![]() The prototypical mobile sawmill consists of a bandsaw, conveyor, hydraulic motion components, and a human-operated controller. Portable or mobile sawmills are self-contained mills used by landowners or small sawing businesses. Processes large chunks or pieces of wood into smaller bits for disposal or further processing.ĭresses and sizes rough-sawed lumber on one or more sides, planing boards to an even thickness. Straighten and smooth rough lumber and/or bowed stock by making cuts along the sides of the boards. Handheld saws typically used outside a mill to fell trees. Have multiple blades of a straight-band or circular type to cut logs into cants or make initial "starter" cuts. Used to accommodate large logs and make cuts more precise than those done by circular saws. Pass boards to other equipment types and reduce operator interaction.īlades consist of a continuous metal band attached to two or more wheels rotating on the same plane. Remove bark from a log before processing drum, Rosser head, and ring types are common. Used to transport and position logs before they are cut and processed. Stackers, log turners, sorters, and conveyors The table below lists some common equipment categories and types. Sawmills combine disparate equipment types to move logs to and from the mill, prepare them for processing, make cuts, and dispose of waste. Dried pulp is then cut, stacked, and shipped as fiberboard. The chips are rendered into a porridge-like pulp through steam treatment or digestion using chemical processes. Pulp mills debark pulpwood logs and grind them into small chips. Fiberboard is used in furniture-making or shipped to paper mills for further processing. Pulp mills produce fiberboard by using specialized processes and equipment. Stud mills are specialized mills that produce studs, which are vertical support members found in most building walls. Some hardwoods, such as mahogany and cherry, are prized for their attractive aesthetic qualities. Hardwood is preferred for woodworking, is often used in furniture-making, and is more expensive than softwood. Hardwood mills process ash, oak, maple, birch, and other angiosperm trees. Softwoods are commonly used in furniture and outdoor building materials. Cedar, pine, redwood, and fir are common softwood trees. Softwood refers to timber from gymnosperm trees and does not necessarily denote a "softer" material. Softwood mills convert softwood into lumber and other finished products. Sawmills may be classified by the type of wood they convert or the end product they produce. The lumber is then inspected, tagged, and shipped to market. A planer smooths the lumber surface to a uniform width and thickness.
