What’s Pulp Equipment?

Pulping equipment is the equipment used to separate plant raw materials into fiber. Pulping methods can be divided into chemical methods, mechanical methods, and chemical and mechanical methods, and the corresponding pulp equipment include digester, grinder, defibrator, washer, bleaching machine, beater and waste recycling equipment.

Paper Pulp Machinery Lubrication

Pulp machinery includes stock preparation equipment and pulp equipment. Lubrication characteristics of Pulp machinery is that the working environment is humid, temperature is high, and there is impact load. It generally requires antioxidant rust-proof lubricants with viscosity of 46-100, better heat resistance, oxidation resistance, anti-emulsification and anti-rust. And the No. 2 or No. 3 composite calcium, sodium or lithium grease with good heat resistant and mechanical stability, and even molybdenum disulfide or graphite grease are also used. The operating temperature of bearings and gears in pulp cooking equipment is high, so the industrial gear oil or grease lubrication is often used. The lubricating parts of pulp machinery are bearing, worm and gear, reducer, closed and open gear, and the involved types are L-HL hydraulic oil and L-CKC industrial gear oil; calcium-based grease, composite calcium-based grease, general-purpose lithium-based grease, graphite calcium and semi-fluid lithium grease and so on.
