A composite milling component comprising a composite region of ceramic material and metal is disclosed. The milling component may comprise a lifting member such as a digger shoe of a vertical tower mill, a flight liner of a vertical tower mill, a shell liner of a horizontal axis mill, and/or an end liner of a horizontal axis mill. The composite region may be formed into a portion of the milling component that experiences greater wear than other portions to increase a wear-resistance of the milling component. The composite region may be formed integrally into the milling component during a casting processes of the milling component.

The disclosure discloses a direct-drive sand mill. In various embodiments, the direct-drive sand mill includes: a motor assembly operable to be electrically powered to generate a rotation around a motor rotor rotation axis, a sand mill main body configured to perform a sanding operation, a main shaft configured to extend from the motor assembly to the sand mill main body and to include a shaft section inside the sand mill main body, the main shaft being coaxially aligned with the motor rotor, main shaft support devices positioned at different locations along the main shaft to support the main shaft to coaxially align the motor rotor rotation axis of the motor assembly to the sand mill main body, and multiple flatness detection assemblies positioned at different locations along the main shaft to detect whether the main shaft shifts with respect to the axis of the main shaft.

A rotary milling system includes a rotatable body having a cylindrical portion and at least one variable diameter portion. The variable diameter portion is tapered toward an opening in a sidewall of the rotatable body a discharge grate. The body can include grinding media for abrading a product when the body is rotated. The product can be milled as a dry product or within a liquid medium. The tapered shape of the body urges milled product toward the opening and the discharge grate. The system can include a discharge housing surrounding the discharge grate and a conveying pipe in fluid communication with the discharge housing, with a valve disposed between the conveying pipe and the discharge to selectively allow milled product to be conveyed through the conveying pipe.
