Color sand roller dryer

Abstract

The invention provides a color sand roller dryer. The color sand roller dryer comprises a rotatable roller; the roller comprises a feed end and a discharge end; a spiral blade is arranged on the inner side surface of the roller; an inner cylinder is arranged in the roller; one end of the inner cylinder is an intake port; an exhaust port is formed in one side, near the intake port, between the inner cylinder and the roller; hot air flows into the inner cylinder by the intake port, and enters between the inner cylinder and the roller by the exhaust port; a crushing piece is arranged on the outer side of the inner cylinder; the crushing piece comprises separation plates distributed in the peripheral direction of the inner cylinder; limiting plates are symmetrically hinged to the end parts of the separation plates; elastic bodies are arranged on one sides, near the inner cylinder, of the limiting plates; and limiting bodies for limiting movement of the limiting plates are arranged on one sides, near the roller, of the limiting plates.

Description

technical field [0001] The invention relates to the technical field of paint processing equipment, in particular to a colored sand drum dryer. Background technique [0002] Due to its unique aesthetics, colored sand is widely used in construction engineering and interior decoration, etc. Colored sand is divided into natural colored sand and artificial colored sand. Although natural colored sand has luster, smoothness, firmness, wear resistance, and stable performance and Environmental protection and other advantages have been widely used in the field of architectural decoration, but at the same time there are problems such as small color selection, low output, and influence by mineral resources. Therefore, artificial colored sand is generally used in large quantities in the architectural decoration industry. Rich, bright and uniform color, less restricted by mineral sources, and low cost. [0003] Artificial colored sand is generally made by mixing white sand for casting, b...

AI Technical Summary

Problems solved by technology

The traditional drum dryer has the following disadvantages: the materials to be dried are scattered in the drum, and they are turned over in the drum following the rotation of the drum, which is likely to cause partial drying and uneven drying; the air flow in the drum is not uniform, and the material falls in the air for a short time. The surface temperature of the drum is low, and the drying effect on the material is limited
