A pulverizer comprising:

• a housing having top and bottom ends, the housing further having an inlet located towards the top end for receiving input materials to comminute and an outlet located towards the bottom end for discharging pulverized input materials from the housing, the housing including a housing sidewall extending between the top and bottom ends and defining an interior chamber, the housing sidewall comprising:
• an outer structural wall having an inner face and an outer face;
• and
• a housing liner extending against the inner face of the outer structural wall, the housing liner including a plurality of housing liner portions attached to and extending along the outer structural wall, each housing liner portion being detachable therefrom independently from the other housing liner portions;
• and
• at least one pulverizing rotor rotatably mounted in the interior chamber of the housing for pulverizing the input materials fed into the housing via the inlet as the input material passes through the housing from the inlet to the outlet.
