Screw press is a type of sludge dewatering machine press in which the ram is driven up and down by a screw. The screw shaft can be driven by a handle or a wheel. It works by using a coarse screw to convert the rotation of the handle or drive-wheel into a small downward movement of greater force. The overhead handle usually incorporates balls as flyweights. The weights help to maintain the momentum and thrust of the tool to make it easier to operate.

Ceramic filter is a high-tech solid-liquid separation product which is developed basis on the principle of capillary action and combined with the development of ceramic technology. It has the advantages of high filtration efficiency, low production cost, energy saving, clean and environmental protection, etc. It is widely used in the metallurgy, mineral processing, chemical, environmental protection, paper, petroleum, coal, dyes and other industries.

Stone and ceramic processing plants understand the need to recycle their wastewater. Not only does water recycling allow water reuse and significantly reduce water use and costs, but also collecting the slurry aids in meeting environmental laws, regulations and ordinances. Stone and ceramic industry water involves multiple challenges. DOYEN understands the challenges and offers industrial wastewater solutions such as vertical slurry pump, chemical doing machine, mud pump, filter press, and silo systems. Many of today’s consumers are searching for suppliers that utilize environmentally friendly business practices.

Wastewater generated from stone sawing, cutting or polishing process will be drained or pumped to the wastewater tank, and then pumped into the wastewater silo by the wastewater pump. Meanwhile, the chemical dosing machine will make up the preparation with tap water in certain proportion, which will be injected into the wastewater pipeline with rations by the metering pump, and send to the wastewater silo together with wastewater.

Wastewater generated from the ceramic equipments washing or tile squaring, polishing process will be drained to a pool, and big suspensions will be blocked out before the wastewater pool by a mesh. When wastewater level inside the pool reaches a certain upper limit, the wastewater pump will be activated and pump the wastewater to wastewater silo.

Filter Press:  Filter press is a highly efficient, compact, dewatering device for separating solids from liquid slurries in the form of compressed cake. Under the support of the strong R&D strength, DOYEN has developed and produced the manual, mechanical, hydraulic, program controlled automated membrane, quick opening types. In addition, DOYEN adopts advanced technology to develop a series of recessed, membrane and plate and frame filter plates, such as the high temperature and pressure polypropylene membrane filter plate, rubber membrane filter plate, high temperature filter plate and some special purpose filter plates.

It is widely applied in many fields such as coal washing industry, petroleum industry, chemical industry, ceramic industry, pharmacy, food industry, textile industry, printing and dyeing industry, paper making industry, waste water treatment industry etc.
