The GP Cone Crushers are based on the original Lokomo crusher design to compete with Hydroset style crushers. Up and down the line up of GP model numbers, YYD carries the GP crusher wear parts for your unit. In most cases, we have the part on the shelf, ready for immediate shipment. GP crusher suppliers often can`t compete with our parts availability! In some cases, YYD has even improved the conventional design of the part–beyond the offerings of conventional GP crusher suppliers–to enhance durability and performance. Whether you need to replace the top bushing, the Thrust Bearing or the Eccentric Bushing- YYD has your GP Series Parts needs covered.

First, the characteristics of traditional drying technology
For example, most of the dehydrated vegetable production still uses the traditional drying method—drying and heating drying method. It has several problems:
1, drying temperature is too high. The traditional drying technology, the drying temperature is not easy to control, the general drying temperature is about 75-90 °C, while the drying process of dehydrated vegetables requires the drying temperature should not exceed 65 °C.
2, drying time is too long. The traditional drying technology requires at least 24 hours per ton of vegetables to be processed. Sometimes it takes longer to rework due to poor drying.
3, large energy consumption. The traditional drying technology, the thermal efficiency is low, about 30% -60%, in the drying process, dry evaporation of water accounted for about 36% of heat, exhaust gas loss accounts for about 58%, dry materials take away heat and Dryer heat loss accounts for 2% and 2%, respectively, and thermal efficiency is only 40%.
Second, the characteristics of heat pump drying technology
1, the drying temperature is low. The production process of heat pump drying technology is about 38-52°C lower than the traditional drying technology, that is, the heating temperature of the heat pump drying technology of the heat pump dryer is about 37°C.
2, the drying time is short. Heat pump drying dehydration vegetable production process, the time required does not exceed about 8h, generally from the preheated to the product 4h can be completed.
3, good drying quality. The vegetables produced by the heat pump drying process have a good color and a stable internal quality.
4, low energy. Since the heat pump drying process utilizes air circulation, the heating temperature is low, the drying time is short, and the capacity is large. Therefore, the heat pump drying process consumes less energy and is a very good energy-saving product.
III. Comparison of economic and technical indicators
The economic and technical indicators of the heat pump drying technology of heat pump dryers are all significantly higher than traditional drying technologies, which are mainly reflected in energy saving, quality, and efficiency.
1, energy consumption:
(1), heat pump drying: According to the test, the heater processing 1t fresh vegetables consumes 20kg of standard coal, heat pump 2.75kW, and the circulating fan consumes 0.2kW. According to the work 4h, the energy consumption is 11.8kW, and the standard coal conversion coefficient is 407g/ (kW?h), 4.803kg standard coal, total energy consumption 20kg+4.803kg=24.803kg (standard coal);
(2) Traditional drying: 240kg of standard coal is consumed, and the power consumption of circulating fan is 2.4kW, and the standard coal coefficient is 407g/(kW?h), equivalent to 0.977kg of standard coal, and the total energy consumption is 240+0.977=240.977 Kg (standard coal). The energy-saving efficiency ratio of the two methods is: (1-24.803/240.977)×100%=90%.
2, quality: heat pump drying process, product quality is stable, good color, no exposed SO2 and other residual substances.
3. Heat Pump Dryer Efficiency: Heat pump drying process products are qualified for moisture content, no rework, and shorter drying time.
