The feed particle size of the roller sand making machine is relatively small, the maximum cannot exceed 40mm, and the discharge particle size is between 2-5mm. As a new type of low energy consumption sand making machine, the double roller sand making machine is often used in sand making production lines; the double roller sand making machine has small size, small floor space, high crushing rate, low pollution, low noise, high efficiency and easy operation. . With the above advantages, the double-roller machine has become popular in the domestic sand making industry, and many sand and gravel field leaders have purchased double-roller machine-made sand.

How to wear the roller skin of roller sand making machine evenly

Controlling the roller skin wear of the roller machine should be considered from the perspective of material feeding, that is, controlling the material before it enters the roller machine to ensure uniform feeding to reduce roller skin wear.

1. The small double-roller sand making machine can be equipped with a material distribution device, that is, by installing a material distributor at the feed port, the material can be evenly distributed on the surface of the roller skin, thereby effectively avoiding uneven wear.

2. Large roller sand making machines need to be equipped with a vibrating feeder. When the materials pass through the feeder, the feeder will disperse the materials evenly through high-frequency vibration before entering the roller machine for crushing work. This can avoid The wear is uneven.

Solution to uneven wear of roller sand making machine

1. If the roller skin has deformed and is no longer smooth, you can remove the roller skin and send it to the manufacturer for processing to make the surface a consistent plane.

2. It is recommended that sand factories with certain capabilities purchase automatic pin cutting machines to perform roll skin cutting directly on site.

It should be noted that after the daily crushing tasks are completed, the sand factory needs to use a blower to clean the sand making machine to prevent impurities from being mixed in other subsequent work tasks. At the same time, safety issues need to be paid attention to when the roller machine is working: During the operation, it is strictly prohibited to probe the head towards the feeding port to prevent the material from jumping out and hurting the head; and when the material is stuck in the material port, it is prohibited to turn the material directly by hand .
