The specifications above apply to the standard model 2PGC450×500. Non-standard customization is available based on specific material characteristics and user requirements.

How Does Chemical Cake Toothed Roll Crusher for Pigment Paste Work？

Chemical cake toothed roll crusher for pigment paste operates on the principle of dual toothed rollers rotating in opposite directions.

Two motors drive two high manganese wear-resistant alloy toothed rollers toward each other in counter-rotation. Material entering the V-shaped crushing chamber between the rollers is simultaneously subjected to compressive and shearing forces.

Through the combined actions of compression, shearing, and grinding, large pigment cake blocks are fractured along natural cleavage planes to the desired particle size, then discharged through the outlet.

The gap between the two rollers can be adjusted via the regulating mechanism to control output particle size. The equipment operates in a non-continuous crushing mode, with material experiencing intermittent force application between the teeth, reducing instantaneous energy consumption.

What Material Scenarios Are Suitable for Chemical Cake Toothed Roll Crusher for Pigment Paste？

Chemical cake toothed roll crusher for pigment paste serves the coarse crushing pretreatment of pigment pastes, dye filter cakes, and pigment paste filter cakes. It can also process low-hardness paste materials including coating color pastes, printing ink pastes, chemical additive filter cakes, and diatomaceous earth filter cakes.

Processing performance across different material types:

Organic pigment pastes with 50% to 60% moisture content achieve crushing uniformity above 90%

Inorganic pigment pastes achieve processing capacity of 35 to 45 tons per hour with uniformity maintained above 88%

Dye filter cakes with 55% to 60% moisture content demonstrate material flow with virtually no roll sticking

Application industries include fine chemicals, coatings, printing inks, and dyes, specifically in mid-to-late stage production lines.

How to Determine If Chemical Cake Toothed Roll Crusher for Pigment Paste Is Suitable for Your Material？

Users may submit small material samples for actual crush testing, focusing on three indicators: material flow smoothness through the rollers, uniformity ratio of crushed particles, and visible adhesion residue on roller surfaces.

Organic pigment pastes with 45% to 60% moisture content achieve the highest throughput rates with uniformity exceeding 90%. Materials with moisture content below 30% should be spray-moistened before feeding. Feed material exceeding 300 mm requires pre-crushing before entering the equipment. Materials containing hard impurities should be equipped with magnetic separation devices before feeding.

Selection note: Based on feedback from multiple users, the common issue after one year of operation is not roller plate wear but bearing seal aging leading to lubricant leakage. Inspection of bearing seal condition every 2,000 operating hours with timely seal replacement is recommended to extend equipment overhaul intervals.
