing and fine crushing ores and rocks below medium hardness in mineral processing, chemical, cement, building materials and other industrial sectors. The equipment has large inlet particle size and adjustable discharge particle size. Especially suitable for the coal industry, the use of this machine to break raw coal, as long as the iron, impurities, no need to remove dirt, it can be directly broken, broken materials, uniform particle size, low crushing rate, thus simplifying the coal preparation process, reduce investment and production costs.

Performance Advantages

• 1,The roller crusher is equipped with a replaceable wear-resistant liner, the wear-resistant liner is made of domestic high wear-resistant material, with long service life, easy to damage, convenient maintenance and other advantages, continuous service life can reach more than one year.
• The roller crusher has the advantages of simple and reasonable structure, small space and convenient operation and maintenance. The equipment is equipped with a safety protection device. When accidental metal and iron parts enter the crushing chamber, the protection device will act and the iron parts will leak out and the equipment will operate normally.
• The roll seam of the abrasive roll body of the roller crusher can be arbitrarily adjusted between 1mm and 20mm. After the roll seam is adjusted according to the requirements of the crushing particle size, the crushing particle size can be reliably controlled, and all are discharged from the bottom of the crushing chamber with the ideal particle size.
• The roller crusher adopts combination crushing, rather than impact and impact crushing, and does not produce secondary crushing phenomenon, so the over-crushing rate is very low. Once the center distance of the two teeth roll is fixed and fixed, the material is instantly hard broken, almost no heavy breaking, to ensure uniform grain production.

Working Principle

When working, the broken material is dropped between two rollers through the feed port for extrusion crushing, and the finished product is removed from the bottom discharge port. The roller crusher is equipped with a wedge or gasket adjustment device between the two rollers, and the top of the wedge device has an adjustment bolt. When the adjustment bolt block is pulled up, the wedge block will push the active roller wheel away from the fixed wheel, and the gap between the two roller wheels becomes larger. When the wedge block is down, the active roller wheel becomes smaller under the action of the compression spring, and the discharge particle size becomes smaller. The gasket device adjusts the size of the discharge particle by increasing or decreasing the number or thickness. When the gasket is increased, the gap between the two rollers becomes larger, and when the gap is reduced, the gap becomes smaller.

Question&Answer

Q：What materials does the roller crusher break?

A：The roller crusher can break river pebbles, pebbles, granite, limestone, basalt and other materials, especially suitable for the crushing of guamite, bluestone, steel slag and other materials.

Q：Are there any requirements for roller crusher feed size and discharge size?

A：The roller crusher is suitable for fine sand with feed size of 5 cm and discharge size of 0-5 mm.

Q：How to block the material in the crushing process?

A：The way to solve this problem is to stop the machine to clean up the blocked material, and adjust the feed speed and humidity.
