A drying method can be employed. A representative slurry is weighed, then the slurry is dried and weighed, and the slurry concentration is calculated as follows.

PA

C = -------- × 100%

PB

C—concentration of pulp

PA - dry mine weight

PB - pulp heavy

It takes a certain period of time to determine the concentration of the slurry by the drying method to obtain the result, which is not often used on site.

(2) Concentration pot method. In the production site, the volume is usually 1 Litre The concentration pot is weighed after the slurry is filled. When the weight of the pot and the specific gravity of the dry ore are known, the slurry concentration can be obtained by checking the slurry specific gravity and the slurry concentration conversion table.

(3) The slurry concentration indicator scale. It is designed according to the principle of floating and sinking of objects in liquids. It has been used to control pulp concentration in production practice.

Construction Hoist

Construction Hoist (also called Building Hoist, Passenger Hoist, Construction Material Hoist, Construction Passenger Hoist) are an efficient and safe means of transporting people and materials on construction site. They help increase productivity and safety, thereby saving time and money.

Construction hoist is vertical transport machinery driving by pinion and rack, mainly used on construction site for transportation of personal and materials. As a permanent or sub-permanent external elevator, it also applies to store house, dock, high tower, high chimney, etc. There are single cage and double cages hoist. According to the need gets rid of one cage of double cages the hoist will be changed to single cage hoist. SC construction hoist is equipped with reliable electrical and mechanical safety device. It is efficient and safety vertical transporting equipment.

BQ supplying general building hoist, VVVF speed building hoist, modern energy-saving building hoist and other types of building hoist.
