The significance of screening is great, screening operations in the metallurgical industry is indispensable. It can screen the crusher ore fines out portion, the crusher can increase productivity and to avoid excessive pulverization; jig before and dry magnetic beneficiation, often by size sieving the ore into several levels, namely, treatment, Improve the sorting effect; in the concentrator, sometimes the screening operation can also be selected for screening, dewatering screening or washing and sieving. In short, screening operations are an indispensable task in mineral processing.
Marine Electro-hydraulic Windlass
The windlass is installed on the main deck of the ship's bow, which is used for the ship to lift the anchor and drop the mooring cable.
Windlass can be divided into manual, electric, hydraulic, pneumatic, etc. according to the driving form.
The windlass can be divided into several specifications such as φ12--φ120mm according to the diameter of the anchor chain.
Windlass can be divided into single-sided and double-sided according to the distribution of drums.
The windlass is mainly composed of base, bracket, chain wheel, brake, chain wheel, gearbox, electric control system (except manual windlass), etc. Electric windlasses have electric motors, and hydraulic windlasses have hydraulic pump stations.
The main technical indicators of the windlass include the diameter of the anchor chain, the nominal speed of the anchor, the rated load, the supporting load, several levels of speed change, electrical system, etc. The installation of the windlass on the ship should ensure that the wrap angle between the anchor chain and the sprocket is 117-120°.
Electric windlass
The electric motor directly drives the windlass, and the drive shaft is driven by the gear box to work, and the structure is simple; it is generally suitable for windlasses with an anchor chain diameter of 16mm-93mm.
hydraulic windlass
It is suitable for windlass with anchor chain diameter of 16mm-120mm. Hydraulic windlasses are also called electro-hydraulic windlasses. It drives the oil pump with a motor, drives the motor with high-pressure oil, and then drives the transmission gear through a reducer (or no reducer). To make the windlass run, its structure is relatively compact and its volume is small. Now there has been an automatic hydraulic windlass, which is equipped with an anchor chain length sensor. When the anchor chain needs to be thrown out, the windlass will automatically stop; , can automatically decelerate; the anchor will automatically stop when it enters the anchor chain drum and is properly received.
