Basic Information
Scope
Main technical content: 1. This technology uses aluminum sludge, electroplating sludge, iron oxide, and fly ash to press into pellets. It is low-cost and simple to operate. Moreover, aluminum sludge, electroplating sludge, iron oxide, and fly ash can be purchased in large quantities for batch production. With an aluminum sludge and electroplating sludge content exceeding 40%, the use of fly ash can be reduced. Through sintering, the heavy metal components of aluminum sludge and electroplating sludge are solidified in ceramic pellets. The raw materials can be directly obtained from aluminum processing plants or other wastewater treatment plants, with low cost, enabling waste material reuse. The ceramic pellets can be applied to road base materials, concrete aggregates, etc., with wide application prospects. The mixed pellets are formed into blocks. After the sludge ceramics processing, the crushed pellets are transported back for recycling using a crushing device. Through further processing, the recycling rate of waste materials can be enhanced and production efficiency improved. 2. In the enclosed screening machine, the drive motor drives the screening roller through a chain drive mechanism. The ceramic pellets in the cooling cylinder are transported to the left end of the screening roller. The screw blades on the inner surface of the screening roller gradually move the pellets to the right. Due to the larger spacing between the rollers at the left end than at the right end, the dust and fragments in the pellets fall off at the left end. The screening roller rotates to transport the pellets to the right end, where they are graded and screened. The enclosed shell is installed on the outer surface of the enclosed screening machine to prevent dust from being raised during operation. The fan can transport the raised dust to the dust removal room for purification. 3. The dust and fragmented ceramic pellets fall from the bottom of the screening roller to the feed po
